Utilities in Connecticut reported an average of 1 hour and 27 minutes without power per customer in 2025, with 0.69 interruptions per customer, when major storm days are left out. That outage time is shorter than the median state (127 minutes).

Customers in Connecticut had 122,249 net-metered residential solar systems with a combined 1,333.3 megawatts of capacity in 2025. That works out to 77.3 systems for every 1,000 households, which ranks 5 of 51 places. Net metering lets a home with solar offset what it uses from the grid, so it changes the bill math for those households. Our net metering guide explains how the credit works.

Outage figures are reported by utilities and follow different standards, so compare states with care. The median state averaged 127 minutes of outage per customer in 2025.

• Check your rate before your habits. Usage here is close to or below the national figure, so the plan and the price per kWh on your bill often matter more than conservation. Our bill reading guide shows where to look.
• Compare supplier offers. Because Connecticut allows retail choice, the supply price on your bill can be higher or lower than the default. Compare at least three fixed-rate offers and check the contract length and the cancellation fee.
• Ask about time-of-use pricing. 2 of the 6 largest providers report residential time-of-use programs in EIA data. If you can shift laundry, charging and cooling to cheaper hours, the savings can be real. Our time-of-use guide explains how to test it.
• Ask about budget billing. Many utilities spread costs across the year. Read how budget billing works before you sign up.
• Price your appliances. The electricity cost calculator shows what a space heater, dryer or pool pump costs to run at your rate.
