1 Introduction

The latest series of baseline reports prepared for NETL was begun in 2004, and the report 

commonly referred to as the Bituminous Baseline Report (“Cost and Performance Baseline for 

Fossil Energy Plants, Volume 1: Bituminous Coal and Natural Gas to Electricity”) was first 

published in May 2007. The initial issue of the Bituminous Baseline Report used a cost basis of 

January 2007 dollars. The report was subsequently updated in August 2007 and again in 

November 2010. The cost basis was updated to June 2007 dollars in the November 2010 issue. 

Recently, the capital and O&M costs for selected cases were re-estimated using a cost basis of 

June 2011 dollars. The eight cases that are the subject of this report include:

• Case 1 – GEE IGCC without CO2 capture

• Case 2 – GEE IGCC with CO2 capture

• Case 9 – Subcritical PC without CO2 capture

• Case 10 – Subcritical PC with CO2 capture

• Case 11 – Supercritical PC without CO2 capture

• Case 12 – Supercritical PC with CO2 capture

• Case 13 – Natural gas combined cycle without CO2 capture

• Case 14 – Natural gas combined cycle with CO2 capture

The Total Overnight Cost (TOC) and first year Cost of Electricity (COE) are summarized in 

Exhibit 1-1. The previous values (2007 dollar cost basis) are included for reference and the 

values with and without CO2 sequestration costs are shown for the capture cases. The difference 

in sequestration costs reflects a change in methodology in addition to the escalation incurred 

from 2007 to 2011. The new approach is described in more detail below.

The increase in TOC from 2007 to 2011 averaged about 20 percent. The COE for the coal cases 

increased approximately 37 percent. The increase in COE for the natural gas cases was small 

since the increase in COE associated with the increased TOC was nearly offset by a fuel cost 

reduction.

2 Cost Escalation Factors

Escalation factors for the various cost elements were developed using a number of sources 

including: the Chemical Engineering (CE) Plant Cost Index, recent vendor quotations for similar 

equipment and materials, monthly mill pricing updates for structural steel, cost trending input 

from vendors, and published wage rate information. In general the CE Index tends to trend 

slightly lower than costs developed using other sources. This can be due to several reasons 

including specific equipment design/sizing parameters and market conditions. In particular the 

index value for construction labor and engineering services was not used here because it almost 

always trends at a much lower rate than other sources employed. The resulting escalation 

averaged about 20 percent across accounts with modest variations caused by the distribution of 

labor, materials and equipment costs as well as the equipment type.

Equipment accounts that don’t follow the general cost escalation trend are described below:

• Case 1, Account 4.6 (Soot Recovery & SARU): The original estimate (2007 dollars) had 

an incorrect value that was fixed prior to escalating the account making the escalation 

appear to be greater than reality.

• Cases 1 and 2, Account 5A.6 (Blowback Gas Systems): The GEE gasifier does not use 

candle filters and therefore no blowback gas system is required. This account was 

inadvertently included in the previous estimate, but has been eliminated in the current 

version.

• Cases 1, 2, 13 and 14, Account 7.1 (Heat Recovery Steam Generator): The HRSG costs 

were re-calibrated using a series of more recent quotes that were also closer in size to the 

baseline cases.

• Cases 1, 2, 13 and 14, Account 8.3 (Condenser and Auxiliaries): The condenser costs 

were re-calibrated using a series of more recent quotes that were also closer in size to the 

baseline cases.

• Cases 1, 2, 13 and 14, Account 8.4 (Steam Piping): The steam piping costs were recalibrated using a series of more recent quotes that were also closer in size to the baseline 

cases.

• Cases 1, 2, 13 and 14, Account 9.1 (Cooling Towers): The cooling tower costs were recalibrated using a series of more recent quotes that were also closer in size to the baseline 

cases.

• Cases 1 and 2: The consumables were generally escalated using the index for producer 

prices for industrial chemicals (per IHS Global Insight, Inc., and reported in Chemical 

Engineering). However, the Selexol solvent cost also included revised pricing from more 

recent quotes.

