License approved for Los Angeles area power plant

SACRAMENTO --The California Energy Commission today approved a license for the construction of the 500-megawatt Walnut Creek Energy Park in Los Angeles County.

By a vote of 4-0, the Commission accepted the Presiding Member's Proposed Decision (PMPD) recommending approval of the simple-cycle power plant designed as a peaking facility to meet electric generation load during periods of high demand.

The facility, expected to cost between $220 million and $280 million will be located on an 11.48-acre site in the City of Industry. It was licensed after the owner, Walnut Creek Energy, LLC, a wholly owned subsidiary of Edison Mission Energy, said it would comply with applicable laws, ordinances and regulations by satisfying requirements spelled out in the PMPD.

According to the PMPD, the owner will have to minimize air emissions by using the best available control technology and fully offset pollution impacts from the project based on the revised Rule 1309.1 of the South Coast Air Quality Management District (SCAQMD). The rule allows the plant to purchase pollution-offset credits from the air district's Priority Reserve for bio-energy plants and new and expanding power plants.

Furthermore, if the plant has to be fired up at night, Walnut Creek Energy LLC, will have to limit operations to render the plant barely audible (at 49 dBA on the decibel sound pressure scale).

Construction of the facility, located 22 miles east of downtown L.A. is expected to begin in the summer of 2008 and would continue through January 2009. Targeted on-line date is summer of 2009. The plant would connect with Southern California Edison's electrical system at the nearby existing Walnut Substation.

Since deregulation occurred in 1998, the Energy Commission has licensed or given small power plant exemptions to 65 power plants, totaling 24,566) MW. Thirty-eight licensed power plants are in operation, producing 13,087 MW. Since Gov. Schwarzenegger took office, 20 of these power plants, totaling 7,530 MW have been approved. In addition, 18 power plant projects are active in the Energy Commission's review process, representing 7,451 MW.
