Fervo's next-gen geothermal plant just went commercial

A geothermal company just did something nobody else in the world has pulled off. It sold real, round-the-clock power from a new kind of plant. Fervo Energy turned on a 33-megawatt unit at its Cape Station site in Utah in late September. It synced to the grid, then started commercial operations on September 30. Fervo calls it the world's first greenfield 'enhanced geothermal' project to reach that stage.

Geothermal power itself isn't new — Iceland and parts of California have run on it for decades. The catch has always been location: old-style geothermal only works where natural hot water sits close to the surface. Fervo's approach borrows a trick from oil and gas fracking. It drills deep into hot rock almost anywhere, cracks it open, then pumps water through to make steam. That means geothermal power could eventually go anywhere, not just a handful of lucky spots on the map. This first phase is small, just 33 megawatts, compared with the much larger buildout Fervo has planned for the site.

Can Fervo actually scale this up to its full planned size, or does drilling-anywhere geothermal stay a boutique technology? The company beat its own deadline on phase one, which is a good early sign. Power-hungry data centers and AI companies are already hunting for exactly this kind of steady, round-the-clock electricity. If Fervo keeps delivering, it won't lack customers.
