New Haven, CT commercial electricity rates
Who delivers electricity to New Haven businesses, how retail supplier choice works there, the Connecticut commercial average with its EIA data month, and who regulates it. Market context with its source and date, never a quote.
EIA averages, data through 06/2026, published per state. All-in means supply and delivery together; supplier contract quotes cover the supply portion only, so the two are not directly comparable.
New Haven commercial electricity at a glance
New Haven (New Haven County) is delivered by United Illuminating, which stays the wires company whichever supplier a business picks. New Haven is United Illuminating's home city; UI delivers to 17 towns around New Haven and Bridgeport. The EIA publishes a statewide figure, not a city one: the average Connecticut commercial account paid 19.62¢ per kWh all-in, supply and delivery together, versus 14.19¢ nationally (EIA, 06/2026), and used about 6,167 kWh a month (EIA, through 2026). That average mixes corner stores with hospitals, so it is market context rather than a quote for any one business, and supplier contract quotes cover the supply portion only, so the two figures are not directly comparable.
