Beyond Synchronisation: Experience of Litgrid in Protecting Critical Energy Infrastructure

In 2025, the Baltic transmission system operators completed a six-year journey to synchronise their power systems with the Continental European Synchronous Area, supported by major investments in grid infrastructure and control systems. Against a deteriorating regional security environment and the ongoing war in Ukraine, protecting these investments from hybrid threats and sabotage has become an increasingly urgent challenge. In response, Litgrid established its Infrastructure Resilience Programme, which aims to strengthen the physical protection and resilience of critical grid assets by 2029. This presentation will share Litgrid’s experience in establishing and implementing the programme, including key partnerships, early achievements and long-term ambitions. It will also explore how the transmission and distribution industry can contribute to building power grids that are robust, resilient and better protected against emerging security threats
