Ormat Technologies on Aug. 25 announced that it signed a 25-year extension to its existing power purchase agreement with the Southern California Public Power Authority for 52 megawatts from the Heber 1 geothermal facility.
This long-term agreement, which is effective February 2026, will ensure the continued delivery of clean, baseload geothermal energy to the Los Angeles Department of Water and Power and the Imperial Irrigation District, both of which are SCPPA members.
Ormat will supply the SCPPA with electricity from the Ormat Heber 1 geothermal facility, located in the Imperial Valley of Southern California.
“This previously announced agreement has now received the required approvals, which demonstrates both the promise of geothermal energy and Ormat’s ability to deliver reliable, renewable power at scale,” said Doron Blachar, Chief Executive Officer of Ormat Technologies. “We are proud to extend our partnership with SCPPA, LADWP, and IID in order to continue supporting California’s climate leadership and ambitious climate and energy transition goals through our Heber 1 geothermal facility.”
The Heber 1 power plant, one of Ormat’s flagship geothermal assets, has been a cornerstone of clean energy supply in Southern California for decades, the company said.
Now operating with the latest air-cooled technology following its successful repowering project, the power plant, together with the entire Heber complex, delivers 91MW of carbon-free, around-the-clock electricity. This extension now ensures that the Heber 1 power plant will continue serving millions of California residents through 2052.
“IID continues to be a longtime, strong supporter of renewable energy development in the Imperial Valley for the clean power it provides, and we fully support Ormat’s work to continue this,” said Gina Dockstader, IID Board Chairwoman. “We sincerely appreciate the extended agreement with our partners for this reliable source of power.”
“This agreement ensures SCPPA Members can continue delivering reliable, affordable, and carbon-free energy to our communities, while advancing California’s clean energy goals,” said Daniel Garcia, Executive Director, Southern California Public Power Authority, on behalf of the Members and Board of Directors.
“Our commitment to renewable energy is rooted in building a more resilient, sustainable future for Los Angeles,” said David Hanson, LADWP’s Senior Assistant General Manager of Power System. “Geothermal energy plays an important role in that future—providing safe, reliable power that strengthens grid stability and reduces our dependence on fossil fuels. The Heber 1 power plant is expected to supply power to more than 77,000 L.A. households – an added step in diversifying our clean energy portfolio. Investing in geothermal energy is not just about meeting climate goals; it’s a strategic decision that supports long-term energy security and environmental stewardship.”
