Global law firm Dentons has advised Qualitas Energy on the acquisition of DunoAir Windpark Panung GmbH, the German onshore wind development business of DunoAir. The transaction expands Qualitas Energy's wind farm development portfolio capacity in Germany by 1.4 GW to a total of 2.9 GW, a figure that is expected to increase to 6.2 GW within the next two years through its ambitious investment plan in the country. This transaction strengthens its position as a major player in the renewable energy sector in Germany.


Based in Trier, Germany, DunoAir Windkraft Planung GmbH focuses on the planning and construction of wind power plants in Germany, with a primary focus on the western part of the country. Its existing portfolio of wind power development projects has a capacity of 1.4 GW. The company will keep its organizational structure and will continue to operate under the same brand.


Qualitas Energy is a leading investment and management platformfocused on renewable energy, energy transition, and sustainable infrastructure investment. Since 2006, Qualitas Energy has managed investments of more than €11 billion in renewable energy worldwide. Qualitas Energy’s existing portfolio currently holds more than 5 GW of operating and development energy assets, including more than 3 GW of wind, 1 GWp of solar PV, 242 MW of solar thermal power (CSP), 243 MW of battery, and 435 MW of renewable natural gas assets across Spain, Germany, the UK, Italy, and Poland.


A cross-border Dentons team from Germany and the Netherlands provided both legal and tax advice on this transaction. Partners Dr. Thomas Dörmer and Dr. Tim Heitling led the cross-border team on the deal.The team specializes in transactions in the energy and infrastructure sectors and has already advised the client on several transactions, most recently in early 2023 on a partnership with Surplus Equity Partners to build a 200 MW wind farm portfolio.
