As of October 6, 2026, Monongahela Power (Mon Power), a FirstEnergy subsidiary, filed a complaint with the Federal Energy Regulatory Commission (FERC) seeking to recover $145 million in costs incurred during Winter Storm Fern in January and February. [1] The utility alleges that PJM's advance scheduling of gas-fired generators, intended to secure fuel and ensure sufficient generation during the storm, may have violated market rules and contributed to higher costs for Mon Power. [2] The utility said its lower-cost coal-fired plants were repeatedly dispatched at minimum output levels while more expensive gas generation was scheduled in advance. PJM has urged FERC to dismiss the complaint, arguing that downed transmission lines on Mon Power's system were the primary cause of the price differences. Independent power producers also oppose the requested retroactive market adjustments, warning that reopening settled market outcomes could undermine investment certainty and discourage generators from taking steps to maintain reliability during future emergencies. The dispute raises broader questions about how grid operators balance emergency reliability measures with market efficiency and cost allocation during extreme weather.
