The N117/3000 is designed for medium wind speeds (IEC-2) and has a 20 percent greater nominal output compared with its predecessor. Yet, despite this substantial increase in output, sound power levels have remained stable.
Thanks to the high towers and optimised technical systems, the N117/3000 generates high yields at IEC-2 locations.
With the N117/3000, Nordex customers are able to benefit from our more than 13 years of experience in the multi-megawatt segment.

Greater nominal output
With a nominal output of 3.0 MW, the N117/3000 has a 20 percent greater capacity than its predecessor. This results in strong additional yields in medium wind speeds.
Proven rotor blade design - increased rotor surface
The rotor fitted to the N117/3000 is 17 metres larger than its predecessor, providing around 37 percent more rotor surface. Nordex is using the proven aerodynamic design of its own NR58.5 rotor blade with carbon-fibre girders for the N117/3000.
Taller hub height
The turbine comes with taller hub heights, enabling additional gains in annual energy production and opening up complex forested sites for wind turbine installations. Thus, Nordex offers steel tube towers with a hub height of 91 metres and 120 metres for the N117/3000. The proven hybrid tower system with a hub height of 141 metres is also available.
Stable power levels
Despite the substantial increase in output, sound power levels have remained stable at 106 dB(A). What is more, Nordex offers numerous noise-optimised operating systems for particularly noise-critical locations. Thank to the improved sector-cut-out modes, an optimum yield is still achieved.
Proven drive train concept
The drive train concept is based on the proven 3-point bearing structure. The optimised drive train geometry reduces the forces impacting the individual components, thus lowering the strain on the robust rotor bearings.
Economical electrical system
As with the first wind power systems using Nordex’s multi-megawatt platform, the N117/3000 is fitted with a double-fed asynchronous generator and frequency converter. This system is characterised by superior reliability and economic efficiency.
Internally produced control system
Over 2,000 Nordex turbines have already been fitted with Nordex’s own proven Nordex Control™ system, which controls, regulates and monitors the wind power systems. Permanent and protected access to the turbine and wind farm data on site or remotely is browser-based, interactive and secure. With its modular structure and standardised interfaces, Nordex Control™ can be adjusted flexibly to meet the customer’s SCADA requirements.
Accustomed grid compatibility
The N117/3000 meets the grid requirements of the international markets. The German System Service Ordinance (SDLWindV) is one of the most demanding grid codes in Europe. With their fault ride-through capabilities, the turbines can effortlessly bridge any disruptions in voltage and thus fully comply with all requirements for the system service bonus. What is more, the Nordex Windfarm Management System allows the grid operator to directly control the active and reactive power of the windfarm in the grid.
Extended standard operating conditions
The turbine can be operated at sites with average temperatures in a normal climate range and even at temperatures of as low as -20 degrees Celsius, thus enhancing the annual yield at your site. The proven Nordex Cold Climate Package additionally helps to open up high-yield cold locations. The cold-climate version of the turbine has an extended operating range of temperatures down to -30 degrees Celsius.
The Anti-Icing System heats the aerodynamically most important surfaces of the rotor blades, thus reducing ice formation efficiently, resulting in considerable yield gains at sites characterised by frequent ice formation.
A safe and spacious work place
The turbine nacelle provides particularly safe and roomy space to work with extended escape and rescue routes. This helps to lower maintenance-induced downtimes:
