Unmetered Supplies Data Service

2. Additional Info

Background 1.1 The Employer is National Highways the government company charged with operating, maintaining and improving England’s motorways and major A roads, including modernising and maintaining the highways. We also manage - and help prevent - incidents on England’s motorways through our Traffic Officer Service. The Employer manages around 4,300 miles of carriageway and is made up of motorways and trunk roads. 1.2 National Highways (hereafter referred to as the Employer) procures un-metered electrical energy from bulk electricity suppliers, for its road lighting and lit traffic signs on Motorways and Trunk Roads in England. 1.3 As these electricity supplies are unmetered and traded Half Hourly (HH), the Service Information is required to conform to an industry procedure BSCP520 (Balancing and Settlement Code Procedure) and a Meter Administrator (MA), must be appointed. 1.4 In June 2023 all customers using Unmetered Supply (UMS) will be required to move to Market Wide HH Settlement. National Highways historically has traded HH electricity so this should have negligible impact, the meter administrator would now be known as the Unmetered Supplies Data Service. 1.5 The Service covers all of the DNO (Distribution Network Operator) Areas in England and some sections of Scotland and Wales: www.ofgem.gov.uk/electricity/distribution-networks/gb-electricity-distribution-network. 2 Overall objectives 2.1 This Service Information is based on BSCP520, but incorporates the necessary requirements of the Employer to enable the Service to be provided on a National basis. 2.2 The general requirements (including the role, responsibilities and functions of the appointed Contractor) are as defined in BSC Procedure BSCP520 and later BSCP700. 2.3 The Employer currently uses PECU Arrays (Photo Electric Control Unit) and Central Management Systems (CMS) in the process for obtaining HH (Half Hourly) consumption data and will in the future wish to take advantage of potential cost savings associated with ‘Dimming’ and/or ‘half-night operation’. Therefore, the Equivalent Meter (EM) used will need to be able to accommodate these factors so it will be necessary for the Contractor to be Central Management System (CMS) approved.
