Arizona Electricity Rates
Rate data for Arizona is being refreshed. The regulator and market facts below are current; figures return with the next data load.
Can you choose your electricity supplier in Arizona?
No. Arizona has not opened its residential electricity market to competition, so the utility that delivers your power also sells it. Its prices are set in rate cases before the Arizona Corporation Commission, and the rate you pay depends on which utility serves your address, your rate schedule, and the season.
Grid operator: No RTO; Western bilateral market (WECC). Wholesale power costs flow through to retail bills on the regulator's schedule rather than month to month, which is why regulated-state rates move more slowly than the market-based states listed below.

Metro Phoenix is split between two utilities, so the first step is an address check: ACC-regulated APS (three business days' notice, credit-scored deposit of about two average bills) and SRP, a landowner-governed political subdivision that is not on the ACC's regulated list (power on within an hour, a flat $290 standard deposit that SRP says is waived in many cases after an Experian check); both offer evening-peak time-of-use or demand plans, and a June 1 to October 15 no-shutoff rule applies at APS while SRP suspends shutoffs only in July-August and on Extreme Heat Warning days.
Who will deliver your power in Arizona
The utility is fixed by your address. These are the largest in the state, with what each says it needs from a new customer.
Arizona Public Service (APS)investor-owned
APS says it serves homes and businesses in 11 of Arizona's 15 counties and publishes downloadable service-area maps, including a separate one for the downtown Phoenix metropolitan area; its start-service page tells you to double-check that APS serves your address first. About approximately 1.4 million homes and businesses (per APS).
APS asks you to confirm the address is in its territory and to schedule service at least three business days in advance; only the person on the account (or an appointed agent) can change it. Most new customers pay a security deposit depending on a credit check, roughly two times the average bill, billed on the first APS bill and waivable with a passing credit check, an acceptable Letter of Credit from another electric company, or a joint account holder with good payment history; the deposit is returned with interest in the 13th month if there are no more than two late payments in 12 months.
Start service with Arizona Public Service →Salt River Project (SRP)public power district
Central Arizona in and around the Phoenix Valley; SRP's territory page has an address lookup because some addresses get SRP power, some water, and some both. About more than 1.2 million electric customers, more than 2 million people served (per SRP).
You must be at least 18 and provide an SRP-approved ID including a Social Security number (without an SSN you provide a driver's license or other government ID and pay a deposit); most meters have power within an hour of the request. SRP's standard residential deposit is $290, often waived after SRP validates your SSN with Experian and scores you (lift any Experian freeze first), held at least 18 months, earning interest paid as a January bill credit, and applied to your bill in the 19th month if you have an on-time history; the prepaid SRP M-Power plan instead takes a $100 refundable deposit plus a $30 service-establishment fee.

Tucson Electric Power (TEP)investor-owned
The Tucson metropolitan area. About more than 458,000 customers (per TEP).
TEP routes start, stop and transfer requests through its My Account portal, with Customer Care at 520-623-7711 weekdays 7 a.m. to 6 p.m. TEP may require a deposit of up to two times the estimated average monthly bill, credited back after 12 consecutive months with no more than two delinquencies, and waived if you had comparable TEP service in the past two years without delinquency, bring a credit-verification letter from your previous electric utility, or have a deposit guarantee from an acceptable agency.
Start service with Tucson Electric Power →UniSource Energy Services (UES / UNS Electric)investor-owned
Electric service in Mohave County (Kingman and Lake Havasu City) and Santa Cruz County (Nogales and most of the county); it also sells natural gas in five counties. About more than 107,000 electric customers (per UES).
UES, TEP's sister company, uses the same My Account start/stop/transfer flow, with Customer Care at 1-877-837-4968 weekdays 7 a.m. to 6 p.m. Its rate page says you pick your pricing plan at sign-up and are placed on the standard rate if you choose none.
Start service with UniSource Energy Services →Mohave Electric Cooperative (MEC)cooperative
Bullhead City, Mohave Valley, Golden Shores, Peach Springs, Hualapai Mountain, Grand Canyon Caverns and the Havasupai Indian Reservation, across portions of three Arizona counties. About 36,700 members and 43,500 meters (per MEC).
New members file an online Residential Membership Application with a copy of their ID and a letter of credit, pay a $5.00 membership fee, and call member service at (928) 763-1100 with questions. A letter of good credit from your previous electric provider is required to waive the deposit, or you can sign up for Mohave Prepay to avoid one; the rate book lists a $40.00 establishment-of-service fee.

