Winergy

What Winergy does

Winergy is a business segment of Flender GmbH specializing in wind turbine drivetrain solutions, founded in 1981 with the delivery of its first wind gearbox. The company serves wind turbine OEMs including Vestas, Siemens Gamesa, GE, Suzlon, Nordex, and Senvion with a vertically integrated product portfolio spanning gearboxes (up to 20 MW), wind generators (permanent magnet synchronous, electrically excited synchronous, squirrel cage induction, and doubly-fed asynchronous), HybridDrive mid-speed powertrains, Direct Drive segments, and ARPEX wind couplings. Technology differentiators include proprietary in-house journal bearings, the REVO gearbox concept achieving 300 Nm/kg torque density, and the FlexibleFit modular powertrain configuration. The company is headquartered in Bocholt, Germany, with major manufacturing in Tianjin (China), inherited operations in Finland post-Moventas acquisition, and a new service facility under construction in Melbourne, Australia.

The core technology base combines mechanical drivetrain engineering with digital monitoring products including CMaS Evolution condition monitoring and Digital Gearbox with 99.7% torque measurement accuracy. The group reports 100,000+ gearboxes delivered, 250+ GW of installed capacity with Winergy gearboxes, 150+ GW with generators and DirectDrive segments, and 350+ GW of turbines covered by CMaS Evolution monitoring. The 2022 Moventas acquisition added 20+ GW of installed base and Nordic service capability, while the 2021 integration of the Wind Energy Generation business unified the gearbox and generator organizations under the Winergy brand to enable complete powertrain delivery.

Winergy generates revenue through direct enterprise sales of new equipment to wind turbine OEMs, supplemented by a multi-decade aftermarket service franchise under the Service360 brand covering field service, spare parts, workshop service, condition monitoring, training, repowering, and new and refurbished replacement components for over 100 turbine platforms and 130+ gearbox types. Distribution combines direct OEM engagement with a Certified Service Partners (CSP) network and a 24/7 online spare parts shop. Revenue is not publicly disclosed; the company operates as a private business segment of Flender GmbH, with Flender International GmbH (Coesfeld, Germany) as the registered legal entity.

Partnerships

One partnership is on record.

• MoventascoreStrategic or Co-development Partner · 1 January 2022Winergy acquired Finnish wind gearbox manufacturer and service provider Moventas in 2022. This acquisition expanded Winergy's service coverage for legacy Moventas products (PLH-312, PLH-1400, PPLH-1100) and brought condition monitoring expertise that was integrated into CMaS Evolution. The acquisition strengthened Nordic market presence and added over 20 GW of Moventas gearbox installations to the service portfolio.

Broad incumbents

• Vestas Wind Systems: Vestas is Winergy's largest disclosed OEM customer and the world's largest wind turbine manufacturer. Comparable as a broad incumbent with vertically integrated drivetrain engineering, exerting significant pricing power over suppliers like Winergy on EnVentus and other platforms.
• Nordex Group: Nordex is a top European wind OEM (N149, N133, AW platforms) and a Winergy customer for gearboxes and service. Comparable as a broad incumbent OEM competing with Vestas, Siemens Gamesa, and GE for large turbine slots while buying drivetrains from suppliers like Winergy.
• GE Vernova (GE Wind): GE Wind (now GE Vernova) is a top-3 wind OEM and a Winergy customer (1.5–4.8 MW service). Comparable as a broad incumbent in the wind turbine market that competes both as a customer and a vertically integrated drivetrain developer in offshore segments.
• ABB (Motors and Generators / ABB NEMA): ABB supplies large industrial generators and converters applicable to wind applications, and historically competed in wind generator segments. Broad incumbent in power generation equipment with overlap on the generator side of Winergy's drivetrain offering.

Direct peers

• ZF Wind Power: ZF Wind Power is one of the largest wind gearbox manufacturers globally, supplying both onshore and offshore turbines. Direct competitor to Winergy in planetary and helical gearbox technology, with overlapping OEM customers in Europe and Asia.
• Bonfiglioli Riduttori: Bonfiglioli supplies wind turbine gearboxes (3–6 MW+) and drivetrain solutions to OEMs including Vestas. Direct competitor in wind gearbox manufacturing with similar planetary stage technology and European manufacturing footprint.
• Siemens Gamesa: Siemens Gamesa is both a customer (Winergy supplies gearboxes for SWT platforms) and a competing drivetrain designer with in-house direct-drive and geared drivetrain programs. Most directly comparable as an integrated wind turbine OEM with substantial drivetrain engineering capability.
• The Switch (Yaskawa Environmental Energy / The Switch): The Switch, part of Yaskawa, manufactures permanent magnet generators and full-power converters for wind turbines. Direct peer to Winergy's generator business, competing for generator slots on geared and direct-drive platforms.
• Eickhoff Wind Power: Eickhoff is a German manufacturer of planetary gearboxes for wind turbines (both onshore and offshore), explicitly referenced in Winergy's multibrand Service360 coverage. Closely comparable gearbox peer competing for similar Western OEM slots.
• Nidec (Nidec Industrial Solutions): Nidec supplies wind turbine generators (including direct-drive PMSG technology) and acquired larger wind generator assets from other players. Direct peer in the wind generator segment of Winergy's portfolio, competing for OEM slots especially in offshore direct-drive.
