States tighten regulatory oversight for data centers as electricity demand continues to rise

The rapid growth of AI is reshaping electricity demand across the United States, prompting policymakers to take a closer look at the impact of Data Centres on grid reliability and customer costs. More than a dozen states are now considering new legislation, while over 100 local data center moratoriums are already in place as regulators seek to balance economic development with the need for a secure, affordable energy system. Matt Stasium comments on recent action across New York and New Jersey.

New York Pauses Large Data Center Development

On July 14, New York Governor Kathy Hochul signed an executive order establishing the nation's first statewide moratorium on new data centers with loads of 50 MW or greater. The temporary pause, which could last up to one year, allows the state to develop new energy and environmental regulations before additional large-scale facilities move forward.

The executive order also directs Empire State Development to establish a community investment framework within 60 days, requiring data center developers to contribute funding toward energy affordability initiatives and public service improvements. Governor Hochul also announced plans to eliminate tax incentives for hyperscale data centers, signaling a broader effort to ensure future development delivers tangible benefits to local communities.

New Jersey Focuses on Cost Allocation and Grid Planning

Just one week earlier, on July 7, New Jersey enacted legislation designed to better manage the impact of large data centers on the electric grid while strengthening oversight of transmission investments.

The new law creates a dedicated electric rate class for data centers larger than 50 MW, requiring them to bear the costs associated with the infrastructure needed to support their operations. Qualifying facilities must generally commit to paying for at least 85% of their requested electric service for 10 years unless they provide operational flexibility or bring new generation or capacity resources online.

The legislation also establishes a first-of-its-kind framework allowing data centers to offset capacity obligations by investing in demand-side resources, including energy efficiency, demand response, and behind-the-meter energy storage.

Beyond data center policy, New Jersey has increased state oversight of local transmission projects and removed a financial incentive previously available to utilities for voluntary participation in PJM, reflecting the state's broader focus on improving affordability and long-term grid planning.

A Growing National Trend

The actions in New York and New Jersey are part of a broader national movement as states grapple with the rapid growth of AI-driven data centers and their impact on electricity systems. According to the National Conference of State Legislatures, lawmakers in 15 states are considering measures that would pause or restrict new data center projects while officials assess their effects on electric grids, local communities and economic development.

Although most proposed projects are ultimately expected to move forward, policymakers are increasingly requiring developers to demonstrate how new facilities will support grid reliability, contribute to infrastructure investments, and minimize impacts on existing customers.

As electricity demand continues to rise, particularly across competitive wholesale markets such as PJM and NYISO, regulatory frameworks like these are likely to play an increasingly important role in shaping where and how future data center development occurs. customers.
