Type of Testing Tidal Year Established 2017 Temperate/Tropical Temperate Commercial/Array/Full scale/Scale Development Status Operational Overview
The site is located in the Garonne, downstream from the Pierre de Pierre bridge in Bordeaux, 100 kilometres away from the mouth of the Gironde estuary. It is exposed to major currents influenced by the diurnal tidal cycle of the Bay of Biscay and by the flow of freshwater rivers from the Garonne and Pyrenees catchment area.
SEENEOH is operated by a team made of 4 companies specialised in one of the key sectors of tidal energy project: environmental monitoring (Energie de la Lune), mechanical engineering (Cerenis), Electricity production and communication (Valorem), Safety and security (Valemo), administrative and finance (SEML). -
