How much does SRP charge per kWh in 2026?

SRP’s estimated effective residential rate is about 11.83 cents per kWh as of June 2026. A typical home using 1,000 kWh a month pays roughly $148, including the about $30 monthly customer charge. Commercial service runs about 11.50c/kWh. This is a representative average; your exact rate depends on the tariff, season, and fuel and rider charges on SRP’s official rate schedule.

2026 published rate: SRP's standard residential plan is the E-23 Basic Price Plan, a seasonal all-in rate rather than a time-of-use plan. Effective with the November 2025 billing cycle, the standing per-kWh price, which already folds in generation, fuel, delivery, transmission, and rider charges, is about 10.97 cents in winter (the November through April billing cycles), 12.04 cents in summer (May, June, September, and October), and 13.98 cents in summer peak (July and August). SRP is temporarily lowering the per-kWh price by 0.38 cents for the May through October 2026 billing cycles because of lower fuel and market power costs, with prices returning to the standing levels for the November 2026 cycle. On top of the per-kWh charge is a fixed monthly service charge of $30.00 for a typical single-family home (Tier 2), $20.00 for an apartment or condo (Tier 1), or $40.00 for a home wired above 225 amps (Tier 3). Blended across the year the standing energy charge works out to about 11.83 cents per kWh, so a typical 1,000 kWh home pays roughly $148 a month all-in, about 14.8 cents per kWh once the fixed charge is counted, below Arizona's statewide residential average. Because SRP is a public power utility, its prices are set by an elected board rather than the Arizona Corporation Commission, and its residential customers cannot shop for a competitive supplier.

SRP on Form EIA-861: 2024 Reported Sales, Customers and Realised Prices

EIA's 2024 Form 861 census lists 1 operating company behind SRP (Salt River Project, utility 16572), together serving 1,053,407 residential accounts (bundled plus delivery-only) in AZ across 3 counties. Weighted across those companies, the 2024 average realised residential price for bundled service was 13.46 cents per kWh (total residential revenue divided by total residential sales). These are annual averages of what customers actually paid, including fuel and rider charges, so they will not match the tariff rate on a current bill; the estimated effective rate above is the site's forward-looking figure.

Data year 2024, EIA-861 final released 3 December 2025. Res. accounts = residential accounts served, bundled plus delivery-only where the company has delivery-only rows; the residential, commercial and industrial prices are the bundled figures (the price basis). Rank is by residential accounts served among the state's utilities with bundled or delivery service; share is the company's share of the state's residential sales in MWh, not of its customers. Delivery-only rows show the wires charge only. The 2025 early-release column is preliminary and unvalidated by EIA.

Frequently Asked Questions

What is the SRP rate per kWh in 2026?+
SRP's standard residential plan is the E-23 Basic Price Plan, a seasonal all-in rate rather than a time-of-use plan. Effective with the November 2025 billing cycle, the standing per-kWh price, which already folds in generation, fuel, delivery, transmission, and rider charges, is about 10.97 cents in winter (the November through April billing cycles), 12.04 cents in summer (May, June, September, and October), and 13.98 cents in summer peak (July and August). SRP is temporarily lowering the per-kWh price by 0.38 cents for the May through October 2026 billing cycles because of lower fuel and market power costs, with prices returning to the standing levels for the November 2026 cycle. On top of the per-kWh charge is a fixed monthly service charge of $30.00 for a typical single-family home (Tier 2), $20.00 for an apartment or condo (Tier 1), or $40.00 for a home wired above 225 amps (Tier 3).

What is the current SRP rate per kWh?+
SRP (Salt River Project)'s estimated effective residential rate is about 11.83 cents per kWh as of June 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 11.50c/kWh, and the monthly fixed customer charge is roughly $30 regardless of usage.
What rate structure does SRP use?+
SRP (Salt River Project) uses a seasonal rate structure. Seasonal rates vary between summer and winter billing periods, reflecting demand patterns in the service area.
How do I calculate my SRP bill from the rate per kWh?+
Multiply your monthly kilowatt-hours by the per-kWh rate, then add the fixed customer charge. Using SRP's estimated effective residential rate of 11.83 cents per kWh and its roughly $30 monthly fixed charge, a home using 750 kWh a month works out to about (750 x $0.1183) + $30 = $118.73 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 SRP 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 SRP made?+
SRP is a public power utility whose prices are set by its publicly elected Board of Directors, not the Arizona Corporation Commission. On 27 February 2025 the Board approved an overall 2.4 percent increase in electric prices, effective with the November 2025 billing cycle; SRP put the change at about $5.61 more a month, roughly 3.4 percent, for a typical residential customer using 1,117 kWh. A decrease to the Transmission Cost Adjustment followed with the January 2026 billing cycle. Consult the price plan linked above for current pricing.
