ATLANTA – In response to FERC Order No. 901 and consistent with NERC’s commitment to identifying and addressing challenges associated with inverter-based resources (IBRs), NERC is actively developing key Reliability Standards projects to enhance IBR planning and ensure reliable grid reliability. NERC’s Order No. 901 work plan includes four milestones designed to meet FERC’s directives within the specified timeframes. Milestone 3 focuses on developing and filing standards that enhance data sharing and model validation for all IBRs. This milestone has a filing deadline of November 4, 2025, with a full implementation target of January 1, 2030.
NERC’s Milestone 3 Summary provides a high-level overview of its associated projects—Project 2020-06 – Verifications of Models and Data for Generators, Project 2021-01 – System Model Validation with IBRs, Project 2022-02 – Uniform Framework Model Framework for IBR, and Project 2022-04 – Electromagnetic Transient Modeling.
Key Milestone 3 Takeaways and Engagement Opportunities
NERC’s assessments indicate a need for additional model types to be used for local reliability studies, particularly throughout the interconnection process and ongoing performance validation. The projects under Milestone 3 specifically address the issues surrounding current model quality.
- Industry Engagement: Stakeholders are encouraged to engage with the drafting teams in early 2025 to facilitate a timely November 2025 filing.
- Comprehensive Approach: While not all projects directly address Order No. 901 directives, they are essential for creating a cohesive strategy for modeling validation and data sharing within NERC’s Reliability Standards.
- Collaborative Updates: NERC’s drafting teams will continue to collaborate and provide regular updates.
