What the filing saysKentucky PSC Order, Case 2026-00115 (read in full): a Retail Electric Service Agreement (RESA) governs wholesale service from Big Rivers Electric to Kenergy Corp. for retail delivery to TeraWulf's Justified DataPower campus at the former Century Aluminum Hawesville site, Hancock County. Market-based pass-through: TeraWulf bears all MISO Day-Ahead/Real-Time energy, capacity, transmission, congestion, uplift and regulatory costs; negotiated wholesale/distribution demand adders increase annually and adjust further if Maximum Contract Demand is reduced after the take-or-pay period. 15-year initial term from the Construction Completion Date, with automatic 5-year renewals. Minimum 482 MW take-or-pay obligation for the first six years. Credit support equal to 2x TeraWulf's estimated highest monthly bill; TeraWulf must also prepay or fully collateralize its annual capacity obligation. Big Rivers/Kenergy may curtail for system integrity, local voltage, MISO directives, or a MISO EEA Level 3 event. The PSC found adequate customer protections and approved the RESA Aug. 21, 2026.
