The framework defines a 'Large Load' as any end-use customer with a cumulative peak load of at least 50 MW at a single site or within a one-mile radius, a threshold that captures virtually every hyperscale data center campus in PJM's territory\n\n.\n\n[[2]](https://natlawreview.com/article/pjms-proposal-ferc-targets-data-centers-and-other-large-load-customers)The first proposal, a Reliability Backstop Procurement, would launch a central capacity auction in the September–October 2026 window targeting 6,831 MW of new supply to fill the shortfall identified in the 2028/2029 Base Residual Auction. PJM set a volume-weighted price ceiling of $555/MW-day and would allow selected resources commitments of up to 15 years, with a latest in-service date of June 1, 2032 [3].\n\nThe second, an Interim Resource Adequacy Service, would require electric distributors to curtail new large loads that have not secured qualifying capacity resources before activating Pre-Emergency Load Management for other customers. The compliance deadline is June 1, 2027 [2]. Together, the proposals represent one of the most aggressive moves by a U.S. grid operator to link AI-driven load growth to actual generation buildout.\n\n## The Backstop Procurement Mechanism\n\nPJM's Reliability Backstop Procurement is designed to attract new generation to the grid through a hybrid approach: bilateral matching between new loads and generators opened in June 2026 and has already closed to new responses, while the centralized auction window runs from September 30 through October 21 [3]. Bid evaluation and results finalization will follow from October 22 through December 2, ahead of the December Base Residual Auction\n\n.\n\n[[3]](https://kilowattlogic.com/news/pjm-reliability-backstop-14-9-gw-bilateral-procurement-data-centers-april-2026)Backstop costs will be allocated to load zones and load-serving entities tied to incremental large-load additions. State regulatory authorities retain the option to direct allocation; absent state action, PJM defaults to a peak-load contribution methodology [3]. The $555/MW-day UCAP ceiling is intended to balance affordability with sufficient incentive for new generation investment.\n\nThe Board explicitly rejected the stakeholder-preferred alternative, concluding it 'would not provide sufficient assurance that capacity equal to the identified near-term shortfall would actually be procured' [2].\n\n## Curtailment Hierarchy for Large Loads\n\nUnder the Interim Resource Adequacy Service, the curtailment hierarchy is unambiguous: new large loads lacking qualifying supply are cut before PJM deploys Pre-Emergency Load Management—the tool currently used to manage demand across all customers during system stress [2]. This effectively creates a two-tier reliability structure, with unhedged data centers and other large loads bearing first-mover risk during capacity emergencies.\n\nStarting with the 2029/2030 delivery year, PJM will go further: incremental new large loads that have not secured supply will be removed from future capacity auction demand calculations entirely [3]. This means the grid operator will not procure capacity on behalf of loads that have not demonstrated their own resource adequacy—a structural shift from the historical model where load-serving entities collectively covered all demand.\n\nAffected customers will receive compensation when directed to reduce consumption, administered by electric distributors in coordination with state entities, mirroring existing demand-response program structures [2].\n\n## The Large Load Registry\n\nPJM will maintain a mandatory Large Load Registry to improve load forecasting and underpin both the backstop procurement and curtailment frameworks [2]. The 50 MW threshold captures not only hyperscale data centers but also large industrial facilities, though AI-driven data center load is the primary driver of the forecasted 70 GW demand increase by 2038\n\n.\n\n[[1]](https://www.datacenterknowledge.com/energy-power-supply/pjm-says-ai-data-centers-must-bring-capacity-to-earn-firm-service)The registry requirement adds a transparency layer that PJM has lacked: until now, the grid operator has relied on utility-reported forecasts that have consistently underestimated data center load growth. By requiring direct registration, PJM aims to reduce the forecasting gap that contributed to the 2028/2029 auction shortfall.\n\n## Impact on Data Center Operators\n\nFor hyperscalers and neoclouds operating or planning campuses in PJM territory—which spans Virginia's Data Center Alley, northern New Jersey, and the broader mid-Atlantic corridor—the framework creates a clear imperative: secure bilateral power purchase agreements, develop dedicated on-site generation, or accept subordinate grid access. The June 1, 2027 compliance deadline gives operators less than 11 months to demonstrate qualifying supply [2].\n\nThe proposals follow PJM's earlier compliance filing in February 2026 in response to FERC's December 2025 order on co-located data centers, which directed PJM to clarify how facilities with on-site generation can operate while maintaining grid reliability [4]. Taken together, the regulatory trajectory points toward a PJM footprint where large data center loads are treated as a distinct class of grid participant with higher self-sufficiency requirements.\n\nThe tariff changes remain subject to FERC approval. As PJM noted in its board decision, 'the tariff is not final until the federal regulatory process is complete' [3]. Operators and developers should track the FERC docket closely before incorporating the framework into site-selection or procurement budgets.\n\n## Grid Context\n\nPJM's action comes against a backdrop of tightening capacity markets nationwide. The grid operator's two most recent capacity auctions cleared below the system's reliability requirement, a historically unusual outcome driven by the collision of accelerating load growth and generation retirements [1]. Approximately 15 GW of generation has retired across PJM since 2022, largely coal and older gas units, while new interconnection requests—dominated by renewables and storage—face queue timelines stretching to the early 2030s.\n\nThe 70 GW demand forecast through 2038 dwarfs any previous load-growth cycle in PJM's history. For comparison, PJM's current peak demand is roughly 150 GW, meaning the projected additions represent a nearly 47% increase in just over a decade. Whether the backstop procurement and curtailment framework can bridge the gap until sufficient new generation clears interconnection queues is the central open question for grid reliability in the mid-Atlantic region.\n\n## Further sources\n\n[[1] Data Center Knowledge, 'PJM Says AI Data Centers Must Bring Capacity to Earn Fi… ↗](https://www.datacenterknowledge.com/energy-power-supply/pjm-says-ai-data-centers-must-bring-capacity-to-earn-firm-service)\n\n[[2] National Law Review, 'PJM's Proposal to FERC Targets Data Centers and Other Lar… ↗](https://natlawreview.com/article/pjms-proposal-ferc-targets-data-centers-and-other-large-load-customers)\n\n[[3] KilowattLogic, 'PJM Backstop Board Decision: $555/MW-Day Cap and Large-Load Rul… ↗](https://kilowattlogic.com/news/pjm-reliability-backstop-14-9-gw-bilateral-procurement-data-centers-april-2026)\n\n[[4] Foley Hoag, 'PJM Board Directs FERC Filing on Reliability Backstop Procurement … ↗](https://foleyhoag.com/news-and-insights/blogs/energy-and-climate-counsel/2026/july/pjm-board-directs-ferc-filing-on-reliability-backstop-procurement-and-interim-resource-adequacy-serv/)\n\nThe stories that matter, in one email.
