Paimpol–Bréhat tidal farm

The Paimpol–Bréhat tidal farm is a tidal stream turbine demonstration site, located northeast of Île-de-Bréhat near Paimpol, Brittany, France. It was initially developed by Électricité de France (EdF), initiated in 2004 and construction work began in 2008, but the project was subsequently cancelled by EdF in 2018. This project was to use OpenHydro turbines, with two briefly installed in 2016, but they were later removed. Paimpol–Bréhat is now used as a test site, owned by EdF and managed with support from Seeneoh and Bretagne Ocean Power. In September 2022, the 2 MW three-phase AC grid connection was upgraded, allowing devices to be connected above the water without the need for divers. The test site is about 10 km offshore and covers a rectangular area approximately 140 m × 250 m. Water depths vary across the site at 26 m to 42 m below LAT, with a tidal range of about 11.5 m. Telemac 2D modelling gives a depth averaged velocity on a medium spring tide peaks at around 2.1–2.8 m/s. French developer HydroQuest tested a 1 MW turbine called OceanQuest at Paimpol–Bréhat between April 2019 and December 2021.
