New Jersey lawmakers have approved legislation directing the state's Board of Public Utilities to establish a dedicated tariff for data centers with a capacity of 50 megawatts or more, a move designed to prevent residential customers and small businesses from absorbing the infrastructure costs generated by large-scale computing facilities. The bill now heads to Democratic Governor Mikie Sherrill for final approval.

What the Bill Requires

The legislation places a range of obligations on data centers that meet the 50-megawatt threshold. Qualifying facilities must provide financial guarantees committing to take or pay for at least 85 percent of their requested service over a ten-year period.

They must also demonstrate that their proposed project is not being proposed elsewhere, a provision aimed at discouraging speculative applications from developers seeking grid access without firm development plans.

Data centers covered by the bill will be required to participate in demand response and flexibility programs.

During grid emergencies, large data center customers must be curtailed before residential customers, establishing an explicit hierarchy of protection that prioritizes households over commercial computing loads.

The bill also instructs the Board of Public Utilities to prioritize interconnection for data centers that make binding commitments to bring their own clean generation or storage resources to the grid, creating an incentive structure intended to push large load customers toward contributing to rather than simply drawing from the state's electricity supply.

How the New Bill Differs From Its Predecessor

The legislation that passed this month is considerably broader than the bill that came before it. A similar measure was originally proposed in June of last year by Democratic assemblymen Dave Bailey and Joe Danielsen.

That earlier bill was pocket-vetoed by then-Governor Phil Murphy, who did not sign it before his term ended.

The replacement bill, S731, differs in several significant ways. Where the original bill set the triggering threshold at 100 megawatts, the new legislation lowers it to 50 megawatts, bringing a wider range of facilities under the tariff's requirements.

The new bill also applies to both existing and new data center facilities, whereas the scope of the previous version was narrower.

Additionally, S731 aggregates facilities under common ownership or located on contiguous sites, treating them as a single large data center for the purposes of determining whether the threshold has been met.

This provision prevents operators from structuring their facilities to fall below the threshold by dividing capacity across technically separate but functionally related sites.

Assemblyman David Bailey Jr. said Sherrill's office was involved in drafting the latest version of the bill and expressed optimism that she would sign it into law.

A Growing Pattern Across State Legislatures

New Jersey's action is the latest in a series of state-level legislative and regulatory moves across the country aimed at managing how the costs of data center grid expansion are allocated.

The wave of activity reflects growing concern among utility regulators and elected officials that the rapid proliferation of large computing facilities is driving infrastructure investment that ends up being paid for by ordinary ratepayers rather than the commercial entities responsible for the new demand.

Last month, regulators in Oregon approved a new rate class for data centers and other large loads, a rule that is now in effect.

Before that, Oklahoma Governor Kevin Stitt signed legislation aimed at protecting ratepayers from rising utility and infrastructure costs associated with data center growth.

Florida's governor signed a similar bill that prohibited utilities from passing data center infrastructure costs to residential and small-business customers and required large-scale users to bear their full cost of service.

Ohio, North Carolina, and Virginia have also seen similar rules proposed and passed, reflecting how broadly the legislative response has spread across states with significant data center activity.

The Ratepayer Protection Framework

The underlying principle common to New Jersey's bill and the legislation passed in other states is that large commercial electricity consumers should not be subsidized through cost socialization that spreads their infrastructure expenses across the general ratepayer base.

As data centers have grown in size and number, utilities have faced pressure to build out transmission and distribution infrastructure at a pace and scale driven largely by the needs of a single category of industrial customer.

New Jersey's S731 addresses this by requiring that facilities meeting the threshold operate under a dedicated tariff structure administered by the Board of Public Utilities, effectively separating the cost accountability of large data center customers from that of residential and small business ratepayers.

The financial guarantee requirement, which locks operators into paying for a substantial share of their requested service regardless of actual usage, further reduces the risk that speculative or underutilized capacity commitments will generate stranded costs that could otherwise be passed along to other customers on the grid.
