City of Peru
Average price is revenue divided by sales for the sector and year; it is not a tariff rate. Reliability figures are as reported by utilities to EIA on Form 861 and may use different calculation methods. Annual figures: Form EIA-861 for 2024, final release. Monthly state figures run to July 2026.
City of Peru serves 4,993 residential customers in Illinois as a municipal utility, according to its 2024 Form EIA-861 filing, with a service territory that touches 1 county.
Its average residential price that year was 12.00¢ per kilowatthour, 24% below the Illinois average of 15.87¢ and 27% below the US average of 16.48¢. The figure is residential revenue divided by residential sales, so it folds in fixed charges, riders and every rate schedule the utility bills under.
That works out to an average residential bill of $74.95 a month on average use of 625 kWh a month. Across Illinois the average bill was $109.99 on 693 kWh, so a bill gap reflects how much power households use as well as what each kilowatthour costs.
EIA's reliability file has no SAIDI or SAIFI entry for it in 2024; smaller respondents and energy-only suppliers are not asked for one.
The average price is up 7.9% on 2019, against up 21.8% for Illinois as a whole, and little changed on 2023. EIA's early release for 2025, which has not been fully edited, shows 12.48¢.

Bundled residential service only in the price, bill and use columns. Bill = residential revenue ÷ customers ÷ 12; use = residential sales ÷ customers ÷ 12. EIA describes its early release as not fully edited; it is shown for this utility alone and enters no average, median or rank on this site.
Sales by sector, 2024
| Sector | Customers | Sales | Share of sales | Revenue | ¢ per kWh, bundled |
|---|---|---|---|---|---|
| Residential | 4,993 | 37.4 GWh | 16% | $4,491,000 | 12.00¢ |
| Commercial | 1,159 | 81.6 GWh | 35% | $10,364,000 | 12.70¢ |
| Industrial | 9 | 117 GWh | 50% | $11,246,000 | 9.61¢ |
Customers, sales and revenue count every service type the utility reported (bundled, energy-only and delivery-only). The price column uses bundled service alone, because part-bill revenue would understate it. Sources of energy: 247.8 GWh in total, of which 12.6% was its own net generation and 216.7 GWh was bought wholesale; summer peak demand 49 MW.
Reliability
EIA's reliability file has no entry for City of Peru in 2024. Energy-only suppliers do not own the wires, and the smallest distribution utilities are not asked for SAIDI and SAIFI.
Generation at plants it operates, 2025
- Hydro 99.1% 34.4 GWh
- Petroleum 0.9% 320 MWh
Net generation of 34.8 GWh at power plants this utility operates, from Form EIA-923. It is not the mix delivered to customers: utilities also buy power wholesale (216.7 GWh in 2024), sell generation to others and may co-own plants that another company operates.
Counties in its service territory
Counties the utility listed on Form EIA-861 for 2024. Listing a county does not mean the utility serves all of it.
