Overview
PJM Interconnection is the regional transmission organization (RTO) coordinating wholesale electricity across 13 states (DE, IL, IN, KY, MD, MI, NJ, NC, OH, PA, TN, VA, WV) plus DC. It serves more than 65 million people and operates one of the largest wholesale electricity markets in the world. As of 2026, PJM has become the load-bearing example of the AI-buildout-into-ratepayer-bills story.

- 2026/2027 BRA: PJM short 208.7 MW of reliability objective Quarterly State of the Market Report for PJM Q1 2026 — Monitoring Analytics - 2026-05-14
- 2027/2028 BRA: PJM short 6,516.6 MW of reliability objective Quarterly State of the Market Report for PJM Q1 2026 — Monitoring Analytics - 2026-05-14
- Data-center-load inclusion across the 2025/2026 + 2026/2027 + 2027/2028 BRAs added $23,100,955,341 in capacity-market revenue Quarterly State of the Market Report for PJM Q1 2026 — Monitoring Analytics - 2026-05-14
- Of that, $13,768,851,483 landed on customer bills across the 2026/2027 and 2027/2028 BRAs even with the “Agreement” VRR-curve cap in place; without the Agreement the impact would have been $26.85B Quarterly State of the Market Report for PJM Q1 2026 — Monitoring Analytics - 2026-05-14
- The “Agreement VRR curve” (restricted VRR) is the regulatory cap negotiated after Josh Shapiro and the Commonwealth of Pennsylvania filed a December 30, 2024 complaint against PJM (Docket EL25-46-000); PJM submitted the revisions Feb 20, 2025 (Docket ER25-1357-000) Quarterly State of the Market Report for PJM Q1 2026 — Monitoring Analytics - 2026-05-14
- Next BRA: June 2026 (same month as Warsh’s first FOMC, June 16-17). The IMM warns: “The price impacts will be even larger in the near term unless the issues associated with data center load are addressed in a timely manner, prior to the next BRA.” Quarterly State of the Market Report for PJM Q1 2026 — Monitoring Analytics - 2026-05-14

Newsletter relevance
PJM is the cleanest expression of AI Cost Incidence — the question of who pays when AI infrastructure demand outruns supply. The +398% Q1 capacity-cost figure landed on customer bills, not on hyperscaler balance sheets. The political response (governor threatening withdrawal) is the leading indicator that affordability framing will drive 2026 ratepayer-impact politics.

Open questions
- Will PJM’s 2029 capacity-price cap hold under continued AI demand growth, or will it surface as a procurement-shortfall mechanism instead?
- Does the Pennsylvania withdrawal threat have any procedural teeth, or is it pure political signaling?
- How does the $13B customer-bill incidence figure compare to the corporate-tax-receipts side of the AI buildout? (i.e., are hyperscaler tax payments to the same states offsetting any of the ratepayer transfer?)
