PJM Proposes FERC Rules to Curtail Unpowered AI Data Centers
Grid operator introduces Interim Resource Adequacy Service as data centers drive 30 GW demand surge
PJM Interconnection has formally submitted a regulatory framework to the Federal Energy Regulatory Commission (FERC) to manage grid interconnection for large data centers. The proposal creates specific operational rules for facilities that fail to bring their own dedicated power generation, protecting residential consumers during grid emergencies.
Key details
Under the proposed Interim Resource Adequacy Service (IRAS), PJM will establish new emergency procedures for large load customers that do not bring dedicated power supplies or secure capacity through Reliability Backstop Procurement. During severe grid stress or supply shortfalls, utilities will be directed to curtail or reduce electricity demand from these unsupplied large load facilities before taking any emergency actions that affect traditional or residential consumers.
To administer the framework, PJM will establish and maintain a Large Load Registry to track existing and new large electrical loads across its 13-state footprint. PJM reports that of the 32 GW in total forecasted electricity demand growth between 2024 and 2030, 30 GW—over 93 percent—is directly driven by hyperscale AI and data center development. The IRAS rules are intended to address operational issues ahead of anticipated capacity shortfalls starting in June 2027.
Why this matters
The proposal establishes a clear operational distinction between self-powered data centers and those relying entirely on public utility grids. By placing unpowered data centers first in line for emergency curtailment, PJM creates a strong regulatory and financial incentive for AI infrastructure developers to fund and deploy their own generation capacity, such as behind-the-meter natural gas, nuclear, or storage assets.
Context
PJM Interconnection coordinates electricity transmission across 13 states and the District of Columbia, serving over 65 million people in key data center hubs such as Northern Virginia and Pennsylvania. Recent capacity auctions in PJM saw prices hit statutory maximum caps due to soaring data center interconnection requests. PJM's filing follows similar initiatives in states like Pennsylvania and Texas that seek to protect residential ratepayers from the immense infrastructure costs and reliability risks associated with hyperscale computing.
Risks and open questions
It remains uncertain whether FERC will approve the IRAS framework without modifications or if data center operators will challenge the emergency curtailment hierarchy in federal court. Additionally, state public utility commissions will need to evaluate whether local distribution rules align with PJM's new Large Load Registry and emergency curtailment directives.
What happens next
FERC will review PJM's filing and receive public comments from state regulators, utilities, and industry stakeholders. If approved, PJM will begin populating the Large Load Registry and working with electric distributors to update regional emergency load-reduction plans prior to the June 2027 capacity adequacy benchmark.
