Operational: July 16, 2001

Applicant: Wildflower Energy

Location: San Diego, San Diego County

Size: 90 Megawatt Peaking Power Plant

Key Dates

  • 3/8/2001 - Small Power Plant Exemption (EP) filed
  • 3/16/2001 - Commission accepts EP as "data adequate."
  • 4/4/2001 - Commission approves Small Power Plant Exemption.

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.

Small Power Plant Exemption Evaluation Process

The SPPE process allows projects between 50 and 100 MW to proceed with local approval rather than requiring an Energy Commission license. This exemption from the Energy Commission licensing process can be applied to projects that would not create a substantial adverse impact on the environment or energy resources. The Energy Commission acts as the lead agency under the California Environmental Quality Act (CEQA) and will prepare an Initial Study and Mitigated Negative Declaration that examines public health and safety, along with environmental impacts of the proposed project, including all related facilities such as electric transmission lines, natural gas and water pipelines. If the exemption is granted, the applicant would still need to secure the appropriate licenses and permits from relevant local, state, and federal agencies.
