![]() ![]() ![]() The British National Grid has another next interconnector, known as the Viking Link, planned to connect the UK and Denmark in 2024. ![]() For example, wind farms in the UK can now export surplus power of up to 1.4 GW to Norway, and then, when the wind isn’t blowing hard, the Norwegian grid can send its surplus electricity from its hydropower plants over to consumers in the UK across a 720-kilometre subsea cable. Plug into Bergen’s hydropower… in LondonĪdditional interconnector cables are being built over vast distances, as well, to share capacity between national power networks. Each turbine needs to be connected by cable to an offshore step-up substation, and then the electricity from the wind farm is transmitted to the national power grid, again by subsea cable. For most of the history of the offshore industry, electrical cable connections have been within fields between a few platforms, mostly close together and not especially numerous.īut between now and 2030, Clarkson estimates that more than 18,000 new offshore wind turbines will be installed worldwide, compared to just 7,000 which were in service at the end of 2020 ( here). The offshore wind revolution is creating unprecedented demand for offshore cable installation. ![]()
