## Historique :

Les origines du barrage de Chancy-Pougny remontent à 1913 et à la convention passée par les états Français et Suisse pour l'exploitation de la force hydraulique du Rhône. L'ouvrage, situé à Challex près de la frontière, fût mis en service en 1924 et son objectif initial était d'approvisionner les usines métallurgiques du Creusot. Dans cette optique, le groupe Schneider&Cie dirigea la construction d'une ligne double à 120 000 volts sur 140 km qui sera achevée en 1926.

Mais comme le Creusot ne pouvait absorber toute l'énergie produite par le barrage, il fallait vendre l'excédent dans la Nièvre et la Côte d'Or. La famille Schneider étendit donc son programme de transport de force avec deux autres lignes à 120 KV dirigées vers Sombernon au Nord et Garchizy près de Nevers à l'Ouest (via Gueugnon et Champvert). Ainsi, le poste de transformation 120/45KV *Jeanne Rose* (aujourd'hui *Henri Paul*) fut mis en service pour devenir le centre nerveux de ce réseau d'interconnexion. Le groupe fonda également la *Compagnie Bourguignonne de Transport d'Energie* (BTE), destinée à transporter et livrer le surplus d'électricité produit par l'usine de Chancy-Pougny.

Cette ligne joua donc un rôle essentiel au sein du réseau de la BTE. Elle assurait l'apport en énergie du Creusot mais aussi de villes comme Bourges, Nevers ou Dijon.

La construction du barrage de Cize-Bolozon sur son parcours entraîne un fractionnement de la ligne dès 1928. Les deux tronçons créés depuis le poste de Cize vont connaitre alors des fortunes diverses :

* La ligne Cize - Henri-Paul sera exploitée jusqu'aux années 1990 avant d'être progressivement démontée dans sa majeure partie.
* La ligne Cize - Pougny devient déjà obsolète à la fin des années 1940 avec la mise en service du barrage de Génissiat. En effet, dans la forêt de Montréal, la ligne est déroutée en 1949 vers ce qui est alors l'usine hydro-électrique la plus puissante d'Europe. La section de Montréal à Pougny est mise hors tension puis démontée au cours des années 1950.

## La ligne de nos jours :

Sur les 140 km de ligne construite à l'époque, il n'en reste aujourd'hui que 24. Seules deux sections de 9 et 15 km sont encore exploitées par le réseau à 63 KV, mais sur un seul circuit.

## Description du tracé :

* La ligne partait du poste *Henri-Paul* et passait au dessus de la LGV Sud-Est. Elle suivait une direction du Nord-Ouest/sud-Est et son tracé était plus ou moins rectiligne jusqu'à Tournus. Entre temps, elle franchissait la Grosne et traversait le bois du *Grand-Bagny*.
* Elle contournait Tournus par le Sud, franchissait la Saône puis bifurquait un peu plus vers le Sud à Lacrost avant d'entrer dans l'Ain.
* Dans l'Ain, elle croisait l'A39 à 1 km au sud de l'*aire de Bény,* traversait la forêt de *Chareyziat* puis la voie ferrée de Mouchard à Bourg-en-Bresse au sud de Saint-Etienne-du-Bois.
* La ligne attaquait ensuite les contrefort du Jura. Elle traversait d'abord la *forêt de la Rousse*, croisait la voie ferrée Bourg-Bellegarde, descendait dans les gorges de l'Ain au niveau de Cize puis remontait sur l'autre versant.
* Elle longeait ensuite la voie ferrée de Nurieux à La Cluse avant de bifurquer franchement vers l'Est et de monter dans la forêt de Montréal.
* Elle tournait vers le Nord-Est après la D74 puis passait sur les communes de Charix et de Plagne. Au croisement avec la ligne 225KV Champagnole-Génissiat, elle bifurquait à nouveau vers le Sud-Est.
* Elle traversait le village de Champfromier, franchissait les gorges de la Valserine puis passait au Nord de Menthières.
* Elle montait ensuite à 1300m d'altitude près du *col du Sac* puis descendait dans le pays de Gex en se dirigeant vers Logras, au Nord de Farges. Pour finir, elle traversait le *bois de Ban* avant d'entrer dans le poste de Pougny.

## Tronçons récupérés pour la création de nouvelles lignes :

* Ligne 150 KV - (Cize - Henri-Paul)
* Ligne 120 KV - (Cize-Pougny)
* Ligne 150 KV - (Cize-Génissiat)
* Ligne 63 KV - (Romenay - Croix-Leonard)
* Ligne 63 KV - (Brou - La Cluse)

## Note :

Preuve de son caractère stratégique pour le groupe Schneider&Cie; un relais téléphonique fut installé au *col du Sac* dans le Jura et servait à surveiller la ligne en hiver, pour éviter des surcharges de neige. La ligne électrique était couplée à une ligne de téléphone entre Farges et Menthières pour appeler des renforts dans les deux villages quand la situation l'exigeait. L’usine de Chancy-Pougny était alors alertée et coupait le courant pour que l'équipe d'entretien des lignes puisse graisser les câbles.
