Massachusetts -May 13, 2025
On May 13, Governor Healey unveiled a bold, $10 billion blueprint for an affordable, equitable clean energy future in Massachusetts, the Energy Affordability, Independence, and Innovation Act. Among its key features? A mandate for investor-owned electric utilities to implement Inclusive Utility Investments (IUI)—a model proven to remove the biggest barrier to building decarbonization: upfront cost.
At CET, we’re celebrating this moment—not just because it’s historic, but because we’re ready.
Over the past two years, we’ve built the technical, operational, and policy foundation for IUI programs in Massachusetts. And we didn’t just study it—we piloted it, with real customers, real savings, and real system benefits.
We’ve Done the Work
In partnership with Ipswich Electric Light Department and with support from the Massachusetts Clean Energy Center, CET led a feasibility study and program design for an IUI model tailored to Massachusetts’ climate, housing stock, and energy markets.
The results speak for themselves:
Read the study & coverage
Since completing our first Inclusive Utility Investment (IUI) feasibility study, IUI has only gained momentum. CET has partnered with several municipal utilities across Massachusetts—each actively developing or preparing to launch IUI programs. We’ve partnered with the Massachusetts Municipal Wholesale Electric Company (MMWEC) and Barr Foundation in this effort.
Massachusetts Leads—Now Let’s Make It Official
Massachusetts has never waited for change—we lead it. From enacting the Global Warming Solutions Act and setting some of the most ambitious legally binding emissions limits in the country to establishing the nation’s first Climate Chief cabinet position, the Commonwealth has consistently sought to turn a bold climate vision to reality.
With the Governor’s proposal, Massachusetts has the chance to do something historic: become the first state to mandate and scale IUI statewide. That would transform local pilots into a coordinated statewide solution—one that accelerates home decarbonization, drives equitable investment, and helps meet our emissions reduction goals.
