Overview

PJM Interconnection is the regional transmission organization for 13 states + DC, serving ~65M customers and operating the largest US grid by load. PJM has emerged as the canonical operator-side voice on AI/cloud data-centre demand: on May 6, 2026 it published a white paper warning that current generating capacity cannot absorb projected data-centre load and that the bottleneck is on the order of “years, not decades.” The interconnection queue holds 220 GW of new requests, with data centres as the dominant driver.

Timeline

  • 2026-05-09-AI-Digest — PJM publishes a May 6 white paper warning that “the current situation is not tenable”; CEO David Mills writes in the foreword that the bottleneck is on the order of “years, not decades.” Interconnection queue holds 220 GW of new requests with data centres as the dominant driver. PJM has separately moved to ratchet down its prior AI-demand forecasts (earlier load projections were apparently overstated), and FERC has directed PJM to create new rules for AI co-located generation. Structural attribution is broader than “AI” alone — combined cloud + AI data-centre load plus renewable transition, and treated as PJM-region-specific (Virginia / Ohio / Pennsylvania) rather than US-wide.

Key Developments

  1. “Years, Not Decades” Framing: CEO David Mills’ foreword frames the grid bottleneck as a years-scale rather than decades-scale problem. The phrasing is the load-bearing line for the May 9 grid story and is now the canonical timebox for AI-data-centre permitting urgency.

  2. 220 GW Interconnection Queue: The interconnection queue holds 220 GW of new requests, with data centres as the dominant driver. The figure quantifies the supply-side shortfall against Anthropic/xAI/Google 7-year compute deals signed at the same scale.

  3. Forecast Ratchet-Down: PJM has separately moved to ratchet down prior AI-demand forecasts; earlier load projections were apparently overstated. The honest read is that PJM is calibrating both the supply-side shortfall and the demand-side estimate — neither side is settled.

  4. FERC AI Co-Located Generation Rules: FERC has directed PJM to create new rules for AI co-located generation. The regulatory machinery is at least one cycle behind the deal flow — same theme as Simon Willison’s May 7 note on the Colossus 1 gas-turbine permitting.

  5. PJM-Region-Specific Strain: White paper names combined cloud + AI data-centre load plus renewable transition, and treats the strain as PJM-region-specific (Virginia / Ohio / Pennsylvania) rather than US-wide. The structural attribution is narrower than the headline “AI breaks the grid” framing.
