Nessel briefs appeal over DTE Saline data center contracts

Michigan Attorney General Dana Nessel has filed a brief supporting her appeal of the Michigan Public Service Commission’s conditional approval of two special contracts for a 1.4 gigawatt hyperscale AI data center in Washtenaw County.

• The brief asks the Michigan Court of Appeals to invalidate the MPSC’s approval of contracts between DTE and Green Chile Ventures, LLC and to remand the matter for a contested case hearing.
• Nessel says the contracts were approved ex parte, involved redacted terms, and may shift costs to residential and other customers; the appeal had originally been announced on 2026-04-17.
