# Joule substation: SF₆-free 24 kV switchgear retrofit

SIE SA is tendering the complete renewal of the 6.4 kV medium-voltage installation at the Joule substation in Ecublens, including supply and installation of 32 new SF₆-free 24 kV cells. The works cover removal of existing equipment, auxiliary AC/DC systems and batteries, control/protection/communications, civil work, transport, installation, factory and site tests, commissioning and as-built documentation. The installation must first operate at 6.4 kV and later at 21 kV. Civil work and cable adaptations are listed as options. Offers are due 22 December 2026 at 11:30 CET.

    "text": "RETROFIT DES CELLULES 6.4 kV DE JOULE PAR DE NOUVELLES CELLULES 24 KV SANS SF6\nLe présent appel d'offres porte sur le renouvellement complet de l’installation moyenne tension (6,4 kV) du poste de Joule, situé au chemin du Bochet 5 ,1024 Ecublens et la fourniture de 32 nouvelles cellules MT conçues selon une technologie sans SF₆. Le projet s'inscrit dans la stratégie de modernisation du réseau de distribution de SIE SA et constitue une étape majeure de la migration progressive du réseau de distribution de 6,4 kV vers 21 kV. Le projet comprend notamment : * Le démontage, le recyclage et l'évacuation des cellules et matériel MT existantes ; * La démolition et l’évacuation des niches existantes ; * L’évacuation d’une bonbonne d’Azote présente dans le poste ; * L’élimination de 2 barils d’huile (416 l au total) ; * Le remplacement complet des cellules moyenne tension existantes ; * Le renouvellement des services auxiliaires AC et DC et des batteries ainsi que l’amélioration complète des installations CVSE ; * Le renouvellement des équipements de contrôle-commande, de protection et de communication ; * L'intégration des équipements existants conservés ; * Les travaux de génie civil nécessaires ; * Les adaptations des liaisons câblées moyenne tension existantes (optionnelle); * Le transport et montage de l’ensemble des équipements fournis ; * Les essais en usine (FAT), les essais sur site (SAT), les essais fonctionnels ainsi que la mise en service complète des installations ; * La remise de l'ensemble de la documentation conforme à l'exécution. Les nouvelles cellules devront permettre une exploitation dans une première phase sous une tension de 6,4 kV puis, sans modification structurelle des équipements principaux, sous une tension de 21 kV. En conséquent, les transformateurs de tension devront être dimensionnés pour permettre ce changement de tension modifications. Les cellules devront être conçues selon une technologie sans SF₆ et de préférence isolée à l’air et compatible avec les exigences environnementales actuelles et conformes aux prescriptions techniques du présent cahier des charges et des normes en vigueurs. Les équipements haute tension (50kV) existants ainsi que les transformateurs de puissance sont conservés. Le présent marché comprend uniquement les interfaces nécessaires à leur maintien en exploitation.",
