From Water Power to Clean Power
Lowell was built on renewable energy. In the nineteenth century, an intricate system of canals channeled the Merrimack River to turn waterwheels and turbines that powered the city's textile mills. Today, that legacy is being reimagined. Solar arrays now cover rooftops of former mills, battery storage projects support the grid, and UMass Lowell research centers are helping solve challenges in wind and solar technology.
Massachusetts has ambitious climate goals, including net zero emissions by mid-century, and incentive programs such as the SMART solar program and Mass Save rebates make clean energy more accessible. For Lowell homeowners, businesses, and institutions, choosing the right renewable energy partner can reduce costs, increase resilience, and support a cleaner future.

Renewable Energy Trends in Lowell
Battery storage is one of the fastest-growing segments, driven by incentives and a desire for backup power. Heat pumps are replacing oil and gas heating systems, often paired with rooftop solar. Community solar allows renters and condo owners to benefit from clean energy without installing panels. Universities and businesses are setting their own sustainability goals, increasing demand for on-site renewables and renewable energy purchasing.
Lowell's historic mills are also being studied for creative applications, including rooftop arrays, canal-based hydropower, and microgrid designs that improve resilience for critical facilities.
How to Get Started
Begin with a home or building energy assessment, often available through Mass Save. Gather your recent utility bills and note your roof's age and orientation. Request multiple quotes and compare equipment, warranties, and financing terms. Ask installers about permitting timelines with the city and interconnection with the local utility.
Frequently Asked Questions About Renewable Energy in Lowell
Can renters benefit from renewable energy?
Yes. Community solar subscriptions and municipal aggregation programs with added renewable content allow renters to support clean energy and, in some cases, save on electricity without installing equipment.
Is battery storage worth it?
Batteries provide backup power during outages and can earn incentives for supporting the grid during peak demand. For homes with medical equipment, home offices, or frequent outages, storage can be especially valuable.
Do historic buildings limit renewable options?
Historic districts may have design guidelines, but many mill buildings have flat roofs ideal for solar that is not visible from the street. Early coordination with city officials helps projects move smoothly.
How do businesses benefit?
Businesses can lower operating costs, hedge against price volatility, meet sustainability commitments, and take advantage of tax incentives. Many developers offer power purchase agreements with no upfront investment.
