Operational Application of Inertia Measurement Techniques
Project summary
Building on the Inertia Measurement Method Optimisation project (NIA2_NGESO023) which concluded in September 2024 and focused on developing a methodology to validate the accuracy of inertia measurements, this next phase will establish a methodology to incorporate the real-time measured inertia into operational techniques.

Building on the Inertia Measurement Method Optimisation project (NIA2_NGESO023) which concluded in September 2024 and focused on developing a methodology to validate the accuracy of inertia measurements, this next phase will establish a methodology to incorporate the real-time measured inertia into operational techniques.
The phase will also continue analysis to include data that was not available during the original project timeline, enabling continued assessment of the accuracy of real-time commercial systems.
Benefits
This project enhances system resilience and operational decision-making by developing an improved, independent methodology for verifying ‘Rate of Change of Frequency’ RoCoF-based inertia values. It increases confidence in real-time inertia measurements, enabling operators to respond more effectively under changing system conditions. By identifying implausible measurements and supporting post-event analysis at any PMU location, the project strengthens validation of commercial tools and supports more robust system behaviour assessment.