Deposits, ID, and supplier choice in Arizona
Deposits. ACC rule R14-2-203 bars a regulated electric utility from charging a new residential applicant a deposit if they had comparable service with that utility in the past two years without more than two late payments, bring a credit-verification letter from their last electric utility, or provide a guarantee letter or surety bond; any deposit is capped at two times the customer's estimated average monthly bill, must earn interest, and must be refunded after 12 months without more than two delinquencies. SRP does not appear on the ACC's list of regulated electric utilities and sets its own $290 standard deposit under its own credit policy. (law.cornell.edu)
Choosing a supplier. None of the APS, SRP, TEP, UES or Mohave Electric start-service pages offers a supplier choice; you sign up with the utility that serves your address (APS, SRP, TEP, UES, a co-op, or a city, district or tribal provider). The ACC's retail-competition rule (R14-2-1602) makes a utility's customers eligible for competitive service only on a date set by Commission order. APS tells movers to double-check that it serves the address, and SRP's territory page has an address lookup.
The ACC regulates APS, TEP, UNS Electric and the cooperatives (including Mohave) but has no authority over city, irrigation-district or electric-district utilities or tribal utilities; SRP's power arm is an agricultural improvement district and political subdivision of the state governed by landowner-elected boards; it is absent from the ACC's regulated electric utilities list, and its deposit and shutoff-moratorium terms come from its own credit policy rather than the ACC rules that bind APS.

Programs that change what you pay
- Rooftop solar (net metering)limited
- For rooftop systems that requested interconnection since September 20, 2018, the ACC-approved Resource Comparison Proxy (RCP) export rate sets what APS and TEP pay for excess solar, and you keep the rate in place when you requested interconnection for up to 10 years; TEP's RCP is $0.0462 per kWh for October 1, 2026 through September 30, 2027 and cannot fall more than 10% a year, and APS mails a check for year-end credit balances of $25 or more. SRP, which is not on the ACC's regulated list, credits exports at a fixed $0.0187 per kWh on its export price plans or banks excess at the retail rate on its Customer Generation and Average Demand plans.

SRP (not ACC-regulated) suspends shutoffs in July and August and during National Weather Service Extreme Heat Warnings, and Mohave Electric uses NWS 'Major' or 'Extreme' temperature alerts instead.

Questions people ask before moving to Arizona
How far ahead should I set up electricity before moving to Arizona?
APS asks for at least three business days' notice, while SRP says most meters have power within an hour of a request made to its 24/7 line and TEP and UES schedule starts through My Account; Mohave Electric takes an online membership application and answers questions at (928) 763-1100. A week of notice covers all of them.

Can I choose my electricity supplier in Arizona?
Not on any of the utilities' start-service pages: under ACC rule R14-2-1602, a utility's customers become eligible for competitive service only on a date set by Commission order, and your address decides whether you are an APS, SRP, TEP, UES, cooperative, city, district or tribal customer. APS asks you to double-check that it serves your address (it publishes a separate downtown Phoenix metro map), and SRP's territory page has an address lookup.
Sources: law.cornell.edu, azcc.gov, aps.com, srpnet.com
Will I have to pay a deposit, and how much?
APS runs a credit check and, if it wants a deposit, charges roughly two times the average bill on your first invoice, refunding it with interest in the 13th month; SRP's standard deposit is $290 but is often waived after an Experian check, and TEP's cannot exceed two times the estimated average monthly bill. A credit-reference letter from your previous electric utility waives the deposit at ACC-regulated utilities under R14-2-203, and Mohave Electric requires that letter or its prepay plan to skip the deposit.
Sources: aps.com, srpnet.com, tep.com, law.cornell.edu, mohaveelectric.com
Can my power be shut off in the summer heat?
Not for nonpayment at APS, TEP or UNS Electric between June 1 and October 15, which those utilities chose under the ACC's R14-2-211 instead of a 95°F forecast trigger; SRP keeps power on in July and August and during Extreme Heat Warnings, and Mohave Electric holds off when the NWS issues Major or Extreme temperature alerts. Charges keep accruing in every case: the ACC rule has APS, TEP and UNS bill the past-due balance in installments afterward, SRP keeps bills due on its normal terms with late fees still charged, and Mohave offers payment plans.

Which rate plan should a new Arizona customer pick?
Both big Phoenix utilities offer time-of-day plans: APS's on-peak window is 4pm-7pm weekdays (with an optional demand charge on your highest on-peak hour), and SRP's are 6-9 p.m. or 5-10 p.m., with a 90-day trial if you want to switch; UES puts you on the standard rate if you do not choose, and TEP's plan comparison tool needs 12 months of history at your address. APS, SRP and UES all run flat-rate plans if you would rather not manage peak hours.

What help is there if I cannot afford the summer bills?
Arizona LIHEAP through DES pays $160 to $640 a year plus up to $500 in crisis aid for households under the income limits ($5,647 a month for four), and each utility layers its own discount: APS Energy Support cuts 25% or 60% off electricity charges, SRP's Income-Qualified Discount is $10 or $35 a month, and TEP Lifeline is $20 a month, all at or below 200% of the federal poverty level.
