The projects are a 500MW wind farm near Le Tréport, northern France, and 500MW near the islands of Yeu and Noirmoutier, western France.
The consortium is being led by GDF but includes Portugese renewable company EDP Renewables, French developer Neoen Marine and French manufacturer Areva. The projects, which are due to be built before 2020, are set to feature Areva's 8MW turbine.
A competing consortium of EDF Energies Nouvelles, WPD and Alstom was also in the running for the tender.
GDF Suez teamed up with Areva to pitch in the first round, but its bid for the 750MW project at Le Tréport was rejected by the government because the proposed tariff was too high. Le Tréport was then offered again, but with the capacity reduced to 500MW.
Following that setback, GDF Suez established a 50:50 joint venture with EDP Renewables for the second bid.
In 2012, a consortium led by EDF Energies Nouvelles emerged the clear winner of the first offshore tender, taking home three of the four projects awarded. Officials awarded tenders for four offshore wind sites, all located on France's north coast, with a total capacity of 1.9GW, to two consortiums led by French utility EDF, and Spanish utility Iberdrola.
On announcing the results of the latest tender energy minister Segolene Royal confirmed the French government's commitment to building 6GW of offshore wind by 2020.
