Phoenix, Ariz. — At the Arizona Corporation Commission’s Open Meeting on March 12, 2025, Vice Chairman Nick Myers joined the Commission in a 5-0 vote approving Tucson Electric Power Company’s (TEP) application to adjust its Purchased Power and Fuel Adjustment Clause (PPFAC) rate by increasing its credit back to customers.

The new PPFAC rate results in a decrease in average residential bills of approximately $4.38 per month assuming average monthly usage of 767 kWh. The new PPFAC rate provides a credit to customers of ($0.007150) per kWh through March 31, 2026. The prior PPFAC rate effective in June 2024 was a credit of ($0.001446) resulting in a decrease in average residential bills of approximately $11.91 per month assuming average monthly usage of 767 kWh (Decision No. 79363).

“I am so pleased that for a second year in a row the Commission has been able to approve a credit back to customers through TEP’s PPFAC for a total reduction of over $16 per month,” commented Vice Chair Myers, “the PPFAC continues to work as it should with its true-up component and taking into account lower forecasted cost of procuring fuel and power.”

The new PPFAC rate will become effective April 1, 2025.
