Under the contract, Vestas will supply, install and commission nine V105-3.45MW wind turbines, which the company says are optimized to meet the UK tip-height restrictions.
The order also includes a service and availability agreement (AOM4000). Vestas expects to start turbine deliver yin the fourth quarter of this year.
EDF Energies Nouvelles CEO Antoine Cahuzac said: "EDF Energies Nouvelles has plans to significantly grow its wind asset base; this long-term agreement will help us in reaching our goals as it offers the opportunity to secure flexibility and cost-efficiency for a lot of our upcoming wind projects."
Vestas Northern Europe president Klaus Steen Mortensen said: "This is the first time we are awarded a V105 project in the UK, and this once again emphasises the competitiveness and flexibility of our 3 MW platform in a market typically dominated by height restrictions and less efficient technologies.
"Both the 31 MW order and the frame agreement are the result of a close collaboration and a strong track record between EDF EN and Vestas."
Under the master supply agreement, EDF EN will buy from Vestas a minimum of 45% of its onshore wind installations in the future in Europe and a minimum of 30% of installations in the US.
The deal includes a VestasOnline Business SCADA system and the option of establishing various schemes of service and maintenance contracts in different countries in partnership with EDF EN.
