  • Network output measures

    Ensuring we deliver value for money

  • 6 January 2014

    The UK's onshore electricity transmission network owners shape how we will run our businesses over the coming eight years under the recently introduced RIIO-T1 price control regime. 

    The new regime introduced of a set of measures aimed at ensuring that transmission owners invest consumers' money wisely in their networks; We need to make sure we minimise costs for current customers without creating unnecessary costs for future customers. In conjunction with Ofgem, we use network output measures to show we are investing in our existing assets appropriately. 

    Our methodology sets out how we calculate these measures, based on factors including asset condition and criticality to the network. We updated it recently to reflect the current regulatory arrangements and asked for your views on our proposed changes. You can read the amended methodology statement with our proposed changes below. The last date for comment was 7 February 2014, but if you have any questions, please send an email to

  • Energy not supplied (ENS) incentive mechanism – October 2011

    One of our key objectives outlined in our July Business Plan is to keep the lights on for our customers in the north of Scotland. A component of keeping the lights on is ensuring that loss of supply incidents on the transmission system are kept to a minimum. We were keen to ensure that any mechanism adopted to promote this reflects the interests of our customers and as such we appreciated your thoughts on the proposals laid out in the consultation document. 

    This consultation closed on 11 November 2011, and a summary of the response and our informed position on this can be found in our Summary of ENS consultation responses.
