Marblehead Municipal Light Department

Some good news for your wallet this winter!

As colder weather approaches, Marblehead Municipal Light Department is introducing a winter residential rate discount designed to help customers save on their electric bills.

The discount will be in effect for December 2026, January 2027, and February 2027, with savings based on monthly electricity consumption:

First 500 kWh: A discount of 1 cent per kWh.

Usage above 500 kWh: A discount of 3.5 cents per kWh.

What does that mean for your bill? A household using 650 kWh could save approximately $10 per month, while a household using 1,650 kWh could save around $45 per month.

The discount will be applied automatically to eligible residential accounts, so there's no need to enroll or apply.

As your community-owned utility, our priorities are shaped by the people we serve, not shareholders. That means keeping electricity reliable and affordable.

With cooler weather settling in, now is a good time to think about keeping the heat inside your home.

Even small air leaks around windows, doors, and other areas of your home can add up, allowing warm air to escape and making your heating system work harder than it needs to.

If you're considering a heat pump, addressing those leaks and making sure your home is properly insulated can go a long way toward getting the most out of your investment.

Not sure where to start? We've put together a step-by-step guide to help Marblehead residents through the heat pump installation process, including home energy assessments, available incentives, and finding a qualified installer.

Your Home Could Be Costing You More Than You Think!

With colder weather approaching, now is a great time to take a closer look at your home's energy efficiency.

Hidden air leaks, inadequate insulation, and inefficient heating systems can quietly drive up your utility bills. A home energy audit can help identify these issues and recommend improvements that could save you thousands of dollars over time.

MMLD's NextZero program can help you take the first step toward a more comfortable, energy-efficient home.

⚡ TRIVIA TUESDAY ANSWER REVEALED! ⚡

The correct answer is B) 1907!

When Marblehead's first electric light plant opened in 1895, electricity was supplied to just 36 buildings, and operations followed a "moonlight schedule," with service influenced by the phases of the moon.

That all changed in 1907, when electricity became available in Marblehead 24 hours a day!

We've come a long way in nearly 120 years of around-the-clock service, but our commitment to keeping Marblehead powered remains the same.

Thanks to everyone who participated, and stay tuned for next week's Trivia Tuesday!

⚡ TRIVIA TUESDAY! (No cheating!) ⚡

Two weeks ago, we opened our doors to the community and shared a little of MMLD's history.

When Marblehead's first electric light plant (pictured here) began operating in 1895, it supplied electricity to just 36 buildings in town. Back then, the plant operated on a "moonlight schedule," meaning its hours were determined in part by the amount of natural light provided by the moon!

But here's today's question: In what year did electricity become available in Marblehead 24 hours a day?

A) 1905
B) 1907
C) 1910
D) 1912

FLASHBACK FRIDAY!

Earlier this week, we shared a photo of our MMLD line crew standing proudly in front of one of our bucket trucks.

A lot has changed over the years, from the equipment we use to the trucks that keep our crews moving. While the technology has evolved, our commitment to keeping Marblehead powered has remained the same!

We thought we'd have a little fun with a trip down memory lane.

Can you guess the year of each of these two MMLD trucks?

Take a close look at the photos and drop your guesses in the comments! Let's see who can come closest to identifying the year of each truck.

We'll reveal the answers in a future post!

Last week’s Public Power Week Open House was a great opportunity to showcase MMLD, but there’s one team we didn’t get to highlight—our line crew! ⚡

Rain or shine, day or night, our dedicated lineworkers are out in the field maintaining our electrical system, responding to outages, and keeping the lights on for Marblehead.

They’re the backbone of our operations and a big part of what makes public power so special: local people serving their own community.

We're proud of the work they do every day to keep Marblehead powered!

Special thanks for to our intern Bridget Knight and our Apprentice lineman Cece Pellizzaro for touching up and capturing these shots.

What a great day of community and public power! ⚡

Thank you to everyone who joined us for our MMLD Open House. Our 9 AM, noon, and 3 PM tours gave community members a chance to meet our staff and ask questions about everything from meter installations and power capacity to mutual aid and the history of the department.

We also took public power into the classroom! Our Distribution Manager and newest apprentice linemen visited third graders at Glover and Brown Schools to talk about the work we do every day to keep Marblehead powered.

We’re incredibly proud to be owned by the people of Marblehead and grateful for the community we serve.

Missed the Open House? Don’t worry — this won’t be the last one! ⚡
