New Electric Rate Increase Effective January 2023

Following a months-long study, public discussions on the cost of delivering electric service to Belmont home, businesses, and municipal buildings, and a vote of approval by the Municipal Light Board, Belmont Light announced increases to it electric rate design that went into effect with the January 2023 billing cycle.

The new rate design allows Belmont Light to keep up with skyrocketing prices in the energy markets, sparked by a dramatic increase in natural gas costs, among a number of other factors while continuing to upgrade its electric delivery system and improve upon its reliability.

For the average Belmont Light residential customer using 500 kilowatt-hours per month, the new rate design will amount to an approximately $14.61 increase on their electric bill.  Please read on for more details on the new rate design, what it means for you, and how we compare to neighboring towns on current and future electricity rates.

Here is an example of how each utility’s increase would affect a customer using an average amount (500 kWh) of electricity per month:
