Support on the use of congestion revenues for offshore renewable energy projects connected to more than one market

The objective of this report is to assess market-based options to alleviate the potential risk for the business case of offshore renewable energy when OBZs are established, and to propose concrete policy options and recommendations on the way forward. To this end, the report is structured as follows: first, we describe the current mechanisms by which congestion income is calculated and allocated. As a complement, we provide in a second section an overview of the evolution of congestion income over recent years in the EU. Third, we analyse the case of hybrid offshore assets and why their unique situation calls for specific measures in order to create a level-playing field with other (onshore) assets. In section 4, we consider a range of dedicated options to mitigate the issue and evaluate them. Section 5 provides legal requirements for implementing these options before we then conclude and provide recommendations on the way forward.
