Low-Income Programs 

The state of Massachusetts is served by the Low-Income Energy Affordability Network (LEAN), which is a network of Community Action Agencies, public and private housing owners, government organizations and public utilities that work together to provide low-income efficiency solutions in the state. Through LEAN, Eversource and Columbia Gas of Massachusetts participate in the dual fuel Income Eligible Coordinated Delivery Core Initiative (formerly Low-Income Single Family and Low-Income Multi-Family), which serves customers at or below 60% of the state median income level for 1–4-unit buildings or buildings with 5+ units that have 50% of units are at or below 60% AMI. The initiative offers no cost measures such as lighting and smart strips, appliance replacement, water saving measures, insulation and air sealing, and heating system replacement.  

The program serves all income eligible customers that meet the program guidelines. Customers typically qualify for fuel assistance and other qualifying government assistance programs and the utility Discount Rate. Customers with a high WAP score and high energy burden are given priority. The initiative is implemented by local Community Action Program (CAP) Agencies and is integrated with the Department of Housing and Community Development’s (DHCD) Weatherization Assistance Program (WAP). There is also a statewide Energy Efficiency Advisory Council and an Income Eligible Best Practices Committee that provide guidance on income eligible utility-sponsored programs in the state.  

Customers typically qualify for fuel assistance and other qualifying government assistance programs and the utility Discount Rate. Customers with a high WAP score and high energy burden are given priority. CAP agencies leverage additional funding from the Department of Energy and DHCD for heating systems and health and safety repairs. CAPs leverage utility funds and WAP funds for repairs of health and safety measures such as knob and tube removal, asbestos removal, combustion safety, mold and moisture remediation, roof repair, pest remediation and others. Additionally, the City of Boston Credit Union became a Mass Save HEAT Loan Participating Lender by offering customers the opportunity to apply for 0% loans for the installation of qualified energy efficient improvements. 

In 2021, according to Eversource, it achieved 142,842 MWh in energy savings, while spending $30,567,314 on its low-income programs and serving 12,366 low-income customers. Data on spending, savings, and customers served for Columbia Gas of Massachusetts in 2021 was not available.  

Multifamily Programs 

Eversource offers a Residential Coordinated Delivery initiative, which includes services to single-family homes, including free-standing town homes, smaller multi-unit buildings, such as those with three stories or less, and larger multi-unit buildings, such as those with four stories or more, or with a centralized heating system. It offers energy assessments that identify all cost-effective efficiency improvement or replacement opportunities regardless of fuel source for market rate properties with four or more dwellings. Utilizing a “whole facility” approach, the assessments focus on a facility's thermal envelope (shell insulation and air leakage conditions) as well as lighting and mechanical systems. The program also assesses in-unit savings potential for tenants. Improvements that may be eligible for incentives include lighting upgrades/controls, occupancy sensors, water heating equipment, domestic hot water measures, programmable thermostats, insulation, air sealing, heating and cooling equipment upgrades/controls, ENERGY STAR appliances and other improvements as determined on a site-specific basis. Eligible measures for the program include insulation, air sealing, light fixtures, and hot water and heating equipment, as well as heating and cooling equipment, air compressors, and energy management systems. 

In 2019, according to Eversource, it achieved 12,610 Net Annual MWh Savings , while spending $16,315,962 in incentives on its multifamily programs and served 11,082 housing units. 

Columbia Gas of Massachusetts offers a Multifamily Buildings program, which provides whole building retrofits and partial payment for energy efficiency measure to units. Eligible measures include insulation, heating system replacement, air sealing, showerheads, and aerators. Savings, spending, and participation data for 2021 was not available.
