This bill changes the rules for keeping power plants running when shutting them down might cause electricity shortages or blackouts. It lets a federal agency called FERC (the Federal Energy Regulatory Commission, which oversees electricity markets and pricing across state lines) order a power plant to stay open for up to five years if closing it would threaten the reliability of the power grid, and it lets more parties—like regional grid operators, not just state utility commissions—raise that concern in the first place. Power plant owners would also need to give five years' notice before retiring a plant, except in emergencies, and customers would end up covering the extra costs through their rates. Notably, any actions a plant takes to comply with one of these keep-open orders would be excused from having to follow federal, state, or local environmental laws.
