PJM's Data Center Crisis: 9 Grid Operator Bulletins That Tell the Story of America's Biggest Electricity Challenge
Between January 2023 and January 2026, PJM Interconnection — the grid operator serving 67 million people across 13 states — published 9 bulletins that trace its escalating struggle to integrate data center demand. What started as a load forecast noting “growth fueled by data centers” culminated in a DOE emergency order directing data center backup generators to run during Winter Storm Fern. This is the first primary-source timeline tracking how America's largest grid operator went from monitoring a trend to managing a crisis — told entirely through PJM's own words.
The Escalation Timeline
Load Forecast Predicts Data Center-Driven Growth
PJM's 2023 Long-Term Load Forecast projects 1.4% annual net energy growth and higher winter peaks, driven primarily by data center proliferation in Northern Virginia and Ohio.

PJM Board of Managers launches accelerated initiative to address reliability concerns from rapid large load growth. "Fast-track" language signals urgency — a departure from PJM's typically deliberative process.
Source: PJM Inside Lines →Dedicated Initiative to Balance Reliability with Load Growth
PJM formally kicks off multi-stakeholder initiative specifically addressing the tension between data center interconnection speed and grid reliability requirements.

PJM presents data center challenges at FERC's Annual Reliability Technical Conference. The issue is now a federal regulatory priority.

PJM formally tells FERC that colocated load growth (data centers connected directly to generation) "requires guidance" to manage reliability risks, costs, and market impacts. This is PJM asking the regulator for help.

PJM Board of Managers outlines a series of actions for 2026 to address "multiple challenges" of integrating data centers while preserving reliability and affordability for 67 million existing customers.

During Winter Storm Fern, the U.S. Department of Energy issues Section 202(c) emergency order directing customer-owned backup generation at data centers to operate. This is the first federal emergency order directly tied to data center electricity demand.

| Capacity Price (RTO) | $28.92/MW-day | $269.92/MW-day | $329.17/MW-day |
| Capacity Price Change | Baseline | +833% | +1,038% |
| PJM Response Level | Monitoring | Board Action | DOE Emergency Order |
| Interconnection Queue | ~260 GW pending | Process reform launched | Cycle 1 complete |

What the ISO's Own Words Reveal
Reading PJM's 9 bulletins in sequence reveals a clear pattern of escalation. The language shifts from analytical (“load forecast predicts growth”) to urgent (“fast-tracks effort”) to regulatory (“requires guidance from FERC”) to emergency (“Section 202(c) order”).
Key linguistic markers:
- Jan 2023: “Growth fueled by data centers” — observational language, part of a routine annual forecast.
- Aug 2024: “Fast-tracks effort” — urgency language. PJM rarely uses “fast-track” in official communications.
- Nov 2024: “Requires guidance to manage reliability, risks, cost and market impacts” — PJM is asking FERC for help. This is the grid operator saying it cannot solve this alone.
- Jan 2026: “Section 202(c) order” — a federal emergency power. The last time DOE invoked 202(c) for PJM was during Winter Storm Elliott in December 2022.
What This Means for Commercial Electricity Buyers
The data center demand surge is not just a PJM infrastructure problem — it directly drives the electricity costs paid by every commercial and industrial consumer in the footprint. The mechanism is simple: more load competing for the same generation capacity = higher capacity auction prices = higher bills for everyone.
Strategic Implication
With PJM's capacity price cap extended through 2030 at $325/MW-day, there is a temporary ceiling on how much this demand surge can cost consumers. But when the cap expires, the underlying supply-demand imbalance — driven by data center growth — will still be there.