• Cases 9, 10, 11, 12, 13 and 14: The consumables were generally escalated using the index 

for producer prices for industrial chemicals (per IHS Global Insight, Inc., and reported in 

Chemical Engineering). However, the ammonia cost also included revised pricing from 

more recent quotes.
Updated Costs (J une 2011 Basis)

• Cases 2, 10, 12 and 14, Account 5B.1 (CO2 Compression and Drying): The CO2

compressor costs were re-calibrated using a more recent quote in addition to the general 

cost escalation.

• All Cases, Account 11.8 (Main Power Transformers): The main power transformer cost 

was re-calibrated using a more recent quote in addition to the general cost escalation.

In the PC cases the boiler and steam turbine costs were simply escalated because no newer 

quotes were available.

3 Updated Transport and Storage Cost Methodology

The cost of CO2 transport and storage (T&S) in a deep well saline formation is estimated using 

the FE/NETL CO2 Transport and Storage (CTS-Saline) Cost Model. Additional detail on 

development of these costs is available in the Quality Guidelines for Energy System Studies 

(QGESS) on Carbon Dioxide Transport and Storage Costs in NETL Studies (2012).

T&S costs are reported as first-year costs in $/tonne of CO2, increasing at a nominal rate of 3 

percent per year, consistent with the assumed general inflation rate. From the perspective of the 

CO2 source (e.g., a power plant or other energy conversion facility), these costs are treated as a 

disposal cost for each tonne of CO2 captured during the assumed 30-year operational period. 

From the pipeline and storage site’s perspective, this cost represents the required revenue stream 

across the 30-year operational period to cover all costs and provide the required internal rate of 

return on equity (IRROE). All costs are reported in 2011 dollars.

Transport costs are based on a generic 100 km (62 mi) dedicated pipeline. High pressure (2,200 

psig) CO2 is provided at the plant gate of the energy conversion facility and CO2 exits the 

pipeline terminus at a pressure of 1,200 psig, remaining in a supercritical phase. The pipeline 

diameter was sized for this to be achieved without the need for recompression stages along the 

pipeline length. Costs for additional compression that may be required for injection in a 

particular formation is included as part of storage costs. Transport costs are estimated to be 

$3.65/tonne CO2.

Storage costs are based on the CTS-Saline Cost Model. This model provides detailed cost 

estimates for the injection and monitoring of CO2 under U.S. Environmental Protection Agency 

regulations for Class VI injection wells as well as monitoring and reporting requirements under 

Subpart RR of the Greenhouse Gas Reporting Rule. 

Inputs to the CTS-Saline Cost Model that have a significant influence on cost include financial 

parameters, the timelines for the various stages of storage and important activities occurring in 

each stage. The financial parameters include:

• Debt to equity ratio: 45%/55%

• Nominal interest rate on debt: 5.5%/year

• Nominal IRROE: 12%

• Escalation rate: 3%

• Financial responsibility requirements for post-injection site care and site closure are met 

by pre-funding a modified trust fund over the period of injection operations

• Project contingency factor of 15% and process contingency factor of 20%

In the CTS-Saline Cost Model, the sequestration process is divided into six stages. The timelines 

and important activities impacting costs for these stages are as follows:

• Regional evaluation and initial site selection: 1 year

• Site characterization: 3 years; four sites undergo site characterization with one successful 

site selected; pore space rights are leased

• Permitting: 2 years; drill, test and complete injection wells
Updated Costs (J une 2011 Basis)

6

• Operations: 30 years; installation of buildings, surface equipment, monitoring wells and 

other monitoring equipment; comply with permit requirements; fund modified trust fund 

to cover financial responsibility requirements for post-injection site care and site closure

• Post-injection site care and site closure: 50 years; continue monitoring, verification and 

accounting (MVA) per permit; costs are covered by storage site operator’s trust fund

• Long-term stewardship: (This stage is not explicitly included in the model.) The possible 

financial implication of long-term stewardship is included in the model as a statesponsored trust fund that the storage operator pays into during operations

Due to the variances in the geologic formations that make up saline formations across the U.S., 

region-specific storage and monitoring costs are developed to correspond to the plant locations 

used in NETL techno-economic studies of energy conversion facilities. Results from the CTSSaline Cost Model for storage and monitoring costs were aligned with the NETL studies by 

taking four generic plant locations and overlaying them with possible sequestration basins from 

the cost model resulting in the following pairings:

• Midwest plant location – Illinois Basin

• Texas plant location – East Texas Basin

• North Dakota plant location – Williston Basin

• Montana plant location – Powder River Basin

CO2 storage supply-cost curves were developed for each of the four basins of interest with the 

resulting cost for each basin at 25 gigatonnes (Gt) of potential storage shown in Exhibit 3-1. 

