Project Development: There from the start


The project development of renewable energy projects is an important and valuable stage of our range of services. We cover the entire value chain, from land acquisition and the approval process to construction and commissioning.


Flanked by the political framework conditions, the expansion of renewable energy plants is increasing throughout Europe. 
More and more institutional investors are securing projects for their long-term existing plants at an early stage. With our many years of experience in the development as well as the construction and operation of the plants, we accompany you as a strong and innovative partner.



With us, you are investing in the modernisation of energy provision. We are an independent and integrated asset and investment manager in the area of sustainable energy infrastructure. For us, integrated means the combination of commercial and technical knowledge when it comes to investments and ongoing operations management. Due to our longstanding experience and the proximity to the relevant asset, we achieve optimum results for our investors.


We want to work together with you long term and personally. Our employees in asset management and investment, in the areas of finance, technology and law have been in the company for around ten years and work closely together in the buying, selling and operation of assets. Therefore, a trustworthy relationship with our customers has top priority.
