This bill clarifies and expands the Federal Energy Regulatory Commission's (FERC) jurisdiction over the interconnection of significant electricity consumers to the interstate transmission grid. It specifically grants FERC authority over the interconnection of large load facilities , defined as those with a projected aggregate peak electricity demand of 100 megawatts or greater, to facilities used for the transmission of electric energy in interstate commerce. FERC is also given the power to adjust this 100 MW threshold by rule to ensure bulk-power system reliability and fair transmission service. The legislation mandates that these interconnections are subject to the requirements of the Federal Power Act concerning just and reasonable rates and non-discriminatory service, treating them as a component of open access transmission service . Within 18 months of enactment, FERC must issue a final rule establishing standardized procedures and agreements for these large load interconnections, including for hybrid facilities that combine load and generation at a single point of interconnection. Crucially, the bill explicitly preserves the authority of State and local governments over various aspects of the electric power system. This includes the siting, permitting, or construction of any facility, as well as retail electric service or rates, local distribution facilities, and the generation of electric energy, ensuring a balance between federal oversight and state prerogatives.
