Electricity
(asked on 5th February 2016) - View Source
Question to the Department for Business, Energy and Industrial Strategy:
To ask the Secretary of State for Energy and Climate Change, what the spare capacity is in each of the national electricity grid systems from which the UK buys electricity through interconnectors.
The security of supply contribution that interconnectors to other countries can make is assessed annually, based on detailed market modelling to determine anticipated electricity flows from connected markets at times of GB system stress. An overview of the 2015 assessment can be found here:
In addition, there are arrangements in place for interconnectors to provide emergency response services to the System Operator outside of usual market operation. This includes reducing any exports to zero in the unlikely event of coincident stress with connected markets.
