Fervo’s first 33 MW geothermal unit begins supplying Utah’s grid

The first GeoBlock begins delivering power

The Register reported that the first of three 33 MW GeoBlocks at Fervo Energy’s Cape Station power plant began supplying electricity to the grid. GeoBlocks are units in an enhanced geothermal system, which uses heat from Earth’s crust to heat water into steam for turbine generation. The report says the plant may eventually exceed four gigawatts of capacity; Fervo is currently working toward 900 MW of contracted capacity.

In 2023, Fervo demonstrated its enhanced geothermal system technology at Project Red, a site capable of generating 3.5 MW.

The first 33 MW GeoBlock at Cape Station has reportedly begun supplying electricity to Utah’s grid. Fervo expects commercial operation next week and says a further 66 MW could come online by New Year.

Separating 33 MW online from future plans

The reported grid connection turns one 33 MW unit of an enhanced geothermal project into operating generation. The same report describes planned additions rather than capacity already online, including another 66 MW by New Year and 0.5 GW by 2028.