Choosing this point on the supply-cost curves provides a conservative estimate of the storage 

cost since many decades, if not more than a century, will pass before 25 Gt of CO2 is stored in 

any of the four individual basins. For example, 25 Gt of storage would be sufficient for 125 GW 

of coal power with 90 percent CO2 capture operating over 30 years. 

The far right column of Exhibit 3-1 shows the total T&S costs now used in NETL system studies 

for each plant location.

4 Capital and O&M Cost Tables

The updated capital cost and O&M cost tables are contained in this section. In addition to the 

capital cost escalation, the following updates were included:

• Fuel costs were updated to June 2011 values according to the Quality Guidelines for 

Energy System Studies, “Fuel Prices for Selected Feedstocks in NETL Studies.” The 

current fuel costs are $2.94/MMBtu for Illinois No. 6 bituminous coal and $6.13/MMBtu 

for natural gas in the Midwest.

• The CO2 transport and storage (T&S) costs were estimated at $10/tonne CO2 sequestered. 

This value is representative of a Midwest location as described in Section 3.

A table comparing the change in unit cost of fuel and major consumables is shown in Exhibit 

4-1.

5 Summary of Results

The TOC, COE, CO2 capture, and CO2 avoided costs are summarized in Exhibit 5-1 for Cases 1, 

2, 9, 10, 11, 12, 13 and 14. The previous values (2007 dollar cost basis) are included for 

reference and the values with and without T&S are shown for the capture cases. The difference 

in T&S costs reflects the change in methodology and is currently based on a value of $10/tonne 

CO2.

The 2011 COE by cost component is shown in Exhibit 5-2. The COE increase from 2007 to 

2011 averages 37 percent for the coal based technologies and 3 percent for the two natural gas 

based technologies. The cost differences are attributed to the following:

• An increase in the capital component of COE of 20-24 percent for all technologies and 

fuel types.

• An increase in the fixed O&M cost component of COE of approximately 20 percent for 

all technologies and fuel types. Labor costs increased by about 15 percent, and the fixed 

O&M costs are also strongly aligned with the capital costs, thus the similar increase.

• An increase in the variable O&M cost component of 28-35 percent for the IGCC and 

NGCC cases and 52-55 percent for the PC cases. The higher PC variable O&M cost 

increase is due primarily to the large increase in ammonia unit cost relative to 2007 (a 

factor of 2.5).

• An increase in the fuel component of COE of 80 percent for the coal based cases and a 

decrease of 3 percent for natural gas based cases.

• An increase in the T&S component of COE of 62-86 percent for coal-based capture cases 

and 20 percent for the natural gas based capture case. The differences result from 

escalation and the new T&S methodology that assumes a cost of $10/tonne CO2.

The decrease in fuel cost largely offsets the increase in the other COE components for the NGCC 

cases, resulting in only a small increase in the 2011 COE. The large increase in coal cost adds to 

the other COE cost component increases, resulting in the 30-40 percent increase in the 2011 

COE.

The CO2 capture and avoided costs are shown in Exhibit 5-3 for each of the capture cases. The 

CO2 capture cost and the avoided cost using the analogous technology as the reference case both 

reflect the relative increases in COE of the non-capture and capture cases from 2007 to 2011. To 

illustrate, the cost difference between the IGCC capture and non-capture cases in 2007 dollars 

was $29.29/MWh and in 2011 dollars was $40.32/MWh. This 38 percent increase in cost 

differential is reflected in the 38 percent increase in CO2 capture and avoided (analogous 

technology reference case). The cost of CO2 avoided using the SC PC non-capture reference 

case exhibits a similar trend except for the NGCC capture case. The SC PC non-capture 

reference case experienced a nearly 40 percent COE increase from 2007 to 2011 dollars, but the 

NGCC capture case experienced only a 4 percent increase (mostly due to the lower fuel cost). 

The result is a significantly lower cost of CO2 avoided ($12/tonne) for NGCC when comparing 

to the SC PC non-capture reference.
