ACC Approves a Surcharge Reduction and Refund for TEP Customers

Phoenix, Ariz. —   The Arizona Corporation Commission voted unanimously (5-0) to approve Tucson Electric Power Company’s proposal to reduce its Purchased Power and Fuel Adjustment Clause (PPFAC) surcharges.  In addition, the Commission also voted unanimously to approve TEP’s proposal to refund residential customers approximately $9.5 million in excess uncommitted Demand Side Management Surcharge (DSMS) funds.

In February, TEP filed a request to adjust its PPFAC which will result in a decrease in average residential bills of approximately $11.91 per month assuming average monthly usage of 767kWh.  Several commissioners voiced their enthusiasm in voting for this reduction.

Additionally, the Commission has directed TEP to apply unspent DSMS funds as credits to residential customers.  TEP will apply credits over a two-month period, resulting in refunds of $5.63 to appear on customers’ June and July 2024 bills.

All documents relating to this agenda item can be found in the Corporation Commission's online docket at and entering docket number E-01933A-22-0107.
