Overview

The Federal Energy Regulatory Commission (FERC) is an independent US federal agency that regulates the interstate transmission of electricity, natural gas, and oil. FERC’s authority over interstate electricity transmission, RTO market structures, and interconnection rules makes it the federal-regulatory layer of the AI Buildout Grid Constraint. FERC’s December 18, 2025 order directing PJM to overhaul rules for co-located and behind-the-meter large loads is the first major federal-regulatory acknowledgment that hyperscaler demand cannot be accommodated through traditional grid-interconnection mechanisms.

Key Facts

  • Independent agency: Five commissioners appointed by the President with Senate confirmation; serves staggered five-year terms; bipartisan composition required.
  • Authority over RTOs: Regulates Regional Transmission Organizations (RTOs) including PJM, ERCOT (limited), MISO, SPP, ISO-NE, NYISO. Approves tariffs, interconnection rules, and market structures.
  • December 18, 2025 PJM order: Directed PJM to overhaul rules for co-located and behind-the-meter large loads — first major federal-regulatory action explicitly addressing the hyperscaler vertical-integration / on-site-generation pattern. Microsoft Electricity Cost Recovery Commitment — POWER Magazine - 2026-01-22
  • Form 715: Annual transmission planning report filed by transmission-owning utilities; primary public document on transmission infrastructure.
  • Order 2023: Generator interconnection reform (issued July 2023, predates this entity page); intended to address queue backlog through cluster-study procedures and stricter financial commitments.

Newsletter Relevance

FERC sits at the federal-regulatory layer of the AI Buildout Grid Constraint. The December 2025 PJM order is the first major federal recognition that hyperscaler demand patterns (co-located generation, behind-the-meter arrangements) require regulatory adaptation. Any analysis of grid-capacity bottlenecks must reference FERC because the regulatory rules FERC sets — interconnection procedures, market structures, transmission planning — determine the rate at which the queue actually clears. For the May 15 article, FERC is supporting context: the PJM-order datapoint shows that even regulators recognize the queue mechanism is failing.

Open Questions

  • What is the timeline for PJM’s response to the FERC December 18, 2025 order? When does PJM submit revised tariff language?
  • Have other RTOs (ERCOT, MISO) faced similar FERC orders, or is this PJM-specific because of the Northern Virginia data-center concentration?
  • What is FERC’s posture on the parallel state-level cost-recovery debates (PJM-region governors’ January 15 2026 Statement of Principles)?
  • How does FERC’s Order 2023 (generator interconnection reform) interact with the new co-located/behind-the-meter rules? Are they coherent or in tension?
