The partnership will see Force 9 initially complete plans on behalf of EDF Energy Renewables for a number of new wind farms across the British Isles.
EDF Energy Renewables will take over the wind farm projects when planning consents have been agreed. A pipeline of further wind turbines projects could then follow.
Christian Egal, Chief Executive of EDF Energy Renewables said: "EDF ER is very happy to enter into a long term development agreement with Force 9, providing access to a proven onshore wind energy development team with an enviable track record."
Force 9 Managing Director David Butterworth said: "EDF Energy Renewables is very keen to develop well sited, economic and environmentally positive wind energy projects and we are looking forward to a strong partnership with them to achieve this."
