EXECUTIVE SUMMARY



This Revised Final Proposal (Final Proposal) submitted by Ameresco Federal Solutions, Inc.
(Ameresco) is for the implementation of two biomass Energy Conservation Measures (ECMs) at the
Department of Energy’s (DOE) Savannah River Site (SRS), located in South Carolina, approximately 18
miles south of Aiken and 20 miles east of Augusta, Georgia. The ECMs are being proposed under the
authority and terms of the DOE Biomass and Alternate Methane Fuel (BAMF) Energy Savings Performance
Contract number DE-AM36-02-NT41457 as modified by DO RFP # DE-RP09-09SR22572, dated February 26,
2009. This Revised Final Proposal including technical, pricing, and management data shall remain
valid through June 15, 2009.



The proposal consists of two Energy Conservation Measures (ECMs). ECM 1 provides for the turnkey
installation of a new Biomass Cogeneration Facility with a design capacity of 240,000 pounds per
hour (PPH) of steam and 20 megawatts (MW) of electric power. The new facility will replace the
existing
 D Area coal-fired cogeneration plant. ECM 2 includes the turnkey installation of two 10,500 PPH
steam heating facilities; one to be located in the K Area and one to be located in the L Area.
These systems will replace the aging fuel oil-fired packaged boilers currently serving the K and L
Areas of the site.



The existing D Area cogeneration plant produces both steam and electricity that is consumed on
site. The steam is delivered through a large distribution pipeline that runs several miles from
the plant to the end-user facilities. The plant also produces approximately 15 MW of electricity
that is consumed by DOE facilities on site. The 1950s era plant is fueled by coal and in need of
significant modifications to bring the plant into compliance with current environmental
requirements as well as to be a reliable source of energy. The proposed Biomass Cogeneration
Facility, sited near the existing steam interconnection at the intersection of Burma Road and C
Road, will significantly reduce the distance from the plant to the end-user, resulting in improved
operating efficiency. The new facility will have enough capacity to satisfy all of the site’s
steam requirements and a significant portion of the electrical demand which will allow for the D
Area plant to be shut down.



Currently, the existing heating plant in the K Area provides steam for both the K and L Areas.
Steam is delivered from the K Area plant to L Area facilities through a 6”, 2.5 mile pipeline. ECM
2 provides for replacing the K Area plant with two 10,500 PPH boilers — one boiler located in K
Area and one located in L Area — eliminating the need to use the 2.5 mile distribution line. The
existing K Area plant and the steam line will be shut down.



Clean biomass and bio-derived fuels (BDF) will be the primary fuel source for all of the new
boilers. The clean biomass consists of various types of forest residues, and the BDF consists
primarily of scrapped vehicle tires. Fuel deliveries will be received by Ameresco staff at a fuel
handling yard located within the Biomass Cogeneration Facility site at the Burma Road/C Road
location. The fuel handling yard includes a fuel receiving, storage, and processing area that will
serve the Biomass Cogeneration Facility and the K and L Area Heating Plants. Fuel deliveries to
the K and L Area Heating Plants will be made by Ameresco staff on an as-needed basis from the
central fuel yard.

The use of renewable energy fuel sources provides many positive economic and environmental benefits
to the SRS and the local community, while providing significant energy and cost savings to SRS.
The savings result from fuel switching (coal to biomass), reductions in line losses by locating the
new cogeneration facility and heating plants closer to end-user facilities, and improved
efficiencies from new equipment sized to better match existing load requirements. Key
environmental benefits of the project include:





	 	l	 	 Over 2,000,000 MBtu/yr of thermal renewable energy production and a minimum
generation of 77,000 mWh (264,444 MBtu) of green power.
	 
	 	l	 	 Annual Energy Savings of approximately 500,000 MBtu/yr
	 
	 	l	 	 No-cost Renewable Energy Credits (RECs)
	 
	 	l	 	 Decrease of water intake from the Savannah River by 1,412,000
kgal/yr, supporting water conservation efforts in the regional drought situation.
	 
	 	l	 	 Reduction of 400 tons/yr of Particulate Matter (PM) emissions
	 
	 	l	 	 Reduction of 3,500 tons/yr of Sulfur Dioxide (SO2) emissions
	 
	 	l	 	 Reduction of 100,000 tons/yr of Carbon Dioxide (CO2) emissions
	 
	 	l	 	 Support of the South Carolina Biomass Council Goals




Ameresco proposes to provide a turnkey package of design, permitting, and installation. Ameresco
will also take responsibility for the operation and maintenance of the cogeneration facility and
heating plants throughout the contract term. Table ES.1 below provides an overview of project
economics (as shown on Schedule DO-4) for Performance Period Year 1.

Following contract award, the detailed design will be completed and construction of the new
facilities will take place. It is expected that thirty months from the date of contract award will
be required to complete the final design and construction of the main Biomass Cogeneration
Facility. However, Ameresco expects that the K and L Area Heating Plants can be constructed within
18 months of contract award. For this reason, Ameresco proposes an early acceptance of ECM 2.

1.0 ECM 1 DESCRIPTION




1.1 ECM Summary Schedule DO-4



Pricing Schedule DO-4 is included in Section 6.0, Proposal Pricing Information.



1.2 ECM #1:Biomass Cogeneration Facility




1.2.1 Detailed Description of ECM



1.2.1.1 ECM Summary



This ECM comprises the design and construction of a Biomass Cogeneration Facility
(cogeneration facility) to be located to the northwest of the main distribution steam
interconnection at the intersection of Burma Road and C Road. The steam produced from the facility
will be exported to the 200 Areas via the existing distribution system; the green power generated
will be exported to the SRS electrical distribution system via a new interconnection at the
existing F Area substation. The scope of work includes the installation of the cogeneration
facility and all equipment, the site work, and the necessary utility interconnections required for
plant operation. There are three additional items included in the scope (design drawings for these
items to be provided following contract award):





	 	1)	 	The procurement and installation of a new skid-mounted river water pump and new pumping
systems controls at the river water pump house, Building 681-3G.
	 
	 	2)	 	Rework of the electrical feeder from the TNX area to the South Carolina Electric and
Gas (SCE&G) utility line at the D Area.
	 
	 	3)	 	Relocation of the existing L Area capacitor bank.




The cogeneration facility will be sized to provide a continuous supply of steam to site end-users
(based on current and future load projections as presented in the SRS Site Projection Profile
provided by the Government) while optimizing the quantity of green power generated. The system is
designed using applicable national codes and standards for power plants and specific site standards
(refer to Section 5.2). Previously, conceptual design drawings were submitted to the site for
review prior to issuance of this final proposal; a draft version of the “issued for pricing”
drawings is included in Volume III of this proposal. Finalized “issued for construction” drawings
will be submitted to the government for concurrence throughout the first year of the construction
period, as major equipment items are ordered and the design drawings are finalized.



This ECM will provide an estimated savings of over $33 million in the first year of operation
through the offset of coal purchases, and reduced O&M from the elimination of the existing D Area
Power Plant and electrical substation. The renewable energy-fueled cogeneration facility will also
provide renewable energy credits (RECs) to SRS at no cost. For purposes of receiving credit for
implementing this renewable energy initiative, the RECs attached to ECM 1 and ECM 2 will belong to
the Government and will not be claimed nor sold by Ameresco.

In addition to the design and construction, Ameresco will retain responsibility for fuel delivery,
operations, maintenance of the cogeneration facility and site; repair and replacement of the
cogeneration facility equipment; air and effluent outfall emissions compliance for the cogeneration
facility; and monitoring, measurement, and verification (M&V) throughout the contract term. Refer
to Section 5.2.7 for details on Ameresco’s Site Operations.




1.2.1.2 ECM Design Process



The proposed cogeneration facility will provide steam and power to the SRS site. Several
configurations and energy models were analyzed during the Detailed Energy Survey (DES) phase to
determine the final system sizing and system components. The optimal equipment selection and
sizing was selected to balance the current and future thermal needs of the site while maximizing
green power generation. Final selection resulted in a system composed of two (2) biomass bubbling
fluidized bed boilers, each with an output capacity of 120,000 PPH (240,000 PPH plant total) steam
and one (1) condensing steam turbine/generator with an output design capacity of 20 MW.



Superheated steam will be produced in the new combustor/boiler systems at 850 pounds per square
inch gauge (psig) and 825 degrees Fahrenheit (°F), for delivery to the turbine/generator
unit. Steam is extracted at a reduced pressure (385 psig nominal) from the turbine to meet the
demand of the site, as well as for parasitic use. As the primary purpose of the cogeneration
facility is to provide a continuous supply of steam, the amount of steam extracted from the turbine
will vary to meet the site demand. As the extraction rate varies with the site steam demand, the
gross power output from the turbine/generator will also vary. Based on future steam load forecasts
as presented in the SRS Site Projection Profile provided by the Government (Table 1.1 below),
output from the turbine/generator will range from 8 to 20 MW. The net power exported will vary
from 5 to 17 MW as the new cogeneration facility’s in-house (parasitic) loads will range between
2-4 MW. A detailed basis of design is included in the following subsections.



Site



The location of the new cogeneration facility was selected during the initial feasibility study of
the project. The facility will be located approximately 0.5 miles northwest of the intersection of
Burma and C Roads on a 30 acre site. The development on the site will include the following major
areas: 1) the fuel handling yard, 2) the boiler/combustion system, 3) the power plant, 4) the
cooling tower and outfall piping, and 5) the administration building and site parking. The
placement of the cogeneration facility on this site was optimized to minimize fuel handling
conveyor runs, and to ensure critical systems are located near the operator control room. The
layout was also arranged to make use of the natural topography of the land where possible to
minimize disturbance to the environment. The location and layout of the facilities were also
optimized to the extent possible with regard to interfaces with site utilities (described in
Section 1.2.3), a new storm water collection system and outfall, and the new site fire protection
system.



The storm water system is designed to collect storm water from the impervious portions of the site.
These include building run-off, roadway run-off, and equipment run-off. The system will include a
series of

catch basins to collect the storm water. The site will be graded to direct the storm
water to each of the
 catch basins. The catch basins will be interconnected by 6”, 8”, and 12” piping. A manhole will
be included to provide maintenance access at each change of direction. Ultimately the storm water
will be directed by gravity to a storm water detention pond which is sized to hold the expected
rainfall peaks in the area. The pond will be complete with a liner and slotted spillway to enable
a controlled release of water to the outfall. The system will be installed with a monitoring
system to measure flow, pH, and conductivity. Major components include catch basins, piping,
manholes for maintenance access, lined 165,000 gallon detention pond, monitoring system, and the
24” outfall.



Extensive soil testing was completed on the site to determine the conditions for the soil and
recommended design for structural support of equipment, facilities, and new pavements. The soil
composition is primarily sand with light clay and therefore requires treatment of the site with an
engineered fill prior to foundation work. A copy of the complete soil report is included in
Appendix A of this proposal.



Logistics of site traffic are designed to allow biomass delivery trucks and other facility traffic
to enter the site from Burma Road. The existing gravel portion of Burma Road will be paved up to
the entrance of the site. Delivery trucks will enter the facility from the Burma Road entrance
using a new deceleration lane, and exit the facility via a new one-way exit along the former route
of Old Burma Road (currently an unmaintained dirt pathway between Burma and C Roads). All other
facility traffic will enter into the new parking lot or the on-site access road, and may then exit
back to Burma Road or use the new one-way exit to C Road.



Delivery trucks will traverse the entrance road to the fuel yard, and after fuel delivery will exit
via Old Burma Road, which will be re-cleared and paved up to C Road at the existing 3-way
intersection of C Road and the entry to the F Area. Old Burma Road will be designated and marked
as a one-way thoroughfare in accordance with South Carolina Department of Transportation (SCDOT)
standards, and the traffic signal at the existing 3-way intersection on C Road will be converted to
a new 4-way intersection. This arrangement provides for a safe traffic flow and allows delivery
vehicles to make left-hand turns across traffic only at a signal-controlled intersection. Also
included in the site scope of work is the removal of the curbed median at the existing 3-way
intersection, and the installation of new loop-control vehicle sensor wiring beneath the pavement
at the new 4-way intersection. Figure 1.1 is an illustration of the overall site layout; the
specific areas within the site are further described in the following pages.

Fuel Handling Yard



The fuel handling yard will serve as the delivery point for all fuel supplies for the cogeneration
facility, as well as the two heating plants serving the K and L Areas. Approximately 40-60 trucks
will enter the site daily (at staggered delivery times) at the Burma Road facility entrance. The
entrance to the yard will include truck scales for weigh-in of all fuel sources for tracking
deliveries. Beyond the entrance will be the unloading equipment, fuel storage area, and the fuel
handling and processing equipment.



For fuel handling operations at the cogeneration facility, front-end loaders and augers/conveyors
will be used at various points in the yard to move fuel between stations, through the yard area,
and into the combustion systems. The biomass wood fuel will be unloaded using three (3) automated
hydraulic truck-dumping stations. The truck-dumpers discharge into a reclaim pit, where the fuel
will be lifted to the first transfer conveyor. The fuel is then screened and processed through a
hogger and disc screen onto a second transfer conveyor. The fuel can then be transferred into the
outside storage area or directly into the metering bins of the combustors. Stored fuel will be
stacked in the outside storage after delivery from the transfer conveyor by use of a circular
stacker/reclaimer. In addition to stacking the fuel, the stacker/reclaimer functions as a
reclaimer to transfer the fuel from the storage stack to the fuel metering bins prior to entering
the combustors.



The total available outside storage for clean biomass is approximately 15 acres, allowing for 30
days of continuous operations without replenishing the on-site fuel storage. The scrap vehicle
tires brought to the site will be unloaded and processed in a separate area before being augured
into a separate reclaimer. The separate unloading area and reclaimer allow for better process
control through mixing with the biomass fuel, and also help to quantify BDF usage in meeting the
requirements of the South Carolina Department of Health and Environmental Control (SCDHEC) air
permit with regards to limits on BDF combustion.



Fuel supplies for the K and L Area boilers will be loaded at the cogeneration facility fuel
handling yard and trucked by Ameresco staff to the K and L Area heating plants as needed, since the
heating plants operate only during a limited heating season. One truckload per day is the
estimated maximum usage at both the K and L Area heating plants during the coldest periods.



Proposed Fuel Yard Components include:





	 	l	 	 Two (2) Truck scales
	 
	 	l	 	 Three (3) Hydraulic truck dumps and reclaimers
	 
	 	l	 	 Front end loaders

The final design of the system was developed with primary consideration given to the following:
handling and processing of multiple fuel types; safe and plentiful fuel storage area on site;
minimized maintenance requirements; reduced downtimes; and provision for flexible operation of the
overall systems.



Combustion/Boiler System



The combustion/boiler system includes the components from the fuel feeders to the exhaust stack,
including the boiler auxiliaries. A bubbling fluidized bed (BFB) combustion technology will be
used for this project. BFB technology uses high pressure air to fluidize a 2-3 foot bed of sand
(inert material) in suspension. The fuel source is fed into the system through air spouts and
mixed into the suspended bed. The system operates using 30-40% theoretical combustion air to
reduce bed temperature and minimize nitrogen oxide (NOx) emissions.



BFB technology is preferable for biomass fuels due to its ability to better tolerate various fuel
types, as well as larger variations in both fuel mixture density and moisture content. BFBs have
the advantage of reduced air emissions due to a more stringently controlled temperature in the
combustion process (1400-1600oF). Compared to stoker technology, the bubbling bed
offers lower uncontrolled air emission rates, resulting in a lower investment for downstream air
pollution control system components. BFBs require less maintenance than the stoker boiler,
resulting in less downtime and lower ongoing costs.



[**]. The EPI system is shown in Figure 1.2. The EPI combustor/boiler offers the following
benefits in this size range of BFB equipment:

Figure 1.2: EPI Fluidized Bed Energy System







Two identical BFBs will be installed in the new cogeneration facility. Both boilers will be sized
for a total design input of 372 MBtu/hr (186 MBtu/hr per boiler) and an output of 240 kpph (120
kpph per boiler). The bubbling bed boiler will produce steam at 850 psig, 825°F. Steam
generated will go through a condensing turbine when generating electricity, or through a pressure
reducing valve (PRV) station which will reduce the pressure to 385 psig. Steam required by the
site and for the cogeneration facility
deaerator (DA) tank will be extracted from the turbine at 385 psig. The 385 psig steam will be
distributed to the existing system via the interconnection to the existing steam header located
just across the street from the new cogeneration facility. Additionally, full capacity fuel oil
burners will also be installed in the combustor to serve as a back up fuel source in case the
biomass feeders are down. Refer to Section 1.2.1.3 for details of SRS steam demand.

Figure 1.3: EPI Fluidized Bed Cell







Fuel will enter into the combustion metering bins from the fuel transfer conveyors. Metered fuel
is discharged through isolation slide gates and into the fuel spreaders. The spreaders distribute
the fuel across the fluidized bed. The fluidized bed cell as shown in Figure 1.3 includes the
equipment to accept, distribute, and mix air, fuel, and limestone in a high temperature thermal
oxidization environment. The system is designed in accordance with National Fire Protection
Association (NFPA) Section 850. Underbed air and overfire air distribution systems are provided to
allow proper air flow for uniform combustion, to provide cooling of tramp material, and to optimize
overall bed temperature.



The EPI system is specifically designed to include a bed recycle system to accommodate wood and
tire derived fuel containing wires. The tire bed system is a fluidizing bed bottom, wire
separation, and screening system designed to handle high concentrations of wire left over from the
thermal oxidization of shredded tires and tramp material. The metal is recovered from the rest of
the tramp material and bed media then discharged to the hopper for recycling.

Each of the biomass boilers will include a gas handling system, which includes an induced draft
(ID) fan to pull the boiler flue gas through the economizer. The ID fan exhausts into a fabric
filter baghouse and then to an integral exhaust stack.




