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.

On billsafter the decision
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.
