PJM: Large Load definition and registry accepted by FERC; capacity and curtailment rules rejected (ER26-3515)

Reporting or resource-use requirement

In effect This instrument is recorded as currently in effect as of the dataset date.

Summary

On 9 October 2026 the Federal Energy Regulatory Commission accepted, effective 12 October 2026, PJM's definition of a Large Load at a cumulative peak of 50 MW and a Large Load Registry that requires load-serving entities to report on the Large Loads they serve, which the order says covers all such loads regardless of in-service date. It rejected the rest of PJM's filing, including its Interim Resource Adequacy Service, and directed a compliance filing within 30 days. The filing cited data center load growth.

Scope

Federal Energy Regulatory Commission order 197 FERC ¶ 61,019 (Docket ER26-3515-000) accepts in part, effective 12 October 2026, PJM's definition of a Large Load, set at a cumulative peak of 50 MW, and a Large Load Registry under which load-serving entities must give PJM information about the Large Loads they serve, with only aggregate data posted publicly. The order rejects the rest of the filing, including the Interim Resource Adequacy Service and Bring Your Own New Capacity rules, so no curtailment framework was accepted.

Covered jurisdictions

This instrument is stored once. It appears on the policy page of each jurisdiction below in a separate federal and multistate section and is not counted in any jurisdiction's own records, in-effect totals or map shading. Territorial coverage does not establish that an instrument applies to any particular site, utility or project.

How this list was set, checked 3 November 2026: PJM says it coordinates wholesale electricity in all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia. It does not say which are covered only in part, so every listed jurisdiction is marked as covered in part; that is not a finding that any of them is not wholly covered. Coverage source

What this does not establish

  • The order accepts the definition and registry but rejects the tariff text as filed because it includes language on the rejected frameworks, and directs PJM to file corrected text within 30 days. That compliance filing and any order on it were not reviewed.
  • PJM's Large Load page still labelled the registry and the service Pending FERC Approval when checked on 3 November 2026, while linking to this order. The Commission's order is the controlling record here.
  • The copy opened is the order as posted on PJM's site. The order names no list of states; the coverage list comes from PJM's description of its region and does not establish that the registry applies to any particular site, utility or project.

Unresolved questions

  • Whether PJM refiles an alternative to the rejected Interim Resource Adequacy Service, which the order says it may consider.

Relationships

Supersession means a later instrument replaces the earlier legal effect. Repeal links identify the repeal instrument and the measure it ends. A later implementation or related letter is not treated as a replacement unless the record says so.

  • No related action is recorded.
