Calpine Corporation this week marked the 65th anniversary of The Geysers, one of the world's largest and most productive geothermal energy sites.
The milestone reflects more than six decades of innovation, partnership and sustainable power generation in Northern California, the company said in a media release.
Calpine Corporation is America's largest generator of electricity from natural gas and geothermal resources with operations in competitive power markets.
Since commercial operations began in 1960, The Geysers has been at the forefront of California's energy transformation, producing reliable, around-the-clock renewable power using steam heated by the Earth's core.
Today, Calpine's 13 geothermal power plants across the 45-square-mile terrain generate enough renewable electricity to power approximately 725,000 homes annually.
“The success of The Geysers over the past 65 years is a testament to the people who have cared for it: hardworking, committed individuals who view stewardship as both a duty and a privilege,” said Aimee Blaine, Calpine's Senior Vice President, Geothermal Region.
Calpine has nearly 300 employees and 150 contractors who live and work in Lake and Sonoma Counties, who have helped make The Geysers a “global model for responsible geothermal development” and a cornerstone of California's renewable energy portfolio, the company stated.
“Together with our partners and community, we have built a deep connection to each other and this land,” said Blaine.
“Our shared pride in this work has helped The Geysers remain a global leader in geothermal energy production and environmental responsibility."
To commemorate the milestone, Calpine donated US$65,000 to the Clear Lake Environmental Research Centre (CLERC), a community-based non-profit focused on protecting and restoring the Clear Lake watershed and surrounding ecosystems.
Working across Lake and Sonoma Counties, CLERC coordinates wildfire prevention and habitat restoration efforts.It also brings together science, education and collaboration with local partners and tribes to build a more resilient and sustainable future for Northern California.
California State Senate President pro Tempore Mike McGuire called The Geysers a genuine feat of engineering and dedication.
“And Calpine's commitment to expanding renewable energy while protecting our natural resources is proof that innovation and sustainability are perfect partners in the world's fourth-largest economy.”
He added: “65 years is an incredible milestone for geothermal energy here in Lake and Sonoma counties, and we all look forward to what's ahead as the iconic Geysers continue to help shape California's transition to clean energy for the next generation.”
