ENTSO-E has published the third Probabilistic Risk Assessment Report (PRA), a report that comes out every other year, detailing Europe’s latest progress on integrating probabilistic methods into power system security.
The report shows advances in data collection, impact assessment, and probability-computation testing — strengthening the complementary approach to the established “N-1” security principle.
This work is developed jointly by all TSOs under the Methodology for coordinating operational security analysis (CSAM) framework and reflects growing momentum toward more robust, risk-aware system operation.