Pollution Abatement Control



The fluidized bed system provides an environment to optimize destruction of hazardous air
pollutants and volatile organic compounds. Additional pollution abatement control is included in
this system to comply with air emission requirements.



Particulate Matter Control: Particulate in the gas stream is captured in a pulse-jet baghouse
system. The baghouse captures particulate matter from the flue gas and has removal efficiencies of
99.9+%. The flue gas will then exit through a stack adjacent to the ID fan and baghouse located
just outside of the new cogeneration facility.



Nitrogen Oxide Control: The flue gas from the boiler will be treated in the combustion system
using selective non-catalytic reduction (SNCR) technology to reduce nitrogen oxides. Using the
SNCR will reduce NOx rates to 0.12 lb/MBtu. Urea is injected into the furnace typically above the
over-fire air ports, reacting with the oxides to form nitrogen and hydrogen.



Sulfur Dioxide Control: Since tire derived fuel will be used as a fuel source, each biomass boiler
will also have a bed additive system. The bed additive system will introduce limestone into the
fluidized bed cells in order to reduce sulfur dioxide and other acid emissions. Sulfur dioxide
will be controlled to less than 0.2 lb/MBtu in order to comply with air permit conditions.



Each boiler will include an exhaust stack. Each stack will include an aviation lighting system,
and a continuous emissions monitoring system to measure the stack emissions and provide data
reporting. The system will monitor carbon monoxide (CO), oxygen (O2), NOx,
SO2, reagent slip, and opacity. The data is recorded in the facility supervisory
control and data acquisition (SCADA) system.




Ash Handling System



The fuel will primarily consist of clean biomass sources; therefore, the ash content is expected to
be low, less than 1.0-3.0% of the fuel burned. The ash stream consists of a bottom ash stream and
a flyash stream. Bottom ash will be automatically removed from the biomass boiler with mechanical
conveyors and augered into a hopper outside of the building. Fly ash will be collected at multiple
points along the flue gas exhaust train, including boiler hoppers, mechanical dust collector
hoppers, and baghouse. The flyash system will be a mechanical pneumatic system consisting of
rotary air-lock valves, screw conveyors, drag conveyors, and storage container. The ash collection
hoppers will include water nozzles to keep ash wet and minimize dusting into the plant area.



The ash generated from combustion will be delivered to the landfill or taken off site to potential
end-users. Ameresco will be responsible for ash removal, and the cost is included in the
performance period expenses.

Power Plant



The power plant will house the boiler feedwater system, the water treatment system, the chemical
treatment system, and the steam condensing turbine. The cooling tower and emergency generators
will be located outside to the west of the power plant. The building will be a pre-engineered
two-tiered metal building and 16,000 sq ft in size. Within the power plant there will be a control
room, break room, storage, chemical and sampling area, and the motor control center. The equipment
components are described in the sections below.




Boiler Feedwater System



A feedwater system will pressurize and deliver deaerated boiler feedwater from the DA tanks and the
desuperheater to the boilers. The boiler feed pumps will pull the heated water from the DA tanks.
Since there is no condensate return infrastructure in place, the DA tanks will receive makeup water
from the water treatment system and from the condensate tank. The feedwater will be delivered to
the boiler at 850 psig and 370oF. There are 2 DA tanks for the boilers; one will be
used as a backup.



Components of the primary feedwater system include the following:





	 	l	 	 Three (3) Boiler feed pumps and motors
	 
	 	l 	 	Two (2) DA tanks with instrumentation and trim
	 
	 	l	 	Piping, valves, and controls





Water Treatment System



River water will be used as the source of water for the process water, regeneration water, and for
fire system water. The river water will be filtered through carbon filters and softeners. Process
water will be treated using Reverse Osmosis (RO) technology and then deionized through a mixed bed
system. This system was designed based on samples collected from the Savannah River during the DES
and from water analysis reports for the D-Area plant. The peak make-up requirement to the
cogeneration facility is

Chemical Feed System



Chemical feed systems are designed for the boilers to provide protection from corrosion, scale
formation, circulating water biofouling, and to provide pH control. Specific internal boiler water
treatment programs will be designed during the implementation phase. Chemical equipment includes
the following:





	 	l 	 	Boilers

1.2.1.3 ECM 1 Operation



ECM 1 will be operated continuously to produce steam and power for SRS, with the primary
mission of meeting the Annual Steam Guarantee (ASG). The ASG is the total amount of steam output
from the biomass boilers as defined in Section 1.2.7.4. During normal operation, steam produced
from the boilers will flow through the condensing steam turbine. Steam required for the
cogeneration facility auxiliaries and the export steam required by the site will be extracted from
the turbine. The balance of steam will continue through the turbine to generate additional green
power. As required by SRS, the cogeneration
facility will be operated to provide steam at 350 psia through the existing Government-owned
distribution system to the users in the F and H Areas.



Scheduled outages will not exceed one per year and only one boiler will be taken down at a time for
planned maintenance. In the unlikely event that both boilers are inoperable, Ameresco has made
provisions and connections for bringing temporary boilers to the site to ensure the supply of
steam.



Projected steam demands of the site are based on information provided in the SRS Site Projection
Profile provided by Government personnel. The projections upon which the cogeneration facility
performance model is based was provided by government personnel in the SRS Site Projection Profile
and shows that annual steam loads will differ for the next 20 years as shown in Table 1.1. Due to
these changes in operation and the anticipated variation in weather from year to year, it is
proposed that the new cogeneration facility will be operated to produce a fixed quantity of steam
each year, the ASG. As the demand for exported steam decreases, the amount of green power
generation will increase, up to the ASG.

Ameresco staff will be responsible for operating and maintaining the cogeneration facility
throughout the contract term as detailed in Section 5.2.7.1, and the cogeneration facility will be
continuously manned by
Ameresco staff as described in Section 5.2.7. However, this Final Proposal excludes any operation
and maintenance obligations on the part of Ameresco except as detailed in Section 5.2.7.1




1.2.2 Location Affected



During the Initial Proposal kickoff meeting, the Government presented three sites as potential
locations for the new cogeneration facility. The selected site is shown in Figure 1.4 below and
was agreed upon by SRS, the M&O Contractor, and Ameresco based on an evaluation of many factors,
including distance to existing utility connections, available acreage, accessibility, security
concerns, and environmental impacts. A site-use permit was obtained and is currently being amended
to include the electrical feeder to the F Area, the river water piping tie-in from the C Area, the
process water outfall to Upper Three Runs Creek, and improvements to the Old Burma Road/C Road
intersection.

1.2.3 ECM 1 Interface with Government Equipment



Title to all Ameresco installed equipment will transfer to the Government at the time of
Government acceptance of an ECM. Title to the biomass fuel will transfer to and vest in the
Government simultaneously with Ameresco’s receipt of the biomass at the fuel handling yard. For the
sake of clarity, ECM 1 will interface with existing Government equipment at the utility
interconnections as described in this section. The installation of utility interconnections
required for the new cogeneration facility are included in the project implementation cost and the
installation will be Ameresco’s responsibility; however, the SRS M&O Contractor will retain O&M
responsibility including repair and replacement for the utility interconnections and utility
distribution systems. Table 1.2 provides a summary of the utility interface and the scope of O&M
responsibility for the utility systems. Ameresco and the SRS M&O Contractor will enter into an
agreement that will provide the cogeneration facility with utility services to include river water,
sanitary sewer service, backup electrical power, and domestic water service. A Power Services
Utilization Permit (PSUP) form will be completed by Ameresco prior to construction of utility
interconnections. Utility meters will be installed to measure usage. It is proposed the
Government will incur the cost for the cogeneration facility’s non fuel utilities. These Post-ECM
Implementation Costs have been factored into the annual savings. The annual consumption and costs
of the utilities are shown in Table 1.6, and the unit cost used for each utility is shown in Table
4.2. Refer to Section 5.2.7.1 for operation and maintenance responsibility.



Infrastructure services (site facility operations and maintenance) are primarily the responsibility
of the Site M&O Contractor. M&O Contractor personnel operate and maintain the SRS utility systems
and manage site environmental programs. On site DOE personnel are charged with oversight of M&O
Contractor operations although M&O Contractor personnel often render project or program decisions
for the Government. Therefore, for purposes of this proposal, the use of the term “Government” is
applicable
to DOE and M&O Contractor. For example, the term “Government caused delays” includes any delays
caused by government and/or M&O Contractor personnel. Although the M&O Contractor makes
operational decisions for the systems they operate and programs they manage, only DOE personnel,
i.e. Contracting Officer and Contracting Officer’s Representative (COR) will provide project and
program decisions affecting work performed by Ameresco or Ameresco subcontractor personnel
resulting from this proposal.

Steam Distribution System



Steam produced from the boiler at 850 psig and 825°F will flow through the turbine, or
through a pressure reducing valve (PRV) and desuperheater if the turbine is not operating. From
the turbine or PRV, the steam will be exported to the SRS distribution system, with a small
percentage going to the cogeneration facility DA tanks. Flash steam from the continuous blowdown
flash tank is supplied to a low pressure header to supplement the steam requirements of the DA.



The steam exported to the distribution system will be delivered at 350 psig 450oF. A
new 12” carbon steel pipe will be routed above-ground from the cogeneration facility (exiting from
the turbine or PRV station) to the existing steam line located across Burma Road. A steam meter
will be installed in the line to measure steam exported from the cogeneration facility, as well as
a steam meter on the flow exiting the boilers to measure the total amount of steam produced. The
new cogeneration facility export connection is approximately 3 miles closer to the F and H Areas
than the existing D Area plant, providing increased distribution system efficiency from decreased
line losses. The approximate point of interconnection is shown in the photograph below:

Domestic Water



A 2” domestic water line will be installed to serve plant potable water needs such as bathrooms,
utility sinks, showers, and eye wash stations. The new water line will connect to the existing
domestic water

header located outside of the nearby industrial water treatment plant, located
approximately 0.3 miles east of the cogeneration facility. Domestic water usage is expected to be
minimal (5-10 gpm) and used for sink, lavatory, and maintenance requirements. Annual consumption
is expected to be approximately 2600 kilogallons (kgal). The domestic water interconnection will
be designed per M&O standards and permitted as required by the SCDHEC.



Process Water



River water will be used as the water source for all process and fire water. The process water
usage includes boiler feedwater, cooling tower makeup water, water treatment regeneration cycles,
and cogeneration facility service water. The river water will be supplied from Building 681-3G,
the water pump house, through an existing distribution system and pump station. A new 12” ductile
iron line will be routed underground from the existing C Area valve house (refer to Figure 1.6) to
the cogeneration facility site following the route of the abandoned steam line from the C Area, and
then diverting off of the route through existing vegetated areas to the site. Routing through the
vegetated area will reduce the new distribution pipe route by approximately 1/2 mile. The specific
routing is shown on the site drawing which is included in the drawing package (Volume III). The
peak make-up requirement to the site is 2200 gpm; this would occur if the system was operating at
full capacity and if all the regeneration cycles of the water treatment system were occurring at
the same time. Normal operations will use 600 gpm. Annual river water consumption will average
around 450,000 kgal.



To ensure there is adequate redundancy and back-up for the site river water source, in addition to
the installation of the new distribution line a new pump skid (identical to the P-10 skid) will be
installed to replace the pump, P-4, located inside the water pump house (Bldg 681-3G). The new
pump will be used as a backup for P-10 and be designed with a 19.8” impeller size (600 hp motor.)
Other components to be installed with the new pump include:





	 	l	 	 Rework of the existing suction pipe
	 
	 	l	 	 Installation of isolation valve in suction pipe
	 
	 	l	 	 Installation of flow control valve & flow meter
	 
	 	l 	 	Installation of instrumentation and valves setup (duplicate system to the P-10 skid)
	 
	 	l	 	 Control modification to allow the pumps to automatically operate based on
system requirements

Site Outfall



A new 24” high density polyethylene pipe will be routed from the cooling tower basin to Upper Three
Runs Creek. The pipe will be installed underground and follow the natural topography of the land.
A new outfall structure will be constructed next to the cooling tower to allow for flow monitoring
and effluent testing. Process waste water and the storm water runoff will be discharged to the
outfall. The storm water system includes collection piping to catch basins which will divert the
storm water to the site

retention pond. The retention pond will discharge to the outfall. The
outfall will be permitted under the site National Pollutant Discharge Elimination System (NPDES)
permit.



Sanitary Sewer



The bathrooms and fixtures located in the cogeneration facility and in the administration building
will connect to the existing sanitary sewer system via a 4” polyvinyl chloride (PVC) pipe and be
pumped using a new lift station. The line will connect upstream to the 607-91G lift station
located approximately 0.3 mile east of the cogeneration facility. The sanitary sewer
interconnection will be designed per M&O standards and permitted as required by the SCDHEC. Annual
discharge is expected to be 2,600 kgal.



Electrical System



Power will be delivered to the existing F Area substation at 13.8 kV from the cogeneration
facility. The power feeder from the cogeneration facility will be approximately 7,600 feet and
will be routed in a combination of overhead pole mounted transmission line and underground duct
bank where required in the F Area. The feeder will connect to an existing spare breaker cell in
the metal-clad switchgear lineup at 251-F. The breaker cell shall be unit 101A, 101B, 206A, or
206B as deemed suitable by Ameresco and the Government. The interconnection scope of work includes
a compatible circuit breaker, multifunction utility-grade numerical relay and instrumentation, and
a 15kV class line potential transformer (PT) (either outdoor on feeder or indoor in a top-hat
structure added to the existing switchgear). Existing bus PT secondary sources and existing
station direct current (DC) battery sources are to be tapped as-is without improvement. Ameresco
will utilize as-is or improve existing lockout relays and circuit breaker auxiliary contacts where
no spare contacts or similar status points are available. Where such improvements are not possible
due to the limitations of existing equipment, Ameresco will propose a solution to the Government
(e.g. interposing relays, SCADA outputs, etc.). Ameresco assumes that the subject devices either
as existing or improved, sufficiently indicate the operation of distribution and transmission level
switching to determine when the generation system is unintentionally islanded from the utility
source. Where transfer trip capability is required or determined to be best practice for
protection of the proposed generation system, transfer trip facilities are to be derived from
existing utility protective relaying
equipment installed at 251-F. The scope excludes special or upgraded SCADA communications between
251-F and electrical utility operator. This scope is limited to the feeder circuit breaker at
251-F used to service the proposed generator plant and the primary protection described. The scope
does not include other feeders at 251-F or any other upstream devices that are not impacted by the
project (e.g. transformer secondary or primary protective devices and features, transmission-level
protective devices and features). To insure appropriate coordination with the existing F area
electrical distribution equipment, SRS will need to supply required load-flow, short-circuit, and
intertie relay settings. Ameresco will prepare a transient study if deemed necessary for
design.



Power at the new cogeneration facility is generated at 13.8 kV and is connected to a main 13.8
kV switchgear unit identified as “HVS”. “HVS” is equipped with six (6) breakers. Breaker “52G” is
utilized for the main generator breaker and is complete with required protective and synchronizing
relaying. Breaker “52-4160” feeds a 7500/9375 kilovolt amperes (KVA) transformer “ATX-2” that
steps down to 4160 volts alternating current (VAC) for large motor loads. Breaker “52-480” feeds a
2500/333 KVA

 transformer “ATX-1” that steps down to 480 VAC for all the remaining facility power
distribution loads. Breakers “52-SG-1” and “52-SG-2” are utilized as feeders from two 1500 kW
standby generators. Breaker “52U” is the tie breaker that feeds power to and from the F Area.
This breaker will also be complete with all required protective and synchronizing relaying. The
13.8kV switchgear “HVS” and transformers “ATX1” and “ATX2” are located in the electrical room in
the new cogeneration facility.




D Area Electrical Feeder



A new feeder will be installed in the D Area to provide continued electrical service to both the D
Area and the TNX Area when the 484-D Power Plant is either dismantled or demolished and to reduce
the annual SCE&G costs associated with O&M of Station 41. The new feeder will be a #2 aluminum
conductor, steel reinforced (ACSR) overhead 13.8 KV 3 phase line that will run from the existing
overhead line in the vicinity of Barricade 3 at the entrance to D Area, down the east side of the
entry road to a point roughly 80’ short of the 115 KV line crossing, turn east and run across
country paralleling the 115 KV line just outside of its right of way (ROW) until it is terminated
with a tie-in to an existing 3 phase line crossing at the back of D Area. By connecting to this
line, the new feeder will be able to power the TNX complex without any further modifications to the
existing overhead system. Fused sectionalizing switches will be installed at each end of the new
line. The recloser currently installed back across the Highway on the line being tapped will be
recalibrated to reflect the addition of the line extension to D Area.



Before turning east at the 115 KV line, the new line will cross a CSX railroad main line. A
complete design/permitting package will be developed and submitted to the railroad for their review
and approval. Initial filing fees for this permitting process are included, but any ongoing fees
due CSX are excluded from this proposal and will be the responsibility of the Government.



The addition of this feeder will result in monthly O&M savings currently paid to SCE&G to maintain
the equipment in Station 41. The annual savings is $75,000 (10% reduction of the current O&M
charge to SCE&G).




L Area Capacitor Work



The single 6 megavolt ampere reactive (MVAR) capacitor bank currently sitting on the L Area site
will be installed on a new concrete pad in the grassy area across the access drive on the northwest
side of the switchgear building, and connected to existing breaker 2-6 within substation 151-1L.
New cable and cable tray will be installed in the basement beneath the switchgear to the northwest
wall where spare sleeves will be used to exit the building. A new underground duct bank will be
run from the building wall under the drive to the new pad for the capacitor bank connecting the
capacitor. Spare 4” conduits will also be provided stubbed out from beneath the new pad for future
connections to other systems. The capacitor bank will be interfaced with the existing SRS SCADA
system. The actual location in the grassy area will be coordinated with the proposed installation
of a future grounding transformer. The drive and associated curbs will be replaced after the duct
is installed.

