THERE is to be a new subsea power connection from Ayrshire to the Kintyre Peninsula, where along with Arran thousands of homes were without power for four days due to snowstorms in March.

Scottish Hydro Electric (SHE) Transmission says it will spend over £200 million to upgrade the electricity transmission network between Kintyre and Hunterston after receiving positive feedback from the industry regulator, Ofgem.

The upgrade will release up to 150MW of additional grid capacity for renewable projects signalling a significant boost for the Kintyre economy. The upgrade will involve installation of a twin subsea cable link from a new substation called Crossaig to Hunterston.

The upgrade will also include a new 13.5km section of tower line between Crossaig and the existing substation at Carradale, which will largely follow the existing route. Once construction is complete, the old tower line will be removed.

This link has been planned for a number of years in order to connect renewable energy in the area. However, the project has the added benefit of providing an alternative source of power from the mainland which will increase the resilience of the network.

David Gardner, director of transmission for 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, 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."
