New Jersey is advancing a bill that would require new data centers to supply their own electricity using low-carbon sources. The proposal aims to protect ratepayers as AI-driven demand grows, but it raises questions about feasibility, cost, and long-term grid impact.
New Jersey Proposes “Bring Your Own Power” Rule for Data Centers
New Jersey is moving toward a new approach for large electricity users. A state Senate committee has advanced bill S-680, which would require new AI and crypto data centers to supply their own power.
Under the proposal, new facilities would need to source electricity from new low-carbon generation such as solar, wind, geothermal, or nuclear. They would also be required to submit energy sourcing plans to the New Jersey Board of Public Utilities for approval.
A Regional Catch
The requirement is not automatic. It would only take effect if a majority of PJM states adopt similar rules. Without regional alignment, developers could shift projects to nearby states with fewer restrictions.
To support that coordination, the committee also passed SR-18, a resolution encouraging other PJM states to adopt comparable policies.
Why This Is Being Proposed
The policy is a response to rising demand and rising prices. PJM has warned that electricity demand, driven by data centers and large industrial loads, is growing faster than available supply. At the same time, New Jersey customers saw electricity bills increase by about 20% last year, following earlier increases of roughly 3.6% to 8.6% in 2024.
Lawmakers are linking those trends. If large data centers are driving new demand, the argument is that they should also be responsible for supplying the power required to serve it.
Scale of Data Center Demand
New Jersey already has as many as 116 data centers, with more planned. One proposed project in Vineland is expected to require around 300 MW of power, roughly enough to serve 65,000 homes, or about 2% of households in the state.
Demand at that scale puts pressure on both generation and transmission infrastructure.
A Shift in the Traditional Model
Historically, large users have relied on the grid to supply power. This proposal changes that dynamic. Data centers would still connect to the grid, but they would need to build or contract enough generation to match their demand.
The goal is to prevent the cost of new infrastructure from being passed on to existing ratepayers.
Concerns and Tradeoffs
Not everyone agrees with the approach. The New Jersey Business and Industry Association supports the concept but argues that requiring 100% low-carbon supply may not be practical at scale today, especially given the need for continuous, 24/7 power.
Others argue that the technology exists and that the real question is cost allocation. Who should pay for the generation and infrastructure required to support large new loads?
Long-Term Risk
There is also a longer-term consideration. If demand projections change and the AI-driven growth slows, new generation built specifically for data centers could become underutilized.
What Happens Next
Both S-680 and SR-18 now move to the full Senate. If passed and adopted across the PJM region, the policy could reshape how large electricity users connect to the grid.
At its core, the proposal reflects a broader shift in thinking. As demand grows, states are looking for ways to ensure that new load does not translate directly into higher costs for existing customers.
