Purpose of the NERC Level 3 Alert

The NERC Level 3 Alert aims to address systemic modeling and performance failures in inverter-based resources (IBRs). These issues have led to over 15,000 MW in generation losses across multiple grid disturbances since 2016. Generator Owners (GOs) must act urgently to validate IBR performance and ensure accurate power system modeling.

Key NERC Compliance Responsibilities for IBR Generator Owners

1. Model Accuracy and Verification

  • Obtain validated EMT (Electromagnetic Transient) and PSPD (Positive Sequence Phasor Domain) model reports from OEMs.
  • Benchmark EMT models against measured performance; explain any discrepancies.
  • Confirm all model parameters match as-built equipment and settings for NERC compliance.

2. Performance Validation of IBR Systems

  • Conduct conformity tests to verify real-world behavior of installed equipment.
  • Use staged commissioning tests for frequency response—not just live event data.
  • Validate controls for accurate IBR grid response modeling.

3. Change Management Compliance

Implement a documented process for tracking:

  • Control parameter changes
  • Firmware upgrades
  • Equipment setting modifications
    Notify Transmission Planners (TPs) and Planning Coordinators (PCs) of any model-impacting updates.

4. Information Management for Compliance Audits

Maintain a current internal database detailing:

  • Inverter/controller make, model, and firmware version
  • Active/reactive power specs
  • Ride-through, protection settings, and voltage/frequency control strategies

5. Design Stability and IBR Modeling

  • Use publicly available interconnection requirements to minimize later model revisions.
  • Engage OEMs early to secure modeling deliverables in purchase agreements.
  • Prioritize stability and reproducibility in power system design.

Ensure your IBR systems meet NERC standards with our comprehensive compliance services.

NERC Reporting Deadlines for Generator Owners

  • Acknowledge Alert: by May 27, 2025
  • Submit Compliance Report: by August 18, 2025
    Use the NERC Alert System for submission and approval.

Recommended Power System Software for IBR Compliance

Software Tool Purpose Required Expertise
PSSE + TSAT Positive sequence dynamics and stability modeling PSPD tuning and response validation
PSCAD/EMTDC EMT inverter simulation Transient analysis and EMT model validation
DigSILENT PowerFactory Grid-wide dynamic studies Frequency and voltage control modeling
MATLAB/Simulink Custom control modeling EMT modeling and signal processing
HYPERSIM/RTDS Real-time hardware-in-the-loop testing Real-time EMT validation and HIL testing

Proficiency in power system model validation and field data benchmarking is critical for NERC IBR compliance.

Regulatory and Grid Reliability Emphasis

While this NERC Level 3 Alert is not punitive, non-compliance may highlight systemic reliability risks and result in future regulatory scrutiny. Accurate IBR modeling and system responsiveness are essential for bulk power system (BPS) reliability.
