Municipal Light Plant


Property owners with Electric, Water, or Sewer account balances of 60 days or more overdue as of November 30th will have those utility arrearages added as a lien to their quarterly property tax bill issued December 31st.

Utility payments received after November 30th will not affect the lien balance. Payments to be applied to balances in arrears after November 30th must be made to the Town Assessor.

One organization, one goal, one team. We're here to serve you. 

Concord Municipal Light Plant (CMLP) is a municipal-owned, public power utility offering electric and broadband Internet service under the direction of the Town Manager. With 110 miles of streets in the service territory, CMLP serves approximately 8,200 meters providing 170,000 Megawatt Hours (MWh) to 6898 residential, 1244 commercial, and 69 municipal customers.

Grid & Substations
CMLP maintains a grid that consists of a Town-owned distribution system with substations, power lines, light poles, and transformers. We operate two electric distribution substations. The substation at Forest Ridge is the primary substation which functions as a gateway for all electricity coming into Concord from Eversource.

Power Supply
CMLP does not generate electricity; we purchase power from third party suppliers, passing the costs to customers without a markup. How the Town sources electricity significantly impacts Concord’s ability to achieve its climate goals. 

CMLP is committed to providing 100% carbon-free electricity by 2030. CMLP has been de-carbonizing its power supply by purchasing renewable power from developers in Massachusetts, New Hampshire, Connecticut and Maine and purchasing Renewable Energy Certificates (RECs). In 2021 we expect 84% of CMLP’s sales will come from non-carbon emitting power sources.

CMLP offers a wide array of programs and services designed to encourage energy conservation, beneficial electrification, and generation of carbon-free solar power on homes and businesses. Residential and commercial energy assessments help customers identify worthwhile energy efficiency measures. 

Rebate programs help customers offset the cost of improvements such as weatherization, high efficiency lighting, rooftop solar PV arrays, heat pumps for space and water heating and purchases of electric vehicles and home EV charging systems. Off-peak EV charging incentives reduce the impact of charging on peak demand. Technical support services help customers navigate the switch from conventional heating systems and vehicles to heat pumps and electric cars.

CMLP has a dedicated group of 41 people who together strive to supply the Town with reliable and affordable electricity and broadband. The Team is made up of line crews, engineers, electricians, accountants, technicians, conservation specialists, technology professionals and a customer care team. We’re here to serve you.
