Raeden Data Center (Gibraltar, former McLouth Steel site)

Raeden (filed as Cal Realty LLC). Filed, 100 MW

Raeden and Cal Realty, a Ferragon Corp company, want to convert an existing building at 27800 West Jefferson Avenue in Gibraltar, on the old McLouth Steel industrial site, into a 100 megawatt AI data center. Gibraltar's City Council passed a one year moratorium on data centers in March 2026 after the company filed its site plan application, and in August 2026 the developers sued the city in federal court, arguing the moratorium unfairly blocks a review they are entitled to under existing rules. The lawsuit is pending.

What it would mean nearby

The cooling design has not been reported. If it uses evaporative cooling, a 100 MW facility would draw roughly 317,000 to 1.1 million gallons of water a day, about what 3,600 households use.

DTE Electric is asking the commission for a 9.7% residential increase (2027 electric rate case (docket U-22046)). On a $160 monthly bill that is about $13 to $18 a month. 2026 electric distribution rate case (docket U-21860) raised residential rates 4.1% from March 2026: about $6 to $8 a month on a $160 bill. The order is meant to keep this one data center's power costs off the bills of regular DTE residential customers, but critics argue the fast, largely ex parte approval process did not fully test that promise.
