Nordex launching the 2.5MW Gamma Wind Turbines in the Chinese and Asian wind energy markets

 Comprising the N90/2500kW and N100/2500kW, the Efficiency Class 2.5 MW wind turbines address the market requirements and incorporate the latest findings from research and development. In developing the Gamma generation, Nordex has remained true to proven principles, using tested series engineering and assigning top priority to the dependability of all system components, to ensure improved product quality for better power yield. Based on the over 1700 2.5.MW units already installed and experience from more than a decade of operation, the Gamma Generation is designed for all wind classes and climatic regions in compliance with international grid codes and national standards in China. The quality meets international standards and is fully in line with the 18 national regulations for wind turbine technology effective from 1 November in China.

The N90/2500 and N100/2500 wind turbines are based on a common technical platform. A consistent modular design allows Nordex to add type-specific components and customer options. Furthermore, the modular design makes delivery, installation and maintenance fast and simple.

Besides, the nacelle, hub and board crane have all been re-designed, with optimized yaw, pitch and cooling systems. Hence, the Efficiency Class can operate more efficiently and reliably.

“A new software version for Nordex Control 2 is used in 2.5MW gamma platform. With the new software, power yield is improved at partial load operation (vHub = ~ 5..10 m/s). It also helps improve output in the complete low and mid wind range, while start-up hysteresis can be improved.” Dr. Ni, Engineering Director of Nordex China stated.

Most importantly, with the company’s global installation experience, Nordex 2.5MW wind turbines comply with all known grid codes across the globe. It has outstanding grid compliance, i.e., a flexible and powerful fault ride through capability. During the process of Low Voltage Ride Through (LVRT) or High Voltage Ride Through (HVRT), the turbine can continuously output reactive power; with the adoption of new circuit topology design, Zero Voltage Ride Through (ZVRT) and fast reacting speed can be achieved. It is also worth noting that parameters can be defined to achieve flexible project-specific configurations.

“Starting from Germany, we are expanding our business across the globe with branches in 19 countries. Our subtlety, foresight and flexibility in the global and local markets have enabled us to gain strong footholds in three core regions: Europe, America and Asia. This is why we were one of the first foreign suppliers to enter the Chinese market, back in 1995.” Mr. Jens Olsen, CEO of Nordex China stressed. “In fact, we have already had one N90/2500kW wind turbine installed in Zhangbei in CEPRI’s testing wind farm. This is the largest turbine installed by a foreign company in China. Meanwhile, preparations for 2.5MW localization have started. The 16-year local experience and the local supply chain are undoubtedly our advantages, Further extension spending as well as investments in equipment and tools have been implemented at our facilities in Yinchuan and Dongying.” Mr. Jens Olsen adds.

With the demand in China increasing, Nordex will continue to make inroads in this market with its latest products.

As a technological leader among suppliers of megawatt wind turbines, Nordex benefits particularly from the global trend towards large-scale wind turbines. The product range includes one of the largest series wind power systems in the world (N80/2500, N90/2500, N100/2500, N117/2400) with more 1,700 of these turbines having been produced to date. This means that Nordex has a crucial edge in terms of experience in operating large turbines compared to most of its competitors in the sector. Overall, Nordex has installed a more than 4,600 turbines with a capacity in excess of 7,100 MW around the world. With exports accounting for over 95 percent of its business, Nordex also has a strong position in international high-growth regions. The company has offices and subsidiaries in 19 countries. In total, the Group employs more than 2,600 people worldwide.
