 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 2 fois lors de la création des postes de Sanssac l'Église qui a vu le jour en 2001 et 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:

* C'est sur un plateau que la ligne débutait au poste de Trevas.
* Elle vallonnait les collines de la Haute-Loire en direction de La Séauve sur Semène et de Saint Didier en Velay, qu'elle traversait littéralement.
* Après Saint Just Malmont, elle traversait un grand vallon, celui du ruisseau d'Échapre, et plus loin, elle passait dans le département de la Loire.
* Enfin, après quelques kilomètres parcourues dans ce département, elle descendait une colline et se terminait au poste de la Rivière à Saint Étienne.
