 Historique:

Les postes électriques de Sanssac l'Église et de Trevas n'existaient pas lors de la création de la ligne. Elle allait donc jusqu'à la Rivière (Saint-Étienne). La ligne a été fractionnée lors de la création des postes de Sanssac l'Église qui a vu le jour en 2001 et le poste de Trevas créé en 1987. En 1950, le poste de Pratclaux a été créé, c'est à ce moment là qu'elle a été raccourcie. À l'origine, elle allait jusqu'à la centrale hydro-électrique de Monistrol d'Allier.

## Description du tracé:

* La ligne à très haute tension débutait au poste de Sanssac l'Église.
* Elle passait au nord du Puy en Velay sur des hautes collines visible depuis la ville.
* Elle traversait la vallée de la Loire et la D103 et rentrait dans la vallée de la Suissesse en longeant la D7.
* Après être sortie de la vallée, elle pénétrait dans la vallée voisine, celle du Merdant tout en longeant la D7.
* Par la suite, la ligne électrique repassait sur la D103, puis passait à proximité de la zone industrielle de Saint-Maurice de Lignon.
* Ensuite, la ligne passait sur la N88 et passait par dessus la vallée du Lignon.
* Enfin elle se terminait au poste de Trevas.
