PJM Files to Extend $325/MW-Day Capacity Price Cap Through 2030
On March 2, 2026, PJM Interconnection filed proposals at FERC to extend the existing capacity price collar through the 2029/2030 delivery year. The collar caps auction clearing prices at approximately $325/MW-day and sets a floor at $175/MW-day. PJM estimates this mechanism will save customers $27 billion compared to an uncapped scenario. Additionally, PJM proposed an expedited interconnection track to accelerate new generation coming online and a reliability backstop procurement mechanism targeted for September 2026.
What PJM Filed
On March 2, 2026, PJM Interconnection filed two critical proposals at the Federal Energy Regulatory Commission:
- Price Collar Extension: Extending the capacity price ceiling of approximately $325/MW-day and floor of approximately $175/MW-day through the 2028/2029 and 2029/2030 delivery year auctions. Without this cap, the 2026/2027 auction would have cleared at approximately $389/MW-day.
- Expedited Interconnection Track: A fast-track process to accelerate integration of new large-scale generation projects, specifically targeting the supply-demand gap driven by data center growth.
Why This Matters for Commercial Buyers
The price collar is the single most impactful regulatory mechanism protecting commercial electricity rates in PJM territory. Without it, the tight supply-demand balance driven by 5,400 MW of data center demand and ongoing generation retirements would push capacity costs significantly higher.
Budget Impact
The $27 billion savings projection means commercial facilities in PJM states avoid approximately $0.005-0.01/kWh in additional capacity charges through 2030. For a facility using 10,000 MWh/year, this represents $50,000-$100,000 in avoided costs.
The Reliability Backstop
PJM also announced development of a "reliability backstop procurement" mechanism, targeted for September 2026. This would give PJM the authority to directly procure generation resources if the market fails to deliver sufficient supply — a safety net that effectively acknowledges the capacity price collar may not provide enough incentive for new generation investment.
The next capacity auction is scheduled for June 30, 2026, covering the 2028/2029 delivery year. This will be the first auction under the extended price collar if FERC approves the filing.
Procurement Strategy
For energy managers negotiating contracts in PJM territory:
- Budget certainty improved: The price collar provides a known ceiling for capacity costs through 2030, reducing long-term budget uncertainty.
- Lock-in timing: Consider multi-year fixed-rate contracts that span the 2028-2030 period while the collar is in effect.
- Demand Response value stable: DR revenue remains attractive at $325/MW-day — a facility that can curtail 1 MW earns approximately $100,000/year.
