Assembly Committee Approves Papan Legislation to Create Strategic Plan for In-State Geothermal Energy

SACRAMENTO — The California State Assembly’s Committee on Natural Resources has approved Assembly Bill 526, authored by Assemblymember Diane Papan (D-San Mateo), which would establish a statewide strategic plan to dramatically expand geothermal energy production in California. This vital step forward ensures geothermal energy—a clean, continuous, and reliable resource—can play a central role in meeting the state’s ambitious climate goals.

“Geothermal energy is the key to California’s long-term energy stability and in reaching our environmental goals,” said Assemblymember Papan. “Unlike wind and solar, geothermal provides clean, continuous power, ensuring that we have a reliable energy source as we transition to a carbon-free future.”

California has committed to achieving 100% carbon-free retail electricity by 2045 and reaching net-zero emissions statewide, but the state’s current reliance on solar and wind energy has limitations due to intermittency caused by weather and time-of-day constraints. Geothermal energy, by contrast, provides firm, around-the-clock power and is uniquely positioned to support the state’s long-term energy needs.

Despite being the largest generator of geothermal power in the United States, California currently sources only 5% of its in-state electricity generation from geothermal energy—well below what is needed to meet the state’s climate mandates. Developing geothermal facilities takes time, often more than a decade, which makes early planning and coordination essential.

“We cannot reach our climate targets if we treat geothermal as an afterthought,” said Assemblymember Papan. “AB 526 ensures that we recognize the full potential of geothermal energy and start investing in it with the seriousness it deserves. This is about securing California’s energy future—and doing it with clean, homegrown power.”

Assembly Bill 526 will require that the California Energy Commission develop a comprehensive strategic plan for in-state geothermal development. This will include identifying ideal locations for new geothermal projects; assessing environmental and economic impacts; and facilitating public engagement and transparency among several objectives. 

Assembly Bill 526 will now move to the Assembly Appropriations Committee in the coming weeks.
