Switch Grand Rapids (The Pyramid Campus)
Switch. , 320 MW
Switch's Pyramid campus near Grand Rapids has been operating for years inside a converted Steelcase pyramid building and is one of the largest data center campuses in the eastern United States. The company is expanding the site toward a planned 1.8 million square feet and up to 320 megawatts of power, with a second building nearly complete and a third in planning. This is an established, already operating site rather than a new proposal.

What it would mean nearby
The cooling design has not been reported. If it uses evaporative cooling, a 320 MW facility would draw roughly 1.0 million to 3.7 million gallons of water a day, about what 11,700 households use.
Consumers Energy is asking the commission for a 9.8% residential increase (2027-2028 electric rate case (docket U-22070)). On a $155 monthly bill that is about $13 to $17 a month. 2026 electric rate case (docket U-21870) raised residential rates 8.9% from May 2026: about $12 to $16 a month on a $155 bill. This does not change a typical home bill by itself, but it sets the rules meant to stop the cost of new data center power hookups from being spread across every Consumers Energy customer's rate.
