Project Status: Licensed; In Compliance Phase. Operational:
July 26, 2001
September 1, 2001



Applicant: Wildflower Energy LLP / InterGen

Location: Palm Springs, California

Size: 135 Megawatt Peaking Power Plant



GENERAL DESCRIPTION OF PROJECT

Wildflower Energy LP proposes to construct the Indigo Energy Facility, a nominal 135 MW simple-cycle natural gas power plant, to be located at approximately one-half mile northwest of the Indian Avenue interchange with I-10 in the City of Palm Springs in Riverside County. The facility will connect to the 115 kV transmission line that runs between the Garnet and Devers substations. The project will include a new 24-inch natural gas supply line that will connect to one of the existing 30-inch Southern California Gas Company main 30-inch pipelines south of I-10.

The project will utilize Selective Catalytic Reduction (SCR) and CO oxidation catalyst systems to control emissions of oxides of nitrogen (NOx) and carbon monoxide (CO). The project will obtain water from the Mission Springs Water District, which has a 12-inch water main that runs along the south side of the project site. Peak water usage is estimated at 240 gallons per minute. The only wastewater discharge from the facility will be storm drainage, which will be routed to an oil-water separator prior to discharge into the local storm drainage system. The project will use aqueous ammonia for the SCR system. The ammonia will be stored in three 10,000 gallon tanks with secondary containment.

Wildflower anticipates construction to take two to three months. This schedule is dependent on timely completion of the natural gas and transmission interconnections. The peak construction workforce will be approximately 200.


Energy Commission Facility Certification Process

The California Energy Commission is the lead agency (for licensing thermal power plants 50 megawatts and larger) under the California Environmental Quality Act (CEQA) and has a certified regulatory program under CEQA. Under its certified program, the Energy Commission is exempt from having to prepare an environmental impact report. Its certified program, however, does require environmental analysis of the project, including an analysis of alternatives and mitigation measures to minimize any significant adverse effect the project may have on the environment.
