Electric Cables: Scotland

Question: To ask the Secretary of State for Trade and Industry (1) what methodology was used by Ofgem to assess the Beauly Denny transmission line; and what account was taken of the grid reinforcement to accommodate intermittent generation, with particular reference to (a) the increase in capacity made available through the installation of equipment to permit operational intertripping and (b) the use of hydro-electricity as a balancing service when economically justified;

Answer: Under the UK's energy market framework it is for the licensed transmission network companies to connect new generation to the electricity grid. It is a matter for Ofgem, the independent regulator, to ensure that any proposals for extensions to the existing system are economic and efficient. It is for the planning process to consider if proposed upgrades are acceptable. In Scotland, those planning decisions rest with Scottish Ministers.
