The manufacturer obtained the AW3000 model through its merger with Acciona in 2016.
The increased blade length of the updated AW140/3000 turbine comes from an integrated extension at the root of the blade, Nordex said.
The machine is optimised for low-wind conditions with the broader rotor adding 12% more swept area and increasing its annual energy production by between 4.5% and 6.5%, the company added.
The AW140/3000 can be installed on 120-metre concrete towers as well as steel towers with hub heights from 82 to more than 100 metres.
The 140-metre rotor is the largest rotor of any machines in Nordex’s 3MW class, but it is nine metres shorter than its N149/4.0-4.5 — the company’s highest yielding onshore turbine revealed last month.
A prototype of the AW140/3000 will begin operation in mid-2018, the company said.
Nordex expects to receive type certification for the turbine that same year before series production, which the manufacturer expects to start in the autumn.
Nordex has completed orders for more than 4.4GW of AW3000 turbines in 13 countries, it claimed.
