MMWEC, CET Awarded Grant for Inclusive Utility Investments Program

Ludlow, MA – May 6, 2024

Massachusetts Municipal Wholesale Electric Company (MMWEC) and its energy efficiency provider and partner, CET, are pleased to announce the receipt of a grant to help support decarbonization of the residential sector.

MMWEC is working with CET on CET’s Inclusive Utility Investment (IUI) program. The IUI program, already successfully piloted for customers of MMWEC Member Ipswich Electric Light Department (IELD), is an innovative financing program that enables more residents, including renters, to decarbonize their living spaces at a price they can afford.

MMWEC and CET have received a grant of more than $75,000 through the American Public Power Association’s Demonstration of Energy and Efficiency Developments (DEED) program to make the program available to more municipal light plants (MLPs). The project will provide support to a cohort of two to three MLPs for launching IUI programs.

Inclusive Utility Investment

Under IUI, sometimes known as tariff on-bill financing, the resident who upgrades their home’s electrification or efficiency measures pays a monthly tariff that sums to no more than the savings in energy costs afforded by the new measures. The tariff is tied to the electric meter, rather than the resident, so that if a resident moves, the tariff simply transfers to the next occupant.

Unlike traditional on-bill financing, where a utility makes a loan to a property owner, thus requiring adequate credit history and a willingness to take on debt, IUI decouples capital improvements from the individual resident or business. It is a financing mechanism that enables upgrading properties with measures that reduce operating costs and improve the comfort, health, and environmental footprint of the building, all with little or no upfront capital investment from the ratepayer.

As part of the project, MMWEC will conduct a feasibility study of implementing MMWEC’s unique pooled loan program as a capital
pool for MMWEC Member light departments that launch IUI programs. This pooled loan funding would leverage economies of scale
and eliminate the substantial time and resources involved in each individual MLP independently sourcing capital.

What excites me about IUI is that it avails equitable access to clean energy improvements for all customers—renters and low income included—and has the potential to unlock the pace and scale of residential decarbonization that science-based targets
require,” says

IUI addresses one of the key hurdles to decarbonizing and electrifying the residential sector – up-front cost.” We are excited to continue our work with CET to expand the
availability of this program to more municipal utility customers. The IUI program is an effective tool to enable more people to
decarbonize their homes without breaking the bank.”
