How much does APS charge per kWh in 2026?

APS’s estimated effective residential rate is about 14.05 cents per kWh as of May 2026. A typical home using 1,000 kWh a month pays roughly $154, including the about $13 monthly customer charge. Commercial service runs about 12.15c/kWh. This is a representative average; your exact rate depends on the tariff, season, and fuel and rider charges on APS’s official rate schedule.

2026 published rate: APS's standard Fixed Energy Charge plan (Rate Schedule R-1) bills a tiered energy charge that depends on your average monthly usage: about 12.93 cents per kWh for homes averaging 600 kWh or less, 14.05 cents for 601 to 999 kWh, and 15.42 cents at 1,000 kWh or more, all effective 8 March 2024 under Arizona Corporation Commission Decision No. 79293. A basic service charge of roughly $13 a month plus monthly fuel and adjustor riders are added on top, so the all-in effective rate for a typical home sits close to Arizona's statewide residential average of 15.23 cents per kWh (EIA, May 2026). The big 2026 story is a pending increase: in June 2025 APS filed a rate case seeking a 13.99 percent net revenue increase, about $20 more a month for a 1,000 kWh household, with Corporation Commission hearings held in May 2026 and a decision expected late in 2026. Arizona Attorney General Kris Mayes has filed testimony arguing the increase should be cut to about 3 percent. APS also offers time-of-use and demand-charge plans that can beat the fixed plan for households that shift usage away from summer afternoons.

What is the current APS rate per kWh?+
APS (Arizona Public Service)'s estimated effective residential rate is about 14.05 cents per kWh as of May 2026. This is a representative average; your exact rate depends on the tariff, season, and fuel/rider charges shown on the utility's official rate schedule (linked below). The estimated commercial rate is 12.15c/kWh, and the monthly fixed customer charge is roughly $13 regardless of usage.
What rate structure does APS use?+
APS (Arizona Public Service) uses a tiered rate structure. Tiered rates charge a higher rate once your usage exceeds a baseline allowance (typically set at 50-100% of average usage for your climate zone).
How do I calculate my APS bill from the rate per kWh?+
Multiply your monthly kilowatt-hours by the per-kWh rate, then add the fixed customer charge. Using APS's estimated effective residential rate of 14.05 cents per kWh and its roughly $13 monthly fixed charge, a home using 750 kWh a month works out to about (750 x $0.1405) + $13 = $118.38 a month. The table above shows the same math across usage levels from 250 to 1,500 kWh. This is a representative estimate; your exact rate depends on the tariff, season, and fuel and rider charges on the official schedule linked above.
How do I find my APS rate on my bill?+
Your electricity bill shows the total kWh consumed and the charges applied. Look for the 'energy charge' or 'supply charge' line item - this is the per-kWh rate times your usage. Delivery charges (transmission and distribution) are listed separately and represent a significant portion of your total rate. The fixed customer charge appears as a flat line item. Your effective combined rate (all charges / total kWh) may differ from the tariff rate due to the fixed charge amortization.
What recent rate changes has APS made?+
APS's base rates were last reset in 2024 (Arizona Corporation Commission Decision No. 79293, effective 8 March 2024). In June 2025 the company filed a new rate case seeking a 13.99 percent net revenue increase - about $20 a month for a typical 1,000 kWh residential customer - with Corporation Commission hearings held in May 2026 and a decision expected later in 2026; any approved rates would take effect after that.
