The Nexus Hubbard Power Generation Facility is the natural-gas plant proposed for the Nexus Data Center Hubbard campus in Hill County, Texas. Nexus Hubbard Power, LLC applied to the Texas Commission on Environmental Quality for air permits, and the agency issued a preliminary decision with a draft permit in September 2026. The applicant states it will not be physically interconnected with a utility distribution system and that onsite power is consumed onsite. Reported capacity ranges from 612.93 MW in the original engine registration to 1,600 MW in press reports and up to 7,200 MW at full build-out.

Profile

Generation: The original registration covered 612.93 MW of baseload natural-gas engines. The consolidated application keeps 24 of the original 30 engines and adds simple-cycle and combined-cycle turbines. Press reports put the plant at 1,600 MW, and an environmental-organization alert describes up to 7,200 MW.

Role for the data center: The state review calls the generating units the main power sources for the data center, with diesel engines only for emergency use. The applicant describes no physical interconnection with a utility distribution system.
