The decision was made by the transport secretary Patrick McLoughlin and means work can begin on the site in early-2014. The 1,289-metre quay will be available to offshore wind developers. Able UK said the site could deliver as many as 4,000 jobs.
Nearby offshore wind farms include Hornsea (4GW), Westernmost Rough (240MW) and Humber Gateway (219MW).
In August, the government signalled it was prepared to approve the facility but was requesting a report on the any environmental impact from the site. In its latest announcement Able said £60 million will be spent on the protecting the site.
Earlier this month, Strabag Offshore Wind, signed a memorandum of understanding with Able. Strabag’s investment could provide up to 500 jobs.
