California community choice aggregator MCE has entered into new contracts for 134 megawatts of geothermal energy.

“Due to the 24/7 nature of geothermal energy, these contracts fill critical evening hours when power costs are high and emissions are the highest, helping reduce long-term costs for customers and reducing system emissions,” MCE noted.

The geothermal projects include:

• Mayacma Project in Lake County, California online in 2024; 7 megawatts and $21,000 in community benefits; New state-of-the-art geothermal facility.
• Humboldt House Project in Pershing County, Nevada online in 2025; 20 megawatts and $60,000 in community benefits; Completely new build
• The Geysers in Lake and Sonoma Counties, California incremental MW online in 2027; 100 megawatts from the existing Geysers facilities and the addition of 7 new megawatts; 107 megawatts and $100,00 in community benefits.

MCE is a not-for-profit public agency and the preferred electricity provider for more than 580,000 customer accounts and 1.5 million residents and businesses across Contra Costa, Marin, Napa, and Solano counties.
