Eversource Files for an Estimated 11% Rate Hike in Connecticut: What It Means for Homeowners
Connecticut families just got the news. The latest Eversource rate hike — an estimated 11% increase — has been filed with state regulators and could take effect July 1, 2027. According to NBC Connecticut, the average residential customer could see an estimated $25 to $40 added to their monthly bill, depending on how the request is structured.
Governor Ned Lamont, Attorney General William Tong, and Consumer Counsel Claire Coleman have all publicly responded. And homeowners across the state are asking the same question: how much higher can this go before we do something about it?
The Numbers Behind the Estimated Hike
Here is what Eversource filed with Connecticut regulators on May 20, 2026, as reported by NBC Connecticut and WTNH:
- Estimated 11% rate increase across all customer classes, approximately 13% for residential customers
- Estimated $25 per month higher bills for a typical residential customer (about 700 kWh) if regulators approve “securitization,” or up to an estimated $40 per month without it
- Approximately $503 million in annual operating revenue is what Eversource is seeking, excluding storm costs from 2018 through 2023
- Effective July 1, 2027 if approved by Connecticut’s Public Utilities Regulatory Authority (PURA)
- First electric rate review Eversource has filed in Connecticut since 2017
Consumer Counsel Claire Coleman, whose office represents Connecticut ratepayers in regulatory proceedings, called the filing “one of the most consequential utility review proceedings in years,” per NBC Connecticut.
What the Governor Is Saying
In a message to Connecticut families released May 21, 2026, Governor Lamont made his position clear.
“The company asking you to pay more just posted $1.69 billion in profit last year.”
Governor Ned Lamont, May 21, 2026
The Governor’s statement laid out a series of figures that, according to his office, describe Eversource’s recent financial performance and executive compensation:
- $1.69 billion in profit reported last year, per the Governor’s office
- 23% increase in shareholder returns over the prior year, per the Governor’s office
- $13.5 million in CEO compensation, described as a 19% raise, per the Governor’s office
- $16 million CEO severance if terminated, and $60 million if the company is sold, per the Governor’s office
- CEO compensation reported at 94 times the average Eversource employee salary, per the Governor’s office
“Shareholders carry almost no risk. Connecticut ratepayers carry it all.”

Attorney General William Tong, also reacting to the filing, was equally direct, per NBC Connecticut:
“Connecticut families are getting crushed by unaffordable energy costs while Eversource executives crow to Wall Street over surging profits.”

What the Eversource Rate Hike Could Cost a Connecticut Household
Using the $25 to $40 monthly estimate reported by NBC Connecticut, here is what the increase could mean over time if approved as filed:
- An estimated $300 to $480 more per year, every year the rate remains in effect
- An estimated $3,000 to $4,800 over the next decade from this single rate case, assuming the new rate holds at that level
These are estimates based on the figures reported in the news coverage above. The final impact depends on PURA’s decision, how securitization is handled, and a household’s actual usage.
Why More Connecticut Homeowners Are Looking at Solar
