REDWOOD CITY, CA – Sept. 7, 2021 – Peninsula Clean Energy will receive clean and reliable electricity generation from the world’s largest complex of geothermal power plants.

Peninsula Clean Energy beginning in July 2022 will receive 35 megawatts (MW) of geothermal power from The Geysers, a 725-MW complex run by Calpine Corporation and located 70 miles north of San Francisco. The power purchase agreement is Peninsula Clean Energy’s first to involve geothermal. The 35 MW are enough to power 60,000 households annually in San Mateo County.

“The geothermal power from The Geysers is another reliable tool to reduce heat-trapping greenhouse gas emissions and slow climate change,” Peninsula Clean Energy CEO Jan Pepper said. “This helps us further evolve our energy mix to meet growing demand for affordable 24/7 renewable power.”

The 15 geothermal power plants at The Geysers stretch across 45 square miles in Sonoma and Lake Counties and are responsible for providing nearly one-tenth of the renewable power produced annually in California.

“Calpine and The Geysers are proud to support Peninsula Clean Energy in its goal of providing clean, renewable and reliable energy to customers across San Mateo County and the city of Los Banos,” said Gevan Reeves, Calpine’s Vice President of Origination. “Geothermal energy from The Geysers is available every hour of every day, supporting Peninsula Clean Energy’s efforts to deliver a reliable power portfolio sourced from 100 percent renewable energy. It also supports hundreds of hardworking employees committed to powering communities across California with reliable geothermal energy.”

The geothermal power from The Geysers will bring Peninsula Clean Energy another step toward the organization’s ultimate goal of providing 24/7 renewable power to its customers. Peninsula Clean Energy this year for the first time began providing 100 percent carbon-free power to all of its nearly 300,000 customers. At least half of that power this year stems from renewable power, with the remainder coming from large hydropower and other carbon-free generation.
