Mercredi 8 mars 2018, Réseau de transport d’électricité a inauguré la nouvelle ligne de 225 000 volts qui traverse la Haute-Loire, de Saint-Privat-d’Allier à Saint-Étienne, et procédé au démontage du dernier pylône de l’ancienne ligne, datant de 1941.
L’axe entre Le Puy-en-Velay, l’Yssingelais et Saint-Étienne concentre d’importants pôles urbains et industriels de la Haute-Loire et de la Loire.
Sur le plan électrique, il était principalement alimenté par une ligne à 225 000 volts.
Construite en 1941, cette ligne avait atteint ses limites techniques. Pour accompagner les évolutions en cours et anticiper le développement futur du territoire, le réseau électrique devait être renforcé.
L’objectif était de remplacer la ligne existante par une nouvelle ligne de plus grande capacité :
87 km de ligne construits dont 7 km en souterrain, 8 000 tonnes d’acier, 619 km de câbles déroulés, 23 communes traversées, un projet à 132,5 millions d’euros, 3 ans de travaux, répartis en trois tronçons. Depuis le 1er décembre, la nouvelle ligne très haute tension, soit 225 000 volts, a remplacé l’ancienne ligne qui datait de 1941.
Vous pouvez retrouver ci-dessous les travaux effectués sur la ligne de St Maurice
