Project objective

The project objective is to develop offshore grid concepts that integrate the functions of offshore wind farm connection and cross-border trade, leading to lower levelized transport costs and higher margins for both the wind farm operator and the grid operator. The study focused on interconnecting two planned offshore wind farms in the UK and Dutch part of the North Sea, considering a broad number of aspects, including solutions for technical design and operation, economic feasibility and alternative financing methods and legal and regulatory aspects.

Expected outcome

The project has resulted in a number of integrated offshore grid solutions that are both technically and economically feasible, i.e. with sound prospects for return on investment, and couldbe operational before 2023. Therefore the main recommendations from the project are (1) to consider these integrated solutions and to study these already in the early planning phase of a project and (2) to immediately start to resolve the existing legal and regulatory issues that prevent the realization of these integrated solutions that involve different countries. Further, alternative financing solutions, like green bonds and real options, have been evaluated, legal solutions have been formulated and the implementation and cost reduction potential of distributed cable monitoring has been studied.
