Why is my Eversource Connecticut electric bill so high?
EIA respondent: Connecticut Light & Power Co. Reviewed October 14, 2026. Also searched as Eversource.
Eversource Connecticut did not have one residential price in 2025. EIA keeps the service types separate. 995,130 full service customers averaged 28.88¢ per kWh and $195.35 a month; 198,451 delivery only customers averaged 18.65¢ per kWh and $160.95 a month. A blended average would describe neither bill. The legal name in the filing is Connecticut Light & Power Co.
Connecticut's 2025 statewide residential average was 29.31¢. July 2026 was 24.16¢, versus 27.60¢ in July 2025 (−12.5%). Compare each Eversource Connecticut service type with those figures on its own.
From 2024 to 2025, the average monthly bill for full service changed +4.4%. Average use changed +3.1% and average price changed +1.3%. Holding the 2024 price fixed, the usage change accounts for $5.76 a month. The price change, applied to 2025 usage, accounts for $2.48.

The rate on the record
Investor-owned base rates are usually set in a state docket. Riders can change outside a full rate case. Average revenue per kilowatt-hour is total residential revenue divided by residential sales. It is not a tariff schedule.

Why a Eversource Connecticut bill moved
Usage, not the rate, was the larger piece
From 2024 to 2025 the average full service bill at Eversource Connecticut moved +4.4%, from $187.10 to $195.35. Holding the 2024 price fixed, the usage change of +3.1% is worth $5.76 a month. The price change of +1.3%, from 28.51¢ to 28.88¢, is worth $2.48 on 2025 usage.
Near the Connecticut average
28.88¢ per kWh is about even with Connecticut's 2025 residential average of 29.31¢. July 2026 in the state was 24.16¢, versus 27.60¢ a year earlier (−12.5%). The utility figure is a full year of average revenue. The state figure is one later month. A household that uses more than 677 kWh will not land on $195.35.
Two residential prices, on purpose
Eversource Connecticut reported more than one residential service with a real customer count: 995,130 full service customers at 28.88¢; 198,451 delivery only customers at 18.65¢. Bundled customers buy supply and delivery together. Delivery customers buy supply from someone else. A single blended rate would describe neither bill.
Season
Eversource Connecticut customers average 677 kWh a month in the 2025 filing. Connecticut households statewide averaged 704 kWh. Electric heat, a heat pump, or a cold snap sits well above a 12-month average, which is why a January bill and a May bill are not a rate case.
Time-of-use is already on the EIA schedule
EIA's 2025 dynamic-pricing file shows residential time-of-use activity at Eversource Connecticut, with 611 residential customers enrolled in dynamic pricing. The expensive window is in the tariff, not in that enrollment count. Shifting a dishwasher or an EV charger only helps if you are actually on that schedule.

How to lower the bill
- Read the kilowatt-hours against this filing's average of 677 kWh a month. If your use is the thing that moved, the dollar total can rise on an unchanged rate.
- Add the supply line and the delivery line before you decide the bill is high. This page keeps those EIA rows apart so they are not blended.
- In Connecticut, electric resistance heat dominates a winter bill. A heat-pump rate, where one is actually on the tariff, prices that usage differently from ordinary residential service. Confirm you are enrolled before you count on it.
- Start with LIHEAP for Connecticut (https://www.acf.hhs.gov/ocs/map/liheap-map-state-and-territory-contact-listing). A Eversource Connecticut discount beyond that program needs verification.
- 611 residential customers were already on a dynamic price in the 2025 EIA file. If you are one of them, the window on the tariff is the lever. If you are not, calling the utility to discuss the schedule is the first step, not shifting load you are not being charged extra for.
- If the read is marked estimated, the next actual read can true the account up or down. The tariff rule for that true-up needs verification.

Why is my Eversource Connecticut electric bill so high?
Eversource Connecticut did not have one residential price in 2025. EIA keeps the service types separate. 995,130 full service customers averaged 28.88¢ per kWh and $195.35 a month; 198,451 delivery only customers averaged 18.65¢ per kWh and $160.95 a month. A blended average would describe neither bill. The legal name in the filing is Connecticut Light & Power Co. Connecticut's 2025 statewide residential average was 29.31¢. July 2026 was 24.16¢, versus 27.60¢ in July 2025 (−12.5%). Compare each Eversource Connecticut service type with those figures on its own. From 2024 to 2025, the average monthly bill for full service changed +4.4%. Average use changed +3.1% and average price changed +1.3%. Holding the 2024 price fixed, the usage change accounts for $5.76 a month. The price change, applied to 2025 usage, accounts for $2.48.
What was Eversource Connecticut's average residential rate?
Using 2025 EIA-861 revenue and sales, the full service average was 28.88¢ per kWh. Average use was 677 kWh a month and the average bill was $195.35. This folds in whatever customer charges and riders the utility reported. It is not the marginal rate on your tariff.
Did Eversource Connecticut raise rates?
The full service average price changed +1.3% from 2024 to 2025, from 28.51¢ to 28.88¢. That is average revenue per kilowatt-hour, not a commission order. No 2025–2026 order for this utility was retrieved for this page. A separate rider can still move a single month.
What bill assistance can Eversource Connecticut customers ask about?
LIHEAP is the federal program for home energy bills (https://www.acf.hhs.gov/ocs/programs/liheap). Eversource Connecticut may also offer an income-qualified discount, budget billing, or a medical baseline. The current offer, income cutoff, and how to apply need verification on the utility site and with the state LIHEAP office and Connecticut Public Utilities Regulatory Authority.
Are data centers why this bill went up?
Large computing load is raising U.S. electricity demand, and regulators can later recover new generation and wires costs from customers. EIA has not published a dollar line that isolates data centers on this utility's residential bill. That pass-through needs verification.
