United Illuminating Co
United Illuminating Co is investor owned serving 256,302 residential customers in Connecticut, at an average residential price of 34.04¢ per kilowatt-hour.
That price is derived, and it is annual. It is total residential revenue divided by total residential sales in EIA’s 2024 survey — not a tariff, and not this month’s rate. For what a kilowatt-hour costs in Connecticut right now, see the state page, currently 24.32¢.
What it reported, by service
| Service | Residential customers | Residential | Commercial |
|---|---|---|---|
| Bundled | 256,302 | 34.04¢ | 24.27¢ |
| Delivery | 55,989 | 19.59¢ | 11.61¢ |
A utility can file bundled service and delivery-only service separately. A delivery-only price excludes the energy itself, so the two are not comparable and are not ranked against each other.
How often the power goes out
| Minutes without power per customer, 2024 | 121.8 minutes (SAIDI, including major event days) |
|---|---|
| Interruptions per customer | 0.79 (SAIFI) |
| Excluding major event days | 49.2 minutes the figure utilities are benchmarked on |
| Reported under | IEEE standard |
The headline figure includes major event days, because a customer who lost power for three days in a storm lost power for three days. See how this compares nationally.
