The following is a press release from the City of Marlborough


MARLBOROUGH – The Colonial Power Group, the City’s aggregate broker, reported third quarter savings of over $78,000 for residents who take part in the City of Marlborough’s Community Choice Power Supply Program.

The City contracted with energy supplier Inspire Energy in August for a $0.09390 per kWh. for all rate classes and this rate will be in effect until January 2024. 

This program is a municipal aggregation that enables local government to combine the purchasing power on behalf of its residents and businesses to provide them with an alternative to National Grid Basic Service.

By leveraging its purchasing power, the City is able to negotiate a lower rate.

The City currently has 12,800 customers in its Community Choice Power Supply Program and anticipates a greater savings in the fourth quarter as National Grid’s winter rate of $0.12388 took effect on November 1, 2020.

National Grid’s basic rate changes twice a year, in May and November. 

“The City has an aggregation committee chaired by Council President Michael Ossing that reviews rates and trends and goes out to bid to get the best possible rate for our residents. Although it’s pennies on the dollar, it adds up to a significant savings for both residential and commercial customers,” said Mayor Arthur Vigeant. 

If you would like to take part in the program, please contact Colonial Power at 866-485-5858 x1 and to learn more about the program, visit
