Information on the actual values of the average duration of long interruptions in the system (SAIDI), which occurred due to the fault of companies or due to planned interruptions, is structured by electricity distribution licensees. The data are calculated as the ratio of the total duration of outages per year to the total number of customers.
Data for 2021-2025 were obtained in response to an information request.
Access to SAIDI indicators for 2025 related to force majeure circumstances and actions of third parties is restricted for national security reasons.
