Scotland’s SSEN seeks approval for 220 MW power cable in Scotland [free access]

March 5, 2018

The British utility Scottish and Southern Electricity Networks (SSEN) has submitted a Strategic Wider Works (SWW) Final Needs Case for the 220 MW Orkney­­–Scotland subsea power transmission project to the British regulator Office of Gas and Electricity Markets (Ofgem).


The transmission link would initially comprise a single 220 kV subsea cable scheduled for completion in October 2022, followed by a second similar cable once further generation is committed and considered as economic.


As reported, the Orkney Islands are estimated to have significant renewable energy potential, from tidal, onshore and offshore wind. According to SSEN, the network infrastructure required to provide the transmission connection to Orkney is currently under development and is subject to planning approval.
