Committee releases bill and companion resolution urging AI data centers to use new clean energy; debate centers on PJM grid and rate impacts

The Senate Environment and Energy Committee released Senate Bill 4143 and a related concurrent resolution (SR-125). The bill requires proposed artificial-intelligence data centers to submit an energy-usage plan to the New Jersey Board of Public Utilities and requires that electricity for AI data centers be derived from new clean-energy sources. The resolution urges other states in the PJM interconnection region to adopt similar requirements; it becomes effective only if a threshold of states agrees.

Supporters, including representatives of the Sierra Club, Environment New Jersey and Isles, argued that rapid growth of AI data centers threatens to increase electricity demand, raise consumer bills and worsen air quality unless new clean generation is additional to the existing grid. Taylor McFarland of the Sierra Club said the region’s interconnection backlog and PJM capacity-market problems mean data-center demand could exacerbate price increases and environmental impacts.

Environmental witnesses emphasized additionality — that power used by new AI centers should come from newly developed clean generation rather than reallocated existing clean resources that would otherwise serve ratepayers. Allison McLeod of the New Jersey League of Conservation Voters warned that pulling existing clean power into behind-the-meter arrangements can “backfill” the public grid with fossil generation.

Opponents — including the New Jersey Chamber of Commerce, the New Jersey Business and Industry Association and developers — said the bill’s planning and approval requirements could deter AI investment, duplicate other regulatory processes, and that natural-gas generation could be a lawful and practical source of new on‑site power. Ray Kanter (NJBIA) and Mike Egerton (Chamber) testified that developers already are deploying behind-the-meter solutions and that limiting allowable generation types to renewables and nuclear could be unnecessarily restrictive.

The committee considered the two measures together, adopted technical amendments, and released both on a roll-call vote. Sponsors and witnesses said further regional coordination with other PJM states will be necessary to prevent cost shifting across state lines.
