Energy regulator Ofgem is consulting on plans to upgrade a stretch of the electricity network on the Scottish coast for £205million.

This is one of several new projects due to be considered by Ofgem between 2013 and 2021.

The work will include two subsea cables between the Kintyre peninsula and Hunterston as well as the rest of the Scottish transmission network.

SSE’s transmission arm SHE plans to build a new substation at Crossaig and improve overhead power lines between Crossaig and Carradale. If approved, the firm would have to finish the upgrades in 2016.

The improvements to the high voltage electricity system are needed to cope with more renewable energy in Kintyre.

This consultation on funding is the first under Ofgem’s new rules to make sure firms keep costs reasonable and get new projects done on time, the so-called RIIO-T1 price control.

The costs are part of the £30 billion package announced under the regulator’s new RIIO (Revenue = Incentives + Innovation + Outputs) price control package for transmission companies.
