Your Utility: National Grid
Lowell is served by National Grid, a founding Mass Save partner. Every National Grid customer in Lowell can access heat pump rebates, free weatherization programs, and 0% HEAT Loan financing.

Energy Challenges in Lowell's Mill-Era Housing
Lowell's textile mill heritage created a city of triple-deckers, worker row houses, and dense multi-family buildings. These buildings are part of what makes Lowell a National Historic Park—but they weren't designed for modern energy efficiency.
Housing Stock
A National Historic Park city built around textile mills, Lowell's housing stock is dominated by triple-deckers, worker row houses, and multi-family buildings from the 1880s-1930s. The city has one of the highest percentages of renter-occupied housing in the state, with many buildings owned by small landlords.
Heating Systems
Oil and natural gas heating predominate, with many older systems running at 60-70% efficiency. Lowell's Merrimack Valley location brings colder winters than coastal communities, making insulation and heating upgrades especially cost-effective.

What are the income limits for free insulation in Lowell?
In Middlesex County, a single person earning under $47,520 or a family of four under $93,240 (60% of State Median Income) qualifies for 100% free insulation through Mass Save. Limits increase for larger households. Income verification is confidential and straightforward.
Is help available in Khmer, Spanish, or other languages for Lowell residents?
Mass Save provides multilingual support by phone at 866-527-7283. Many local contractors serving Lowell have bilingual staff, reflecting the city's diverse Cambodian, Latino, and Portuguese communities. Written materials and assessment reports can be requested in your preferred language.
I rent an apartment in Lowell. Can I get help with energy costs?
Yes. Renters can schedule a free home energy assessment and receive no-cost items immediately—LED bulbs, smart power strips, low-flow showerheads. For larger upgrades, your landlord must approve the work. Many Lowell landlords participate once they learn about rebates—Mass Save can contact them directly on your behalf.
Are Lowell's historic mill buildings eligible for Mass Save?
Yes. Converted mill loft apartments and residential units in historic buildings qualify for the same Mass Save rebates. For buildings with 5+ units, the commercial multifamily program offers even larger incentives. Building owners in Lowell's historic district can access rebates while maintaining the character of their properties.
My Lowell home uses oil heat. What are my options?
Oil-heated homes qualify for the highest heat pump rebates because the energy savings are greatest. Converting from oil to a heat pump in Lowell typically saves $1,500-$3,000 per year, and the savings are even higher here due to colder Merrimack Valley winters. Income-qualified rebates can cover up to $16,000 of installation costs.
Can I combine Mass Save rebates with fuel assistance in Lowell?
Absolutely. If you receive LIHEAP fuel assistance, you automatically qualify for Mass Save's enhanced rebate tier—no additional income verification needed. Community Teamwork, Inc. in Lowell helps residents access both programs simultaneously, plus weatherization through the federal WAP program.
