Who owns Arizona's electric companies
| Type | Utilities | Homes in AZ | Share of homes |
|---|---|---|---|
| Investor-owned utility | 5 | 1,801,702 | 57.0% |
| Municipal utility | 1 | 15,507 | 0.5% |
| Electric cooperative | 7 | 189,667 | 6.0% |
| Public power district | 3 | 1,112,638 | 35.2% |
| State-owned utility | 2 | 27,297 | 0.9% |
| Federal power system | 1 | 12,018 | 0.4% |
Each type is run differently. An investor-owned company answers to shareholders and a state commission. A municipal utility answers to a city. A cooperative answers to its members. That is why the same state can have very different prices and service from one address to the next.
What Arizona utilities charge, by type
| Type | Utilities with a price | Average cents per kWh |
|---|---|---|
| Investor-owned utility | 5 | 16.59 |
| Municipal utility | 1 | 20.56 |
| Electric cooperative | 7 | 12.51 |

Source: U.S. Energy Information Administration, Form EIA-861 (final 2025 data). Customer-weighted average of the prices utilities report for bundled residential service. It leaves out delivery-only customers and retail providers.
Outside the investor-owned companies, the largest municipal utility is City of Mesa (15,507 homes), and the largest electric cooperative is Trico Electric Cooperative (53,721 homes), and the largest public power district is Salt River Project (SRP) (1,074,095 homes).
Price differences between types come from costs, customer density and the way each type is financed, so a lower average does not decide which is better for your home.
