In the Alps, a lightning strike damaged a high-voltage power line that connects France and Switzerland, forcing technicians to repair the line at an altitude of 2,000 meters. The damaged section is located on the cliffs of Sixt-Fer-à-Cheval in the Haute-Savoie region. Because there is no ground access to the site, workers used baskets suspended from helicopters to transport equipment to the top of a 40-meter-high tower. During the repair, electricity was temporarily cut off, but there were no major disruptions to the power network. The technicians, known as line workers, had to carefully repair the damage caused by the lightning strike. According to Patrick Dumoulin, a project manager at RTE, the lightning hit about 600 meters from the tower. It broke part of the metal strands that carry electricity, weakening the structure. To fix the damage, the workers first applied tape to the cable and then wrapped new, stronger metal strands around it to reinforce the line. This repair is part of a larger effort to make the electrical network more resilient to extreme weather conditions caused by climate change. Over the past 15 years, more than 24 billion euros has been invested in strengthening the network to withstand rising temperatures expected by 2040 and 2050. François Constensous, director of the maintenance group RTE Savoie and Haute-Savoie, said the company is continuing to develop new materials and technologies to improve the network's ability to handle harsh conditions. Extreme heat waves have also added to the cost of adapting electrical infrastructure, with an additional 1.7 billion euros spent on upgrades. According to an RTE line worker, operations like this are essential to prevent short circuits and power outages, ensuring the stability of the electrical grid in the face of increasing environmental challenges.
