Project Blue is a data center campus planned for up to 10 buildings and 2 million square feet, with 600 megawatts of capacity at full build-out, on a 290-acre parcel north of the Pima County Fairgrounds in unincorporated Pima County. Tucson's City Council voted 7-0 in August 2025 to reject annexation and any city water service, but developer Beale Infrastructure kept the project alive by buying the land from Pima County, switching to a closed-loop air-cooled design, and drilling groundwater wells that Arizona water regulators approved in May 2026, which could draw up to 31 million gallons a year. Construction began in April 2026 despite ongoing protests over water use, and Pima County is now drafting a data center moratorium and ordinance partly in response.

Power bills in Pima County
Most of the county is served by Tucson Electric Power.
Tucson Electric Power is asking the commission for a 11.6% residential increase (2026 general rate case (docket E-01933A-25-0103)). On a $160 monthly bill that is about $16 to $21 a month. This is a service contract, not a residential rate change. The protections in it exist to keep the cost of serving the data center from shifting onto Tucson homes; whether they hold is the thing to watch in TEP's future rate cases.
TEP is asking for about 11.6 percent more on residential bills, roughly 12.92 dollars a month at median usage. The attorney general's office argued in testimony that only about a 4 percent increase is justified. TEP says this case is unrelated to the Project Blue data center agreement; a decision could come before the end of 2026.
