By 2030, some 20.000 km of new subsea cables are needed in the seas of Europe with an estimated investment cost of €50 billion (source: ENTSO-E). Permitting authorities are already being confronted with the need to understand impacts of offshore energy infrastructure. In view of the planned offshore expansion, the question of how to measure and deal with cumulative impacts is daunting. The risk of delayed or refused permits, in the absence of sufficient information, is real.
The challenges of undertaking so many projects in just over a decade are massive: technically, logistically and financially. We need to better understand what can be done and to learn from each other’s experiences in order to optimally make use of the infrastructure that is to be built.
During the workshop, we tried to understand the current knowledge gaps in relation to the (cumulative) impacts of marine infrastructure. Together with stakeholders, we explored what can be done to close these knowledge gaps, and how to collect relevant data and make it available to permitting authorities across borders. In addition, we discussed how grid infrastructure could be used to gather data that may contribute positively to the permitting process.
