In 2010 wpd bought the Butendiek project from SSE Renewables Germany Holding GmbH. After redesigning the project and a restructuring of the main work packages wpd launched the project for financing in 2011/2012. For this purpose all rights and assets regarding the project have been concentrated in OWP Butendiek GmbH & Co KG as project company.


In 2013 the final project financing with a total project volume of EUR 1.3 bn was signed by a group of five investors becoming shareholders of OWP Butendiek GmbH & Co KG: Siemens Financial Services, Marguerite Fund, Industriens Pension, PKA A/S and wpd each holding a substantial portion of the required equity. Later on CDC Infrastructure as well as ewz joined as further investors. In addition to its role as shareholder, wpd remains responsible for project management as general partner.

Debt finance is provided by a consortium of twelve banks, involving multilateral institution like European Investment Bank, KfW and EKF supporting the project with significant funds. Project debt financing has been arranged by KfW IPEX, UniCredit and Bremer Landesbank, in a consortium with European Investment Bank, KfW Förderbank, Denmark’s Eksport KreditFonden and further commercial banks including BayernLB, HeLaBa, HSH Nordbank, ING, Rabobank and SEB.
