100kW Wind Turbines with Direct-Drive Technology for On-Site Generation
Harness permanent-magnet direct-drive technology to produce clean, reliable energy — at any site, in any climate. From distributed wind energy projects to off-grid and commercial & industrial applications.
The Technology Behind Our 100kW Wind Turbines: Gearless PMDD Architecture
Cutting-edge direct-drive, permanent-magnet architecture for high efficiency and low maintenance
NPS wind turbines are built on a permanent magnet direct-drive (PMDD) generator design — a gearless architecture that eliminates the gearbox entirely, reducing moving parts and maximising long-term reliability.
Unlike conventional geared turbines, our 100kW direct drive wind turbine connects the rotor directly to a low-speed permanent magnet generator, paired with a full-power converter for smooth grid integration and optimised performance even at low wind speeds — starting from just 3 m/s.
With no gearbox to service or replace, lifetime maintenance costs are significantly lower and turbine uptime is consistently higher. The platform is engineered to operate in environments ranging from arctic cold to tropical heat, making it one of the most versatile distributed wind energy solutions available in its class.
The result: more energy captured, fewer site interventions, and a stronger return on investment — whether for remote sites, microgrids, or commercial & industrial self-consumption.
40 Years of Continuous Innovation in Direct-Drive Wind Technology
Every generation of NPS turbines represents a milestone in permanent magnet wind turbine engineering. From our first 100kW proof-of-concept in 1999 to the current NPS 100C series — certified for global markets including the US (UL 1741 SB), UK (G99), and Europe (CE, DiBT, VDE) — each iteration has been shaped by real-world operational data and continuous R&D.
With 900+ installations across 30+ countries and over 79 million operating hours logged, NPS is one of the most field-proven manufacturers of gearless direct-drive wind turbines worldwide.

NPS 100kW Wind Turbine Models: Four Rotor Configurations for Every Wind Class
A range of power ratings and rotor sizes to match site-specific conditions
Our 100kW direct drive wind turbine range includes four models — each sharing the same PMDD gearless platform, optimised for a different wind resource. Whether your site is high-wind coastal or low-wind inland, there is an NPS configuration engineered for maximum annual energy output.
NPS100C-21
High Wind Class
Designed for high-wind sites, the NPS 100C-21 features a 21-metre rotor optimised for stability, structural efficiency, and consistent energy output under strong wind conditions.
Its compact rotor diameter reduces aerodynamic loads at high speeds, extending component lifespan and lowering long-term maintenance costs — while the gearless PMDD drivetrain ensures full performance without the mechanical wear typical of geared turbines.
Ideal for coastal locations, exposed ridgelines, and industrial sites where wind speeds regularly exceed 7–8 m/s. The NPS 100C-21 is also the preferred configuration where tower height restrictions or visual impact constraints apply.
NPS100C-24
Medium Wind Class
The NPS 100C-24 is the most versatile model in the range — engineered for average wind conditions and designed to deliver a strong annual energy yield across the widest variety of site types.
With a 24-metre rotor paired with our permanent magnet direct-drive generator, this model balances energy capture and structural load, making it the go-to choice for commercial & industrial self-consumption projects, agricultural installations, and behind-the-meter applications.
Its broad wind class compatibility means it performs reliably across continental Europe, North America, and most mid-latitude markets.
NPS100C-27
Low Wind Class
Engineered specifically for low-wind environments, the NPS 100C-27 combines a larger 27-metre rotor with our gearless permanent magnet direct-drive system to maximise energy capture at low wind speeds.
The increased swept area allows the turbine to extract significantly more energy from slower, less consistent airflows — making this model the ideal 100kW wind turbine for inland agricultural sites, forested terrain, and distributed wind energy projects where wind resources are moderate.
The NPS 100C-27 is one of our most widely deployed configurations globally, and is particularly well suited for self-consumption projects in the commercial and industrial sector seeking to reduce grid dependence and energy costs.
NPS100C-28
Very Low Wind Class*
The NPS 100C-28 is our largest rotor configuration, developed specifically for very low wind sites where maximising annual energy production requires extracting every available kilowatt-hour from slow, diffuse airflows.
With a 28-metre rotor diameter and our proven PMDD gearless drivetrain, this model is designed to be economically viable in locations that would otherwise be considered marginal for wind energy — opening up new opportunities for distributed generation in inland Europe where there is very low wind speed.
Currently available for EU markets only, the NPS 100C-28 is the recommended solution for agricultural operators, rural industrial facilities, and energy communities seeking maximum yield from low-wind sites without compromising on reliability or certification compliance.

Tower Configurations: Matching Hub Height to Your Site and Wind Class
Choose the optimal tower height and foundation solution to match your terrain, wind class, and installation needs.
Every NPS 100kW wind turbine can be configured with four tower options — 21 m, 30 m, 37 m tubular steel, or tilt-up — to match your terrain, permitting constraints, and target energy yield.
The tilt-up tower is particularly suited to off-grid and remote distributed wind energy installations: it requires no crane and can be combined with a ballast foundation, enabling full installation without concrete and complete removal at end of life.
37 m tower
The 37 m tower is our standard configuration, designed for low and very-low wind sites where higher hub height significantly increases annual energy output.
Its tubular steel design ensures durability and low vibration levels, making it suitable for a wide range of soil and climatic conditions.
30 m tower
A balanced choice for medium-wind environments, the 30 m tower provides optimal energy production while keeping structural loads low.
This configuration is the most commonly selected option for commercial and agricultural installations, offering a great compromise between yield and accessibility.
21 m tower
Compact and easy to install, the 21 m (+2 m for ballast foundation = 23 m hub height) tower configuration is ideal for high-wind sites or locations with visual or permitting constraints.
It offers simplified logistics, lower foundation requirements, and maintains full turbine performance thanks to the efficiency of the direct-drive system.
Tilt-up tower
The tilt-up tower solution enables easier installation and maintenance — particularly in remote or off-grid areas without heavy lifting equipment.
It can be combined with a ballast foundation, allowing the entire system to be installed without concrete, simplifying permitting and enabling full removability at end-of-life.
This makes it a cost-effective and sustainable alternative for temporary or relocatable projects.
