On November 17th, the Federal Energy Regulatory Commission (FERC) took a number of actions that focused on inverter-based resources (IBRs). The measures included orders proposing that new technologies and standards be created to improve and protect the reliability of the bulk power system and strengthen grid reliability, the Commission’s main endeavors.
IBRs are solar photovoltaic, wind, fuel cell and battery storage resources that use power electronic devices to change direct current power, produced by generators, into alternating current power that is then transmitted on the bulk-power system.
FERC’s orders include the following three IBR-focused measures:
an order directing the North American Electric Reliability Corporation (NERC) to develop a plan to register the entities that own and operate IBRs (RD22-4)
a notice of Proposed Rulemaking to direct NERC to develop reliability standards for IBRs that cover data sharing, model validation, planning and operational studies, and performance requirements (RM22-12)
an order approving reliability standards that are related to IBRs, which NERC proposed earlier in 2022 (RD22-5)
