Fervo Energy has gained massive ground for the geothermal industry, with the Texan startup company signing two 15-year Power Purchase Agreements (PPAs) for 320 MW of geothermal power with Southern California Edison. This will give California some much-needed renewable baseload, but more importantly, it will help fund Fervo Energy’s expansion of next-generation geothermal energy.
