The "Reliable Grid Act" seeks to bolster the reliability of the nation's electric grid by imposing restrictions on the Environmental Protection Agency's (EPA) regulatory actions. Specifically, it prohibits the EPA Administrator from enforcing any rule or regulation that limits the continuous, previously permitted operation of any dispatchable electric generating unit . This prohibition is set to remain in effect until the North American Electric Reliability Corporation (NERC) officially categorizes all areas served by the bulk-power system as presenting a "normal risk," as determined by its 2023 Long-Term Reliability Assessment. The bill defines a dispatchable electric generating unit broadly, including steam generating units, integrated gasification combined cycle units, and stationary combustion turbines, or other units capable of adjusting their electricity generation on demand. A Sense of Congress section emphasizes that reliable and affordable electricity is a fundamental necessity, urging the Administrator to prioritize grid reliability and avoid regulations that could lead to the premature retirement of essential power units. It criticizes past EPA regulations for allegedly forcing the early retirement of reliable capacity, such as coal and natural gas units, which has contributed to increased electricity shortages and challenges to grid stability. The legislation specifically cites regulations like the "New Source Performance Standards for Greenhouse Gas Emissions" as examples of rules that have exacerbated capacity inadequacies. It argues that jeopardizing grid reliability directly endangers human health and life, thereby contradicting the EPA's core mission. The bill further calls for the Administrator to identify power units at risk of premature retirement and to provide waivers, while also advocating for a halt to the implementation of certain electric power sector rules issued under former Administrator Regan.
