MANCHESTER — The average Eversource residential customer would see the energy portion of their monthly electric bill increase $3.44 starting Feb. 1 if state regulators approve the request, a spokesman said Friday.

But that same user would be paying $7.56 a month less for energy than a year ago, according to Eversource spokesman William Hinkle.

Energy costs typically are more expensive during the winter months.

The energy portion makes up more than 50 percent of the total bill. The remaining portion, including the delivery charge, hasn’t been finalized for the Feb. 1 change, according to Hinkle.

The typical residential user consumes about 600 kilowatt hours a month, he said.

The rate-hike request will go before the state Public Utilities Commission next week.

When Eversource announced last year it was selling its power generation plants, the utility said customers who buy energy through Eversource should expect to see lower energy prices due Eversource’s buying power in the wholesale electric market.

Hinkle said that would be the case under the proposed rates set to start this February.
