​AG Mayes filed an appeal in Maricopa County Superior Court challenging the Arizona Corporation Commission’s approval of a special energy agreement between Tucson Electric Power (TEP) and and Beale Infrastructure for the Project Blue data center.

"The Arizona Corporation Commission cannot give away the constitutional authority Arizonans entrusted to it. The Commission does not have the power to let a utility and a data center operator quietly agree to set their own rates, cut the public out of the process, and call it a day. If we allow that here, we are telling every large energy customer in Arizona that they can negotiate sweetheart rates outside of public oversight — and ordinary Arizonans will be left to pick up the tab." – AG Mayes
