## Historique:

#### *Exploitation à 120 puis 150 KV :*

Afin d'exploiter la force hydraulique de l'Ance et de l'Allier, La Compagnie Électrique de la Loire et du Centre fît construire une centrale à Monistrol en 1926 sur la rive gauche de l'Allier, en même temps que la mise en eau du barrage de Pouzas.

Par le biais de la STEC, *Société de Transport d'Energie du Centre* qu'elle fonda en 1921, la CELC réalisa en parallèle cette ligne à haute tension pour renforcer l'alimentation du bassin industriel et minier de la région Stéphanoise (déjà alimentée depuis 1922 par les deux ligne à 120 KV Beaumont-Monteux-La Rivière). Celle-ci évacuait l'énergie depuis le poste élévateur installé à côté de l'usine.

*Arrivée de la ligne à Monistrol, années 1930 (Image Delcampe.net)*

Initialement exploitée en 120 KV, elle est la première ligne à ce niveau de tension construite en Auvergne. A l'instar des autres lignes de transport gérées par la STEC, sa tension fut relevée à 150 000 volts en 1932. Le développement du réseau haute tension entraina la création d'un deuxième poste électrique à Monistrol de l'autre côté de l'Allier, à 150m du premier. Le tracé de la ligne s'en trouva légèrement modifié; un portique à deux nivaux fut installé à côté de la centrale pour la raccorder à ce nouveau poste.

   Un piquage fut créé sur la ligne en 1950 au Chambon-Feugerolles pour y raccorder la centrale thermique du Bec qui entrait en service à ce moment-là. En 1961, elle est fracturé au niveau de ce piquage suite à la suppression de l'échelon 150 KV dans le poste de *La Rivière.* Il en résulte la création des lignes 63 KV Le Bec - La Rivière et 150 KV Monistrol - Le Bec. Cette dernière reste cependant connectée au réseau 150 000 volt de la région grâce à la ligne Le Bec - Le Soleil mise en service quelques années plus tôt.

#### *Déclassement et dépose partielle :*

L'année 1978 est le théâtre d'une profonde réorganisation du réseau à Monistrol. L'imposant poste électrique de 1926 est remplacé par un poste 63 KV plus petit tandis que l'échelon 150 KV disparait de celui installé en rive droite dans les années 1930 (Ce dernier sera démantelé entre 1980 et 1983). La ligne est alors raccordée au poste de Pratclaux et exploitée désormais en 63 KV.

Peu de temps après (entre 1980 et 1982), un tronçon de 3 km est déposé au Chambon-Feugerolles et la ligne 63 KV venant de *la Rivière* est déroutée vers Firminy.

En 1987, Un tronçon central de 42 km est démonté suite à la création du poste 225 KV de Trévas. Les 2 extrémités sont réutilisées pour créer les lignes Trevas-Le Bec et Pratclaux-Le Puy .

En 2001, une section de 3 km est supprimée entre la D111 et Vals près le Puy après la mise en service du poste de Sanssac.

## Description du tracé:

* La ligne partait de l'usine électrique de Monistrol d'Allier et montait brusquement au dessus de la vallée.
* Depuis Pratclaux, elle prenait une trajectoire rectiligne sur les plateaux en direction du Puy, passant au Sud de Bains et longeant la D589 sur 2km.
* Elle contournait le Puy en Velay par le Sud, franchissait la Loire au Nord de Coubon et passait sous le Mont St Maurice, se dirigeant toujours vers l'est.
* Elle croisait ensuite la D15 une première fois puis bifurquait vers Saint-Julien-Chapteuil juste avant de la croiser de nouveau.
* Arrivée 1 km à l'ouest de Saint Julien Chapteuil, elle partait vers le Nord jusqu'à Malataverne, croisant la N88 après Le Perthuis.
* Elle tournait ensuite vers le nord-est, passait au dessus de Saint Maurice du Lignon, franchissait les gorges du Lignon et croisait plusieurs fois la N88 avant d'atteindre Firminy.
* Avant Firminy, elle tournait vers l'est et longeait la banlieue Stéphanoise par le sud avant d'entrer dans le poste de La Rivière.

## Notes:

La forme des pylônes est plutôt atypique. Cette architecture était beaucoup utilisée dans l'entre-deux guerre par la STEC pour le réseau 120 000 et 150 000 volts; c'est pour quoi les lignes de ce type encore visible aujourd'hui sont concentrés en Auvergne-Rhône-Alpes, à quelques exceptions près...
