ATLANTA – Over the past six years, system events have demonstrated that inverter-based resources (IBR) are having a major impact on generation, transmission and distribution systems. These resources play a critical role in the transition to a more resilient and sustainable future energy landscape, but their unique characteristics present new challenges for grid reliability and stability. As part of its IBR Strategy, NERC is dedicated to identifying and addressing challenges associated with IBRs, sharing risk mitigation techniques with industry and providing best practices and education.
The IBR Registration Initiative is one way NERC addresses these challenges. This initiative, directed by the Federal Energy Regulatory Commission (FERC) in 2022 and launched in 2023, seeks to identify and register owners and operators of currently unregistered bulk power system-connected IBRs, thereby closing the reliability gap in which 16% of IBR owners and operators that are connected to the bulk power system are not yet required to register with NERC or adhere to its Reliability Standards.
NERC recognizes the critical importance of ensuring that identified entities are integrated smoothly and are educated on the scope and role of the ERO Enterprise. To that end, NERC has developed resources to provide support and education on IBRs, the IBR Registration Initiative and the ERO Enterprise model.
