Senvion S.A. (formerly REpower Systems SE) is a wind turbine manufacturer founded in 2001 in Germany, now majority owned by the private equity firm, Centerbridge Partners. Registered business address is in Luxembourg. Its product range comprises several types of turbines with rated outputs of between 1.8 and 6.15 megawatts.

Senvion was formed in 2001 from the merger of the company Jacobs energy with HSW (Husum Shipyard), "BWU" and "pro + pro energy systems" (a subsidiary of aerodyn energiesysteme and Denker & Wulf). The roots of this company go back to 1994, when the first self-developed 500-kilowatt system was presented. Previously, the configuration and operating company "Denker & Wulf" was founded in Sehestedt in 1995. This was, however, sold to the interim consolidated financial affiliation with REpower, in 2004.

Senvion started to produce the ProTec MD, a 1500 kW turbine. This turbine designed by "pro + pro energy systems" was licensed also to "Jacobs Energie", Nordex SE, Südwind and Fuhrländer. Later own designs like 2MW, 3MW and 5MW turbines are follow.

In May 2007, after efforts by its largest shareholder Areva to take a controlling interest in the company, a series of protracted bidding rounds resulted in not Areva, but Suzlon Energy of India acquiring the majority shareholding in REpower Systems for €1.3 billion. The deal was structured in such a manner to allow Suzlon to purchase Martifer's stake (22%) within two years for a fixed price of €265 million. Suzlon subsequently strengthened its position by buying the remaining 30% Areva stake in June 2008 for more than €350 million. Suzlon's total investment of approximately US$ 1.6 billion gives it a holding of 66%, with the next largest shareholder being Martifer of Portugal. Areva went on to purchase the majority holding in 5MW rival, Multibrid. In 2009 Suzlon raised its share to 92% of REpower. As of February 2015, Suzlon Energy owns 100% of Senvion, but subsequently sold the company to Centerbridge Partners LP. in April 2015. The Company was then listed on Frankfurt Stock Exchange Prime Standard on 23rd March 2016 at a valuation of €1bn.

The Senvion 5M 5-megawatt turbine was the largest commercial turbine until the subsequent upgrade of this unit to provide significant more power, named "6M". This has a rated output of 6.15 megawatts from the same rotor diameter of 126.5 meters. The target market is the offshore wind farm sector. The prototype was assembled in the autumn of 2004 in Brunsbüttel, located in the German state of Schleswig-Holstein. In August 2006 the first 5M model was erected for the Beatrice project. The Senvion 6MW turbine with the same rotor diameter has been operational in Elhöft, Germany since 2009, well ahead of any other turbine manufacturers in this class in the world.
