As we head into cooler months, and with energy costs rising, now is a great time to check your home’s energy efficiency. The assessment is free, and you may be eligible for incentives through Mass Save®.
We’re dedicated to informing our customers of the benefits of public power versus investor-owned utilities like National Grid, and one of the major benefits is the difference in cost.
We understand that our customers want to save as much energy as possible to reduce their monthly electric bill. To assist in that effort, MMLD will be handing out free LED light bulbs!
As artificial intelligence reshapes workplaces, two demanding Massachusetts trades still rely on human judgment, technical skill, and physical endurance.

I had the pleasure to hike Mt Osceola and East Osceola for the flags on the 48 event. On this day each year, for the last 24 years, hikers carry the flag to all 48 4000+ foot mountain peaks in New Hampshire and display the flag from 12p until 2p in honor of those we lost on that day. It was a beautiful day and an honor to participate. We will never forget. ... See MoreSee Less
A Friendly Reminder About the Merrimac Municipal Light Department Prompt-Payment Discount:
We continue to receive questions from customers who expected to receive the monthly prompt-payment discount. We hope the following information helps clarify how the discount works. To qualify, MMLD must receive your payment no later than the 15th of the month. Please be aware that when you schedule a payment through your bank’s online bill-pay service, the bank mails us a paper check instead of transferring the funds electronically. Even if the money is withdrawn from your account on the 14th—or the check is dated before the 15th—the payment may not reach us until several days later. If we receive it after the deadline, the discount cannot be applied. To help ensure that you receive the discount, you may: • Schedule bank bill-pay early—preferably by the first of the month—if your bank mails paper checks. • Pay online at www.merrimaclight.com through the end of the day on the 15th. • Mail your payment early enough to arrive by the 15th: Merrimac Municipal Light Department 10 West Main Street Merrimac, MA • Bring your payment to our office at 10 West Main Street. • Use our 24-hour drop box. Payments deposited by 7:30 a.m. on the 16th will qualify for the discount. Please remember that the date written on a check does not determine eligibility; the discount is based on when MMLD receives the payment. We hope this clears up any confusion. Thank you for being such valued customers. We are proud to be your local municipal public-power provider! ... See MoreSee Less

As previously stated, Merrimac Light Department would provide an update once additional information became available regarding the town-wide power outage that occurred on August 18th.
Following discussions with National Grid and review by our engineering consultant, the outage was traced to two fuses associated with a recently installed National Grid metering installation. The fuses were not properly sized for the electrical load they were required to carry under certain system conditions. When Merrimac's backup power supply was called upon during the event, the two fuses operated, resulting in the outage and some customers experiencing “half power” or “single phasing”.
Since identifying the cause, Merrimac Light Department has identified measures that will be implemented to prevent a similar condition from affecting customers in the future. We are also continuing to work with National Grid to review the installation and implement any additional corrective actions that may be appropriate.
We understand that outages of this nature are disruptive and frustrating. We appreciate the patience and understanding of our customers while we worked to determine the cause. Merrimac Light Department remains committed to transparency, reliability, and keeping our community informed.
