Description

The Biscay Gulf Electrical Interconnection (BGE) consists of the construction of a 2.000 MW link. This link is composed of two (2) circuits rated 1.000 MW each for DC operating voltage of 400 kV, in total comprised of four (4) power cables, four (4) converter station terminals located close to 400 kV Gatica substation (Spain) and Cubnezais substation (France). The length of the route is estimated to be approximately 400 km long starting in Spanish País Vasco region (near Bilbao) to an ending point in Nouvelle Aquitaine (Gironde department, near Bordeaux). The interconnection is composed of underground cables with total approximate route length of 115 km and submarine cables with total approximate route length of 285 km.

The project supported by European Union’s Connecting Europe Facility. Lot 1: Terrestrial Civil Works designated for the installation of four (4) power cables ducts plus optic fiber cables ducts of a total underground cable route length of approximately 15 km in Spanish side (landfall works excluded) and 100 km in French side (landfall works excluded). The scope includes the design (including detail design), engineering, procurement and construction (including trenchless solution to cross Dordogne and Garonne rivers in France and smaller sections in Spain). The lengths given are approximate and may be varied for route adjustments. The Applicants must note that to perform the works, the economic operator must be qualified for the referenced type of works in the RTE qualification system or in the REE qualification system.
