Ofgem has approved of the Eastern Green Link subsea cable enabling the transfer of renewable energy between England and Scotland.

This electric superhighway will comprise two cables with a length of 315 miles or 507 kilometres each. They will connect Aberdeenshire to North Yorkshire with most of the distance covered being under the sea.

Scottish electricity and distribution company SSEN predicts that the total project cost will be £4.3 billion. The project is to be a joint effort between SSEN and electricity and gas utility company the National Grid.

According to Ofgem, the cable will have the capacity to carry enough energy from wind farms in Scotland to meet the energy demands of up to two million English properties. The project’s completion date is set for 2029.

In the long term, a total of four subsea cables linking Scotland and England are planned. The four cables will have the capacity to provide power for as many as 7.5 million homes.

The Eastern Greenlink cables will work alongside the Western Greenlink cable that already operates connecting Ayrshire, Scotland to the English-Welsh border.
