siirtokatkojen

Siirtokatkojen is a Finnish term referring to a planned, temporary interruption of electricity supply. These outages are typically implemented by electricity distribution companies to manage demand during periods of exceptionally high consumption or to perform essential maintenance and repair work on the grid. The goal is to prevent a widespread, uncontrolled blackout by selectively disconnecting power to certain areas.

The implementation of siirtokatkojen usually involves a predetermined rotation of affected regions, with consumers often notified in advance through various channels, including company websites, SMS messages, or local media. The duration of a siirtokatko is generally limited, aiming to restore power as quickly as possible once the critical load or maintenance task is completed. This measure is a critical tool in maintaining the stability and reliability of the electricity network, especially in regions with a significant reliance on hydropower or other weather-dependent energy sources, or during extreme weather events that strain the grid. While inconvenient for those affected, siirtokatkojen are designed to protect the integrity of the entire power system.