We have been advised that several capacitor cells are defective. These will be replaced with
available spare cells to the extent possible. These are the only repair efforts included in the
installation of this capacitor bank which has been sitting out in the weather unprotected for some
time. Any other repairs necessary to get the bank into fully operational condition are not the
responsibility of Ameresco.



Installation of this existing capacitor bank will assist SRS in maintaining their power factor as
close as possible to the minimum required by the utility company before penalties are assessed.




1.2.4 Proposed Equipment



The proposed ECM 1 will include the major components as described in Section 1.1. An
equipment list and manufacturer’s literature for the boiler and turbine system is included in
Appendix C.




1.2.5 Expected Lifetime



The combustor/boiler and turbine components have an expected lifetime of 25-30 plus years.
Ameresco will repair and replace components to ensure the continuous operation of the equipment
throughout the contract performance period.




1.2.6 Physical Changes to Existing Equipment or Facilities



The cogeneration facility will be located on an unoccupied area of the SRS. The actual site
will not impact or require physical changes to the existing facilities; however, there are changes
required at other areas of the reservation as a result of operations of the new cogeneration
facility.



These include the following:





	 	l	 	 D-Area Electrical Feeder
	 
	 	l	 	 Pump and Controls Replacement in Building 681-3G, Water Pump Station
	 
	 	l	 	 Installation of existing capacitor at the L-Area Substation 151





1.2.7 Savings Proposed



The annual savings associated with ECM 1 are based on the avoided cost of operating and
maintaining the existing D Area Plant. The energy savings result from using a more efficient
boiler and steam distribution system and the energy cost savings from using biomass as the primary
fuel source in place of coal.




1.2.7.1 Annual Project Savings Overview



In order to calculate the annual savings, [**]. Thus, the annual savings from the ECM equals:



Annual Savings = [**].

consumed for the past two years was [**] tons, which is used as the agreed upon
energy savings baseline. The baseline for energy cost is determined by the product of the baseline
energy consumption times the baseline cost of coal. The baseline cost of coal, as provided by SRS
and agreed upon, is $[**] per ton of delivered coal. Thus the baseline energy cost is agreed to be
$[**]. Currently, all electric power required by the site above the net output of the D Area power
plant is procured from SCE&G under Rate Schedule 23 and Rate Schedule 60. The energy charge is
[**] per kWh and the average demand charge is $[**] per kW for load over 20 MW. The baseline power
export from the D Area plant was determined using monthly averages for the last two years of data.
Refer to Table 1.5 for a summary of the fuel consumption and the net power exported from the D Area
plant.

1.2.7.3 Annual Energy Savings Calculations



The annual savings are determined by calculating the baseline annual O&M cost for the existing
plant, plus the annual energy cost as presented in the previous section. The annual savings are
then adjusted to account for the cost to be incurred by SRS to purchase additional power from SCE&G
and to account for the Post-ECM Implementation Costs to be incurred by SRS for the non fuel
utilities of the new cogeneration facility.



The additional future cost of purchased electricity is calculated using the [**]



[**].



The annual savings are also adjusted to account for the Post-ECM Implementation Costs incurred by
SRS to provide non-fuel utilities to the new facility. This includes the cost for river water,
sanitary sewer, and for domestic water. The annual consumption for each of these utilities is
shown in Table 1.6.



The net estimated annual savings for ECM 1 is $33,181,197 for the first year of the performance
period (2012).




1.2.7.4 ECM 1 Performance Measurement



The ECM performance will be measured using the flow output (via a steam flow meter) of the two
biomass boilers. Measuring and totalizing the steam production permits for flexibility to make use
of this steam to meet the thermal and electrical demands of SRS while allowing for normal seasonal
variations and adjustments for expected future load changes. The Annual Steam Guarantee (ASG) for
ECM 1 will be 1,759,485 kilopounds per year (klbs/yr) of steam using an annual fuel consumption of
[**] MBtu/yr and is shown in Table 1.6 — ECM 1 Post-ECM Implementation Facility Performance. The
ASG will remain set throughout the performance period; however, the electrical output and the steam
export output will vary. Annual biomass costs are calculated based on meeting the ASG and will be
adjusted only when the actual steam production for ECM 1 exceeds the ASG; refer to Section 1.3.1.2.



Ameresco proposes to produce additional steam from the cogeneration facility above the ASG, unless
notified otherwise in writing by the contracting officer, provided that the Government compensates
Ameresco for the incremental cost of biomass annually. Additional steam may be used for power
generation or for thermal energy. Excess delivered steam above the ASG will be paid for by the
Government as described in Section 1.3. Further increase in green power generation due to excess
steam production will result in additional annual savings and will be documented in the annual M&V
report.



The planned Post-ECM Implementation Costs for Ameresco to operate and maintain ECM 1 are included
in the performance period expenses set forth on Schedule DO-3. The performance period expenses
include the costs necessary for Ameresco to provide operations and maintenance of the new
cogeneration facility including fuel (biomass and fuel oil for backup), personnel, daily operations
and maintenance, routine and non-routine repair and replacement costs, and operations management to
meet the ASG.

1.2.8 Utility Interruptions



The utility interconnections are described in detail in Section 1.2.3. It is anticipated that
these connections will be made with minimal interruption to the SRS site. Any necessary
interruptions will be coordinated and scheduled in advance with SRS personnel and with M&O site
personnel. The shutdown of the D area plant and the start-up of the new cogeneration facility will
be coordinated with SRS personnel and D Area site personnel to allow for minimal interruptions
during transition.




1.2.9 Agency Support Required



Ameresco will continue to work with the Government as the project moves through the final
design and the construction period. Support from the Government’s engineering, contracting, and
maintenance units, as well as management will be required for continued success of the proposed
project. The Government, through its M&O Contractor Environmental Support Section will be
responsible for processing the storm water management permit, the final site use permit, the
National Environmental Policy Act (NEPA) document, domestic water permit, sanitary sewer permit,
wetland permit, and the new outfall into the site NPDES Permit. Refer to Section 3.2 for a
description of the environmental permit and documentation required for this ECM.




1.2.10 Potential Environmental Impact



Refer to Section 3.0 for environmental benefits and impacts from both ECMs.




1.2.11 ECM Property Ownership



As approved under the BAMF Contract, title to all contractor-installed equipment proposed
under this ECM will vest with the Government upon its acceptance of such ECM or the date that
commercial operations begin, whichever occurs earlier.




1.2.12 ECM Project Schedule



The construction schedule will be developed using Primavera P-6 software and submitted to the

1.3 BAMF Project Components




1.3.1 BAMF Resource



ECMs 1 and 2 will require approximately 322,118 tons of forest residue biomass per year to
meet Ameresco’s ASG and approximately 385,000 tons of forest residue biomass per year to operate at
design capacity. For such calculation of tons, Ameresco used a heating value of 4,300 Btu/lb from
forest residue. Ameresco intends to procure both clean biomass and biomass derived fuel (BDF).
Clean biomass includes forest residues, some urban waste, untreated wood pallets, and residue from
lumber processes. BDF includes urban wood waste and tire derived fuel and will only be used in
connection with ECM 1. There are numerous sources of clean biomass within a 100 mile radius of the
SRS site, including within the SRS Forest. The following sections describe available BAMF supply,
BAMF pricing, and BAMF acquisition.




1.3.1.1 BAMF Supply



Following several discussions with the local office of the U.S. Forest Service and SRS
personnel, Ameresco proposes to assume responsibility for the fuel procurement and intends to meet
the biomass fuel requirements for ECMs 1 and 2 through purchases from local biomass suppliers.
This responsibility shall include the right to validate, verify, and sell any carbon credits, but
not renewable energy certificates, which may be obtainable from the ECMs and their associated
operation and activities. Ameresco will consult with the Government concerning the design,
validation, and verification for carbon offset credits and will make reasonable commercial efforts
to obtain carbon offset credits which may be associated with the ECMs. Those credits may arise
from the substitution of biomass residues for use in lieu of fossil fuels, and the use of biomass
from onsite activities, including those from forest reforestation and working forest activities.




BAMF Deliveries



There will be deliveries of biomass and other BAMF fuel scheduled daily, Monday through Friday
(normal operations), throughout the contract performance period. It is estimated that up to 60
trucks may enter and depart the C and Burma Road location each day, five days per week. It is
anticipated that deliveries will be accepted from 7:00 AM to 7:00 PM although the exact hours may
vary by season and/or supplier. Acceptable delivery hours will be established with each biomass
supplier. Following meetings with SRS personnel, Ameresco has agreed to minimize the number of
deliveries departing the site at the C Road traffic signal from 6:30 to 8:30 AM to accommodate
arriving SRS personnel turning left at that traffic signal. Ameresco has been given assurance, and
this proposal is predicated upon biomass delivery vehicles being permitted to enter and depart the
SRS reservation at any of the available (open) gates and not be limited to just the Aiken and
Jackson Barricades.

Drivers of the BAMF delivery vehicles will be required by Ameresco to obtain a permanent (one year)
site badge and to comply with SRS vehicle safety and site entry requirements, except as noted
above.

1.3.1.3 BAMF Acquisition



Ameresco may enter into an agreement with one or more biomass suppliers. Ameresco will also
attempt to secure from each supplier a fixed fuel price for as long a term as possible.




1.3.2 BAMF Transportation, Metering, & Delivery




1.3.2.1 BAMF Transportation & Delivery



The biomass will be delivered from the suppliers using trucks with live bottom feeders,
self-dumping trucks, or trucks with high-side trailers. Typically, each of the larger trucks has
the capacity to hold approximately 120 cubic yards of fuel per load. The smaller self dumping/end
dump trucks typically only carry about 50 cubic yards of fuel and will be used primarily for BDF
waste sources or for larger unprocessed fuel. Actual loads may vary with the density of the fuel.
Normal truck deliveries will be arranged to be made Monday through Friday.




1.3.2.2 BAMF Metering



Woodwaste is commonly measured in units of weight and volume such as in tons, truck loads, or
cubic yards, rather than in units of energy. For this proposal, the higher heating value of
biomass is about 4,300 Btu/lb since the majority of the fuel will be from forest residues and is
typically high in moisture. The fuel supply will be tracked and recorded using the truck scale
tickets. Periodic testing will be done on the fuel to determine the composition and the heating
value.

1.3.3 BAMF End-Use Project




1.3.3.1 BAMF End-Use Demand



End use of the biomass source was calculated utilizing forest residue as the main fuel source
to meet the ASG. Forest residues for the Carolina area are typically high in moisture with heating
values in the range of 4,100-4,600 Btu/lb. For the design basis and end use demand calculations, a
higher heating value of 4,300 Btu/lb was used to determine boiler feed input. At this heating
value, the boiler efficiency is expected to be 70%. At these conditions, the expected annual fuel
use for ECM 1 is 317,118 tons a year of biomass consisting of forest residues.




1.3.3.2 BAMF End-Use Operations & Maintenance



Ameresco will retain operational and maintenance responsibility for the cogeneration facility
and equipment installed at the cogeneration facility, described in Section 5.2.7.1 of this
proposal.

2.0 ECM 2 DESCRIPTION




2.1 ECM Summary Schedule DO-4



Pricing Schedule DO-4 is included in Section 6.0, Proposal Pricing Information.




2.2 ECM #2:Biomass Heating Plants for K& L Areas




2.2.1 Detailed Description of ECM




2.2.1.1 ECM Summary



ECM 2 includes the installation of biomass heating plants in the K Area and the L Area. These
new heating plants will replace the existing fuel oil-fired boiler plant located in the K Area that
currently serves heating loads in both the K and L Areas. The two existing 30,000 and 60,000 lb/hr
steam boilers are in poor condition and are now vastly oversized for the current load (estimated by
SRS personnel to be approximately 7,000 PPH of steam in each area at design conditions). The
existing 30,000 lb/hr boiler has been utilized as the primary boiler during the most recent years,
due to the large reduction in load from the original design. Currently steam is produced at 150
psig to distribute to the K and L Areas and reduced inside the secure areas for use at 30 psig or
less. By decentralizing the existing plant and providing local boiler systems in both the K and L
Areas, the losses from the existing aboveground 2.5 mile, 6-inch steam line running from the K Area
to the L Area will be eliminated. Additional efficiency gains are made from the right-sizing of
the new heating plants to match existing loads.



The heating plants are each sized to provide a continuous availability for supply of steam to site
end-users in the K and L areas during the typical heating season of December through mid April.
The individual site demand was based on fuel oil consumption data for the past 5 years. The system
is designed using applicable national codes and standards for steam plants and specific site
standards (refer to Appendix D). Previously, conceptual design drawings were submitted to the site
for review prior to issuance of this final proposal; a draft version of the “issued for pricing”
drawings is included in Volume III of this proposal. Finalized “issued for construction” drawings
will be submitted to the government for concurrence throughout the first year of the construction
as major equipment items are ordered and the design drawings are finalized.



Implementation of this project provides utility savings resulting from 1) The elimination of losses
from 2.5 miles of existing steam distribution piping between the K and L Areas; and 2) Improved
operations from properly sized boilers, and the fuel cost differential in switching from fuel oil
to clean biomass. Annual savings are over $1.1 M for this ECM.



This proposal includes the procurement and installation of the new equipment, the support
facilities, all auxiliary systems and controls, and utility tie-ins required to connect the new
heating plants to the K and L Area distribution systems, as well as ongoing O&M and environmental
compliance of both heating plants for the contract duration.

2.2.1.2 ECM Process Description



This ECM includes two major components for each of the proposed heating plants: 1) Biomass
fuel storage system, and 2) combustion/boiler system. Each new heating plant will be installed in
an enclosed building with an adjacent covered shelter to house the wood fuel storage and delivery
equipment. Biomass fuel will be delivered to both heating plants by Ameresco personnel from the
fuel processing yard of the Biomass Cogeneration Facility. The fuel delivered to each of these
heating plants will be clean biomass (refer to Section 1.3). The clean biomass will be used as the
primary fuel source for two new wood waste combustor boilers to supply steam to the K and L Areas.
Each boiler system will be designed to generate 10,500 PPH of saturated steam at 135 psig.




Biomass Fuel Storage System



The fuel storage area consists of the storage system and feeder to the combustion system. The
components of this system are recommended to minimize equipment at each site and to provide maximum
automation to each of the heating plants. Ameresco personnel will employ tractor-trailers to
transfer the biomass fuel from the fuel yard at the cogeneration facility to both the K and L Area
heating plants. The tractor-trailers will be parked in the new fuel storage shelter bays, one at
each heating plant location. Each tractor-trailer is equipped with a walking floor-bed
installation for the automated transfer of fuel to the stationary metering bin at each heating
plant. The metering bin utilizes augers to feed the fuel into the combustion system.



The flow of fuel is controlled by an integrated direct digital control (DDC) system that automates
the flow of fuel from the walking-bed to the metering bin, and from the metering bin to the
combustor, based on input signals (and required safeties) to maintain steam pressure at the output
of the boiler.



Fuel Storage System components for each area (K and L) includes:





	 
	 	l	 	Tractor trailer with walking bed for fuel feed     
	 
	 	l	 	Fuel storage shelter bay     
	 
	 	l	 	Main fuel bin and auger to feed combustor     





Combustion/Boiler System



One combustion/boiler system will be located in each area, in a separate, enclosed bay connected to
the fuel storage shelter bay. The system proposed is manufactured by Hurst Boiler & Welding
Company, Inc., and is designed specifically for the combustion of solid waste fuels to optimize
energy recovery and minimize air emissions. Refer to Appendix C for manufacturer cut sheets.



When there is a demand for steam the biomass is augered from the fuel storage bin into the
combustor, where the biomass begins to burn by the use of three levels of air directed into the
combustion zone. The primary air is forced into the combustion zone from beneath the fuel grates
(on which the fuel rests during combustion). The secondary air is forced through side grates, and
the tertiary air comes through the side

of the cast refractory to keep unburned ash from exiting the unit. The primary combustion zone is
lined with high-insulating value, cast refractory ceramics to minimize radiant heat losses from the
unit exterior.



A similar, secondary ceramic chamber fired at 3,100°F is included between the primary combustion
zone and the boiler to allow for an extended combustion zone. The extended retention time in the
secondary zone ensures the additional combustion of the biomass and reduces emissions. The
appropriate combustion temperature is maintained by adjusting fuel feed, fan speed, and air intake.



Each boiler will be equipped with an auxiliary burner to allow for the firing of fuel oil for full
output capacity of the boiler. Fuel oil will be used for pilot lighting on startup, and as a
back-up emergency fuel source only. Each boiler has the capacity to produce up to 10.5 k-lb/hr of
135 psig steam when the combustion system is operated at full output. Each is a 2,600 sq ft unit,
with 2 pass design and includes standard instrumentation, rear furnace access door, and
air-operated soot blowers. Downstream of each steam boiler, the exhaust gas will go through a
multi cyclone which reduces the particulate matter in the exhaust gas by 70%. The exhaust stacks
will be equipped with appropriate lighting as required for on-site helicopter travel.



Boiler/Combustion System components for each area include:





	 
	 	l	 	Metering Bin Feeder     
	 
	 	l	 	10.5 MBtu/hr combustion unit     
	 
	 	l	 	Full-capacity fuel oil burner     
	 
	 	l	 	Steam heat recovery boiler     
	 
	 	l	 	Multi cyclone     
	 
	 	l	 	SCADA system     
	 
	 	l	 	Automated ash removal system     
	 
	 	l	 	Exhaust stack with aviation lights     
	 
	 	l	 	Boiler auxiliaries     
	 
	 	l	 	Air compressor for L Area     
	 
	 	l	 	Water treatment skid for L Area     
	 
	 	l	 	Fuel Oil Storage     





2.2.1.3 ECM Operation



Ameresco will be responsible for operating and maintaining the heating plant facilities and
equipment throughout the contract term. Both boilers will be operated by Ameresco as needed to
meet the steam demand as more fully described in Section 2.2.7.3.



