Eversource Connecticut commercial electricity prices, 2015 to 2025

In 2015 Eversource Connecticut billed its commercial customers on bundled service an average of 17.17¢ per kWh. In 2025 the figure was 22.92¢, so it rose 33% over 10 years. The average for all commercial customers in Connecticut rose 44% over the same period. The highest year was 2023, at 27.42¢. Between 2024 and 2025 it rose 0.8%.

Average use and average bill are the utility’s commercial sales and revenue divided by its commercial customers and by twelve. The bill is an all-in figure: energy, delivery, demand and fixed charges together. A few very large customers pull both averages up, so most businesses use and pay less than the average.

Eversource Connecticut customers who buy their energy from a supplier

In 2025, 77% of the commercial kWh Eversource Connecticut delivered went to customers buying their energy from a competitive supplier, and 34% of its commercial customers did so. The share by kWh is the larger because the businesses that shop tend to be the larger ones. Eversource Connecticut bills those customers for delivery only, at an average of 12.52¢ per kWh, which is the part of a bill that no supplier can change.

Residential, commercial and industrial prices at Eversource Connecticut

In 2025 the average commercial price at Eversource Connecticut was 21% below the residential figure and 47% above the industrial one. Larger customers take power at a higher voltage and use it more steadily, so at most utilities the average falls from residential to commercial to industrial. Which class an account falls in is the utility’s decision, and the line between commercial and industrial is drawn differently from one utility to the next.

The customers who buy their energy from a supplier are counted separately, and Eversource Connecticut bills them for delivery alone:

How Eversource Connecticut’s commercial rates are set

Eversource Connecticut is investor-owned, so its rates are set in cases before the Public Utilities Regulatory Authority and published in a tariff, which is a public document. A commercial account is billed on a rate schedule, chosen by the size of the account and the voltage it takes power at, and a schedule usually combines a fixed monthly charge, a charge per kWh and, above a certain size, a demand charge on the highest rate of draw in the month. The schedule code is printed on the bill. What a business in Connecticut can and cannot choose is on the Connecticut page.

Meters, time-varying rates and net metering at Eversource Connecticut

EIA counts 116,595 commercial meters at Eversource Connecticut in 2025 and reports no advanced (AMI) meters among them. Of those, 116,593 are automated-reading (AMR) meters, which send a reading to the utility for billing only, and 2 are standard meters. Without an advanced meter a business generally has no interval data, so its peak demand is read from the meter’s own register.

At Eversource Connecticut, 2,445 commercial customers were on a time-varying rate in 2025, about 2.2% of its commercial customers. A time-varying rate charges more in some hours than in others, so when a business uses power matters as well as how much. The kinds Eversource Connecticut reports offering commercial customers are time-of-use pricing.

EIA records 3,268 commercial net-metered generating systems at Eversource Connecticut in 2025, with 400 MW of capacity between them: about 29 for every 1,000 commercial customers. Net metering credits a customer for power its own system sends to the grid; the terms are in the utility’s tariff.

How reliable is Eversource Connecticut’s electric service?

Eversource Connecticut customers went without power for an average of 85 minutes in 2025, excluding major storms, with about 0.69 interruptions per customer. The average across U.S. utilities reporting the same way is 124 minutes. With major storms counted the figure was 217 minutes. These are averages over every customer of every class, so they describe the system and not any one street.

Where Eversource Connecticut serves

EIA records Eversource Connecticut serving customers in 8 Connecticut counties: Fairfield, Hartford, Litchfield, Middlesex, New Haven, New London, Tolland, Windham. A county can be shared between utilities, so this does not tell you who serves a given address. The utility that serves an address is the one named on its bill.

EIA lists ISO New England as its balancing authority. ISO New England is one of the organised wholesale markets, which run the grid and the wholesale power market across their area.

What these figures can and cannot tell you

• They are averages over every commercial customer. A utility whose commercial customers are mostly large averages fewer cents per kWh than one serving mostly small shops, so a lower figure can mean larger customers and not a lower rate.
• They are not a rate schedule. None of these figures is a charge printed in Eversource Connecticut’s tariff, and nothing here works out a bill from one. The tariff index lists the utilities whose filed schedules are quoted on this site.
• They are annual and final. EIA publishes utility figures once a year. The Connecticut page carries the state’s trailing 12 months, which is more recent and still preliminary.
• Bundled and delivery-only are different customers. The two prices describe different parts of the bill and are never added together or averaged.

For one building, the cost estimator gives a range by building type, size and state, and price by utility sets every utility side by side. Commercial vs residential vs industrial compares the classes in every state.
