Origis brings another 500 MW online at its West Texas solar complex

Rockhound in Ector County reaches nearly a gigawatt operating, with another gigawatt of solar and storage planned by 2029.

Origis Energy has brought another 500 megawatts of solar online at its Rockhound complex in West Texas, taking the site's operating capacity to nearly a gigawatt. The three newly finished phases sit in Ector County and join Swift Air Solar, a set of three adjoining Origis projects totaling about 500 MW inside the same complex. Origis says Rockhound is now among the largest renewable energy complexes in the country.

The next stage is another gigawatt of solar plus battery storage by 2029, which would push the whole site past 2 GW. Storage is the part that changes the project's character: it lets midday generation be held and released when the grid actually wants it, turning a solar farm from a daytime commodity into something closer to firm supply.

Rockhound already sells under long-term contracts to Meta, Occidental, dsm-firmenich and Bekaert, and Origis is pitching the next phase to data centers for co-location and corporate power agreements. That is the current shape of cheap power in America — West Texas has the land, the sun and the existing energy infrastructure, and the buyers with the most urgent demand are compute operators. Capacity built to win those contracts still lands on the same grid everyone else draws from.

What to watch is whether the storage half gets built on schedule and who signs for it. Origis said the complex supports the Texas grid and brings local economic development, but published no job or investment figures with the announcement.
