The proposed BEC project would be a 200 megawatts (MW) simple-cycle power plant located in the City of Fresno. The BEC is designed as a peaking facility to meet electric generation load during periods of high demand, generally during summer daytime hours. The applicant has a 20-year contract with Pacific Gas & Electric (PG&E) as a result of the 2004 PG&E Request for Offers for new generation resources.
The proposed 12.3-acre BEC site is located at 5829 North Golden State Boulevard, in the City of Fresno. This parcel is zoned M-1 (light industrial use) and is located in an industrial area. A truck depot, and construction equipment fabrication and storage yard are currently located on this site. There would also be a temporary construction laydown and parking site on a 9.2-acre parcel located immediately to the north of the plant site.
The generating facility will include two General Electric (GE) LMS100 natural gas-fired combustion turbine generators (CTGs), inlet air filters with evaporative coolers, a turbine compressor section inter-cooler, a mechanical draft cooling tower, circulating water pumps, water treatment equipment, natural gas compressors, generator step-up and auxiliary transformers, and a water storage tank.
A new 230 kV looping substation will be constructed on-site, tying into the east side of the existing PG&E Herndon-Kearney 230 kV line, which runs across the southwest corner of the site. Approximately two miles of the existing 230 kV transmission line will require re-conductoring.
The project will connect to a PG&E natural gas pipeline approximately 9,500 feet west of the site. The primary pipeline route will convey gas via a new pipeline up to 12 inches in diameter along West Bullard Avenue to North Golden State Boulevard, and then south to the site. Two alternate routes involve the same PG&E gas connection location, running north along North Garfield Avenue to Herndon Avenue, then south along North Golden State Boulevard and North Weber Street to the site.
BEC process water consumption would be for combustion turbine water injection, cooling tower makeup, inlet evaporative cooler makeup, and plant service water. A maximum of 671 acre-feet would be provided by the City of Fresno from a water main located near the southeast corner of the site along North Golden State Boulevard will be extended approximately 300 feet, to the northeast corner of the site.
Wastewaters from the project will consist of cooling tower blowdown and process water treatment residue. Wastewater will be conveyed for treatment to the City of Fresno sewer system via a new 14-inch diameter, 1,500-foot sewer line along North Golden State Boulevard.
Air emissions from the proposed facility would be controlled using best available control technology. The two combustion turbine generators will be equipped with water injection to the combustors for reducing production of oxides of nitrogen (NOx), a selective catalytic reduction system with ammonia injection to further reduce NOx emissions and an oxidation catalyst to reduce carbon monoxide emissions. The San Joaquin Valley Air Pollution Control District will conduct a New Source Review and provide the Energy Commission with a Determination of Compliance reviewing the proposed project's compliance with District rules and regulations.
If licensed, project construction would start in 2008, and commercial operation planned by summer 2009.
