E.DSO Position Paper: Climate Resilience Metrics for Electricity Grids

The E.DSO Climate Risks and Adaptation Working group, as part of E.DSO Policy and Regulation Committee, has been working on a Position Paper on climate resilience metrics in terms of electricity grids.

Different metrics are required to quantify the reliability of a network to ensure interventions and improve its performance. Traditionally, metrics such as CML (SAIDI) or CI (SAIFI) have worked well. However, the environment for electrical utilities is ever changing, assets are aging, network usage is changing to address climate change, and climate change is increasing the frequency and magnitude of once considered high impact low frequency (HILF) events.

This paper explores reliability and resilience and how resilience metrics can provide the basis to measure networks improvements in a changing climate environment.
