Eversource says it wants to raise rates about 11% starting next July. It is the company's first rate increase in almost a decade.

Eversource says for a residential customer using about 700 kilowatt-hours per month, the increase would be about $25. If you use more electricity, the increase could approach $40 a month.

Eversource says it has been showing an operating revenue loss of approximately $503 million annually, excluding storm costs, from 2018 to 2023.

In a statement, Eversource said: "Increased investment is needed to maintain the level of affordable reliability and resiliency that customers have come to expect."

State Attorney General William Tong sent News 12 Connecticut a statement saying in part: "Connecticut families are getting crushed by unaffordable energy costs while Eversource executives crow to Wall Street over surging profits and rake in multimillion-dollar bonuses."

Consumer Counsel Claire Coleman, whose office advocates for utility ratepayers, said the filing would trigger one of the state's most significant utility reviews in years.

State Democrats and Republicans say high utility bills were among the issues they fought this past legislative session, and this proposal continues to make Connecticut unaffordable.
