## Historique:

Cette ligne faisait partie de la grande continuité reliant Portet sur Garonne à Saint Victor en 150 KV construite en 1927. Celle-ci fut réalisée par la compagnie du Midi afin de transporter vers la région Toulousaine et les Pyrénées l’énergie produite par la centrale hydraulique du Pinet, construite sur le Tarn entre 1926 et 1929.

Une partie de cet axe à 150 KV a entièrement été supprimé de Lintin à Réquista entre 1980 et 1983 suite notamment au développement du réseau 225 KV dans la région. Le poste source 63KV de Réquista fut mis en service à la même époque, créant ainsi la ligne Réquista – Saint-Victor.

Motivé entre autres par le vieillissement de cette ligne quasi centenaire, RTE projette dans les années 2010 de renforcer le réseau électrique du secteur en créant un échelon 225KV dans le poste de Réquista, raccordé en piquage sur la ligne Pelissier – Saint-Victor. Les installations sont mise en service durant l’été 2021. La ligne Requista – Saint-Victor, devenue obsolète, devait initialement être démontée fin 2021. Elle le sera courant 2022 dans le cadre du projet de raccordement des réseaux 400KV et 225KV sur la commune de Saint-Victor-et-Melvieu.

## Description du tracé:

* La ligne débute au poste de Réquista et se poursuit en direction du nord-est.
* Au niveau de Lestrade et Thouels, la ligne bifurque vers l'est et passe sur le Tarn.
* Elle arrive sur un des plateaux de Saint Victor et Melvieu ou se trouve le poste électrique et s'arrête.