Both heating plants will be remote monitored via a telephone modem and using the Site PA system
from the control system at the cogeneration facility. Maintenance and inspection of the systems
will be performed by Ameresco operations personnel from the cogeneration facility. Refer to Table
2.1, which

defines the interconnection and utility O&M responsibility for this ECM. Refer to Section 5.2.7.1
for a detailed description of the O&M responsibilities of each party.




2.2.2 Location Affected



The biomass heating plant at the K Area will be constructed in the same vicinity as the
existing plant, behind the two existing 30,000 gallon fuel oil tanks. The existing fence will be
modified to allow for the construction of a new gate which the biomass delivery trucks will use for
accessing the heating plant. A new facility will be constructed to house the biomass heating
plant, while the biomass fuel storage and feeder area will be located under a covered bay attached
to the new heating plant. For the L Area, a replica of the K Area heating plant will be installed
northeast of the abandoned cooling water basin. The footprint for each system is approximately
2,600 square feet, including an enclosed sound proof control booth. Refer to Figure 2.1and Figure
2.2 for site location plans for each area.

2.2.3 ECM 2 Interface with Government Equipment



Title to all Ameresco installed equipment will transfer to the Government at the time of
Government acceptance of an ECM. For the sake of clarity, ECM 2 will interface with existing
Government equipment at the utility interconnections as described in this section. The
installation of utility interconnections required for the new heating plants are included in the
project implementation cost and the installation will be Ameresco’s responsibility; however, the
SRS M&O Contractor will retain O&M responsibility including repair and replacement for the utility
interconnections and utility distribution systems. Table 2.1 provides a summary of the utility
interface and the scope of O&M responsibility for the utility systems. Ameresco and the SRS M&O
Contractor will enter into an agreement that will provide the heating plants with utility services
to include river water, process sewer service, backup electrical power, and domestic water service.
A PSUP form will be completed by Ameresco prior to construction of utility interconnections.
Utility meters will be installed to measure usage. It is proposed the Government will incur the
cost for the cogeneration facility’s non fuel utilities. These Post-ECM Implementation Costs have
been factored into the annual savings. The annual consumption and costs of the utilities are shown
in Table 2.5, and the unit cost used for each utility is shown in Table 4.2. Refer to Section
5.2.7.1 for operation and maintenance responsibility.

Electrical System



K Area: At the time Ameresco performed the initial field survey, SRS staff were beginning the
process of designing a dedicated overhead 300A, 480V feeder and panel board. This system has not
been installed to date, so a new feeder from the 151-2K substation will be provided as part of the
ECM 2 work scope. New motor control center(s) and associated low-voltage distribution equipment,
lighting, and related requirements associated with the new boiler and fuel handling equipment will
be provided.



L Area: Based on information provided by SRS, the switchgear, 183-2L is available for
interconnection and has adequate capacity for the load of the heating plant. Ameresco will run a
new feeder from 183-2L to serve a new overhead wood-pole distribution line to the proposed boiler
plant site. A new feeder will supply the motor control center and distribution panel(s) required
for the new equipment.




Steam Distribution System



K and L Area: Each new boiler will be connected to the existing steam distribution lines within
each area. The new boiler system will operate at 135 psig and pass through the existing PRV
station for distribution to end users at 30 psig.




Boiler Feedwater



K Area: Existing boiler feedwater services will be utilized for the new heating plant. Ameresco
will use and maintain the existing water treatment system. If the existing well water treatment
plant is not upgraded to produce domestic water prior to project startup, a small water tank will
be installed to hold domestic water for use in the safety shower and eye wash station.



L Area: River water will be used as the source for boiler feedwater for the heating plant. There
will also be a domestic water feeder used as a backup source for boiler feedwater and to feed the
safety shower and eyewash. A new water treatment facility will be installed to treat the water for
suitability of the new biomass boiler.




Process Sewer



K Area: The boiler blow down will connect to the process sewer system that runs to the existing
ash basin.

L Area: The boiler blow down will be discharged to the existing L-07 Outfall. Ameresco will be
responsible for ensuring this (L Area heating plant) effluent is compliant with the NPDES Site
Permit.




2.2.4 Proposed Equipment



The proposed equipment is described in the previous section and an equipment list and
manufacturer information for the combustor/boiler system is included in Appendix C.




2.2.5 Expected Lifetime



The major equipment components have an expected lifetime of 20 — 30 years. Annualized repair
and replacement costs have been included in this proposal. Ameresco will be responsible for all
repair and replacement required to maintain heating plant operation.




2.2.6 Physical Changes to Existing Equipment or Facilities



Both proposed heating plants will be located outside of the process areas; however, this ECM
proposes to make the following modifications within the K Area:





	 	l	 	The K Area water treatment building will be left in place and existing water
treatment components will be utilized. Ameresco will maintain the water treatment equipment
and building throughout the term of this contract.
	 
	 	l	 	The air compressor located next to the existing fuel boilers in the K Area will
be used for the new biomass combustor system. Ameresco will maintain the air compressor
throughout the contract term.





2.2.7 Savings Proposed



The annual savings associated with this ECM are based on the avoided cost of operating and
maintaining the existing K Area Plant including the distribution system between the K and L Area,
the annual energy savings resulting from using a more efficient boiler, and by using biomass
instead of fuel oil as the primary fuel source. Additional energy consumption savings will be
realized by replacing the K Area plant with two smaller heating plants, which eliminates the 2.5
mile distribution line between the two areas.



Table 2.2 summarizes the annual savings associated with ECM 2. Annual Energy Savings [**]. Annual
Energy Savings and O&M Cost Savings shown on Table 2.2 are herein agreed to by the Government and
Ameresco for the term of the contract.

2.2.7.1 Annual Energy Savings



The annual savings are based on the avoided cost to operate and maintain the K Area plant
including the distribution system between the K and L Area and the cost of energy required to
produce steam in the existing boilers minus the Post ECM cost of the non fuel utilities for each
heating plant. The savings will be applied to fund the capital cost of the project and to fund the
ongoing performance period expenses throughout the contract performance period term. The
performance period expenses include the costs to operate and maintain the new heating plants such
as biomass and fuel oil cost, labor cost, consumable costs, maintenance costs, repair and
replacement cost, and operation management. The following subsections show the baseline cost and
energy consumption for the existing K Area Plant, the calculations of fuel and operating costs of
the new heating plants, and the savings summary for the proposed project.




2.2.7.2 Annual Energy Baseline Consumption & Costs



Currently the K Area plant utilizes one 60,000 lb/hr fuel oil boiler and one 30,000 lb/hr fuel
oil boiler to serve both the K Area and the L Area facilities via a 2.5 mile steam pipeline. Data
provided by SRS indicates that the 30,000 lb/hr boiler is the primary boiler, with the 60,000 lb/hr
not having run in the past 3 years. Steam is produced at 150 psig and is reduced to an operating
pressure of 30 psig for each site. The existing boilers are oversized and past their useful life,
and are currently a costly maintenance issue.



In order to calculate the annual savings for this ECM, a baseline was developed to depict the most
reasonable representation of the annual energy determined by taking the average consumption of the
past 5 years, and to determine the annual O&M costs which were based the average of the past 5
years as shown in the following tables:

Using the past 5 years of data for fuel oil consumption, the annual average consumption is
309,631 gallons. The current price of fuel oil is $2.13 per gallon; therefore, the baseline energy
cost is $659,514.



The annual savings for ECM 2 are equal to the O&M cost savings plus the annual energy costs
baseline minus the post-ECM non-fuel energy costs. The annual savings for ECM 2 is $1,188,383 for
the current year and $1,171,260 for Year 1 (2012).




2.2.7.3 Annual Heating Plant Performance



For ECM 2, heating plant performance is based on heating plant availability to provide steam
to the K and L Areas, with outages no longer than a period of a week (seven continuous days) at any
one time, during the typical heating season of December through April up to a maximum of 33,300
klbs/yr (Availability Guarantee). The annual fuel cost for this ECM has been calculated using an
annual steam production of 33,300 klbs. If the steam load for the heating season is lower than
33,300 klbs and therefore the fuel consumption is lower, the difference will be reconciled as
described in Section 1.3. It is expected there will be a reduction of 10% of the steam load due to
the shutdown of the steam line between the two areas. If the steam production is higher due to an
increase in either Area’s demand, the fuel cost will be adjusted annually. Annual fuel costs are
calculated based on meeting the Availability Guarantee and will be adjusted annually on actual
steam production and actual fuel consumption (Refer to Section 1.3). The expected heating plant
performance is shown in the following table:

The non-fuel utilities consumed at each of the heating plants are to be incurred by the
Government. The Post-ECM implementation cost has been deducted from the annual savings for each
year of the performance period. The water consumption is based on the Availability Guarantee and
the electricity consumption is based on the load of the heating plants for the typical heating
season. The annual utility cost was calculated by multiplying the consumption by the unit cost of
the utility (refer to Table. 4.2). The unit cost of the utilities is escalated using the NIST
values and the [**]% escalation for the water cost.

The utility interconnections are described in detail in Section 2.2.3. It is anticipated that
these connections will be made with minimal interruption to SRS functions. Any necessary
interruption will be coordinated and scheduled in advance with site personnel.




2.2.9 Agency Support Required



Ameresco will continue to work with the Government as the project moves through the final
design and the construction period. Support from the Government’s engineering, contracting, and
maintenance units, as well as management will be required for continued success of the proposed
project.

3.0 ENVIRONMENTAL IMPACT OVERVIEW



By utilizing on and off site biomass sources (rather than coal and fuel oil) to produce steam
and energy, the proposed ECMs will provide a positive impact the environment. However, since both
ECMs introduce new equipment and structures onto the site/area, assessments and permits are
necessary in order to comply with the applicable local, state, and federal requirements. The
positive impacts and benefits of the project are highlighted in Section 3.1. Section 3.2 describes
the environmental permitting required by the SCDHEC and other required environmental documents.



3.1 Overview of Environmental Benefits





	 	l	 	The proposed plants will decrease the overall air emissions rates for 1)
particulate matter (PM) by more than 400 tons a year, 2) nitrogen oxides (NOx) by more than
2,500 tons a year, and 3) Sulfur Dioxide (SOx) by more than 3,500 tons a year. This will
result in a positive impact to the air quality of the local area.
	 
	 	l	 	Both ECMs will reduce energy consumption by eliminating over 6 miles of steam
distribution lines (3.5 miles for ECM 1 and 2.5 miles for ECM 2). The reduced steam
distribution pipe will decrease fuel consumption by at least 10% from reduction of in-line
steam losses.
	 
	 	l	 	The proposed cogeneration facility will decrease the amount of river water
currently drawn from the Savannah River by over 1,412,000 kgal per year. This is
especially significant as the level of the Savannah River is low and this project will
support efforts to protect the water level.
	 
	 	l 	 	 By replacing fossil fuels with a renewable energy fuel source, green house gas
emissions will be reduced by at least 100,000 tons a year significantly decreasing the
carbon footprint of the SRS.
	 
	 	l	 	 Although cogeneration facility and heating plants are not practical feasible
buildings for Leadership in Energy and Environmental Design (LEED) certifications, both
ECMs will incorporate sustainable design methods and incorporate energy efficient
technologies into the design.





3.2 Overview of Environmental Permitting &
Assessment


Since the proposed projects will be located at a new site and/or require the installation of
new equipment there will be new emission sources for air, water, and waste water. The resulting
emissions require environmental permits through the Environmental Protection Agency (EPA), SCDHEC,
and SRS. The following table is a summary of the permits required for the project, the status of
the permit, and the expected issuance of the permit. Each of these is further described in the
paragraphs below. The schedule and proposal are based on the dates in the table; significant
deviation of these dates could potentially delay construction. Ameresco will have responsibility
for maintaining compliance with the permits through the construction period and the contract
performance period.

Construction & Operating Air Permit


The equipment in both ECMs are permitted under one new construction air permit and will be under
the Ameresco permit rather than site permit. Ameresco will be responsible for the air permit and
for future air permit renewals throughout the contract term. The following table shows the
potential air emissions

of the proposed facility for the criteria air pollutants at expected load and at plant capacity.
Annual potential air emissions are typically calculated based on the potential to emit, which is
defined as the emissions for continuous operation at maximum system capacity. The maximum capacity
would be if the boilers are operated at the full load of 120,000 lbs/hr for 8,760 hours. The
controlled emission rates are based on vendor supplied data for the technology proposed in previous
section.

NPDES Permit


The proposed outfall for ECM 1 will be included as part of the SRS NPDES Permit. The modification
to site permit was submitted to the site for approval this past month; it is expected to be
incorporated into the Site permit by March 2009. For ECM 2, the K Area boiler blowdown will
discharge into the K Area Ash Basin, as opposed to being discharged to an NPDES outfall. The NPDES
outfall L-07 was modified to include boiler blowdown discharges for the L Area Biomass Heating
Plant. As part of the Memorandum of Understanding/Memorandum of Agreement (MOU/MOA) between
Ameresco and M&O Contractor, language will be incorporated to require Ameresco to retain
responsibility for compliance of the cogeneration facility outfall and for the K and L Area heating
plant effluents.

Storm Water Management Permit


The storm water management prevention plan is currently being developed. Once this plan is
submitted, the permit application will be submitted to the M&O Contractor staff for approval. It
is expected it will be approved within 30 days of submittal.



NEPA


Under the National Environmental Policy Act (NEPA), any modification to a federal facility or site
requires determination of the environmental impact of the proposed change or new process. This
requires issuance of a CATEX (categorical exclusion), development of an environmental assessment
(EA) to determine finding of no significant impact (FONSI), or development of an environmental
impact statement. During the DES phase, the EA was developed to include both proposed ECMs. The
document has been placed for public review. The FONSI was issued in July of 2008.

4.0 ECM PERFORMANCE MEASUREMENT




4.1 Overview of Proposed Annual Savings



Implementation of the proposed ECMs will result in an estimated annual savings of
approximately $34 million. Savings estimates are detailed in DO Schedule 4 in Section 6.0.




4.2 M&V Plan Executive Summary



Measurement and Verification (M&V) options include A, B, C, and D as detailed in M&V
Guidelines of the International Performance Measurement and Verification Protocol (IPMVP).

for Federal Energy Projects, Version 2.2; and International Performance Measurement & Verification
Protocol (IPMVP), Volume I, March 2002, available at
www.eere.energy.gov/femp/financing/superespcs_mvresources.cfm.




Annually, Ameresco will complete an M&V report for the project following a visit to the site
and an analysis of system performance. During the annual site visit, Ameresco staff will collect
the monthly performance/operational data, determine the actual fuel use and costs, and then provide
report of the output of each of the sites. Further, monthly reports will be made available to SRS
which include total steam production from each system and fuel usage. Monthly reports will also
include electrical production parameters in addition to steam.



As stated in the individual ECM description sections, annual savings will be based on the avoided
baseline energy and operations and maintenance costs for the existing plants. Therefore, the
annual savings amount is pre-determined for each year of the contract term and will only change
with annual escalation or a mutually agreed upon baseline adjustment, as the existing plants will
no longer operate once the new biomass plants become operational. The annual avoided baseline
energy and operations and

maintenance costs for the existing plants are deemed to have been met upon acceptance of the ECMs
by the Government.



Annual performance requirements are satisfied if, for ECM 1 the ASG is met, and if for ECM 2 each
of the heating plants is operated during the heating season as required to meet the Availability
Guarantee.



If Ameresco is able to produce more steam than the ASG in any given year from the cogeneration
plant, the Government may receive such additional steam for power generation or for thermal use.
If the Government requires and Ameresco is able to produce more than 33,300 klbs in any given year
from the total of both the K and L Area heating plants, the Government may receive such excess
steam for additional thermal use. To the extent the actual steam production exceeds the ASG, the
Government will compensate Ameresco for the additional fuel consumption as proposed pursuant to
Section 1.3.1.2.




4.3 Whole Project Data / Global Assumptions




4.3.1 Risk and Responsibility



Ameresco will be responsible for project construction including the installation, testing, and
commissioning of the equipment to deliver a complete and usable facility. Subsequent to
construction, Ameresco will be responsible for ongoing operations and maintenance of the equipment
installed under ECM 1 and ECM 2. Additionally, Ameresco will provide annual M&V reconciliation
services and an annual M&V report which will include documentation of infrastructure and material
condition, and a summary of equipment performance for the previous performance period.



The risk and responsibility of the Measurement and Verification activities for this project are
addressed in the Risk/Responsibility Matrix in Section 5.4 of this proposal.




4.3.2 Energy, Water, and Operations and Maintenance (O&M) Rate Data



Utility Rates


The energy costs (rates) used to develop the baseline annual cost for ECMs 1 and 2 were provided by
SRS based on historical costs. Annual savings were calculated using the current unit cost and for
coal and fuel oil and the baseline consumption data as described in Sections 1.2.7 and 2.2.7.
Post-ECM implementation non fuel utility costs required for operation of the cogeneration facility
and of the heating plants were factored into the savings at the following previously agreed upon
unit costs as shown in the following table:

Performance Period Rate Adjustment Factors


For both ECMs, the annual energy rates used for savings calculations were adjusted using the latest
escalation factors available from the 2008 National Institute of Standards & Technology (NIST).
The applicable NIST escalation rates are shown in Table 4.3 below. O&M cost savings and the
performance period O&M cost use an annual escalation factor of 3%.

to the Government a post-installation report, and thereafter, an annual M&V report documenting
equipment performance. Ameresco will follow the Federal Energy Management Program (FEMP)
guidelines in generating these reports. The post-installation report will be submitted to the
Government within 60 days following notification of an ECM’s substantial completion and beneficial
use as given by

Ameresco. The performance period report will be submitted each year within 120 days following the
anniversary date of the ECMs substantial completion date.




