"As California's electricity demand continues to grow, investments in reliable, around-the-clock renewable energy are more important than ever," said Aimee Blaine, senior vice president of Calpine's geothermal region. "The Geysers is one of the nation's most important geothermal resources, and this expansion reflects our commitment to strengthening grid reliability while advancing California's clean energy goals."
For over 65 years, The Geysers has provided clean, geothermal energy across California. Of the 25 MW expansion, 18 MW will be directed to Clean Power Alliance (CPA), which serves customers across Southern California, providing reliable, around-the-clock renewable power as demand for clean electricity continues to grow. The remaining 7 MW, which were brought online last year, are being supplied to MCE to support Bay Area residents and businesses.
"Clean Power Alliance is committed to delivering dependable clean energy to our customers, and geothermal power plays an important role in providing around-the-clock renewable electricity," said Matthew Langer, chief operating officer, Clean Power Alliance. "Partnerships like this strengthen California's clean energy future while supporting a more resilient and sustainable grid."
The recent expansion was completed under a Project Labor Agreement (PLA) with local labor unions to build critical piping infrastructure, ensuring the work was completed by a highly skilled craft workforce under strong labor standards.
The Geysers is the world's largest operating geothermal complex, generating electricity by tapping natural steam reservoirs deep beneath the earth's surface. Geothermal energy provides an inherent environmental advantage and helps meet California's clean air goals. Geothermal power operates continuously regardless of weather or time of day, making it a critical source of baseload clean energy.
