Adams Fork Harless Data Center Energy Campus
TransGas Development Systems. Approved. 2400 MW.
New York based TransGas Development Systems proposed an off grid natural gas power plant to run more than 2,400 megawatts of generation, powering a data center at the Harless Industrial Park near the Mingo-Logan county line in Holden. The state Department of Environmental Protection held public hearings in September 2025 after community outcry over air quality, then granted air quality permits for the project in October 2025 despite the opposition. Mingo County residents later filed a federal lawsuit against the company over the power plant and data center plans.

What it would mean nearby
The cooling design has not been reported. If it uses evaporative cooling, a 2400 MW facility would draw roughly 7.6 million to 27.4 million gallons of water a day, about what 87,500 households use.
