Under the contract, Nordex will supply and install 12 N117/3000 Generation Delta wind turbines, each of which features a hub height of 141m and an installed nominal output of 3MW.
Expected to generate 119GWh of energy per year, the wind facility will be located close to the town of Kalajoki in western Finland.
Construction on the Jokela wind farm is planned to commence in mid-2015. Nordex will provide services for 15 years.
wpd country manager responsible for Finland and Sweden Birgit Schneider said: "On the basis of their technical specifications, the N117/3000 turbines are a very good fit for the local weather conditions and we are eagerly awaiting the preliminary results following the start-up of our "Mäkikangas" wind farm."
"We are confident of having found in Nordex a partner for the two wind farms capable of providing an ideal combination of technology and service."
wpd earlier ordered 11 Nordex N117/3000 turbines for its Makikangas wind farm, situated next to the Jokela project.
