The utility attributes the incident to thunderstorms and strong winds, which it says simultaneously damaged four 225 kV lines supplying the Ouled Haddou and Dar Bouazza substations. Its statement, reported on 12 November, says partial restoration began at 6:23 p.m.
The announcement follows earlier reports of a gradual recovery. It concerns electricity supply to the substations and does not establish the full extent of damage caused by the storm.
