Wyoming data center firm Prometheus Hyperscale is targeting a new development in Texas.

“Excited to bring to market our newest Prometheus Hyperscale site near Dallas!” Trevor Neilson, president of Prometheus Hyperscale, said on LinkedIn this week. “While we are very proud of our Wyoming roots, this entry into the Lone Star State alongside Engie North America and Conduit is incredibly exciting and is just the beginning!”

The 500-acre site is set to be located west of Dallas between Talty and Post Oak Bend City in Kaufman County.

Neilson’s post suggests the liquid-cooled site could reach 200MW of utility load and feature four large buildings.

The company is set to use behind-the-meter power through Jenbacher's J620 gas engines and will be connected to Engie’s adjacent battery energy storage system.

Launched around 2020 and formally known as Wyoming Hyperscale Whitebox, Prometheus was relaunched in September 2024. The Wyoming-based company initially planned to develop a 120MW campus back in 2020. However, after its relaunch, plans were revised to 1GW with plans to target multiple sites, including Arizona and Colorado.

In September 2025, Prometheus partnered with Engie to colocate data centers with renewable assets in Dallas, Texas, though full details weren’t shared.

Backed by private equity firm Grey Rock Investment Partners, Conduit Power provides on-site natural gas and battery storage assets. Conduit first announced a partnership with Prometheus in September 2025 to deploy power solutions in Texas.

In November, the firm announced purchase orders for 75 Ecomax 33 power generation units, powered by Jenbacher 620 engines, with AB Energy.

Totaling some 250MW of capacity, the units were part of 300MW of total behind-the-meter natural gas generating capacity being deployed at data center sites in Texas and Wyoming, colocated with battery storage. The company said the first facility is expected to come online in 2026, with additional locations planned for 2027 and beyond.
