Your power bill

Data centers change bills through the utility's own rate cases and large load tariffs, not a separate charge you would see by name. Pending electric rate cases in Arizona, in dollars a month, is our sister site's full tracker for this state.

2026 general rate case Tucson Electric Power
Pending 11.6% requested

TEP's general rate case evidentiary hearing was held April 22 through May 12, 2026, with closing arguments due in July 2026. TEP requested new rates take effect September 1, 2026, but no confirmed final Commission decision date has been found in current reporting.

2025 general rate case Arizona Public Service
Pending 16.4% requested

APS's general rate case evidentiary hearing ran from May 18 through July 7, 2026, one of the longest in Arizona Corporation Commission history, with about 36 intervenors, more than 50 witnesses and over 300 exhibits. An administrative law judge is expected to issue a recommended opinion and order by late November 2026, after which the full Commission must vote by December 31, 2026; key contested issues include a proposed Extra High Load Factor rate for large industrial and data center customers and a Formula Rate Adjustment Mechanism.

Project Blue data center energy service agreement Tucson Electric Power
Approved

The Arizona Corporation Commission approved TEP's contract to serve the 286 MW Project Blue data center near Tucson on a 4 to 1 vote in December 2025, over two hours of public opposition centered on water use. TEP says the data center pays the standard largest-customer rate with minimum bills and termination fees so the buildout cost stays off residential bills.
