Our modular offshore solar farm has been operational at sea for several years now and as we are extending it, we are monitoring it extensively. Specifically, the environmental monitoring we do thoroughly. Together with knowledge institutes, NGO’s and universities, we assess the impact on nature and marine life as well as to explore nature-enhancing opportunities around offshore solar