4.3.4 Status of Utility Company Incentives



There are no known incentives through the utility company for any of the ECMs in this proposal.




4.4 ECM-Specific M&V Plan and Savings Calculation Methods




4.4.1 Overview of ECM Specific M&V Plans



A specific M&V plan based on DOE FEMP Guidelines and the IPMVP for Measurement and
Verification activities during the term of the contract is described for both ECMs in the following
paragraphs.




4.4.1.1 ECM 1: Biomass Cogeneration Facility



M&V Overview


Option B — ECM Isolation will be used for verification of the performance of ECM 1. Option B
focuses [**].




4.4.1.2 ECM 2: Biomass Heating Plants for K& L Areas



M&V Overview


Option B will be used for [**] to the K and L Areas.




4.4.2 Energy and Water Baseline Development



Refer to the summaries of savings calculations in Sections 1.7 and 2.7 of this proposal.




4.4.3 Proposed Energy & Water Savings Calculations and Methodology



Refer to the summaries of savings calculation in Sections 1.7 and 2.7 of this proposal.




4.4.4 Operations and Maintenance Cost Savings



The K Area plant is operated by SRS personnel and the D Area plant operations are
subcontracted by the M&O Contractor to a subsidiary company. Both ECMs will result in the shutdown
of an existing plant and eliminate the operation and maintenance expenses required for these sites.
Therefore, SRS will realize an annual savings of $ [**] of O&M costs for ECM 1 and $[**]
of O&M costs for ECM 2 during the first year of the contract performance period. The O&M cost
savings have been escalated at a previously agreed upon rate of [**]% per year the contract term.

5.0 MANAGEMENT APPROACH




5.1 Integrated Management Review Team (IMRT)



Ameresco’s Initial Proposal recommended establishing an Integrated Management Review Team
(IMRT) made up of senior managers from both the Government and Ameresco. While there have been
frequent meetings, conference calls, and project reviews, it is strongly recommended that the IMRT
be activated (in some form) immediately following contract award. As we progress with finalizing
the engineering details and begin mobilizing for construction, the IMRT will be a valuable asset
for promptly resolving any serious challenges that may arise and ensuring that SRS executive level
managers are fully cognizant of project status at all times. It is further recommended the IMRT be
chaired by the Director of the Infrastructure Support & Oversight Division or his designee. The
primary mission of the IMRT will be to assure that appropriate management personnel from each
organization are aware of the project status, informed of key milestones, and if necessary,
involved in securing project approvals.



It is recommended that IMRT membership consists of key personnel from each of the four
organizations participating in the project — DOE SRS, DOE Headquarters, the site M&O contractor
staff, and Ameresco. A proposed IMRT organizational chart, designating team member organizations,
is included as Figure 5.1. The IMRT should be established immediately and convene at least
quarterly throughout the implementation and operations phases to assure senior management is
informed, issues resolved, and decisions are rendered timely.

5.2 Ameresco Management Approach



Ameresco will be responsible for the design, construction, and operation of both ECMs as
included in this proposal. This includes the responsibility for the management of design, quality
control, safety, construction, and operation. Ameresco’s management approach is outlined into
following sections and includes the key strategies listed below:





	 	l
	 	 Design in accordance with applicable industry codes and design standards for industrial
heating plants and power plants (Refer to Appendix D for list of standards) and in
accordance with the electrical standards, fire protection standards and stacking lighting
standards provided by Government.
	 
	 	l
	 	 Design documents will be issued to the Government for review and final concurrence
intermittently throughout the first year of the construction period.
	 
	 	l
	 	 Acceptance of changes to the approved design requested by the government is at the
discretion of Ameresco.

	 	Contract DE-AM36-02NT41457







	 	l
	 	 Ameresco is the responsible authority for the job sites of the proposed ECMs. This
includes authority for site management, safety enforcement, document control, quality
control, receipt and acceptance of project deliveries, and construction procurement.
	 
	 	l
	 	 Ameresco will be responsible for document control management including review and
approval of all construction submittals. Ameresco will make electronic copies of major
construction submittals available to government representatives upon request.




Project Implementation Phase (Construction)


Ameresco’s approach to managing the implementation (construction phase) of the proposed measures
will be to assign a fully competent management staff at the construction site and give them the
resources and authority to complete our contract obligations safely, timely, and in a professional
manner. Each member of the on-site management team, headed by the Site Manager, will have the
authority to make project decisions commensurate with their position. Key members of the site
project management team include the Site Manager who will also be the Senior Construction Manager,
Project Construction Manager (engineering subcontractor representative), Job Superintendent, Site
Safety Manager, and Project Documentation Manager. We are currently recruiting, interviewing, and
identifying personnel for most site management positions. However, the Site Safety Manager was
identified early in the DES phase and has been involved with the project for some time. Mr.
Clinton Sandmel will manage the safety program during the construction phase and has interacted
with the SRS Safety Office in completing the project safety analyses and plans, as well as
overseeing the safety efforts of the geotechnical subcontractor. He is an experienced safety
manager and also has experience managing construction safety programs at DOE installations. Mr.
Sandmel and other members of the project management team will be relocated (if not already in the
local area) to the Aiken/Augusta area for the 30 month construction period mitigating travel and
per diem expenses.



Construction subcontractors are being recruited and interviewed from the local area as well as on a
regional and national basis. Ameresco will attempt to maximize the use of local contractor firms
in an effort to support the local economy and mitigate mobilization and travel costs associated
with using subcontractors from outside the local area. Of course, the construction subcontractors
will be key to successful project implementation, and qualifications and price are both
considerations in subcontractor selection. Each subcontractor will provide a project foreman and
safety and quality control personnel. A detailed plan for completing the implementation phase is
included in Section 5.2.6 below.



The site project team will have all the resources necessary to ensure project success available,
including the support of corporate resources from anywhere within the Ameresco organization from
anywhere in North America beginning with the Ameresco corporate staff. While most construction and
project administration activities will be accomplished by the onsite staff, contract
administration, accounting, subcontract administration, and project legal counsel will be
self-performed by division or corporate staff. Technical oversight of engineering, construction
management, and safety will also be accomplished by the corporate resources.

	 	Contract DE-AM36-02NT41457





Operations Phase (Contract Performance Period Services)


Once construction is complete and the Government accepts the project as operational and the
Contract Performance Period begins, the Ameresco staff will shift from implementation to operations
using primarily an onsite staff of Ameresco managers, technicians, and support personnel
supplemented as
necessary by subcontractors and other personnel from within Ameresco’s corporate resources. The
cogeneration facility will operate, and be staffed, 24 hours a days, 7 days a week, 365 days a year
while the K and L Area plants, although not staffed, will operate 24 hours a day, 7 days a week
during the winter heating season.



The Site Operations Manager will lead all facets of ECM operations. This person has not been
determined at this time; however, it is anticipated they will be in place (at the project location)
well before testing and commissioning begins. Key members of the operations staff will be the
Plant Manager, Safety/Environmental Manager, Fuel Procurement Manager, and the Office Manager.
Although we continue to recruit, and have interested candidates, none of the operations staff
managers have been identified at this time. Also, maintenance personnel and plant operators
currently working at the D Area plant will be given an opportunity to join the Ameresco team at the
new cogeneration facility. All site operations and maintenance personnel will reside in the local
community eliminating travel and per diem expenses. Detailed plans for operating the cogeneration
facility and heating plants are included in Section 5.2.7 below.



To the maximum extent practical, project implementation and subsequent plant operations will be
performed under the watchful eye of the skilled and experienced leadership of the onsite management
team; however, the onsite project team will have the full support and backing of additional
corporate resources as necessary.




5.2.1 Ameresco Corporate Management Team



Ameresco’s corporate management team from the ESCO Selection Interview, Initial Proposal, and
Detailed Energy Survey remains intact and will continue to direct, facilitate, and coordinate
Ameresco’s activities into the construction and subsequent operational phase of the biomass ESPC.
Safety and Risk Management have already been added to the corporate team and other additions,
including the Site Manager and Site Operations Manager, will be added at the appropriate time. Mr.
Keith Derrington, Vice President and General Manager will continue as the senior corporate
executive ultimately responsible for assuring success of Ameresco’s Savannah River activities.



An organizational chart depicting the composition of the Ameresco project team is included as
Figure 5.2.

5.2.2 Program Manager



Mr. Joe Price will continue as Program Manager, although much of the interaction and interface
that he previously facilitated with the DOE and M&O staffs will be transferred to the Site Manager
during construction and ultimately to the Site Operations Manager once the ECMs become operational.
Mr. Price reports to Mr. Derrington and has overall responsibility for Ameresco’s contract
performance and client relationships at SRS. The Program Manager will also lead Ameresco’s
representation to the IMRT, most likely through the implementation phase before passing that
responsibility to the permanent Site Operations Manager, although no decision has been made on that
at this time.




5.2.3 Engineering



Ms. Nicole Bulgarino will continue as Ameresco’s Lead Project Engineer for the cogeneration
facility and the heating plants and will represent the engineering and environmental activities at
the IMRT.
Ms. Bulgarino is responsible for project engineering and design, as well as the subsequent
construction and performance period services. Responsibility for performance period services
including equipment performance issues and annual M&V activities will also fall under purview of
the Engineering Team but will be accomplished by the site operations staff.




5.2.4 Business Operations



Mr. James Koulovatos, Ameresco’s Director of Finance, leads the offices within the business
operations group. Responsibilities of those offices to support the cogeneration facility and
heating plant projects include accounting, contracting, financing, etc. Pending contract award,
Mr. Koulovatos’ staff will manage the development of competitive financing bid packages, work with
3rd party lenders to secure financing for the program, and prepare the final DO
Schedules and Termination Liability Schedule once financing is secured and the interest rate is
locked. Contractual activities include day to day contract administration functions and accounting
will maintain invoicing and accounts receivables ledgers.




5.2.5 Safety and Risk Management



Mr. Kenneth Gross, Ameresco’s Director of Safety and Risk Management, has overall
responsibility for the company’s safety program. Site or project safety personnel will report
directly to Mr. Gross who has been involved with the development of the Worker Health and Safety
Plan (WSHP) to ensure compliance with 10 CRF 851 requirements.




5.2.5.1 Site Safety Management



The Site Safety Manager (SSM) will report to the Director of Safety & Risk Management and is
charged with ensuring the safety of the entire job site. The SSM, Mr. Clinton Sandmel,
participated in development of the WSHP and the associated Job Hazard Analyses (JHA). The SSM is
charged with ensuring that contractor and subcontractor personnel compliance with all applicable
safety regulations. In carrying out site safety duties, the SSM will conduct safety (toolbox)
meetings and inspections and complete the required periodic reports. The SSM will immediately
report unsafe conditions and safety

incidents to the DOE Facility Representatives and the Ameresco Site Manager, Director of Safety and
Risk Management, and the SRS Program Manager.




5.2.6 Construction



As Director of Construction, Mr. Bo Harkness oversees all construction activities within the
federal business unit. The Site Manager, who reports to Mr. Harkness, will be charged with the
day-to-day site management responsibilities during the project implementation phase. Mr. Harkness
will work hand-in-hand with the Program Manager and Lead Engineer to ensure quality construction
completed on schedule and on budget. The Site Manager will also be the on-site point of contact
for SRS/ M&O personnel during the construction phase.




5.2.6.1 Subcontract Management



Onsite construction work will be subcontracted to companies from all parts of the country.
The Director of Construction and Subcontract Administrator will manage all subcontracts, while the
project Site Manager and project Job Superintendent will execute and oversee the subcontracts,
having authority to schedule, inspect, and accept subcontractor work. The Subcontract
Administrator or Director of Construction will respond to any financial or contract management
issues. Invoicing and payments to subcontractors will be handled through standard accounting
procedures and using American Institute of Architects (AIA) contract formats and forms.




5.2.6.2 Construction Management



The Site Manager will be charged with the day-to-day site management responsibilities during
the project construction phase and is tasked with overall responsibility for job site activities.
The Site Manager will also be the on-site point of contact for DOE Facility Representatives and
other SRS/ M&O personnel during the construction phase. Assisted by other Construction Managers
and Job Superintendent personnel, the Site Manager will lead all aspects of project construction
including scheduling, coordination, construction, commissioning, and contract closeout with the
strictest adherence to safety, quality, and cost control procedures.



Project Quality Control (QC) is the responsibility of everyone involved in project activities;
however, ultimate responsibility for the Ameresco QC program rests with the Director of
Construction. Those responsibilities are delegated to the site Quality Control Manager (QCM) who
is tasked to oversee project specific QC activities. The Site Manager or Job Superintendent may be
delegated as the site QCM overseeing the QC activities of all QC personnel, Ameresco and
subcontractors, or a dedicated QCM may be assigned to the project team reporting to the Site
Manager or Job Superintendent.



The site QCM is responsible for individual project quality control. The QCM maintains the Project
Submittal, Testing, and Inspection Logs. The QCM will ensure that project documents (submittals,
shop drawings, reports, etc.) are complete, accurate, and processed in a timely manner. The QCM is
also charged with ensuring testing and inspections are conducted properly and in a manner that will
insure

accuracy. If necessary, the QCM will contract with specialty/professional testing companies (i.e.
concrete tests and welding x-rays).



Ameresco employs the standard Army Corp of Engineers three-phase quality control process that
includes the preparatory phase, initial phase, and follow-up phase. The preparatory phase is
performed prior to each definable work feature. Actions such as reviewing the drawings and
specifications, checking submittal status, and examining the work area, including a hazard
analysis, are done at this time. The initial phase is performed at the beginning of each definable
work feature. Preliminary work is inspected to insure compliance with the contract, establish the
level of workmanship, and ensure compliance with the safety plan. The follow-up phase is ongoing
during performance of work to ensure compliance with contract requirements, perform testing, and
ensure correction of deficiencies.




5.2.7 Site Operations



Once the ECMs are accepted by the government the project will transition to the site
operations phases, which will continue for the remainder of the delivery order performance term.
It is anticipated the cogeneration facility will be staffed with 20 people whose scope of
responsibilities will include the Biomass Cogeneration Facility and the K and L Area heating
plants.



Ameresco intends to have a Site Operations Manager that will oversee the total operation from fuel
procurement and delivery to plant operations and maintenance. The Site Operations Manager has not
yet been identified; however, we have already received inquiries and resumes from interested
parties.



Ameresco will use reasonable diligence to provide a regular and uninterrupted supply of steam (100%
reliability) to the government-owned distribution systems, but shall not be liable for any damages,
losses, costs, or expenses to the government for failure, suspension, diminution, or other
variations of service occasioned by or in consequence of any cause beyond the control of Ameresco,
including but not limited to acts or omissions of the Government and its agents and contractors,
force majeure conditions e.g. acts of the public enemy, acts of God, fires, floods, earthquakes,
etc., or failure or breakdown of the Government-owned distribution system or end-user facilities.




5.2.7.1 Operations and Maintenance Responsibilities

Maintenance Overview



Ameresco will perform the following:





	 	l	 	 Operations including materials and consumables for the cogeneration facility
and heating plants, such as costs for the chemicals, urea, diesel fuel, fuel oil, turbine
filter, lube oil, and ash disposal.
	 
	 	l	 	 Preventive maintenance includes change out of parts, boiler inspection,
boiler cleaning, turbine oil/filter changes, DA tank inspection, pump servicing, grinder
and hogger inspection, instrumentation calibration, engine testing, HVAC servicing,
building upkeep, Old Burma Road repair, and other service as recommended by equipment
suppliers.
	 
	 	l	 	 Unscheduled maintenance includes cost for service and repair not planned on as
part of ongoing maintenance. This mainly consists of contracted service support.





5.2.7.2 Repair & Replacement Responsibilities



The repair and replacement annual expense includes the annual costs expected for the
replacement of materials such as grinder teeth, baghouse filters, sand (bed material) for both
boilers, spare part inventory, and limestone replacement for SOx reduction. These costs will occur
every year regardless of the age of the plant. The repair and replacement costs also include costs
expected to occur for ongoing replacement and repair of boiler in bed tubes, turbine parts, motor
bearings, conveyor belts, and general plant repair fund.



Repair and replacement of the equipment and systems for both ECMs as defined above includes
budgeting and funding an inventory of spare parts, as well as funding and completing minor and
major repairs and equipment replacements. Major repairs and replacements include boiler tubes,
turbine seals, combustor refractory, combustion fans, feedwater pumps, grinders, and augers.
Examples of minor replacements include minor components such as thermocouples, grinder cutters,
instrumentation, motors, motor bearings, filters, chains, and auger components, etc.



5.3 ECM Training



An ongoing O&M Training and Safety Program will be a necessity and training will be provided
to the personnel working at the three sites on a scheduled and recurring basis. Maintaining
training and certification current and in good standing will be required of all personnel. The
training program will also include training with suppliers to ensure the operators are familiar
with the equipment operation and maintenance requirements.

5.4 Risk/Responsibility Matrix



The following pages contain the ESPC Contract Risk/Responsibility Matrix.




RISK/RESPONSIBILITY MATRIX







	 	 	 	 	 
	RESPONSIBILITY/DESCRIPTION	 	AMERESCO’S PROPOSED APPROACH	 	DOE-SR ASSESSMENT
	1.    FINANCIAL:

	 	 	 	 
	 
	 	 	 	 
	a.    Interest rates: Neither
the Contractor nor the agency
has significant control over
prevailing interest rates.
During all phases of the
project, interest rates will
change with market conditions.
Higher interest rates will
increase project cost,
financing/project term, or
both. The timing of the
Contract award may impact the
available interest rate and
project cost.


	 	Ameresco has included preliminary
interest rate information in
Schedule DO-3. The interest rate
shown is indicative of the
financial market at the time of
this Revised Final Proposal and is
provided for information purposes
only.


