Nordex upgrades N175/6.X turbine to 7.3 MW and new 179m tower gains approval
Nordex Group has announced three related updates to its N175/6.X wind turbine platform: a higher power mode of 7.3 megawatts (MW), a new concrete-steel hybrid tower option in Germany that reaches 179 meters. A TÜV SÜD type approval for a 587‑foot (about 179 meters) hybrid tower built with partner Max Bögl. The announcements were made on April 22, 2026, and are aimed at increasing energy yield, flexibility in hub height, and speeding regulatory certification. This explainer breaks down what changed, who is affected, and practical next steps for developers and buyers.
What changed in brief
The Nordex N175/6.X platform now includes: (1) a new 7.3 MW power mode to extract more energy from wind, (2) a 179-meter concrete-steel hybrid tower option for the German market that increases hub height. (3) TÜV SÜD type approval for a 587-foot (about 179 meters) hybrid tower built with partner Max Bögl. All three updates are part of the Delta4000 onshore turbine family. The timing suggests a coordinated push to improve yield, height flexibility, and certification efficiency across markets with strict local standards.
Key facts you should know
- Single platform: All updates relate to Nordex's N175/6.X within the Delta4000 generation.
- Power increase: The turbine can operate at 7.3 MW in a specific power mode, raising potential annual energy production per turbine.
- New tower option in Germany: A 179-meter concrete-steel hybrid tower is offered to extend hub height, which can improve wind capture in some sites.
- TÜV SÜD certification: The 587-foot hybrid tower received safety and performance certification, which can help with permitting and market access.
- Regulatory context: Tower height and certification are major factors in project timelines in markets like Germany.
Who is affected
Wind farm developers and operators using the N175/6.X platform in Europe, especially in Germany, stand to benefit from higher power output and greater hub-height flexibility. Certification improvements may shorten permitting and grid-connection processes for projects considering these taller towers. Components suppliers and service partners may need to align with new tower designs and testing requirements.
Practical next steps
- Developers: Assess site wind resources and layout to determine if 7.3 MW mode and taller towers improve capacity factor for planned projects.
- Permitting teams: Reference the TÜV SÜD certification when engaging local authorities for projects using the 587-foot tower to streamline approvals.
- Procurement: Consider the new 179-meter tower option as part of bidding packages for German sites or where local standards favor tall towers.
- Technical teams: Review turbine control strategies to safely operate at the higher power mode and ensure grid compliance for increased output.
