Pennsylvania Signs Data Center Oversight Law as Northeast States Tighten Grid Rules
A wave of state-level legislation is forcing data centers to disclose power and water demands, reshaping how AI buildout intersects with grid planning across the PJM footprint.
Pennsylvania Governor Josh Shapiro signed a state budget on Sunday (2026-07-12) that requires data centers to report their annual water and electricity consumption to state authorities and mandates that PJM Interconnection provide Pennsylvania regulators with greater visibility into its demand forecasting process.4
For PJM, which already manages one of the world's largest grid interconnections, state-level oversight of demand forecasting creates a new layer of accountability at a moment when load growth projections are being revised sharply upward by AI and hyperscale cloud buildout. Pennsylvania's reporting requirements address the information gap rather than restrict buildout directly — a contrast with approaches taken elsewhere in the region.4
New Jersey moved in a parallel direction the week prior. Governor Mikie Sherrill signed legislation on Tuesday (2026-07-07) requiring state regulatory review of supplemental transmission projects — infrastructure additions that bypassed standard oversight and totaled $14.7 billion in ratepayer costs from 2008 to 2025, representing 79% of total transmission expenses in the state during that period. A separate bill requires utilities to be PJM members, tightening integration between state-level planning and regional grid operations.3
New Jersey also introduced an unusual mechanism for managing data center load growth. Under legislation signed the week of 2026-07-06, data centers can fund residential energy upgrades — heat pumps, solar panels, and batteries — as a pathway toward securing grid capacity. Enrolled households could begin receiving those upgrades as early as mid-2028, according to the Natural Resources Defense Council.6
New York moved more aggressively. Governor Kathy Hochul signed an executive order imposing a statewide moratorium on new large-scale data centers for up to one year, the first such action in the United States. The order freezes permitting for facilities requiring 50 megawatts or more. New York's grid is already contending with at least 28 large data center projects and a combined energy demand of 9.7 gigawatts currently under consideration.5
The moratorium sharpens a tension that has been building across the Northeast: grid operators and state regulators are struggling to square long-term resource adequacy with the pace at which hyperscale compute demand is arriving. New York's approach is a hard pause while the state assesses grid impact. Pennsylvania's is information-gathering. The two states share transmission infrastructure, and a project viable under Pennsylvania's disclosure framework faces a different calculus under New York's moratorium.5,4
The regulatory divergence carries direct implications for developers and utilities planning capital allocation across the PJM footprint. How PJM integrates Pennsylvania's new oversight role into its demand forecasting process will determine whether this becomes a meaningful planning constraint or a reporting formality.4,3
Developers facing state-level pressure are meanwhile exploring unconventional power arrangements. Developer Crusoe signed a $1.25 billion contract for 29 jet-engine turbines to run data centers nationally, while startup Panthalassa raised $140 million to build offshore data centers that generate power from wave motion.1 Both approaches are early-stage and do not directly relieve near-term grid stress, but they illustrate how constrained interconnection queues are pushing procurement strategies to the margins.
The political dynamic underpinning these moves is consistent across states. Large tech companies have historically operated outside the localized resource planning constraints that govern utilities and industrial load. State legislators are now demanding the same disclosure and approval frameworks applied to other large electricity consumers. In Wisconsin, residents of Janesville are expected to vote in November on a measure requiring municipal approval before tax incentives are offered for any new data center valued above $450 million.2
The near-term question for PJM grid planning is whether Pennsylvania's new demand-reporting requirements produce data that materially changes load forecasts in the region, and whether that information reaches interconnection queue decisions quickly enough to affect which projects are built and in what sequence. The New York moratorium will run for up to a year, meaning the state may face a period of suppressed large-load interconnection requests while adjacent states continue to process them — shifting the geographic distribution of AI infrastructure buildout in ways that will take time to appear in forward load data.4,5
