Connecticut experienced the steepest decline in residential electric bills of any state over the last year, a development that could reshape energy politics in the run-up to the 2026 election cycle and relieve pressure on households facing higher costs elsewhere in the country.
Numbers show a significant swing
Data from the U.S. Energy Information Administration show Connecticut’s residential electric bills dropped about 10% between June 2025 and June 2026. That contrasts with a roughly 5% average rise in residential rates across the United States during the same period.
As a result of that shift, Connecticut moved from having the fifth-highest residential rates among states and the District of Columbia to ranking 12th, now behind neighboring New York, Massachusetts and Rhode Island.
| Measure | Connecticut | U.S. average |
|---|---|---|
| Change in residential electric bills (June 2025–June 2026) | -10% | +5% |
| State ranking (residential rates) | 12th | N/A |
Why bills fell: the public benefits charge and fixed contracts
State officials and analysts point to changes in Connecticut’s public benefits charge as the main driver of the decline. That portion of electric bills funds state-mandated energy programs and agreements to buy power from carbon-free generators, including the Millstone Nuclear Power Station in Waterford.
Many of those purchases are covered by fixed-rate contracts that act as a hedge against fluctuating fossil-fuel prices. Because natural gas — which fuels a majority of New England’s power generation — became more expensive relative to those fixed-price, carbon-free contracts, the public benefits charge shifted from increasing bills to producing a net credit for customers.
"Everybody says, 'Ah, I hate the public benefits charge.' That's because coming out of COVID, the price of natural gas was virtually zero," Gov. Ned Lamont said in a recent interview. "We've more than made up for that in these ensuing couple of years, that's for sure."
Gov. Lamont negotiated the current Millstone contract in 2019. At the time, that and similar agreements were criticized after contributing to a sudden spike in rates during a summer heat wave two years ago. Today, the same arrangements are offering financial relief as gas-driven generation becomes costlier.
Broader context and local implications
The national picture has diverged from Connecticut’s experience. Across the country, rising gas prices and increased demand — including growth tied to data center construction — have helped push electricity costs higher. Connecticut’s relative improvement does not mean electric bills are low; rather, the state’s fall is notable because it bucked a national upward trend.
The timing has political significance. With Gov. Lamont seeking a third term, the change weakens a familiar criticism used by political opponents: that Connecticut’s climate and energy policies leave residents burdened with the nation’s highest power bills. The newly lower rank and the movement of the public benefits charge into credit territory could alter campaign messaging and voter perceptions on energy policy.
What this means for consumers
For residents, an immediate effect could be modestly lower monthly bills where the public benefits charge generates a credit. However, consumers should watch for changes in wholesale natural gas prices, future regulatory adjustments to the public benefits charge and the terms of long-term contracts that affect costs.
- Millstone Nuclear Power Station’s fixed pricing helped shield customers from higher gas-driven power costs.
- The public benefits charge — which funds clean energy and program costs — shifted to a credit as the market changed.
- Connecticut’s rank among states by residential rates moved from fifth to 12th.
State officials, regulators and utilities will continue monitoring market conditions and administering the programs financed through the public benefits charge. For now, Connecticut residents are seeing what state energy officials characterize as a rare reversal: lower local electric costs even as many Americans face increases.
