Senvion
Former German wind-turbine manufacturer that developed from REpower Systems and entered insolvency in 2019.
Last updated August 31, 2026
Overview
Senvion was a German wind-turbine manufacturer headquartered in Hamburg. The business was established in 2001 under the name REpower Systems through the combination of several German wind-energy and engineering businesses, including HSW (Husumer Schiffswerft), the engineering consultancy Pro+Pro, wind-turbine manufacturer BWU, and Jacobs Energie. Its formation brought together manufacturing, project-development, and engineering capabilities at a time when Germany was becoming one of the world’s most important wind-power markets. The company supplied equipment for onshore and offshore wind projects and developed a range of turbines for utility-scale renewable-energy generation. Its business operated in a highly competitive industry in which manufacturers faced pressure from falling turbine prices, changing subsidy systems, project delays, and increasingly price-driven auction mechanisms. Senvion’s products included the 3.4M104 and 6.2M152 turbine models, reflecting its participation in both larger onshore projects and offshore or other high-capacity applications. From 2007 to 2015, Senvion was owned by Suzlon, the Indian wind-turbine manufacturer. In April 2015, the company came under the ownership of Centerbridge Partners, a private-equity firm. The business subsequently traded under the Senvion name; REpower Systems SE had adopted the Senvion identity in 2014. Although it remained an important international supplier, the company struggled with industry-wide pricing pressure and financial stress. Senvion filed for insolvency in German courts in early April 2019. As part of the subsequent restructuring and wind-down process, Siemens Gamesa acquired Senvion’s European service business and an approximately 9 GW European service fleet in October 2019. The transaction transferred service responsibilities and installed-base support rather than preserving Senvion as an independent full-scale turbine manufacturer. In 2021, Saudi Arabian company Alfanar acquired Senvion’s Indian division. These transactions marked the progressive break-up of the business. Senvion is therefore best understood as a defunct wind-energy equipment brand whose technology, service activities, and regional operations were transferred to other companies.
History
Senvion originated in Germany in 2001 under the name REpower Systems. The company was created through the merger of several businesses associated with the German wind industry: HSW, also known as Husumer Schiffswerft; Pro+Pro, an engineering consultancy connected with Denker&Wulf and aerodyn Energiesysteme GmbH; wind-turbine manufacturer BWU; and Jacobs Energie. This combination gave the new enterprise a broader base in turbine engineering, manufacturing, and wind-project development. During its early development, REpower participated in the expansion of Germany’s wind sector and built an international business supplying turbines for onshore and offshore projects. The company later became part of Suzlon, an Indian wind-turbine manufacturer, which owned it from 2007 until 2015. In 2014, REpower Systems adopted the Senvion name, establishing the brand used during the later part of its corporate history. In April 2015, Centerbridge Partners became the company’s owner. Senvion continued to market wind turbines internationally and developed models such as the 3.4M104 and 6.2M152. Its business included not only the sale of turbine equipment but also the servicing of installed machines. The company’s European service portfolio eventually represented approximately 9 GW of installed capacity, making after-sales maintenance and fleet support an important part of the business. The wider wind-turbine industry became increasingly difficult for manufacturers. Auction-based procurement and growing competition placed pressure on equipment prices, while turbine makers also faced the capital requirements and execution risks associated with large projects. Against this background, Senvion experienced financial difficulties and filed for insolvency in German courts in early April 2019. The insolvency process led to the transfer of important assets and activities rather than a continuation of Senvion as an independent manufacturer. In October 2019, Siemens Gamesa acquired Senvion’s European service fleet and related service activities, covering about 9 GW of capacity. This transaction preserved support for many turbines while moving the customer-service operation to another major industry participant. In 2021, Alfanar, a Saudi Arabian company, acquired Senvion’s Indian division. The disposal of these regional activities completed the progressive separation of the former company’s operations. Senvion is consequently recorded as a defunct German wind-turbine brand, with parts of its service network and regional business absorbed by successor owners.

Products and positioning
International wind-turbine manufacturer serving utility-scale renewable-energy projects, with roots in the German wind-power industry and a substantial European installed-service base.
Senvion 3.4M104Onshore wind turbine
The 3.4M104 was a Senvion wind-turbine model associated with the company’s utility-scale turbine portfolio. Its designation indicates a 3.4 MW class machine with a rotor diameter of approximately 104 metres. It represented Senvion’s effort to provide higher-capacity equipment for commercial wind projects and formed part of the product family marketed before the company’s insolvency.
Senvion 6.2M152High-capacity wind turbine
The 6.2M152 was one of Senvion’s largest named turbine models, rated at 6.2 MW and equipped with a rotor diameter of approximately 152 metres. The model demonstrated the company’s focus on high-capacity wind generation for demanding utility-scale applications, including projects requiring substantial output from each turbine. The product is no longer marketed by Senvion as an independent manufacturer.
