DTE ties possible rate hike freeze to data center approvals, Nessel says it’s ‘ransom note’

April 29, 2026

DTE Energy has filed a request for a $474. 3 million electric rate increase that would raise residential rates by 9. 7%, claiming the funds are needed to improve grid reliability and transition to cleaner energy sources.

Who is affected

  • DTE Energy residential customers (facing 9.7% rate increase)
  • DTE Energy shareholders (seeking 10.25% return on equity)
  • Oracle and OpenAI (data center operators with contracts under review)
  • Google (planning Michigan data center operations)
  • Related Digital (developer of Saline Township data center)
  • Michigan Attorney General Dana Nessel (appealing data center approvals)
  • Michigan Public Service Commission (regulatory body reviewing requests)
  • Citizens Utility Board of Michigan and other ratepayer advocacy groups
  • Union of Concerned Scientists
  • Michigan League of Conservation Voters
  • Over 2,500 union construction workers and 450+ on-site workers (projected jobs from Saline project)

What action is being taken

  • DTE Energy is filing a $474.3 million electric rate hike request
  • Attorney General Dana Nessel is intervening in DTE's latest electric rate case
  • Nessel is appealing the conditional approval of data center power contracts in Michigan Court of Appeals
  • The Michigan Public Service Commission is vigorously defending the conditional approvals
  • EGLE is reviewing a National Pollutant Discharge Elimination System application for the Saline Township site
  • Major construction is underway at the Saline Township data center site
  • EGLE is reviewing a joint wetland permit for the Van Buren Township project

Why it matters

  • This case has significant implications for utility regulation, customer costs, and energy infrastructure development in Michigan. DTE customers already pay the highest energy costs in the Midwest while experiencing poor reliability, making additional rate increases particularly contentious. The approval process raises fundamental questions about utility accountability and whether large corporate customers like data centers will genuinely reduce costs for residential ratepayers or instead require expensive infrastructure upgrades that regular customers subsidize. The outcome will set precedents for how Michigan regulates utility rate increases tied to major commercial developments and whether fast-tracked approval processes adequately protect consumer interests. Additionally, the case affects Michigan's energy transition strategy, as DTE plans to use data center revenue to justify investments in new baseload generation, potentially including natural gas with carbon capture.

What's next

  • The Michigan Public Service Commission will review DTE's $474.3 million rate hike request
  • The Michigan Court of Appeals will hear Attorney General Nessel's appeal of the data center contract approvals
  • EGLE will complete its review of the National Pollutant Discharge Elimination System application for the Saline Township site
  • EGLE will review the joint wetland permit for the Van Buren Township project
  • The MPSC will rule on additional approvals needed for elements like energy storage for the Saline Township data center
  • DTE will pursue a contested rate case for the Van Buren Township data center
  • Construction will continue on the Saline Township data center project
