PowerCompute Increases Contracted Power at Mississippi Site to 11 Megawatts Under TVA's New Data Center Tariff
PowerCompute (PWCM) increased contracted power at its Mississippi site from 8.5 MW to 11 MW under TVA's new data center tariff. The company avoided $1.5M/MW capacity charges by securing the contract before October 1, 2026. Columbus Light and Water returned a $300K deposit, which PowerCompute will use for capacity buildout. The site operates 2,373 Antminer machines with a 205 PH/s hashrate.
How this was made
The 30-second read
Why it matters
The contract avoids a $1.5 M per MW capacity charge, improves cash flow, and enables further mining expansion through the returned $300k deposit.
Market read
Operational cost reduction and capacity increase are material for PWCM's valuation and may influence other miners facing TVA tariffs.
What to watch
Potential regulatory risk if the classification of mining as data‑center load is challenged.
Background
PowerCompute operates 26 MW of owned electricity for Bitcoin mining and HPC, with the Mississippi site now at 11 MW after a new contract with Columbus Light & Water.
Ticker impact
PowerCompute announced a new power contract increasing its Mississippi site capacity to 11 MW with no TVA capacity charge and a $300k deposit return.
likely upside as the company avoids a $1.5 M per MW capacity charge and can expand mining output.
Cost avoidance and added capacity are material to a micro‑cap miner; investors typically reward such operational improvements.
Market effects
Shows how TVA's new data‑center tariff creates cost differentials for miners; could pressure peers without similar contracts.
May boost investor sentiment toward US‑based crypto miners operating in the Southeast.
Limited to the niche Bitcoin mining sector; no broad market effect.
Counterpoint
If TVA later enforces the capacity charge on retroactive contracts, the cost advantage could evaporate.
