Helios is a former bitcoin-mining site off County Road 112 in Dickens County that Galaxy Digital is converting into an AI data center campus, with CoreWeave as the tenant under a 15-year lease. ERCOT has approved more than 1.6 GW of capacity for the campus. Coverage cites a longer-term ceiling of 3.5 GW, which Galaxy's own January 2026 release does not state.
