US Startup To Supply 320 MW Geothermal Energy To Power 350,000 Homes In California

An anonymous reader quotes a report from Interesting Engineering: Fervo Energy has announced the signing of two power purchase agreements (PPAs) totaling 320 MW with Southern California Edison (SCE), one of the nation's largest electric utilities. The two PPAs, signed for 15 years, will provide clean, and affordable power for the equivalent of 350,000 homes across Southern California. The geothermal energy from Fervo will help California transition to a cleaner and more reliable power source. According to Fervo Energy, SCE will purchase the power from its 400 MW Cape Station project currently under construction in southwest Utah. The first 70 MW phase of Fervo Energy's project is expected to be operational by 2026 and the second phase will be operational by 2028, according to a release by the company. Geothermal energy, being a carbon-free and weather-agnostic source, will also prove to be a reliable source for meeting California's power consumption demands. Unlike wind and solar power plants, geothermal energy can be sourced around the clock and on demand to cater to increased energy needs. Earlier in July 2023, Fervo Energy had claimed to achieve "commercial scale" geothermal energy production from its Project Red demonstration site in northern Nevada. [...] For the demo, Fervo had used a horizontal well pair that extended to 3,250 feet (990 m) and reached a temperature of 375 degrees Fahrenheit (191 degrees Celsius). During the test period, Fervo achieved a flow rate of 63 liters per second, sufficient to generate 3.5 MW of electricity. One megawatt of energy can power approximately 750 homes at a time. Data collected during this pilot was used to improve the design for Fervo's next well pair and double the energy output generated.Read more of this story at Slashdot.
