## Histoire:

Les origines de la ligne remontent à la mise en service en 1924 du barrage de Chancy Pougny à Challex, sur la frontière Franco-Suisse. Son but initial était d'approvisionner en énergie les usines métallurgiques du Creusot et le groupe Schneider & Cie avait pour cela fait construire une ligne double à 120 000 volts de 140 km achevée en 1926. Celle-ci arrivait à Ecuisse au poste de transformation *Jeanne Rose* (appelé aujourd'hui *Henri-Paul*) d'où le courant était ensuite distribué sous la tension de 45 KV.

Mais comme le Creusot ne pouvait absorber toute l'énergie produite par le barrage, il fallait vendre l'excédent dans les départements voisins de la Nièvre et de 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. Le groupe, associé à la Société Anonyme des Mines de Blanzy, fonda ainsi la *Compagnie Bourguignonne de Transport d'Energie* (BTE), destinée à transporter et livrer l'électricité.

Cette ligne électrique est donc construite en 1926, et permettait originellement de relier le poste d'Henri-Paul au poste de Sombernon (permettant l'alimentation de Montbard et de Dijon par l'intermédiaire de deux lignes de 72 KV).

~~***Entre 1949 et 1952, une nouvelle ligne est construite entre Vieilmoulin et la (section à améliorer...).***~~

En 1960, la tension de la ligne a été rabaissée à 63 KV afin d'être raccordée en piquage au nouveau poste d'Épinac et est connectée à la ligne à 72 KV reliant Sombernon à Vieilmoulin (baissant ainsi sa tension). En 1964, elle fut connectée au poste de Crugey et entre 2002 et 2006 au poste d'Aray le Duc (c'est à ce moment là que la section entre la limite de la Saône et Loire et Vic des Prés fut démontée).

La ligne subit une lourde modernisation à la fin de l'année 2019. Cela a conduit au remplacement de tous les anciens pylônes Nappes datant de 1926 par de nouveaux pylônes, d'une adaptation du tracé et du changement des conducteurs.

## Description du tracé:

* La ligne à haute tension débute au poste d'Arnay le Duc qui se situe au sud de la ville, elle passe au-dessus de la D906, puis de la D17 qu'elle va longer jusqu'à Bligny sur Ouche, après être passée en dessous des lignes à 400 KV Henri-Paul-Vieilmoulin et Grosne-Vieilmoulin. Elle se redirigera ensuite vers le nord.
* Au niveau de Crugey, elle se redirige vers le nord-est ou elle se raccorde à la section Crugey-Vieilmoulin jusqu'au poste.
* Après être passée sur le canal de Bourgogne, puis sur l'A6, elle arpente les collines jusqu'à la D905. Elle se dirigera aussitôt vers le nord-ouest jusqu'au poste de Vieilmoulin.
