## Costs

| Engineering Costs | $9,700 |
| --- | --- |
| Permitting Costs | $300 |
| Microturbine | $80,000 |
| Fluid Cooler | $5,000 |
| Construction Cost | $70,000 |
| Electrical Interconnection Cost | $500 |
| Gas Interconnection Cost | $5,200 |
| Heat Exchanger | $16,000 |
| Misc Costs | $27,300 |
| Total Costs | $214,000 |

## Costs Continued

- Previous owner spent an estimated $214,000 dollars on installation costs.
- A significant amount of this cost was spent on “learning the business.”
- There were change orders and costs associated with correcting design oversights.

## Costs Continued

**100% Hindsight**
- More attention to the thermal load than the electrical load
- Application must be able to use most of the heat
- Size of hot water loop must be considered for thermal reaction time
- Applications may not be “plug-n-play”
- Proper engineering on the front end is an absolute must

## Cost Continued

**50****th**** Installation**
- Standardize fleet of generators being used
- Standardize the type of pumps, valves, heat exchangers and so on
- Build off of previous engineering experience to reduce engineering costs

## Electrical Performance

- Hours of operation to December 31, 2002 is 9,800 hours.
- Average Electrical Performance is approximately 23% (Net).
- Electrical Power delivered to load is 78kW.
- Parasitic Losses are 5.5kW.
- Power Quality is approximately 2.0% or less THD per phase.

## Improvements

- VFD used to replace the thermal switch control on the dump radiator
- Circulation pumps added to both laundry and domestic hot water loops to improve waste heat recovery.

## Thermal Performance

- Measured maximum of 450 kBTU/hr (maximum heat from microturbine is 500 kBTU/hr).
- The site consumes an average of 375 kBTU/hr.
- Delta T across heat exchangers is 10 to 20 degrees F.  This varies as a function of site usage.
- Average Thermal Efficiency is measured at 44%.
- Expected Peak Total System Efficiency (Electrical + Thermal) is 75%.

## O&M Performance

- Availability is 85.28%
- Average number of hours the unit is down per month is 7 hours.
- Annual O&M costs are difficult to estimate outside of the warranty.  Annual PM costs are estimated at $3,000 annually.
- Unscheduled failures can impact O&M costs significantly.  Spare part availability and cost are current industry issues.

## Institutional Experience

- Site developed by Sempra Energy Connections.
- Permitting issues can cause the project to slip schedule.
- CARB (California Air Resources Board) requirements for January 1, 2003 compliance is an issue in the California market.
- The electrical interconnection has not been an issue to date.

## Supplier Support

- Bowman Power’s Technical Support is very good.
- Trained Distributor Technical Support is still developing.
- Spare parts availability is an issue in their availability to have parts shipped from the manufacturer to the end user.  (There is a limited stock of spare parts locally.)

## Supplier Support Continued

- Bowman has performed very well in supporting and resolving all warranty issues.

## General Experience

- Improvements for future installations:
- Packaging for smaller footprints
- Integrating the fuel gas compressor into the package
- UL certification
- CARB certification

## General Experience Continued

**Future market development will be driven by economics.**
- Existing transmission grid is heavily loaded. Distributed generation can relieve a portion of this loading.
- Lowered installation and maintenance costs.
**R&D or development should continue to support complimentary technologies.**
- Absorption Chilling
