Pennsylvania Governor Josh Shapiro has signed a sweeping executive order that fundamentally reshapes how artificial intelligence data centers pay for grid upgrades, ending decades of cost-shifting that inflated electricity bills for ordinary residents. Executive Order 2026-05 establishes binding state compliance requirements for large-scale data center development, directly addressing a mounting affordability crisis driven by hyperscaler interconnection queues in the PJM Interconnection territory.

Why Are Data Centers Suddenly Costing Ratepayers Billions?

The numbers tell a stark story. Data center demand was responsible for $29.4 billion in capacity charges to ratepayers, or 46 percent of total auction costs, across PJM's last four base residual capacity auctions. To put that in perspective, nearly half of what everyday consumers pay for grid reliability is now going toward infrastructure upgrades driven by AI companies, not traditional utilities or households. With PJM projecting 74 gigawatts of summer peak load growth through 2045, Pennsylvania recognized that voluntary commitments from tech giants were insufficient to protect consumers.

The state's Department of Environmental Protection has received formal permit applications for only 20 data center facilities, yet reports indicate more than 100 proposals are in various stages of development across Pennsylvania. This gap between proposals and actual permits revealed a troubling pattern: companies were locking in grid capacity without transparent public scrutiny or binding financial accountability.

What Specific Rules Does Pennsylvania Now Enforce?

The executive order introduces a multi-layered regulatory framework that eliminates the loopholes tech companies previously exploited. Here are the core mechanisms:

• Consent Order and Agreement Requirement: Any data center seeking a permit for facilities exceeding 25 megawatts peak demand must enter into a formal, project-specific binding agreement with the state, codifying compliance with the Governor's Responsible Infrastructure Development (GRID) standards focused on energy affordability, community transparency, workforce development, and environmental protection.
• Removal from Fast-Track Permitting: Data center projects are permanently disqualified from Pennsylvania's PA Permit Fast Track Program, eliminating the expedited approval pathway that previously allowed companies to bypass rigorous environmental and community review.
• Conditional Tax Exemptions: The Department of Revenue must update the Computer Data Center Equipment Program to ensure that sales and use tax exemptions are strictly contingent upon compliance with the GRID framework, tying financial incentives directly to regulatory adherence.
• Ban on Non-Disclosure Agreements: State agencies are prohibited from executing NDAs with data center developers, ending closed-door utility and infrastructure negotiations that kept costs hidden from public view.
• Mandatory Annual Reporting: Beginning July 1, 2027, all operating data centers must submit detailed annual reports documenting monthly energy consumption, natural gas use, hourly peak load in megawatt-hours, water source and withdrawal volumes, waste-heat capture efforts, and on-site generation metrics.

How Does the Grid Curtailment Mandate Change the Game?

Perhaps the most consequential provision is the "first-to-curtail" mandate, which fundamentally reorders the priority hierarchy during grid emergencies. Electric utilities must revise their pre-emergency and emergency load control protocols to curtail data centers prior to any other customer class, unless the data center has procured incremental capacity covering 100 percent of its electricity demand. This means that when the grid faces stress, AI companies lose power first, not hospitals, schools, or residential neighborhoods.

Utilities are also explicitly barred from classifying data centers as "critical load" to exempt them from emergency grid curtailments, a designation that previously allowed tech companies to maintain uninterrupted operations while other sectors faced blackouts. Additionally, data center operators must now pay 100 percent of the interconnection costs incurred by utilities and bear direct financial responsibility for any PJM reliability backstop auction costs, with utilities prohibited from passing unpaid charges to general ratepayers in the event of a developer's insolvency.

Which Major AI Infrastructure Projects Are Affected?

The mandate heavily impacts behind-the-meter and co-located configurations, including Amazon Web Services' planned multi-hundred-megawatt deployment at Talen Energy's Susquehanna nuclear station, as well as potential restart initiatives like Constellation Energy's Crane Clean Energy Center at Three Mile Island Unit 1. Developers must now demonstrate complete additionality and ring-fenced local cost allocation to pass state scrutiny, meaning they cannot claim that their power comes from existing generation or that costs should be spread across the broader grid.

Regulated utilities, including PPL Electric Utilities, PECO Energy, and FirstEnergy subsidiaries, will face stringent Pennsylvania Public Utility Commission oversight regarding large-load interconnection filings and must participate in PJM's large load registry without socializing system upgrade costs. This shift transfers financial burden from ratepayers to the companies actually driving the demand.

What Does This Mean for the Broader AI Infrastructure Landscape?

Pennsylvania's regulatory pivot signals a potential turning point in how states approach hyperscaler development. The executive order explicitly notes that voluntary initiatives, such as the "Ratepayer Protection Pledge" signed by major artificial intelligence developers to build or buy new generation, remain legally non-binding, necessitating codified state intervention. This acknowledgment reflects growing skepticism about corporate self-regulation in an industry where financial incentives often conflict with public interest.

The order also instructs the Department of Environmental Protection to establish expedited pathways for clean generation, battery storage on brownfield sites, and advanced transmission technologies such as advanced reconductoring on existing rights-of-way. This creates a counterbalance: while data centers face stricter requirements, the state is simultaneously accelerating approval for renewable energy and grid modernization projects that could offset their power demands.

For independent power producers, utilities, and hyperscalers operating within the PJM footprint, Pennsylvania's framework establishes a new baseline for regulatory accountability. Companies can no longer rely on opaque interconnection agreements or cost-shifting mechanisms to make their projects economically viable. The transparency requirements, combined with the curtailment mandate and cost ring-fencing, force data center operators to internalize the true infrastructure costs of their operations, potentially reshaping investment decisions across the industry.
