A multi-criteria methodology to select the best wave energy sites

This paper presents a methodology to choose the best locations for wave energy projects around the coast. It is based on a multi-criteria assessment methodology that considers physical, environmental and socioeconomic constraints. The proposed decision making tool can be customized by the final user according to different systems and implementation conditions. A set of factors (wave energy criteria, bathymetry, distance to coastline and ports, seabed …) are considered for the final selection. The tool is tested over a large area. It can also be used for a specific area, if sufficient geospatial data are available with good accurate spatial resolution. The methodology is applied to the French Atlantic coast. Brittany and the south western of France are most suitable for wave energy devices deployment.
