The subsea link is to be built in Scotland between Kintyre and Hunterston and will supply an additional 150MW of extra grid capacity.
The energy supplier said the plan was given the green light following a positive reception from regulator Ofgem.
Adding resilience to the network
The connection has been in the works for a number of years and is expected to enable the development of local renewable energy projects. The initiative will see the creation of a twin subsea cable link which will connect a new substation, Crossaig, to Hunterston.
The subsequent ‘green’ energy projects which will be developed as a result of the upgrade will provide an alternative source of energy and add to the overall resilience of the network.
Scottish Hydro Electric Transmission is currently finalising plans for construction but has yet to announce when work will begin. The initiative is part of SSE’s £5bn scheme to modernise the electricity network in Scotland between 2013 and 2021.
David Gardner, director of transmission at SSE, said: “The announcement from Ofgem signals another significant step in our plans to reinforce the transmission infrastructure throughout Scotland.
“Along with completion of key projects within our approved budget of £1.4bn, including good progress on Beauly Denny, this project demonstrates that we are gaining momentum on our capital expenditure programme which will connect significant amounts of renewable energy to the grid; contributing to energy security, economic growth and decarbonisation of electricity generation.”
