Adams Fork Harless Data Center Energy Campus

Project details

Capacity 2457 MW reported. Status planned. City . County Mingo. State WV. Grid .

Overview

West Virginia Watch reported a 3 December 2025 federal lawsuit by ten Mingo County residents against TransGas Development Systems and federal agencies over the Adams Fork Energy Project: an ammonia plant plus two methane-and-diesel power plants meant to run as microgrids for two data centers, one at Twisted Gun Golf Course in Wharncliffe and one at Harless Industrial Park near the Mingo–Logan line in Holden. The plants would each house 117 engines, 114 of them full-time, with diesel in 40 tanks per site if gas is unavailable. The West Virginia Highlands Conservancy said WVDEP’s Division of Air Quality issued permits R13-3714 and R13-3715 on 2 October 2025 after August and September hearings, authorizing the two off-grid gas plants; at full capacity each could generate more than 2,400 MW. TransGas has touted 5,000 temporary construction jobs and 300 permanent roles. The mapped pin is the Harless Industrial Park data-center energy campus, not the Wharncliffe golf-course plant. Residents asked the Southern District of West Virginia to halt ground-disturbing work until Fish and Wildlife consultation, a Clean Water Act permit, NEPA review, and any required FERC pipeline approvals. The Conservancy said project documents contemplated drawing water from underground mine pools under the golf course, and that HB 2014 limits local regulation of noise, lighting, and land-use impacts. Monarch Compute Campus is Mason County’s Nscale AI park. Fundamental Ridgeline Data Center is Tucker County’s Fundamental Data campus. This Mingo County page is the TransGas Harless Adams Fork data-center energy pin.
