Visual Primer: PJM’s Price Cap and Floor Proposal for Capacity Auctions Raises Concerns Over Market Distortion

PJM Interconnection LLC, which operates the grid across 13 states and the District of Columbia, has proposed a price cap and floor for its upcoming capacity market auctions for the 2026/2027 and 2027/2028 delivery years.
