Incident on the 400,000 volt power transmission line linking Marseilles and Nice

At 9.40 this morning, a major incident occurred on RTE's extra high voltage power line (400,000 volts) linking the cities of Marseilles and Nice. The disturbance was caused by violent thunderstorms in the region, which resulted in the power line being disconnected.

It led to an outage of approximately 1,500 MW, affecting some 1.5 million customers in the Var and Alpes Maritimes départements of south-eastern France.

Power was gradually restored to all customers of RTE's transmission network and the distribution grid run by ERDF during the course of the morning, thanks to joint efforts by staff from the two companies. The power supply was fully restored at 1.10pm.

The extra high voltage power grid is mainly supplied by one 400,000 volt dual circuit line in the Var and Alpes Maritimes areas, and as a result is structurally weak.
