Larkspur Energy Facility
Emergency Peaker Project

Docket Number:

01-EP-01 (Application For Certification)
01-EP-01C (Compliance Proceeding)

Project Status: Licensed; In Compliance Phase. Operational: July 16, 2001

Applicant: Wildflower Energy LLP / InterGen

Location: San Diego, California

Size: 90 Megawatt Peaking Power Plant


Wildflower Energy LP proposes to construct the Larkspur Energy Facility (LEF), a simple-cycle, dual fueled peaking electric generation facility consisting of two GE LM6000 gas turbine engines generating 90 MW. The LEF will be located at the corner of Harvest Road and Otay Mesa Road located in the City of San Diego, in San Diego County.

The facility will connect to the existing San Diego Gas & Electric substation adjacent to the site via a new 500 foot 69 kV overhead transmission line. Natural gas will be supplied to the facility via a new 500 foot 12-inch diameter interconnection to the existing SDG&E 36-inch natural gas line adjacent to the site.

During periods of natural gas curtailment, the facility will operate on diesel fuel oil. The Larkspur project will incorporate selective catalytic reduction (SCR) to reduce project emissions. NOx emissions, when operating with natural gas, are 5 ppm. NOx emission during curtailment periods are 42 ppm.

The facility will consume approximately 320 gallons/minute of water, peak, supplied via an interconection with the existing Otay Water District line adjacent to the project. Waste water from the project will be discharged to the existing San Diego Metropolitan Wastewater District system sewer lines adjacent to the site. Hazardous materials required and stored onsite for the project are aqueous ammonia and diesel fuel oil.

The project is expected to be in operation by June 1, 2001. The construction will take approximately 2.5 months and will begin upon Commission approval of the project.

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.
