How will New England keep the lights on, energy bills manageable, and the electric grid reliable as demand continues to grow?
That question brought together over 500 policymakers, energy experts, community leaders, and industry representatives at the New England Regional Nuclear Policy Summit. This Summit was not the first action but rather another mindful step state officials have taken over the last two years. Nuclear’s history runs deep in New England. Its story isn’t over and as all six governors showed when signing the letter to support nuclear and to coordinate as a region on future nuclear deployment, the next chapter is currently being written.
The stakes are significant. New England may need about 30 gigawatts of additional electric capacity to meet future demand anticipated by 2050. Several of the region’s states also have climate goals to achieve no later than 2050 – nuclear energy is a willing partner to accomplish both.
New England’s two operating nuclear plants already produce about one quarter of the region’s electricity. Natural gas and oil supply roughly half, and imported energy, including hydropower, remains critical. Even as the region adds more wind, solar, and battery storage, summit speakers emphasized that New England will still need dependable power that is available when the sun is not shining and the wind is not blowing.
Speakers explained that adding nuclear could reduce the need to overbuild other generation sources, along with the transmission lines and supporting infrastructure needed to connect them to the grid. That could have important implications for reliability, land use, and, most importantly, ratepayer costs.
Building new reactors, however, is not simply a matter of choosing a technology. States and developers must manage construction costs, strengthen supply chains, create a skilled workforce, and protect customers from unnecessary financial risk. Presenters pointed to Ontario’s planned four-reactor project as an example of how building multiple units in sequence can allow lessons learned from the first unit to improve those that follow.
Public trust will be just as important as financing and engineering. Waterford, Connecticut, home to the Millstone nuclear plant, offered a practical example of how strong relationships between plant operators and surrounding communities can support safety, emergency preparedness, and local economic development. Summit speakers stressed that communities should be involved early and continuously in conversations about potential projects.
Across New England, those conversations have been ongoing over the last several years and have already begun to show promise. New Hampshire and Massachusetts are developing state nuclear road maps. Rhode Island has revised its renewable energy policy to allow nuclear participation and is considering partnerships with existing plants. Vermont is exploring legislative changes and the potential use of available transmission capacity at the former Vermont Yankee site. Connecticut and Massachusetts are focused on workforce and supply-chain needs, while Maine Maritime Academy has received federal funding to advance its nuclear program.
The region is also pursuing a multi-state nuclear procurement study, evaluating potential sites, and working to better define its future electricity needs. New England has shared the costs of regional energy infrastructure before, and speakers suggested a similar approach could help make nuclear projects possible.
The summit’s message was simple: “Six states, one grid, a shared energy future.” Turning that vision into reality will require coordination, transparency, and sustained public engagement. But New England’s nuclear conversation is clearly moving from whether the technology should be considered to how the region can evaluate and build it responsibly.
