MANCHESTER — Eversource NH is asking state regulators to approve a temporary rate increase to recover millions spent to modernize its electric system.
If approved, the temporary rate on July 1 would equal about 2 percent across all customer groups or $33 million.
This would add $3.50 more to the monthly bill of a typical residential customer using 600 kilowatt-hours per month, officials said.
In the Friday filing with the Public Utilities Commission, the company asks regulators to make the first update in a decade to rates that the utility charges that relate to its distribution system.
The filing was delayed until the company sold the last of its power plants last year, officials said.
Over the past decade, the company has made $1 billion in equipment changes that reduced the frequency and duration of power outages, company executives said.
“We’ve had a steadfast commitment to enhancing the reliability of the electric grid, making it more resilient to New England’s extreme weather,” said Bill Quinlan, president of Eversource New Hampshire.
“We’ve modernized our control centers and automated the system, enabling power to be redirected to our customers when interruptions occur. These investments are providing huge benefits to our customers and set the stage for a cleaner energy future in New Hampshire.”
Based on past practice, it’s likely to take state regulators nearly a year to complete its review, so permanent rates are not likely until the spring of 2020, officials said.
