The Daily Dig
Prometheus Hyperscale is pushing forward on a new data center campus in Kaufman County, Texas, west of Dallas between Talty and Post Oak Bend City. The 500-acre site is planned to support up to 200MW of utility load across four large, liquid-cooled buildings. Company leadership has been clear that Texas is just the starting point for growth well outside its Wyoming roots.
The campus will run on behind-the-meter generation using Jenbacher J620 gas engines tied into Engie North America's adjacent battery energy storage system. Prometheus, previously known as Wyoming Hyperscale Whitebox, relaunched in September 2024 and scrapped its earlier 120MW concept in favor of a 1GW multi-state development strategy. Grey Rock Investment Partners is backing the platform, and Conduit Power is handling natural gas and battery backed deployments across Texas and Wyoming. The first facility is targeted for 2026, with additional sites lined up for 2027 and beyond.

TheJobWalk Thoughts
Behind-the-meter power from day one reshuffles the entire procurement sequence on a job like this. Generation packages, fuel infrastructure, and controls integration move to the front of the line before utility interconnect questions are even resolved. That means MEP and electrical scopes tied to the power plant side will likely be awarded before core and shell work gets going. Four buildings also point to a phased release strategy rather than one big bid cycle. Contractors and suppliers who wait for permits before positioning themselves will be late. The real early work here is generation and storage coordination, and that clock is already ticking.
