Reliability in the West: Inverter-based Resources - IBR Registration

The increasing integration of IBRs has led to a reliability gap where many IBR owners and operators connected to the Bulk Power System are not registered with NERC or complying with its Reliability Standards. In response, FERC issued an order in 2022 directing NERC to identify and register these unidentified IBRs. In March 2024, NERC filed proposed revisions with FERC that would lower the registration threshold for these resources. This discussion will highlight and review the effects of the proposed threshold changes.
