As described in the CMLP Strategic Plan, CMLP is purchasing Renewable Energy Certificates (RECs) to help green our power supply. Renewable Energy Credits (RECs) are tradable, non-tangible energy commodities that provide proof that 1 megawatt-hour (MWh) of electricity was generated from a renewable energy resource and was fed into the shared system of power lines which transport energy. Solar renewable energy certificates (SRECs) are RECs that are specifically generated by solar energy.

This YouTube video from the U.S. Environmental Protection Agency RECs: Making Green Power Possible explains why RECs make power green.

There are changes to most electric rate classes effective January 1, 2025. 

Why are the rates changing?

CMLP charges electric customers what it costs to buy electricity and operate the distribution grid in Concord. The market price for electricity fluctuates while distribution costs generally increase with inflation. Each year CMLP sets new rates that are designed to recoup these costs.

In 2025 the cost to produce electricity is expected to decline by almost $1 million dollars, due in part to lower natural gas prices from a warm winter last year and a warm start to this winter. CMLP’s fixed costs are down as well by about $300,000. Capacity costs are largely unchanged. The cost to transmit power, however, is expected to increase significantly by $1.5 million. As new sources of generation are added to the grid, transmission facilities must be built to bring the new sources to the load centers. The independent New England system operator of the electric grid, the not-for-profit corporation responsible for keeping electricity flowing across the six New England states, determines transmission rates under the Federal Energy Regulatory Commission’s oversight.

Other factors affecting the cost to customers are a need to trim trees in Town this year; an increase in salaries resulting from the Town's annual pay plan and Personnel Board approved merit and equity adjustments; and planned debt and interest payments for solar and energy storage at the middle school, which was voted by Town Meeting in 2023.

Any questions regarding these adjustments should be directed to Laura Scott, Power Supply and Rates Administrator, 978-318-3102.

Electricity is sold in units called kilowatt-hours, with each kilowatt being equal to 1000 watts. When one kilowatt (kW) is used for an hour, the energy used is called one kilowatt-hour (kWh). For example, ten 100-watt light bulbs running for one hour equals one kWh.

You have several options for paying your bill:

- Paying at CMLP, which is located at 1175 Elm Street. 

- For payments after business hours, there is a slot to the right of the front door of the Concord Town House.

Only if you are paying online.