Once locked with Ameresco’s lender,
the interest rate will remain fixed
for the term of the contract,
thereby providing the DOE-SR with
protection against increased
interest charges resulting from a
variable rate.
	 	In 6.10 of the
Revised Final
Proposal, the
DOE-SR agrees,
among other things,
to not withhold,
reduce, or setoff
the “TOTAL DEBT
SERVICE” amount on
Schedule DO-3 in
the event of an
Ameresco default.
The reason for this
is to provide
assurance to
Ameresco’s lender
that its investment
is secure.


The DOE-SR expects
the Ameresco to
obtain the lowest
possible interest
rate and will
competitively seek
financing from
several financial
institutions. The
DOE-SR expects, as
consideration for
6.10, that Ameresco
will obtain a lower
interest rate than
the one indicated
in the Final
Proposal, dated
December 8, 2008.
	 
	 	 	 	 
	b.    Energy prices: Neither the
Contractor nor the agency has
significant control over
actual energy prices. For
calculating savings, the value
of the saved energy may either
be constant, change at a fixed
inflation rate, or float with
market conditions. If the
value changes with the market,
falling energy prices place
the Contractor at risk of
failing to meet cost savings
guarantees. If energy prices
rise, there is a small risk to
the agency that energy


	 	The D Area plant that is being
replaced by the Biomass
Cogeneration Facility is fueled by
coal purchased from SCE&G.
Ameresco proposes to establish the
pre-installation baseline for ECMs
1 and 2 based on the consumption
and cost information provided by
SRS and M&O Ameresco personnel.
The baseline costs are escalated at
2008 published NIST rates for each
year of the performance period.


The energy savings for all ECMs are
calculated based
	 	The rates used to
establish the
energy baseline are
different than what
has been included
in DOE HQ’s
database, Energy
Management System
4. Based on the
unprecedented
increases in coal
costs over the
previous year, the
baseline costs
associated with
coal will come from
SRS’s current
one-year coal
contract for the
D-Area Powerhouse,
which took effect on

	RESPONSIBILITY/DESCRIPTION	 	AMERESCO’S PROPOSED APPROACH	 	DOE-SR ASSESSMENT
	       saving
goals might not be met while
the financial goals are. If
the value of saved energy is
fixed (either constant or
escalated), the agency risks
making payments in excess of
actual energy cost savings.
Clarify how future energy
costs will be treated.


	 	on the reduced fuel costs associated
with improved
system efficiencies. To determine
this reduction, the following items
are predetermined for establishing
the pre-installation baseline: the
unit cost of fuel oil and coal, and
the amount of energy produced by
the existing D Area and K Area
plants.


The pre-installation baseline data
used in this proposal consists of
cost and consumption data for a 24
month period as provided by SRS and
M&O personnel for ECM 1, and 5
years of data was used to develop
the baseline for ECM 2. The future
cost of each of these utilities has
been escalated by the applicable
NIST factors for each year
throughout the contract term.


Ameresco proposes the DOE-SR assume
responsibility for the actual unit
cost of utilities (i.e.
electricity, coal, water, etc.)
including any escalation or
de-escalation. If at any time
during the term of this contract,
the ECMs do not create sufficient
savings on an annual basis to fund
the amount due Ameresco for reasons
within SRS’ control or for reasons
related to changes in unit price of
utilities, then SRS will pay
Ameresco as agreed or renegotiate
the payment schedule and term in a
form mutually agreeable to both
parties and Ameresco’s lender such
that the outstanding balance of
contract payments is fully repaid.


Ameresco proposes to assume
responsibility for biomass
procurement and has estimated the
price of biomass based on current
local market conditions escalated
at [**]% per year.
	 	November 1,
2008. Based on
market research,
coal is not
expected to
decrease in cost
based on current
and world demand.
In addition, SRS’s
electrical rates
have also increased
dramatically over
the last two years
based on the
increased costs of
coal and natural
gas that the Site’s
electrical supplier
must recoup through
its electric rates
that have been
approved by the
South Carolina
Public Service
Commission. These
baseline rates will
be escalated in
accordance with
NIST standards.


Throughout the
performance period,
Ameresco will be
supplied utilities
at no cost but the
consumption data
will be metered and
supplied to the
Site’s utility
department to be
included in
calculating the
true cost of
generating steam
and/or electricity
from the new
biomass plants for
inclusion in Site
supplied utilities.

	RESPONSIBILITY/DESCRIPTION	 	AMERESCO’S PROPOSED APPROACH	 	DOE-SR ASSESSMENT
	c.    Construction costs: The
Contractor is responsible for
determining construction costs
and defining a budget. In a
fixed-price design/build
Contract, the agency assumes
little responsibility for cost
overruns. However, if
construction estimates are
significantly greater than
originally assumed, the
Contractor may find that the
project or measure is no
longer viable and drop it
before Contract award. In any
design/build Contract, the
agency loses some design
control. Clarify design
standards and the design
approval process (including
changes) and how costs will be
reviewed.


	 	A significant portion of Ameresco’s
business is focused on energy
engineering, design and consulting.
Ameresco staff, complemented by
subcontracted experts, are
developing the ECM designs for this
proposal. Additionally, Ameresco’s
in-house construction management
team has collaborated extensively
with the design team, potential
subcontractors, and equipment
suppliers to assure project
constructability, review budgeted
costs, and provide insight into
procurement options. Having all
these functions involved throughout
the DES Phase substantially lowers
the risk of construction cost
overruns, and ensures a realistic
and balanced approach to innovation
and realism in project design.


To manage the risk associated with
escalating prices for construction
materials and equipment, Ameresco
will hold material and labor
pricing set forth in Schedule DO 2
included herein through May 15,
2009. The proposal acceptance
period may be extended; however,
there may be changes in project
pricing. The parties will share
the risk of construction cost
increases that occur prior to
contract award; however, Ameresco
will assume sole responsibility for
cost increases occurring in normal
market conditions after contract
award as well as responsibility for
managing the risks of such
increases. However, should cost
increases be caused by
extraordinary market conditions,
the parties will negotiate changes
to the construction completion
schedule and/or financial terms of
the contract as mutually agreeable
to both parties.
	 	Upon submittal of
the Revised Final
Proposal, a Cost
Reasonableness
Review of
Ameresco’s
Implementation
Costs will be
performed.
Ameresco shall
submit a breakdown
of the
Implementation
costs with the
Revised Final
Proposal to allow
the DOE-SR to
perform the review.

RISK/RESPONSIBILITY MATRIX







	 	 	 	 	 
	RESPONSIBILITY/DESCRIPTION	 	AMERESCO’S PROPOSED APPROACH	 	DOE-SR ASSESSMENT
	 

	 	Design-build will be the means of
project implementation, and the
proposed project will be designed
and constructed to meet industry
and those local SRS standards
identified in this proposal, and
included with the contract award.	 	 
	 
	 	 	 	 
	 

	 	[**].	 	 
	 
	 	 	 	 
	 

	 	The basic contract establishes
maximums for Ameresco mark-ups for
both the implementation and
performance periods. Mark-ups
proposed in this proposal are below
the maximums allowed by the BAMF
Contract. Mark-ups associated with
changes resulting from concealed or
environmental conditions of the
project site, customer requests, or
a change in contract requirements
will be negotiated at the time the
change is incorporated into the
contract delivery order, but shall
never exceed the maximum allowed by
the BAMF Contract.	 	 
	 
	 	 	 	 
	d.    M&V costs: The agency
assumes the financial
responsibility for M&V costs
directly or through the
Contractor. If the agency
wishes to reduce M&V cost, it
may do so by accepting less
rigorous M&V activities with
more uncertainty in the
savings estimates. Clarify
how project savings are being
verified (e.g. equipment
performance, operational
factors, energy use) and the
impact on M&V costs.


	 	Ameresco proposes that M&V Option B
– ECM Isolation be used to verify
the performance of ECM 1 and ECM 2.
Project performance will be
continuously metered and reported
to the DOE-SR on a monthly basis.
The metering equipment installed
for the project, in combination
with the established baseline
energy costs and NIST-based annual
adjustments, will provide
sufficient M&V of project
performance without unnecessarily
increasing project costs. Section
4.4 describes the M&V plan in
detail.
	 	The DOE-SR concurs
with the M&V
approach for the
project.

RISK/RESPONSIBILITY MATRIX




	 	 	 	 	 
	RESPONSIBILITY/DESCRIPTION	 	AMERESCO’S PROPOSED APPROACH	 	DOE-SR ASSESSMENT
	 

	 	Performance Period M&V costs are
escalated annually at a fixed rate
of [**]%.	 	 
	 
	 	 	 	 
	e.    Non-Energy Cost Savings:
The agency and the ESCO may
agree that the project will
include savings from recurring
and/or one-time costs. This
may include one-time savings
from avoided expenditures for
projects that were
appropriated but will no
longer be necessary.
Including one-time cost
savings before the money has
been appropriated entails some
risk to the agency. Recurring
savings generally result from
reduced O&M expenses or
reduced water consumption.
These O&M and water savings
must be based on actual
spending reductions. Clarify
sources of non-energy cost
savings and how they will be
verified.


	 	Both proposed ECMs will result in
the shutdown of existing DOE-SR
operated plants eliminating
significant O&M expenses currently
incurred by SRS. The O&M cost
baseline is presented for each ECM
and was developed based on
information, and is collaborative
effort between Ameresco, SRS and
M&O technical personnel.


The annual O&M savings have been
escalated annually at a fixed rate
of [**]%.


NOTE: There will be a significant
reduction in the consumption of
water taken from the Savannah
River, although no cost savings
related to such reduction in water
usage have been included in this
proposal.
	 	The DOE-SR has
provided actual O&M
costs for both the
D-Area Powerhouse
and the K-Area
Package Boilers.
The DOE-SR will
review such costs
included in the
Revised Final
Proposal and, if
acceptable,
provide its
concurrence.
	 
	 	 	 	 
	f.    Delays: Both the
Contractor and the agency can
cause delays. Failure to
implement a viable project in
a timely manner costs the
agency in the form of lost
savings, and can add cost to
the project (e.g.,
construction interest,
remobilization). Clarify
schedule and how delays will
be handled.


	 	Ameresco will fully support the
DOE-SR during the review, approval,
and award of the proposed ECMs to
mitigate potential delays as much
as is within Ameresco’s control.
Further, Ameresco will honor the
pricing proposed herein through May
15, 2009; delays in contract award
beyond that time may result in
increased project cost and will
result in project implementation
delays.


Major milestones for obtaining
project approvals, delivery order
award, and project implementation
are indentified in Table 1.7
herein. Ameresco will provide a
	 	SRS will fully
support Ameresco
during the review,
approval, and award
of the proposed
ECMs to mitigate
potential delays,
and award the
Delivery Order on
schedule. In
addition, DOE and
the M&O Contractor
will work with
Ameresco to
facilitate a smooth
mobilization to the
Site and coordinate
the interfaces for
key support requirements
provided by SRS. Critical interface
requirements should be identified on
Ameresco’s schedule to allow for
adequate up front coordination.

closely monitored throughout the
construction phase by Ameresco’s
on-site management team as well as
corporate management. Their
proactive involvement will mitigate
the occurrence of delays. Should a
delay occur, Ameresco management
will immediately develop a
mitigation plan, discuss it with
the DOE-SR staff, and then take the
necessary actions to ensure the
project remains on schedule.


Schedule Risks & Mitigation

Schedule Delays

The potential for schedule delays
will be constantly monitored, and
immediate and appropriate
mitigation actions will be taken by
Ameresco management personnel if
necessary. The schedule is being
structured both logically and
realistically to minimize the
potential for delays; however,
should an unavoidable delay occur,
Ameresco will work closely with
DOE-SR engineers to determine the
best course of action and, if
necessary, a revised schedule will
be developed and proposed. The
primary objective of any revision
will be to get the work back on
track without extending the
completion date.


Subcontractor Management

firms and will continue to
pre-qualify firms that may be
selected as

However, Ameresco will continue to
evaluate qualifications and the
firm’s current workload prior to
executing any subcontracts. If
manpower later becomes an issue,
Ameresco will either direct the
firm to hire additional personnel,
hire additional subcontractors, or
replace the subcontractor.


Ameresco will manage subcontractors
and suppliers through close control
and monitoring of all critical
activities. Monitoring and
controls include the following
procedures: weekly progress
meetings, schedule updates, and
materials management plan.


Late Delivery of Materials/Equipment

In order to protect against late
delivery of material or equipment
and keep the project on schedule,
Ameresco will implement and
maintain a materials management
plan and constantly monitor
production and delivery dates.

	 	The SRS is not considered a
candidate for closure at any time
in the foreseeable future. Based
on information provided by SRS
personnel, a build-up in operations
is projected to continue past 2020.
The electrical and steam demand
are projected to change in future

	 	benefits to the DOE-SR; steam for
thermal processes and electricity.
Should changes at the facility
result in reduced thermal
requirements, Ameresco will produce
more electricity. The first
priority will be to satisfy the
site’s steam needs. Should there
be excess capacity (delta between
guaranteed steam production and
site steam requirements) the steam
will be processed through a turbine
to produce electricity. The
versatility of the process to
satisfy both thermal and electrical
needs of the site mitigates this
risk.


Ameresco has assessed the potential
for closure of the site and
considers it a minimal risk at this
time. However, if SRS should close
or experience a significant
reduction, then Ameresco will be
responsible for characterizing and
quantifying the impact of the
changes on the project. In a
severe case, though highly
improbable, it may necessitate
either a partial or full
termination for convenience;
however, the contract will include
a Termination Liability Schedule to
facilitate arriving at appropriate
termination costs. If a
termination becomes necessary,
Ameresco would comply with the
applicable Federal Acquisition
Regulation (FAR) and Department of

impact on the operations of the
proposed ECMs unless increased
operating hours contributes to the

ECM 2, the K and L Area plants will
operate 24/7 as necessary over
approximately a four month period
each year to meet building heating
loads. Although operating hours
are pre-determined, steam delivery
requirements will be both
pre-determined and measured.


Over the past two years, SRS’
energy consumption has been
relatively consistent in
conjunction with the operating
hours. Therefore, the energy
baseline and guarantees assume
predetermined operating hours for
the term of the delivery order;
however, Ameresco will guarantee an
annual quantity of steam production

intensity of use (e.g. changes
in occupancy or level of
automation). Changes in load
can show up as increases or
decreases in “savings”

Clarify whether equipment
loads are to be measured or
stipulated and what the impact
will be if they change. If
the equipment loads are
stipulated, the baseline
should be carefully documented
and agreed to by both parties.



	 	projections shown in Table
1.1, which were provided by site
personnel and are assumed by
Ameresco to be correct. Decreasing
steam requirements will be
accommodated by increasing net
green power generation. Increasing
steam requirements above ASG
(excess production) will be
accommodated up to the maximum
plant capacity. Compensation for
the excess steam production will be
included in the annual cost
adjustment.


It is proposed that the DOE-SR and
Ameresco share the risk of
increased load requirements.
Ameresco will assume responsibility
for providing the steam to meet
increased loads up to the maximum
plant capacity. However, Ameresco
will be compensated for steam
deliveries above the guaranteed
annual production quantities as
provided for by the fuel adjustment
provision found in Section 1.3.1.2
of this proposal.	 	 
	 
	 	 	 	 
	c.    Weather: A number of
energy efficiency measures are
affected by weather. Neither
the Contractor nor the agency
has control over the weather.
Changes in weather can
increase or decrease “savings”
depending on the M&V method
(e.g. equipment run hours
multiplied by efficiency
improvement vs. whole building
utility bill analysis). If
weather is “normalized,”
actual savings could be less
than payments for a given
year, but will average out
over the long run. Clearly
specify how weather
corrections will be performed.


	 	Neither Ameresco nor the DOE-SR has
control over the weather and
changes in weather can increase or
decrease the amount of steam needed
by SRS facilities. However, the
metric for determining whether
Ameresco has satisfied its
performance guarantees are not
weather dependent; therefore,
weather corrections are not be
necessary. Ameresco proposes that
no weather corrections be made as
neither ECM will be significantly
impacted by the weather since the
baseline has been developed from
historical consumption data.


NOTE: Although weather could
impact the amount of steam needed
for heating purposes, that risk has
been

	 	addressed by increased
electrical generation as outlined
in paragraph b above.	 	 
	 
	 	 	 	 
	d.    User participation: Many
energy conservation measures
require user participation to
generate savings (e.g. control
settings). The savings can be
variable and the Contractor
may be unwilling to invest in
these measures. Clarify what
degree of user participation
is needed and utilize
monitoring and training to
mitigate risk. If performance
is stipulated, document and
review assumptions carefully
and consider M & V to confirm
the capacity to save (e.g.
confirm that the controls are
functioning properly).


	 	Ameresco will operate and maintain
the systems proposed under both
ECMs as defined in Section 5.2.7.1.
The ECMs will interconnect with
site utility distribution systems
that will be maintained by the site
M&O Contractor, as is currently the
case. The DOE-SR will be the end
user of the steam produced by the
Ameresco plants. The Government
must accept steam deliveries and
the site M&O contractor must ensure
utility services are available for
the ECMs to be effective. The risk
of either the DOE-SR not accepting
steam deliveries (within the
baseline amounts) or the utility
systems being down over prolonged
period of time is minimal.
	 	The DOE-SR
agrees with
Ameresco’s proposed
approach.
	 
	 	 	 	 
	3.    PERFORMANCE:

	 	 	 	 
	 
	 	 	 	 
	a.    Equipment performance:
Generally the Contractor has
control over the selection of
equipment and is responsible
for its proper installation,
commissioning, and
performance. Generally the
Contractor has responsibility
to demonstrate that the new
improvements meet expected
performance levels including
specified equipment capacity,
standards of service, and
efficiency. Clarify who is
responsible for initial and
long-term performance, how it
will be verified, and what
will be done if performance
does not meet expectations.


