Gov. Mikie Sherrill on Monday signed the Power New Jersey Act, a law designed to open a regulated path for additional nuclear generation to enter the state's power mix — a move she says could help ease high electric bills for New Jersey residents.
The legislation establishes a competitive process for developers of new nuclear projects. Under the law, any company seeking to build in New Jersey must secure federal funding, obtain approval from the state Board of Public Utilities and demonstrate the economic or reliability benefits of its project before construction can begin.
What changes for residents
Supporters say adding more nuclear capacity could increase competition among suppliers and ultimately pressure electric rates downward. The state already relies heavily on existing reactors in the south, and backers frame the new law as a means to preserve and expand a low-carbon, baseload source of electricity.
“This bill creates a competitive process to build new nuclear projects that can power hundreds of thousands of homes," said Gov. Sherrill.
Sherrill campaigned on relief from high electric bills and has been advancing energy measures since taking office. The bill signing follows an April decision to lift New Jersey’s moratorium on additional nuclear power, clearing the way for this fresh regulatory framework.
Current role of nuclear in New Jersey
Three reactors in southern New Jersey now supply a substantial share of the state's electricity. The new law does not mandate construction; rather, it creates the state-level approval and competitive structure through which new projects can be proposed and evaluated.

How the approval process will work
- Developers must secure any applicable federal funding.
- Projects require approval from the Board of Public Utilities.
- Companies must demonstrate clear benefits before construction is authorized.
The law aims to ensure that proposed projects are financially viable and in the public interest before taxpayers and ratepayers are exposed to cost or reliability risks. Officials have framed the measure as creating more competition in procurement of large-scale capacity, although the precise timeline for any new builds will depend on proposals from developers and the pace of federal approvals.
Advocates of expanding nuclear capacity point to its ability to supply steady, low-carbon electricity; critics have in other contexts raised concerns about cost, waste storage and long regulatory timelines. The new state law primarily sets procedural and regulatory conditions needed for projects to move forward in New Jersey.
Residents concerned about potential rate impacts, siting or environmental safeguards will have opportunities to follow review processes at the Board of Public Utilities as proposals emerge under the new framework.
The governor’s signature marks the next step in New Jersey’s evolving energy policy, emphasizing a role for advanced nuclear alongside other resources as the state seeks to balance affordability, reliability and emissions goals.
