Those interested in testing marine technology at Wave Hub can find more information about the infrastructure, site management, consenting and commercial setting below.
The Wave Hub offshore site is connected to the onshore substation by a live 33kV subsea power cable arrangement which is installed as follows:
The latest safety information relating to the subsea cable system can be found in the Notice to Mariners section and a outline cable system schematic is available for download below.
Wave Hub offers grid-connection at either 11kV or 33kV. The two Wave Hub circuits may be operated at either 11kV or 33kV (uniquely, the two circuits may be safely operated at the two voltage levels simultaneously). The system has an agreed export capacity of 30MW with a total potential capacity of 48MW. Grid connection is via the Western Power Distribution 132/33kV Bulk Supply Point at Hayle.
The onshore substation houses 33kV and 11kV switchgear, a 11kV/33kV transformer and power factor correction equipment. This equipment connects the offshore technology to the grid and ensures delivery of power produced is always compliant with the relevant grid codes.
The substation also houses project communications equipment to facilitate the remote control, metering and monitoring of the deployed technology. This is achieved via fibre optic cables within the cable system and onwards via secure high speed internet connectivity. Project data and associated IT equipment is segregated and secure. Secondary satellite or device to shore radio communication is also an option to developers using the site.
Power metering is required at the lead device for an array and at the substation exit breaker. The Wave Hub SCADA (supervisory control and data acquisition) system collects offshore meter data and facilitates substation switching including central emergency shut-down.
Wave Hub holds a grid connection agreement with Western Power Distribution which defines the required parameters for electrical quality. Projects will be required to operate within these parameters which reflects Grid Code Compliance.
Marine safety management is core to Wave Hub Ltd's mission of providing a safe and effective site for marine renewable device and array testing and validation. Our operational management system is clear and pragmatic and fosters cooperative, efficient and innovative working.
All operators shall work to their own safety management systems but are also encouraged to proactively communicate and coordinate with other site users. We facilitate and support this through an innovative online operations planning and notification system.
Wave Hub Ltd provides an overall site safety monitoring, communications and central emergency response function.
Wave Hub Ltd will grant an under-lease for an area of seabed defined for the project to a customer for an agreed term. A berthing agreement will detail the respective responsibilities of Wave Hub Ltd and customer.
Wave Hub has a Power Purchase Agreement (PPA) so that all power generated can be sold into the UK trading system. Proceeds from the sale of the electricity will be transferred to customers in proportion to their generation in accordance with the terms of the PPA.
The Wave Hub offshore site has the following outline attributes:
You can download an offshore location plan and site plan at the bottom of this page. Further safety information relating to these offshore assets is available on the Wave Hub Notice to Mariners page.
Wave Hub was granted consent in 2007 under Section 36 of the Electricity Act 1989. This allows a wide variety of different wave energy generation technologies to be deployed at the site.
Wave Hub also has a licence under Section 34 of the Coastal Protection Act 1949 (CPA) and licences under Part II of the Food and Environmental Protection Act (FEPA) 1985 for the installation of the Wave Hub and subsea cable and for the protection of these by rock armouring.
Full details of our consent and decommissioning programme can be found in the downloads area.
Developers coming to Wave Hub need to apply for their own Marine Licence. The Wave Hub team will advise and support these applications which will be able to draw on the existing environmental and other baseline data.
The Wave Hub team has recently applied to the Marine Management Organisation for a Section 36 consent for the deployment of up to 40MW of floating wind within the existing Wave Hub site. Details of the application, Environmental Statement and supplementary information can be viewed online in the MMO's Public Register at http://www.gov.uk/check-marine-licence-register. A copy is also available for inspection during normal office hours at Chi Gallos, Hayle Marine Renewables Business Park, North Quay, Hayle, Cornwall TR27 4DD. The consultation period ends on 7th December 2018.
As well as providing a location where wave devices can be demonstrated over several years, Wave Hub has been established with extensive baseline data to enable any project environmental impacts to be determined accurately.
Visit the downloads area to view the various studies that made up the Environmental Statement that supported Wave Hub’s original consent application.
The scope of ongoing environmental monitoring will be determined in collaboration with the Marine Management Organisation through individual customers’ Marine Licence applications.
