Ligne 70 KV - (Coudes-Liève)

## Présentation :

La ligne Coudes-Liève est une ancienne liaison à 70 000 volts qui reliait la centrale électrique de Coudes au poste de Liève à Clermont-Ferrand. Elle fut déclassée en ligne 20 KV à la fin des années 1950 puis démantelée progressivement durant la seconde moitié du 20e siècle. Il n'y a plus aucune trace de cette ligne dans le paysage aujourd'hui.

## Historique :

Cette ligne à double circuit fut construite au début des années 1920 par la *Compagnie Hydro-électrique d'Auvergne* (CHEA). La société exploitait à l'époque plusieurs centrales hydrauliques (notamment sur la Sioule) et des usines thermiques dont celle de Coudes. Cette dernière possédait une puissance de 25,5 mégawatts et l'énergie était évacuée par deux lignes 70 KV à doubles ternes dirigées vers Brioude et Clermont-Ferrand ainsi que deux lignes simples à 25KV, Elle fut probablement mise en service en même temps que les lignes. Les circuits 70 et 25KV étaient installés conjointement sur deux portiques pour franchir l'Allier à la sortie de l'usine *(voir image ci-dessous)*.

En outre, la CHEA développa un réseau de transport et de distribution d'énergie qui à terme allait couvrir tout le Puy-de-Dôme et une partie des départements limitrophes (Allier au Nord, Cantal et Haute-Loire au Sud).

En 1927, le circuit Ouest de la ligne fut sectionné au niveau du croisement des routes D2009 et D771 pour être dérouté vers le poste électrique d'Enval. En 1946, la ligne passa sous le giron d'EDF suite à la nationalisation de l'ensemble du réseau à haute tension.

A la fin des années 1950, EDF opéra des modifications importantes sur le réseau électrique autour de Clermont-Ferrand. Un poste 225/63KV fut créé à Malintrat en 1959 et le réseau à 63 000 volts actuel commença à se développer. Par ailleurs, la centrale de Coudes avait cessé son activité au cours de cette décennie et la ligne Coudes-Liève n'avait plus de raison d'être. Elle fut donc déclassée et intégrer au réseau de distribution à 20KV. Par la suite, elle fut déposée progressivement à partir des années 1960 jusqu'à disparaître totalement au début des années 2000.

### *Chronologie de la dépose de la ligne :*

* 1959 : Suppression du tronçon Liève - la Sarre suite à la création d'une ligne 63KV La Sarre-Malintrat. Le reste de ligne est déclassé en 20KV et raccordée au poste de la Sarre.
* 1968-1972 : Dépose d'un tronçon de 2,5 kilomètres entre La Sarre et le concessionnaire Mercedes actuel d'Aubière. Une autre section de 5 km est démontée à la même période entre Perignat-les-Sarlièves et le poste électrique situé au croisement des routes D52 et D978 à Orcet.
* 1974-1977 : Lors des travaux de déviation de la RN9 au niveau de Coudes et Pérignat-les-Sarlièves, deux autres sections de ligne sont supprimées ; entre la centrale de Coudes et l'échangeur N°7 de l'A75 ainsi qu'entre Aubière et l'actuel rond-point de la RN89 et de l'échangeur N°2.
* 1978-1983 : Un court tronçon est déposé aux Martres-de-Veyre à cause du développement urbain de la commune.
* 1989-1991 : Un tronçon de d'un km est démonté entre les Martres-de-Veyre et Orcet (au croisement des routes D52 et D978).
* 1994-1996 : Dépose de la ligne entre Pérignat et le rond point de l'échangeur N°2 de l'A75 au Sud d'Aubière.
* 1996-1999 : Dépose de la section entre l'échangeur N°7 de l'A75 et le croisement des routes D96 et D630.
* 2000-2004 : Suppression du dernier tronçon restant entre le croisement des routes D96 et D630 et les Martres-de-Veyre.

## Description du tracé :

La ligne suivait globalement une direction Nord-Sud et une bonne partie de son tracé longeait l'ancienne RN9 :

* A la sortie de la centrale thermique de Coudes, la ligne franchissait l'Allier à l'aide de deux portiques supportant également la ligne Coudes-Brioude.
* Elle tournait ensuite vers le Nord, traversait la D797 (ex RN9) puis longeait la route par l'Ouest jusqu'à hauteur de Montpeyroux.
* Elle croisait ensuite une seconde fois la RN9 et longeait cette fois la route côté Est jusqu'à la sortie Nord d'Authezat.
* Après Authezat, elle partait en direction du Nord-Est pour se dirigeait vers Longues en suivant la D96 puis la D630. A Longues, elle franchissait deux fois l'Allier pour longer les bâtiments de la papèterie de la Banque de France.
* Elle suivait ensuite la D625 puis traversait les Martres-de-Veyres. Elle rejoignait la RN9 sur les hauteurs du village.
* La ligne longeait ensuite la nationale jusqu'à Clermont-Ferrand, traversant notamment Pérignat-les-Sarlièves puis Aubière.
* Après avoir croisé les voies ferrées Paris-Clermont et Clermont-Saint-Etienne, elle laissait la RN9 pour s'engouffrer dans la ville.
* Elle longeait successivement la *rue des Chandiots*, la *rue du Ressort* puis la *rue Pelissier* avant d'entrer dans le poste électrique de Liève.

## Tronçons récupérés pour la création de nouvelles lignes :

* Ligne 70 KV - (Enval-Liève) : déroutage du circuit Ouest au niveau de la Sarre.
* Ligne 70 KV - (Enval-Coudes) : déroutage du circuit Ouest au niveau de la Sarre.

## Notes :

* Comme on peut l'apercevoir sur la photo principale, les pylônes transportaient également un circuit 25 KV sur l'étage inférieur pour assurer la distribution du courant aux communes situées sur le parcours de la ligne.
* Le bâtiment de l'ancienne centrale de Coudes est toujours debout aujourd'hui, il est utilisée par CGP Flexible, un fabriquant de films et emballages industriels.