	 	Ameresco will retain responsibility
for the performance of the
equipment throughout the term of
the performance period for both
ECMs as defined in Section 5.2.7.1.
Ameresco has experience and is
familiar with the equipment. It
selected the equipment based upon
efficiency, performance level, and
reliability, and in conjunction
with the manufacturer’s service and
performance guarantees.
Performance of the equipment will
be reflected in the annual M&V
documentation provided by Ameresco.
	 	The DOE-SR agrees
with Ameresco’s
proposed approach.
	 
	 	 	 	 
	b.    Operations: Responsibility
for operations is negotiable,
and it can impact performance.

impact performance. Clarify
how long-term preventative
maintenance will be assured,

maintenance checklist and
reporting frequency). Clarify
who is responsible for
long-term preventive
maintenance to maintain
operational performance

Clarify what will be done if
inadequate preventive
maintenance impacts
performance.


	 	Ameresco assumes responsibility for
all maintenance and repairs of the
equipment installed in the new
facility under the contract term as
defined in Section 5.2.7.1.
This includes a preventative
maintenance program, incidental
repairs, and warranty work.
Ameresco will verify performance of
the maintenance on an on-going
basis, with an in-depth review of
the maintenance program conducted
during annual performance
reconciliation. The ongoing costs
of operations and maintenance for
the equipment is included in the
performance period expenses and
escalated annually at [**]% for the
duration of the performance period.

6.0 PROPOSAL PRICING INFORMATION



Schedules DO-1 through DO-5(a) (the “DO–Schedules”) presented at the end of this section
provide the economic and financial details of the proposed project based on SRS making annual debt
service payments at the beginning of each performance period and monthly performance period
expenses.



In addition to price quotes and estimates provided by suppliers and vendors, price estimates were
developed using Ameresco software cost models, historical project cost data, and cost estimating
guides (e.g. RS Means, etc.).




6.1 Interest Rate



Ameresco’s locked interest rate of 8.19% as shown on Schedule DO-3 is based on Moody’s AA
Corporate Index, as published by Bloomberg on May 12, 2009, of 6.14% plus a spread above the Index
of 2.05%.




6.2 Finance Procurement Price



The finance procurement price set forth on Schedule DO-3 consists of the following three
components and will fluctuate until the project interest rate mentioned above is fixed:





	 	a)	 	Performance/Payment Bond — Performance and payment bonds are a requirement
of the Contract. The performance bond is purchased by Ameresco to protect the
Government and the third party lender against Ameresco non-performance during the
implementation period. The performance bond applies only to the installation portion
of the work under this contract and does not apply in any way to energy savings
guarantees, payments or maintenance provisions, except that the performance bond shall
guarantee that the installation will be free of defective materials and workmanship
for a period of twelve (12) months following completion and acceptance of the work.
Ameresco’s lender will require the execution a Dual-Obligee Rider naming such lender
as an additional or dual-obligee under the performance bond.
	 
	 	b)	 	Interest During Construction (“IDC”) – This cost represents the interest
costs accruing to Ameresco during the proposed implementation period. Ameresco’s
DO-Schedules assume a traditional upfront funding of the Total Amount Financed into
an interest bearing escrow account upon award of the contract, Ameresco will be
charged interest on the amount funded at the project interest rate and will net these
interest charges with interest earnings on the escrow account’s remaining principal
balance. Ameresco will receive progress payments

	 	Contract DE-AM36-02NT41457







	 	 	 	for implementation expenses from the escrow account. In addition to the traditional
escrow funding approach, Ameresco is exploring a delayed funding structure in lieu of
the traditional escrow funding structure proposed herein. Under the delayed funding
structure, Ameresco’s lender will advance progress payments to Ameresco periodically
during the construction period. Interest will begin to accrue only on the progress
payments made to Ameresco and accrued interest will negatively amortize the outstanding
balance. Ameresco believes if it is able to utilize the delayed funding structure it
will provide significant savings on interest during construction.
	 
	 	c)	 	Finance Processing Fee – The finance processing fee represents expenses
Ameresco will incur to finance the contract. Typically, this fee is a combination of
the following applicable expenses: legal fees, origination fees, fees for rating
agencies, rate lock fees to fix the interest rate during the implementation period,
trustee or fiscal agent fees, and any rate buydown costs.





6.3 Sales Tax



Ameresco intends to pursue a sales tax exemption with the South Carolina Department of Revenue
(“SCDOR”) with respect to the ECM equipment pursuant to S.C. Code Ann. section 12-36-2120(29).
This exemption provides the following sales are exempt from sales tax: “tangible personal property
purchased by persons under a written contract with the federal government when the contract
necessitating the purchase provides that title and possession of the property is to transfer from
the contractor to the federal government at the time of purchase or after the time of purchase.
This exemption also applies to purchases of tangible personal property which becomes part of real
or personal property owned by the federal government or, as provided in the written contract, is to
transfer to the federal government. This exemption does not apply to purchases of tangible
personal property used or consumed by the purchaser.” The SCDOR also issued South Carolina Revenue
Ruling No. 04-9, which outlines the requirements for contractors to qualify for the
exemption contained in S.C. Code Ann. section 12-36-2120(29). For the contractor’s purchases to
be exempt from sales tax, the contractor must have a written contract with the federal government
which provides that title and possession of the property is to transfer from the contractor to the
federal government at the time of purchase or after the time of purchase and such title and
possession actually transfers to the federal government in accordance with the contract or the
property becomes part of a real or personal property owned by the federal government or is to
transfer to the federal government.



Ameresco must obtain an exemption certificate issued by the SCDOR to purchase tangible personal
property exempt from sales tax. Ameresco will submit an application (S.C. Form ST-10G) together
with a copy of the executed contract to obtain the required exemption certificate. Due to the fact
that Ameresco will not receive an exemption certificate until after contract award is executed,
Ameresco has included a sales tax reserve in its proposal in the approximate amount of $4,600,000.
Should Ameresco receive an exemption certificate, Ameresco will request that its lender deposit the
sales tax reserve into the PPEF upon the Government’s acceptance of the ECMs. Ameresco proposes to
wait until acceptance

to fund the PPEF with the sales tax reserve to avoid paying interest on such reserve during the
construction period. To the extent that Ameresco is denied an exemption certificate by the SCDOR,
Ameresco will notify the Government of such determination and the sales tax reserve shall be
dispersed to Ameresco by its lender via progress payments.




6.4 Property Tax



Title to all contractor-installed equipment associated with each ECM shall vest in the
Government. Therefore, the Government is the owner of all contractor-installed equipment for
property tax purposes and Ameresco has not included property taxes in this proposal. In the event
the Government elects not to accept title to the contractor-installed equipment, Ameresco would
need to revise this proposal to include all applicable property taxes.




6.5 Insurance



Ameresco will maintain builder’s risk insurance coverage on all contractor-installed equipment
during the implementation period. Ameresco’s proposal does not include any cost related to
insuring any contractor-installed equipment post-acceptance. Title to all equipment installed by
Ameresco shall be vested with the Government after acceptance by the Government of the commercial
operation of such ECM and the Government will self-insure all such Contractor-installed equipment
throughout the Delivery Order term for the Total Amount Financed as shown on Schedule DO-3. This
acceptance shall not relieve Ameresco’s responsibility for ECM performance. Ameresco will be
responsible for operating and maintaining all ECMs throughout the contract term as set forth
herein. If such Ameresco-installed equipment is damaged or destroyed, for reasons beyond the
control and without the fault or negligence of Ameresco, the Government shall have the option to
(i) terminate the Delivery Order (either in part or in whole) and hold Ameresco harmless for the
savings and performance associated with the damaged or destroyed equipment for the remainder of the
term, (ii) pay Ameresco, by separate contract action to repair or replace the damaged or destroyed
equipment and continue making its scheduled payments to Ameresco, or (iii) repair or replace the
damaged or destroyed equipment at its cost and continue making its scheduled payments to the
Ameresco. If the repair/replacement work is performed by any party other than Ameresco, a
commissioning of the repair/replacement work must be conducted, witnessed and approved by both the
Government and Ameresco. This requirement is necessary for Ameresco to continue to guarantee the
related energy savings as set herein.




6.6 Payment/Term



Ameresco will submit its initial invoice for payment with respect to an ECM upon the earlier
of (i) completion of the ECM and acceptance by the Government or (ii) when the Government has
beneficial use of such ECM. Following the initial invoice submittals by Ameresco, Ameresco will
invoice the Government on or before the first day of April each year thereafter such that the
Government’s annual

Debt Service payment will be paid annually on or before the first day of May. Performance Period
Expenses will be paid monthly on the first day of each month in an amount equal to one-twelfth
(1/12) of the Total Performance Period Expenses due for each Performance Period.
Submission of or revisions to the Post Installation Completion Report, As-Built drawings, or
O&M Manuals, or delays in providing training that do not affect savings, shall not delay acceptance
with respect to the commencement of making payments to Ameresco, but will be noted as punch list
items and addressed by Ameresco in a timely manner. Ameresco is proposing annual debt service
payments be made at the beginning of each performance period because it reduces the principal
balance the fastest and results in the lowest interest expense to the Government. The annual debt
service period will occur and payment will be due prior to Ameresco’s submission of the applicable
year’s Annual M&V Report. However, any shortfall in Annual Savings set forth in such report will
be adjusted from future performance period payments as provided in Section G.4 of the BAMF
Contract. Payments from the government will be applied first to prompt payment interest, then to
performance period expenses, then to interest and then to principal.




6.7 Cancellation/Termination/Buyout



Schedule DO-5(a) — Termination Liability Schedule is provided with this proposal in addition
to Schedule DO-5. Schedule DO-5(a) provides an amortization of the project’s outstanding principal
balance along with the calculation used to determine the Termination Liability and is provided for
use in the event that the Government prepays or terminates the project for its convenience.
Schedule DO-5(a) represents Ameresco and its third-party lender’s recovery of allowable contract
expenditures, and associated profit, incurred as of the date of termination or buyout and assumes
all payments are received by Ameresco (or its assignee) when due. The column titled “Outstanding
Principal Balance” represents Ameresco’s recovery of costs associated with the installation work in
connection with implementing the ECMs. The column titled “Lender’s Termination Premium” over the
original project cost represents the third-party lender’s immediate recovery of administrative,
placement, legal, and investment banking expenses associated with the original financing as well as
its termination. These financing costs are not represented in the project cost as a line item, but
are built into the interest rate spread and recovered over time as debt service. If Schedule
DO-5(a) only reflected the project costs, Ameresco’s third party lender would fail to recover their
allowable contract expenses and associated profit in the event of a termination or buyout. The
lender’s termination premium is a cost recovery alternative that the third-party lender must rely
on in the event of a termination or buyout in lieu of amortizing fees and costs over time.



In the event of a termination for convenience in whole, cancellation in whole, or prepayment in
whole, the Government acknowledges and agrees that it shall be obligated to pay the specific
Termination Liability amount set forth on Schedule DO-5(a) for the month corresponding to the
effective date the Government intends to make payment to Ameresco. In the event of a termination
for convenience in part, cancellation in part or reduction in requirements in part, the Government
acknowledges and agrees that Ameresco shall apply any such payment made by the Government to the
Outstanding Balance and Lender’s Termination Premium amounts set forth on Schedule DO-5(a)
corresponding to the effective date of such payment in part. Following the application of such
payment in part, the Government will enter into a contract

modification to incorporate a revised Schedule DO-5(a) reflecting, at the Government’s option, a
reduction in the total number of payments or reduction in amount per payment over the remaining
term such that, in either case, the Outstanding Principal Balance is fully repaid. In the event of
a prepayment or buydown, the Government acknowledges and agrees that Ameresco shall apply any such
payment made by the Government as set forth in Section 6.8 below.



Any termination for convenience of the Performance Period portion of the contract shall be handled
in accordance with FAR 52.249-2.




6.8 Prepayments/Buydowns



In the event the Government chooses to make prepayments or buydowns during the performance
period of the contract term, with the purpose of reducing the outstanding unamortized balance of
the financing for the ECMs, and thereby reducing the price/payments and overall term of the
contract, the following method shall be used to apply those prepayments to the delivery order
price:



The prepayment amount will be placed by the third-party financier into an account to be identified
in the prepayment modification to the delivery order, to be reinvested at a fixed rate, and at
which rate the amount shall earn and accrue interest, for the shorter of (a) the remaining term of
the delivery order, as revised by delivery order modification of the award Schedules at the time of
any prepayment; or (b) the period up to the date the delivery order may be terminated by the
Government. Determination of the fixed rate at which the prepayment amount shall earn and accrue
interest shall be by mutual agreement of the parties based on then-current reinvestment rates. The
sum of (i) the prepayment amount and (ii) projected accrued interest shall be the total amount
applied against the remaining delivery order payments, as reflected in the task order, in reverse
order of the scheduled contract payments. Thereby, the scheduled term of the contract shall be
reduced, and the payment schedule revised and overall price reduced, as reflected in a revised
schedule incorporated into the contract by modification. A revised schedule will also be provided
and incorporated into the delivery order award by modification. This process may be repeated to
incorporate subsequent prepayments.




6.9 Protection of Financier’s Interest



All cure or show-cause notices or notices of default will be mailed by the Government to
Ameresco’s assignee, as set forth in the Notice of Assignment delivered to the Contracting Officer,
at least 15 days in advance of any termination of this contract for default. The Government will
consider requests by such assignee to extend the applicable cure or show-cause response period so
long as such cure is being diligently pursued.

6.10 Security Interest in ECM Equipment



During the implementation period and prior to title to the ECM equipment vesting in the
Government, the Government agrees to subordinate any security interest it may have in any Ameresco
installed ECM equipment to Ameresco’s lender, and grants such lender a first priority security
interest in the ECM equipment. Upon the Government’s acceptance of each ECM, Ameresco will cause
its lender to release its security interest in such ECM equipment and to deliver evidence of such
to the Contracting Officer.




6.11 Assignment of Claims



Pursuant to DOE FAR subpart 932.803 Policies, Ameresco proposes to finance the ECMs through an
assignment of the Government’s payments under the contract awarded in connection with this proposal
in compliance with FAR 52.232-23 Assignment of Claims, Alternate I (Apr 1984). Ameresco or its
lender will remit to the Government the required Notice of Assignment together with the Instrument
of Assignment. The Government agrees to acknowledge receipt of such notice and incorporate such
assignment in a contract modification.




6.12 Title to and Responsibility for Contractor-Installed Property



The Government acknowledges that, with respect to the ECMs, the Government is obligated to
accept delivery thereof pursuant to the contract upon satisfaction of the conditions thereto.
After acceptance by the Government of the installed ECMs and vesting of title with the Government
to the equipment installed by Ameresco, the Government agrees that there shall be no withholding,
reduction or setoff by the Government in the payment of the specific amounts as set forth in the
row labeled “TOTAL DEBT SERVICE” on Schedule DO-3 as a result of (i) any termination for default,
in whole or in part, pursuant to FAR Clause 52.249-8 (Default-Fixed Price Supply and Service) by
the Government of the Performance Period (as defined in Modification M005 to Contract No.
DE-AM36-02NT41457, Section J, Attachment 1) portion of the contract, or (ii) any costs assessed
against Ameresco pursuant to FAR Clause 52.246-4 (Inspection of Services-Fixed Price).



In the event of any termination for default, in whole, of the Performance Period portion of the
contract, the Government may elect to, but in no way is obligated or required to, buyout the
Ameresco installed equipment by paying the sum of the columns labeled “Outstanding Principal
Balance” and “Lender’s Termination Premium” on Schedule DO-5(a) for the month corresponding to the
effective date of such termination (the “Buyout Amount”). In the event of such an election by the
Government, the Government agrees that, with respect to the Buyout Amount, there shall be no
withholding, reduction or setoff by the Government in the payment thereof.



In the event of any termination for default, in whole or in part, of the Performance Period portion
of the contract pursuant to FAR Clause 52.249-8 (Default-Fixed Price Supply and Service) or
assessment of costs against Ameresco pursuant to FAR Clause 52.246-4 (Inspection of Services-Fixed
Price), the

Government reserves the right to exercise any and all of its rights and remedies against Ameresco
(including any and all rights to recover excess reprocurement costs that the Government may incur
as a result of Ameresco’s default and/or Ameresco’s failure to perform the Performance Period
portion of the contract), except for the withholding, reduction or setoff restrictions expressly
provided for herein.




6.13 Construction Milestones



The Government agrees, from time to time during the implementation period, to provide its
written acknowledgement of the satisfaction of certain predetermined construction milestones set
forth on Table 1.7 Project Milestones. Any such acknowledgement by the Government will not
constitute acceptance of the ECM on the part of the Government and will not require the Government
to commence making payments until such ECM is operational as described herein.

	Fluidized Bed Combustors
	 	Page 1 of 3










Fluidized bed combustion systems use a heated bed of sand-like material suspended (fluidized)
within a rising column of air to burn many types and classes of fuel. This technique results in a
vast improvement in combustion efficiency of high moisture content fuels, and is adaptable to a
variety of “waste type fuels. The scrubbing action of the bed material on the fuel particle
enhances the combustion process by stripping away the carbon dioxide and char layers that normally
form around the fuel particle. This allows oxygen to reach the combustible material much more
readily and increases the rate and efficiency of the combustion process.








Bed Recycle System



The key to EPI’s dominance of the difficult waste fuel combustion market is our patented bed
recycle system. EPI is the only company that offers uniform bed drawdown, integrated air cooling
and automatic cleaning and reinjection of the bed material. This innovative feature enables EPI
systems to operate on fuels with significant quantities of 4-inch minus noncombustible tramp
material (contaminants such as rocks, metal. etc.). In grate style systems, tramp materials and ash
slag can cause significant problems requiring a shutdown to correct. In other fluidized bed
systems, tramp materials can build to the point that fluidization is no longer possible allowing
clinkers to form. In these systems, a shutdown is usually also required to clean out the
accumulation.




Complete and Efficient Combustion.







