What rising SRP rates could cost you
SRP rates have risen about 1.7% per year. Enter your bill to see what that pace of increase could compound to over time, and what you have likely already absorbed. This is an estimate, not a guarantee.
Estimate only. Projects your current bill forward at SRP's historical average rate increase (1.7% per year, from EIA data); it assumes your usage stays the same except for any add-ons you select. Actual rates depend on your usage, rate plan, and the utility's future filings, and are not guaranteed. This is general information, not financial advice.
Current residential rates
SRP residential rates are shown below, from the utility's published tariffs and the public Utility Rate Database. Rates vary by plan, season, and usage and change over time.
| Plan | Energy charge | Fixed / basic |
|---|---|---|
| E-23 Basic Price Plan (flat, no TOU or demand) - effective Nov 2025 | Winter 11.03 c/kWh; Summer (May, Jun, Sep, Oct) 12.10 c/kWh; Summer Peak (Jul, Aug) 14.04 c/kWh | Monthly service charge $20 (Tier 1 multifamily), $30 (Tier 2 typical single-family), or $40 (Tier 3, >225 amp service) |
| E-23 Basic Price Plan - prior schedule (effective May 2019, incl. Nov 2023 fuel adjustment) | Winter 9.76 c/kWh; Summer 12.67 c/kWh (0-2,000 kWh) / 13.10 c/kWh (2,001+ kWh); Summer Peak 13.33 c/kWh (0-2,000 kWh) / 14.46 c/kWh (2,001+ kWh) | Monthly service charge $20.00 (flat, all customers) |
| E-13 Time-of-Use Export Price Plan (solar; TOU energy, no demand charge) - effective Nov 2025 | On-peak: Summer 20.89 c/kWh, Summer Peak 23.44 c/kWh, Winter 14.31 c/kWh. Off-peak: Summer 11.24 c/kWh, Summer Peak 11.25 c/kWh, Winter 10.47 c/kWh. Solar exports credited at 3.45 c/kWh | Monthly service charge $20 / $30 / $40 by tier (same tiers as E-23) |
Rates are from SRP's official FY26 ratebooks (E-23 Basic and E-13 Time-of-Use Export), effective with the November 2025 billing cycle, plus the prior E-23 schedule (effective May 2019, with the November 2023 fuel and purchased power adjustment) for comparison. SRP totals include base distribution/transmission/generation plus the Fuel and Purchased Power Adjustment. Summer = May, Jun, Sep, Oct billing cycles; Summer Peak = Jul, Aug; Winter = Nov-Apr. SRP sets its own prices through a public pricing process (no Arizona Corporation Commission rate case), so these are board-approved tariffs, not ACC-ordered rates.
Net metering and solar export: No retail net metering - flat 3.45 c/kWh export credit (net billing)
SRP does not offer traditional retail net metering. Because SRP is a self-governed public power district outside Arizona Corporation Commission jurisdiction, it sets its own solar rules. Rooftop solar that you use in your home offsets electricity at the full retail rate, but any surplus you export to the grid is bought back at a low flat export credit, currently 3.45 cents/kWh, regardless of time of day, on the new Time-of-Use Export plan (effective Nov 2025) - well below the roughly 11 to 14 cents/kWh you pay to buy power back. New solar customers go onto TOU export plans (E-13 / E-28): the newest E-13 TOU Export plan has no demand charge but prices grid energy on time-of-use periods (much higher on-peak), so the value of solar depends heavily on self-consumption and battery storage rather than export credits. SRP's older legacy solar plans (E-15 Average Demand and E-27 Customer Generation), which add monthly demand charges of about $9.16 per kW of on-peak demand on top of a net-billing credit, are closing to new enrollment and sunset for all solar customers by November 2029. Bottom line: this is a net-billing / low export-credit (and historically demand-charge) structure, not 1-for-1 retail net metering, so solar economics favor self-consumption and storage.
What it means for solar
SRP rates have risen about 1.7 percent per year over the past decade. Solar can offset that grid cost, every kWh you generate and use is a kWh you do not buy, but how much you save depends on your rate level and on how exported power is credited (No retail net metering - flat 3.45 c/kWh export credit (net billing)). Where exports are worth little, using your own solar, often with a battery, matters more than selling surplus back. Whether solar makes sense depends on your usage, roof, and rate plan, so get a site-specific quote.

FAQ
How much have SRP electricity rates gone up?
SRP's average residential price rose about 16 percent since 2015, roughly 1.7 percent per year, reaching about 13.46 cents per kWh in 2024.
Does SRP offer net metering for solar?
SRP uses No retail net metering - flat 3.45 c/kWh export credit (net billing). See the net metering section above for exactly how exported solar is credited and what that means for your system.
Is solar worth it with SRP?
It depends on your electricity usage, roof, system size, and whether you add a battery. Higher rates and rate increases make solar more attractive, but the value of exported power depends on SRP's net metering rules. Get a site-specific quote rather than relying on a general estimate.
Where does this rate data come from?
The per-year prices come from the U.S. Energy Information Administration's Form 861, and the current rate structures come from the public Utility Rate Database. Both are public, free, and updated regularly.
