UI, Eversource’s New Rates Will Surprise You: Here’s What You’ll Pay Soon In CT

CONNECTICUT — Both of Connecticut's major electric utilities have now filed a lower standard service rate for the summer period.

United Illuminating Monday announced that, following a regulatory filing with the Connecticut Public Utilities Regulatory Authority, standard service supply rates for the second half of 2025 — July 1 through Dec. 31 — are expected to drop by 13.1 percent, with residential customers specifically expected to see a slightly higher 13.9 percent decrease in supply rates.

Here's how much you'll save as a UI customer

Accordingly, UI officials said, the average residential customer using 700 kilowatt-hours of electricity can expect to see an electric bill reduction of approximately $13.19 per month.

The calculations were filed with PURA, which oversees the procurement of electricity on behalf of customers using the company's Standard Service rate. Those customers make up about 82 percent of UI's customer base. Per Connecticut law, UI does not own power plants or generate electricity; instead, UI procures power on behalf of Standard Service customers and passes the cost on one-for-one at no mark-up or profit to the company.

On May 16, Eversource filed a new Standard Service rate for residential customers that would change from the current 11.19 cents per kilowatt-hour to 9.75 cents per kWh, according to the filing.

For the typical residential customer using 700 kWh per month, that represents a decrease of approximately $10, or 5 percent, on a total bill, according to the Eversource filing.

In Connecticut, the energy supply price changes twice a year – on Jan 1 and July 1.

UI officials statement on the new summer rates

"Electric distribution companies like UI do not control or profit from supply rates, but with energy costs top of mind for so many of our customers and other stakeholders, we are pleased that customers will soon see some measure of savings in their supply rates, which make up nearly half of the typical UI bill,” UI President and CEO Frank Reynolds said in comments accompanying the filing Monday. "We remind customers that while supply rates are going down, usage often increases during the hot summer months, primarily due to the use of air conditioning, which can diminish the savings they feel. Thus, as summer approaches, we encourage customers to be mindful of tips and tricks to manage their usage – such as turning up the thermostat when it’s not needed and weatherizing their home or business – to take full advantage of the supply rate decreases they will see beginning in the July billing cycle."

Pending regulatory approval, from July 1 to December 31, 2025, UI anticipates that supply rates for residential customers using its standard service rate will drop from 13.57 cents per kWh to 11.68 cents per kWh, a 13.9 percent drop in supply rates that accordingly drives a 5.24 percent drop in residential customers’ overall monthly bills. For the average residential customer using 700 kWh of electricity per month, it equates to the aforementioned savings of approximately $13.19 per month.

Impact of Public Benefits Charges on customers bills

Officials from both utilities said in their filings that customers continue to be impacted by high Public Benefits Charges, which pay for the costs of energy-related policy programs passed by legislators and implemented by PURA. Those programs include subsidies and incentives for renewable energy projects, energy efficiency programs, and other sustainability programs as well as assistance programs that reduce energy bills for residents who can provide financial hardship. The Public Benefits Charge has been included on Connecticut energy bills since 1999.

"Even if you keep your thermostat set at the same temperature all summer long, you'll use more electricity when it's 95 degrees outside, as opposed to 80 degrees, because your system is working that much harder to keep your home or business cool," Eversource President of Connecticut Electric Operations Steve Sullivan said.
