California-based community choice power aggregator Peninsula Clean Energy on Tuesday said that it has signed four contracts to procure electricity from close to 68 MW of renewables for a round-the-clock supply to its customers in San Mateo County and the City of Los Banos.
The contracts originate from a November 2021 solicitation and are part of 70 project proposals that Peninsula Clean Energy received on the occasion, the not-for-profit aggregation agency said.
The scope of the procurement covers the power supply from Nova III, a 50-MW standalone battery storage system developed by Calpine Corporation, 6 MW of geothermal power from the Whitegrass No. 2 project developed by Open Mountain Energy, 3 MW from the Burney Creek small hydroelectric project and close to 9 MW from the Wind Resource 1 wind farm developed by CalWind.
The duration of the contracts ranges from three years for the wind power and 20 years for the Whitegrass No. 2 geothermal power plant. The Whitegrass project is the only one located in Nevada, while the others are in California.
Additionally, Ormat Technologies Inc (NYSE:ORA) started feeding electricity from its 26-MW Heber 2 geothermal power plant in California’s Imperial Valley in January, the agency said. Peninsula Clean Energy last year signed a 15-year power purchase agreement (PPA) to procure this plant’s entire output.
“These projects will help Peninsula Clean Energy meet its goal of matching renewable power supply with customer power demand on an hourly basis,” said Peninsula Clean Energy CEO Jan Pepper. “This is not only our top priority as an agency but also allows us to take the lead among all utilities in demonstrating that it is possible to provide hourly renewable energy in a cost-effective way.”
