How was Wave Hub constructed?
A number of engineering options were considered, based on what is technically sound and achievable, has minimum environmental impact, is cost-effective and does not present significant safety and operational issues. The project connects to the electricity distribution network via a new sub-station in Hayle, Cornwall. From there, a cable runs through a duct under the sand dunes and is jointed to the sub-sea cable in a pit beneath the beach. The cable is buried in sediment for the first 5km out to sea and is then held in place by rock dumping. At the offshore site, the cable divides into four to allow four types of devices to be connected in.
