Overview

• Interventions reduced peak outages from about 8,000 customers at 8 a.m. to around 6,000 by midday on July 2
• Over several consecutive days with no nighttime cooling, ground temperatures on paved surfaces rose by dozens of degrees, imposing extreme thermal stress on buried cables
• Incidents were recorded in Occitanie, Provence-Alpes-Côte d’Azur, Île-de-France, Auvergne-Rhône-Alpes and Centre-Val-de-Loire, including two breakdowns in Tours
• Temperature-sensitive junction boxes linking underground cables failed due to heat-driven terrain movements and overheating
• Enedis says the situation remains evolving and that crews are working round the clock to restore service as quickly as possible
