We are unique in our ability to manage risk across diverse markets globally

Our business model is to take projects through the complex development process, to de-risk them and sell them at a point between financial close and commercial operation.

We will manage the construction and, in some cases, the operation of the plant through contracts with the long-term owner.

We have sold our projects to global utilities EDF Group and Ørsted as well as to infrastructure funds, pensions funds and global brands such as IKEA Group.
