Connecticut commercial electricity rates
The average all-in rate and monthly usage for the average Connecticut commercial account, how retail supplier choice works there, who delivers the power and who regulates it. Market context with its source and date, never a quote.
EIA averages, data through 06/2026. All-in means supply and delivery together; supplier contract quotes cover the supply portion only, so the two are not directly comparable.
Connecticut commercial electricity at a glance
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. Among the 14 states with retail electricity choice, Connecticut has the 8th lowest all-in commercial average. The regulator is the Connecticut Public Utilities Regulatory Authority. Voltcheckr LLC is registered as an electricity broker in Texas (PUCT Broker Registration BR260102) and is not currently registered in Connecticut.
How retail electricity choice works in Connecticut
Connecticut businesses served by Eversource or United Illuminating keep their utility for delivery and can buy the supply portion from a competitive electric supplier approved by PURA, or stay on the utility's standard service rate. PURA approves electric aggregators as a separate class, and by Connecticut law an aggregator represents customers and may not take compensation from a supplier. Municipal utilities such as Wallingford and Norwich serve their customers outside the program.
