On 21 June 2024 around 12:20, a major grid incident occurred in the South-Eastern part of the Continental Europe power system. The incident resulted in a black-out in the electricity grids of Albania, Montenegro, Bosnia-Herzegovina and a partial blackout in Croatia. The affected TSOs, with the support of the neighbouring TSOs, restored the power on their grids within approximately 2 hours aiming at minimizing the impact of the disruption on the consumers.
