The power cut hit the island at 10.26am, EDF announced, blaming the blackout on a “localized incident”.
The electricity giant said some 175,000 homes were left without power.
EDF said “all its teams were mobilized to ensure a return to normal as soon as possible”, but said it was too early to determine what had caused the power cut.
Un incident localisé s’est produit à 10h26, privant la moitié des clients de la Corse d’électricité. Toutes nos équipes mobilisées pour un retour à la normale au plus vite. #ServicePublic
