Overview
- Dana Nessel asked the Michigan Court of Appeals to void the Michigan Public Service Commission’s conditional approval and require a contested case review.
- The commission had approved two DTE contracts to power a planned 1.4‑gigawatt Saline Township data center with a minimum 19‑year term and later denied Nessel’s request to reopen the case.
- A contested case would allow legal discovery, public testimony, and outside intervention to test whether rates stay flat and to examine redacted terms such as exit and collateral fees.
- The commission says the approvals carry some of the strongest consumer safeguards and forecasts about $300 million in customer affordability benefits, which it plans to defend in court.
- DTE says the developer, Oracle, must pay for three battery storage facilities and any grid upgrades to protect other customers’ reliability, a point central to the case’s outcome and its precedent for future data center deals.
