Energy and environment minister Ségolène Royal wants to ensure that the zones selected are the most favourable and have widespread support, including securing the support of the fishermen's associations.
Last year the authorities identified areas with a favourable wind resource, which met various economic and technical criteria and had a possible grid connection. The results are now being discussed at a regional level to come up with concrete proposals.
Possible contenders for zones for fixed-foundation turbines include off Boulogne-sur-Mer and the Ile d'Oloron, where WPD Offshore has been working. Up to five possible zones have also been identified in the Mediterranean for fixed and floating turbines.
A tender for up to 3GW using fixed turbines is expected at the end of the year, while a call for expressions of interest for floating pilot farms should be launched June.
