Resource Assessment

In 2025, a suite of technical baseline and metocean studies was completed for the Bretagne Nord Ouest (BNO) offshore wind study and consultation zone. The official eoliennesenmer.fr project page lists multiple 2025 reports, including a Météo-France study evaluating usual wind-related risks and an analysis of storms and extreme waves, providing detailed characterisation of the wind and wave climate over the area. Complementary 2025 syntheses by SHOM cover the initial state of tides (marée), currents, swell (houle), bathymetry, anthropogenic elements, hydrology, and sedimentology. Together these documents constitute a structured resource and environmental baseline assessment for the 350 km² BNO zone, supporting feasibility evaluation and future design work for the planned floating offshore wind project.
