The latest PJM Interconnection capacity auction for the 2026–2027 delivery year concluded with a record capacity price of $329.17/MW-day, a 22% increase from 2025 levels. The results reflect ongoing supply constraints and rising electricity demand across PJM’s 13-state footprint, which includes parts of the mid-Atlantic, Midwest, and Washington D.C. 

The PJM capacity auction is a forward market that ensures enough electricity generation is available to meet peak demand. Generators and other capacity providers bid to supply power for the coming year, and winning bids set a price that is partly reflected in consumer and business electricity bills. In short, the auction pays for grid readiness, even before electricity is actually used. 

PJM secured 134,311 MW of unforced capacity for 2026–2027, slightly above the projected reliability requirement. However, the grid remains tight, with peak load forecasted 5,400 MW higher than 2025, largely due to growing data center demand. For the 2027–2028 auction, PJM reported securing 134,479 MW at $333.44/MW-day, leaving the system 6,623 MW short—enough to power roughly 6.6 million homes. 

The Federal Energy Regulatory Commission (FERC) approved a pricing collar of $175–$325/MW-day for the 2026–2027 and 2027–2028 delivery years. PJM adjusted the ceiling slightly based on actual generation performance, including outages, resulting in the final $329.17/MW-day price. 

To improve grid reliability, PJM has added 2,669 MW of new generation, retained 1,100 MW from postponed retirements, and launched long-term infrastructure projects totaling 11,000 MW. Despite these measures, supply remains below demand, and households and businesses in PJM’s territory are expected to face higher electricity costs starting mid-2026. 

State officials have expressed concern over rising costs and grid stability. Governors from Delaware, Illinois, Kentucky, Maryland, Michigan, New Jersey, Pennsylvania, Tennessee, and Virginia have urged PJM to improve transmission planning and capacity integration. Some states are considering legislative measures to review their participation in the PJM market. 

Experts stress the importance of proactive energy strategies for businesses. Recommendations include securing fixed-rate contracts, signing multi-year agreements, improving energy efficiency, and participating in demand response programs to manage the impact of rising capacity charges.
