The Board of Imperial County has approved Ormat's proposed 25-MW Dogwood geothermal power project, located in the Heber 2 geothermal complex in California.
The Imperial County Board of Supervisors in California has approved the proposal by Ormat Technologies Inc. (Ormat) for the Dogwood Geothermal Energy Project, to be located within the existing Heber 2 Geothermal Energy Complex (HGEC). Ormat applied for three conditional use permits (CUPs) which were unanimously approved by the board, along with the corresponding environmental impact report and mitigation requirements.
The three CUPs cover the following:
- One 25-MW (net) integrated two-level unit air-cooled Ormat Energy Converter (OEC) generating unit
- Two 20,000 gallon isopentane tanks
- One substation
- Ancilly and auxiliary facilities
- One 7-MW solar photovoltaic facility (to supply parasitic load to the Dogwood geothermal plant)
- Medium voltage distribution cable from the Dogwood solar facility to the Dogwood geothermal plant
- One 15-MW solar PV facility dedicated to the Heber 2 geothermal plant
- Three geothermal production wells, one reinjection well, and brine pipelines
The HGEC includes the Heber 2, Heber South, and Goulds 2 geothermal energy facilities. It is operated by the Second Imperial Geothermal Company, a subsidiary of Ormat.
In 2022, Ormat signed a 15-year power purchase agreement (PPA) with community choice aggregator Peninsula Clean Energy for 26 MW of power from the Heber 2 geothermal facility.