The turbulence in the combustor vapor space combined with the tumultuous scouring effect and
thermal inertia of the bed material provide for complete, controlled and uniform combustion. These
factors are key to maximizing the thermal efficiency, minimizing char, and controlling emissions.
The high efficiency of a fluid bed combustor makes it particularly well suited to problem fuels
with low BTU value and high moisture characteristics. EPI’s systems have consistently achieved high
combustion efficiencies. In typical units, the carbon burnout percentages within the combustor are
well in excess of 99 percent.




Waste Fuel Diversity



EPI systems have operated on fuels as diverse as agricultural waste, municipal solid waste, wood
wastes, industrial and municipal sludges, plastic, tires and coal. Fluidized bed systems are also
capable of efficiently combusting fuels of varying consistency. EPI units have demonstrated the
ability to handle a variety of wastes within a single combustor. EPI’s San Joaquin Valley Energy
Project units have logged operating time over 68 varieties of agricultural and urban wood waste.
EPI’s patented bed cleaning system, which removes large non-combustible material from the bottom of
the bed, allows EPI units to burn otherwise problematic fuels with a minimal amount of processing.

Low Emissions



Emissions from a fluidized bed unit are inherently lower than conventional technologies for the
following reasons:





		 	Low combustion temperatures and low excess air within the bed reduces the formation of certain
emissions such as NOx.
	 
		 	High combustion efficiency results in flue gases that contain low amounts of CO.
	 
		 	Emissions such as SOx and NOx may be abated within the fluidized bed system by
injecting limestone into the bed and ammonia into the vapor space.




These features of fluidized bed combustion, combined with EPI’s vast experience with a variety of
fuels have allowed EPI units to comply with some of the most stringent air quality regulations in
the country, including six operating plants in California. EPI units have consistently been
accepted as the Best Available Control Technology “BACT” by environmental regulatory agencies.




Favorable Ash Properties



The high combustion efficiency of a fluid bed results in a reduced amount of inorganic material as
fine ash. The remaining larger material consists mainly of non-combustibles, such as rocks, and
wire brought in with the fuel, and coarse sand-like neutral particles. Low combustion temperatures
in the fluidized bed minimize the formation of toxic materials that might go into the ash. Ash
samples from EPI systems have consistently tested nontoxic, and in many instances the ash is being
sold as input for other products such as cement.




Operating Flexibility



EPI’s fluidized bed systems have demonstrated the ability to operate under a wide range of load
conditions. The thermal “flywheel” effect of the bed material allows swings in moisture and heating
content of the fuel to be absorbed by the system without negative impact. Conversely, the low fuel
inventory present in the unit makes it very responsive to varying loads. The fluidized bed also
maintains efficiency during system turn-down. The operating flexibility demonstrated by existing
EPI units has proven quite valuable for some of EPI’s customers allowing them to take advantage of
utility incentive programs for generation that follows electric demand.




Low Operating Costs



The lack of moving parts in a fluid bed reduces maintenance costs and down time. EPI units have
achieved operating availabilities above 98% and have kept operating costs relatively low given the
difficult fuels they are burning.




Environmentally Sound Energy Production from Waste



Fluidized bed combustion is an environmentally favorable, proven technology for disposal of solid
wastes and generation of energy. The combination of EPI’s vast experience in developing solutions
for a wide variety of applications, with the favorable characteristics of

solutions.

fine ash. The remaining larger material consists mainly of non-combustibles, such as rocks and
wire brought in with the fuel, and coarse sand-like neutral particles. Low combustion temperatures
in the fluidized bed minimize the formation of toxic materials that might go into the ash. Ash
samples from EPI systems have consistently tested nontoxic, and in many instances the ash is being
sold as input for other products such as cement.




Operating Flexibility



EPI’s fluidized bed systems have demonstrated the ability to operate under a wide range of load
conditions. The thermal “fly-wheel” effect of the bed material allows swings in moisture and
heating content of the fuel to be absorbed by the system without negative impact. Conversely, the
low fuel inventory present in the unit makes it very responsive to varying loads. The fluidized bed
also maintains efficiency during system turn-down. The operating flexibility demonstrated by
existing EPI units has proven quite valuable for some of EPI’s customers allowing them to take
advantage of utility incentive programs for generation that follows electric demand.




Low Operating Costs



The lack of moving parts in a fluid bed reduces maintenance costs and down time. EPI units have
achieved operating availabilities above 98% and have kept operating costs relatively low given the
difficult fuels they are burning.




Environmentally Sound Energy Production from Waste



Fluidized bed combustion is an environmentally favorable, proven technology for disposal of solid
wastes and generation of energy. The combination of EPI’s vast experience in developing solutions
for a wide
variety of applications, with the favorable characteristics of fluidized bed combustion make EPI
the leader in providing environmentally sound waste disposal solutions.

The Hurst HD Hybrid Series combines the benefits of a watertube furnace along with a multi-pass
firetube boiler vessel. The resulting efficiency of the Hybrid design is higher than conventional
packaged boilers. This efficiency is achieved by superior utilization of the fuel’s radiant heat
within the water-cooled furnace as well as the Hybrid’s balanced multi-pass firetube vessel
resulting in low stack temperatures.







The HD Series will efficiently burn any liquid or gaseous fuel and is available from 100 to 2500
horsepower with pressures of 160-PSI hot water or 450-PSI steam.







 









 








Solid Fuel Fired Steam Boilers







Hurst Hybrid Series involves years of engineering and construction of the wood, coal, and solid
waste fired fuel systems.  
The Hybrid design combines the benefits of a watertube furnace along
with a multipass firetube boiler vessel. The resulting efficiency of the Hybrid design is higher
than conventional solid fuel boilers. This efficiency is achieved by superior utilization of the
fuels radiant heat within the water cooled furnace as well as the Hybrid’s balanced multi-pass
firetube vessel resulting in low stack temperatures. The Hybrid is adaptable to dry wood, wet wood,
coal and an array of other waste fuels. Furthermore, the watertube furnace allows for efficient
firing of auxiliary fuels (gas, fuel oil, and waste oil).








FEEDWATER DEAERATORS




WHY DEAERATE?




     The use of deaerators has long been used in power plants and water tube type boilers, primarily
because they remove undissolved oxygen and raise the temperature of the feedwater. These advantages
are important today for firetube boilers as well, due to higher capital investments.



     Operating costs can be reduced by recovering flash steam when returned by high temperature
condensate. This feature also raises the feedwater temperature, thus requiring less boiler fuel to
convert the feedwater to useable steam.



     Boiler tubes, condensate lines, and process piping have a much longer useful life by eliminating
the pitting action of untreated water. This advantage alone justifies the cost of an “OXY-MISER”
deaerator.

GENERAL INFORMATION:




APPLICABLE STANDARDS:



The machines are designed, manufactured and tested according to standards ABNT, NEMA, IEEE, IEC
and DIN, where applicable. Specifically we can mention:




NBR 5110 — Cooling methods.

NBR 5052 — Synchronous machines.

NBR 5117 — Synchronous machines.

ISO 1940 — Balancing quality.

VDE 0530 — Turning electrical machines.

NEMA MG-1 Part 32 and 33 — Synchronous Generators.




GENERAL CONSTRUCTION:



An alternating-current generator consists essentially of a magnetic circuit, dc field winding, ac
armature winding and mechanical structure, which includes cooling and lubrication. The magnetic
circuit and field windings are arranged in certain way that, as the machine spins, the magnetic
flow linking the armature windings




 









 







changes cyclically, and for this reason induces alternate voltage in armature winding.



There are many possible geometrical arrangements for these elements, and each one with its own
advantages. Usually the salient pole construction is used for low speed rotors such as the ones
used in diesel an hydroelectric power stations, and the cylindrical rotor machine for
steam-turbine driven generators. WEG’s standard for high-speed application is the cylindrical
rotor type because of the lower centrifugal forces created, and also because it
lessens/eliminates some harmonics and high frequency interference with other equipments.




FUNCTIONS:



The mechanical and electrical characteristics as well as the performance of an electric generator
are a consequence of the magnetic circuit design. Because output results from the interaction
between current-carrying armature conductors, the air-gap flux and it is proportional to their
product, when designing the magnetic circuit WEG design provides the correct space for the windings
and the right path for the magnetic flux.




DESIGNING THE MAGNECTIC CIRCUIT:



The right design of the pole pitch and the number of poles assures always the best path for the
circuit. As the number of poles decreases, the restrictions in space available in the rotor
result in most of the magnetic circuit dimensions being a smaller proportion of the pole pitch.
The armature slot width is determined principally by the insulation thickness required for the
machine voltage and is commonly such that the resulting total copper width per slot is 40 to 60%
of the slot width.




MATERALS AND LOSSES:



To reduce Foucault currents caused by variations of the air gap flux density, and also to reduce
losses in the rotor pole faces, WEG selected the cylindrical type rotor instead of the high
stressed salient pole machines. Always when this type of pole is used we notice the air gap is
relatively large and the losses decrease to acceptable values. Most salient-pole machines on the
other hand, have smaller air gaps relative to the armature slot widths.



To improve the good characteristics of the cylindrical-pole configuration, our design also use
laminated poles. We can use one-piece laminations or segmental laminations, depending on the
machine size and the available widths of the electrical sheet of steel. Mostly WEG uses 3.5%
silicon electrical sheet steel in 0.014 to 0.025 in thickness. This sheets are stamped at WEG,
because quality and grain orientation. The correct finishing includes polishing and painting







 









 







of each individual sheet. During testing, when submitted to high flux densities the advantages of
this construction come to view in the general efficiency.




PERFORMANCE:



The field current required for a particular load condition is determined by the magnetic circuit
in conjunction with its armature and field windings. This is calculated during design by
evaluating the flux densities and the corresponding ampere-turns in all parts of the magnetic
circuit. After the machine is built, the magnetic characteristics are shown in the performance
report.




FRAME:



WEG’s electric generator’s frames are built entirely using steel sheets and MIG welded profiles.
It’s well known by its strength and mechanical resistance. It can be manufactured in many different
arrangements, and the most usual ones are B3 (with terminal boxes placed sideways) or D5 whose
characteristics include pedestal bearings and terminal box located at the bottom of the generator,
inside air outlet.




CLASSES OF INSULATION:



To assure long electrical/overall life, the temperature of operation should never surpass the
insulation class temperature of the materials used in the generator construction.



As result, the table below shows standard temperatures for the most common classes used for
this size of generators:




	 	 	 	 	 
	Insulation Class	 	Temperature Class	 	Temperature rise oC
	F
	 	155oC
	 	105oC max (or 80oC)






ARMATURE WINDING INSULATION:



As standard armature voltages can vary from 220 up to 18,000 V, it is necessary to ensure the
appropriate amounts of turn-turn and turn-ground insulation used to withstand different situations,
such as steady state or transients. In low voltage systems the turn-turn insulation may be applied
directly to the conductor as a film. In higher voltages it is necessary special methods to prevent
corona effects.



Despite of this recommendation, WEG assures all equipment here manufactured use the same
treatment, which consists in Vacuum and Pressure Impregnation.

After winded both stator and rotor are submitted to deep vacuum varnish impregnation (VPI),
which fills completely all existing remaining gaps. We use polyester varnish, and it assures an
insulation class F (or superior) with temperature class of 155oC (337oF).




COOLING SYSTEM:



Heat generated by internal losses must be exhausted to keep the internal temperature stable and
under standard values. Usually heat is transferred directly to air and this air can either be
cooled in a closed circuit by an outside water or air-cooling system (indirectly cooling system) or
can be exhausted (directly cooled system). In the first case, a closed circuit, there is no
possibility of debris formation on the coils, as it may occur in the second case.



WEG manufactures generators for both applications with a protection degree of IP-23 (open) or
IP-54/55/65 (closed).



Stators are frequently cooled by blowing air over the coil ends and through radial channels in the
armature core. The channels are normally in the range of 6 up to 8mm wide, with spacing between
each other of about 50mm, but they may be omitted entirely on machines with short core lengths.




MECHANICAL COMPARISON BETWEEN SALIENT POLE AND PLAIN POLE ROTORS:



The field configuration, salient pole and plain pole rotors distinguish two fundamental variations
in the mechanical construction. In most but the smallest modern alternators and in some ac brush
less exciters, the field is the rotating element, and the armature is the stationary element
(stator). Salient pole construction, where the field windings are on pole pieces attached to a
rotor body, is used on slower speed machines, 1200 rpm and lower, because of it’s relatively lower
cost. Plain pole construction, where the field windings are inserted in axial slots in a
cylindrical rotor body, is used on essentially all 2 poles and on the larger 4 pole machines,
because it minimizes the problems of fitting salient poles to the rotor body, which in such
high-speed machines become non-practical and too risky. The fundamentals of stator core and
winding construction for these two types of design are the same, but as far as the mechanical
behaviour and life expectancy is concerned the plain pole cylindrical rotor is superior.




BEARINGS:








 









 







Smaller AC generators can be furnished with ball anti-friction bearings when the load and speed
are not critical and operate very well as long as a preventative maintenance program is followed.



However, the majority of the AC generators are supplied with oil-lubricated babbitted
bearings. For horizontal shafts these are self-contained ring-oiled bearings when design
conditions permit.



At higher shaft peripheral speeds and higher bearing loadings ring-oiling is supplemented with
forced circulation of external cooled oil. The rings may be replaced by an external source, such as
the same lubricating system used by the turbine, or WEG can supply a self-sustained lubrication
system.



Lead base babbitted bearings are commonly used for journal bearings, although tin-base babbitt may
be employed in heavy-duty applications.



All bearings have an electrical connection to the ground to isolate electrical currents.




SPACE HEATERS:



To avoid water condensing inside generator, this equipment is built with an electrical resistance
that can be powered from any typical 240 VAC outlet. This way it can be stored for a long time,
as long as the heater is on.




BALANCING:



The standard mechanical balancing adopted by WEG is stated by ISO 1940, which defines the possible
grades, N (Normal), R (reduced) or S (special). Our Quality Control does not allow any rotor to
continue in the manufacturing process chain if it reached a degree above R 2,5 (Reduced).



For this reason we can assure a long reliable life, and low bearing wear, as well as no vibration
is transmitted to other related machines.




COATING:



All generators have its internal and external surface treated with steel debris blasting until
it reaches the cleanness degree Sa 2.1/2.



First coating is applied using polyamide epoxy 35 – 40 microns thick.



Finishing consists into two polyamide epoxy coatings, each one 70-80 microns thick, with
standard colour Medium Blue RAL 5007.







 









 







The coating process is designed to allow the machine to be installed in regular-aggressive acid
atmosphere with good resistance to alkaloids and humidity, typical for Sugar — Alcohol
distilleries, Paper, Wood or related industrial processes, etc...




QUALITY INSPECTION:



All Manufactured generators are factory thoroughly tested. There is a standard testing
procedure, and it is completed with no exceptions.



Special tests can be performed with or without witness/inspection, but it should be agreed between
buyer and seller before the PO is placed so it can be scheduled in advance. Any changes after that
may affect final price, delivery time, and the chronology established when the unit is being
manufactured. Such chronology is very important due to the available time in the testing lab, as
all products are tested, and some of them have a specific deadline to be followed.




ELECTRONIC/MICROPROCESSED VOLTAGE REGULATOR:



The main purpose of the voltage regulator is to keep a steady output voltage at any load condition.
It may include functions such as allowing synchronization with other generators and/or power
utilities, allowing power factor correction, and allowing reactive power compensation throughout
the capability curve.



WEG uses an electronic and high-speed micro processed voltage regulator in order to assure such
flexible operation.

IEC Recommendations



45.19 Limiting values for steam pressure and temperature 




Pressure variations



Average steam pressure at turbine throttle during a 12 months period shall not exceed the
nominal pressure



Maintaining the average value, the steam pressure shall not exceed 5% of nominal pressure;
however instantaneous peak values up to 20% are allowed provided that the total duration of
peak loads shall not exceed 12 hours in a period of 12 months of operation.




Temperature variation



Temperature shall never exceed 8oC above the normal operating temperature. Under exceptional
circumstances the steam temperature can exceed 14oC above the operating temperature, provided that
these conditions do not exceed 400 hours in a period of 12 months of operation.




Steam line 



In order to assure a good performance of the turbine and prevent damages the steam conditions
shall remain within the limits stated above and the steam shall be free of condensate.







 









 







Condensate in the steam line may produce thermal shocks with severe consequences and
serious damages, for instance shaft distortion.

These values are valid only for mineral oil.






 




			
	(+)	 	When active substances are used the above values are higher.





Recommended quality for cooling water



The materials selection for steam condenser and heat exchanger is directly related to the type
of cooling water used (aggressiveness). It becomes clear that water aggressiveness in continuous
operation should not increase in relation to the value originally specified, because it may reduce
significantly the average lifetime of the equipment.



Besides, deposits on the tubes decrease the heat exchange efficiency and speed up internal
corrosions.



In order to assure safe operation, some basic requirements have to be followed, as indicated below:




Open circuit cooling



The total amount of salt shall not exceed 100 mg/l. Water shall have adequate chemical composition
because treatments are not applicable.



In case of particles in suspension, filtering must be applied. Seaweed can be eliminated by
clorification. To avoid separation of carbonates, it’s necessary to keep the balance of the
calcium/carbonic acid rate.




Closed circuit cooling



The following figures shall be kept:





 









 








	 	 	 

	PH
	 	7
	Carbonic acid
	 	3 g/l
	Carbonate hardness
	 	6°dH
	Carbonate hardness for polymorph phosphates
	 	12°dH
	Non-carbonate hardness
	 	80°dH
	Clorets
	 	400 mg/l
	Sulfates
	 	500 mg/l
	Total salt
	 	3000 mg/l
	Total alkalinity
	 	15 mgl/l
	Silic acid
	 	200 mg/l
	Particles in suspension
	 	10 mg/l





Note: Water flow shall be periodically inspected. The water chambers must be always clean.
