Ormat Technologies, a company specializing in geothermal and renewable energy, has secured a 25-year extension of its power purchase agreement (PPA) with the Southern California Public Power Authority (SCPPA). The agreement involves supplying 52MW of clean energy from the Heber 1 geothermal facility, located in the Imperial Valley of Southern California. The extension, effective from February 2026, will run through 2052, ensuring a steady supply of renewable energy to the Los Angeles Department of Water and Power (LADWP) and the Imperial Irrigation District.

Heber 1 is located in Imperial Valley, Southern California.

The Heber 1 facility, a key component of Ormat’s operations, has been upgraded with modern air-cooled technology through a recent repowering project. Together with the broader Heber complex, it generates 91MW of continuous, carbon-free electricity, serving millions of California residents. This reliable energy source supports the region’s push for sustainable power and reduced dependence on fossil fuels.

Ormat Technologies CEO Doron Blachar stated: “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.”

The extended PPA aligns with California’s efforts to diversify its energy portfolio and enhance grid reliability. The Heber 1 plant is expected to provide electricity to over 77,000 households in Los Angeles, contributing to a more sustainable energy future. LADWP Power System senior assistant general manager David Hanson stated: “Our commitment to renewable energy is rooted in building a more resilient, sustainable future for Los Angeles. 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 LA 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.”

This agreement highlights the growing importance of geothermal energy in meeting clean energy needs. By utilizing advanced technology and fostering long-term partnerships, Ormat Technologies supports California’s goals of ensuring a stable, eco-friendly power supply. The Heber 1 facility’s role in delivering consistent, renewable energy underscores its value in advancing both environmental sustainability and energy security for the region.
