Best Electricity Rates in Connecticut (July 2026)

Your baseline in Connecticut is the utility "Standard Service" supply rate, which the state resets every January 1 and July 1. From July 1, 2026 it is 11.57c/kWh with Eversource and 11.99c/kWh with United Illuminating, both down from the higher winter 2026 rates. That supply rate is only part of your bill - the delivery charge stays with your utility and is not competitive. To pay less than Standard Service you compare fixed-rate offers from state-licensed retail suppliers on Connecticut's official EnergizeCT Rate Board and check the supply rate against the Standard Service numbers below on an apples-to-apples basis.

Bills since May 1, 2026 also carry a temporary PURA public-benefits credit - about $30 a month for a typical Eversource household and about $34 for UI - running through at least September 2026, so what you actually pay runs below the all-in average shown above. When you compare a competitive supplier, watch for teaser rates that jump after a few months, variable-rate plans with no cap, and cancellation fees that can wipe out the savings.

Connecticut Electricity Rate: What You Need to Know

Connecticut electricity averages 27.37 cents per kWh for residential customers as of May 2026, according to the EIA Electric Power Monthly. This is 8.93c above the US average of 18.44c/kWh. The average monthly bill for Connecticut households is $204 based on typical usage of 695 kWh.

Connecticut has among the highest electricity rates in the mainland US - 27.37c/kWh (May 2026), about 1.5 times the national 18.44c and in line with its high-cost New England neighbors. Two regulated utilities deliver power: Eversource Connecticut (the former Connecticut Light and Power) serves most of the state, while United Illuminating (UI) serves the Bridgeport and New Haven area. Connecticut allows retail choice - households can buy generation supply from a competitive provider through the state's Energy Choice / Standard Service comparison tools - but most stay on their utility's default Standard Service rate, which is reset twice a year through competitive procurement. A large slice of a Connecticut bill is the "public benefits charge", a line item that funds state-mandated programs such as low-income assistance, energy efficiency, and legacy power-purchase contracts including the Millstone nuclear deal. That charge spiked to roughly 4 cents per kWh in 2024 and drew heavy public criticism. In an interim decision effective May 1, 2026, the Connecticut Public Utilities Regulatory Authority (PURA) turned the public benefits charge into a temporary credit, cutting the typical Eversource residential bill by about $30 per month (4.3c/kWh) and the typical UI bill by about $34 per month (4.9c/kWh) through at least September 2026 - which is the main reason Connecticut's EIA residential average fell to the 27.37c shown here (May 2026) from about 32.2c in April 2026, the last full month before the credit took effect. The structural drivers of Connecticut's high baseline remain: elevated ISO-New England capacity prices, natural-gas pipeline constraints into New England, and limited in-state generation.

Generation mix: Natural gas 65%, nuclear 15%, renewables 20%. The fuel mix is a primary driver of electricity rates - states with abundant hydro or nuclear tend to have lower rates, while states dependent on imported petroleum (Hawaii) or natural gas pay more.

Year-over-year change: Connecticut rates fell 13.4% year-over-year as of May 2026. This compares to the US average increase of 6.2% over the same period.
