PJM
Already under a December 2025 co-location order with a compliance filing accepted in part in June 2026. Exempted from some directives other regions received under the June 18, 2026 show-cause. Intervention window closed July 9, 2026.
Largest U.S. market and the data-center epicenter, but a looming capacity shortfall, a queue mid-overhaul, and intense political heat over ratepayer cost-shifting make timing and cost uncertain.

- Generation queue notes
- PJM has moved to a first-ready, first-served annual cycle process. Cycle 1 closed Apr. 27, 2026 with 811 new generation projects totaling 220 GW, and PJM stated there was no remaining backlog from prior queues. The Reliability Resource Initiative selected 51 projects totaling 9,361 MW UCAP, and FERC approved a temporary Expedited Interconnection Track for up to 10 large capacity-resource requests per year.
- Large-load posture rationale
- FERC's December 2025 order forced PJM to create transparent co-location rules; PJM filed compliance Jan/Feb 2026. PJM classifies large load as 50 MW+ in forecasting. Projected 6-15 GW capacity shortfall by 2027-2030 is the core tension.

Editorial analysis- Tier
- Mixed
- Rationale
- Largest U.S. market and the data-center epicenter, but a looming capacity shortfall, a queue mid-overhaul, and intense political heat over ratepayer cost-shifting make timing and cost uncertain.
- What's working
- Queue is moving again under Cycle 1; 811 projects totaling 220 GW submitted into the first reformed-process intake.
- Clear FERC-mandated co-location framework gives developers a defined (if costly) path.
- What's working against
- Projected 6-15 GW capacity shortfall by 2027-2030 against surging data-center demand.
- Bipartisan governor and White House pressure to make data centers bear their own infrastructure costs raises cost risk.
- One thing to watch
- FERC's June 2026 national large-load rule (RM26-4-000), which uses PJM's co-location order as a template.
- Analyst note
- PJM is where the most data-center demand wants to land and where the most friction lives. The queue restart is real progress, but anyone planning a large load here should price in cost-allocation uncertainty and a capacity market under strain. The co-location rules are the model the rest of the country is watching.

Recent reforms
Source-backed- 2025-12FERC co-location show-cause order
FERC directed PJM to create three new transmission service options for co-located large loads and revise behind-the-meter generation rules to curb cost-shifting.
Source - 2026-02Co-location compliance filings
PJM filed Jan 20 and Feb 23, 2026 compliance proposals establishing a Necessary Studies process requiring co-located generators to bear upgrade costs and adjust Capacity Interconnection Rights.
Source - 2026-06FERC approves Expedited Interconnection Track
FERC approved PJM’s temporary Expedited Interconnection Track for large, shovel-ready capacity resources. PJM expects qualifying projects to execute GIAs within 10 months and be operational within three years.
