Change Proposal: CP1490

Changes to BSCP27 and Technical Assurance Agent Service Descriptions to remove constraints to service improvement

Proposer: ELEXON

Current Phase: Awaiting Implementation

Lead Analyst: Chris Wood

Categories: CVA, SVA

Responsible Panel Committees: Imbalance Settlement Group (ISG), Supplier Volume Allocation Group (SVG)

Implementation Date: 22 February 2018


Technical Assurance is carried out by a Technical Assurance Agent (TAA) on both Central Volume Allocation (CVA) and Supplier Volume Allocation (SVA) systems. It ensures that the Active Energy Imported and/or Active Energy Exported through Boundary Points and System Connection Points are complete and accurate. Technical Assurance is also used to assess the overall health of the Half-Hourly Metering System population.

The SDs for CVA and SVA specify that an online management tool is provided by the TAA for reporting and evidence capturing following an inspection visit. The technology provision and meter inspection functions are two distinct functions and there are limited options in terms of providers that can carry out both roles.

CP1490 proposes that the TAA is not required to provide an online management tool for accessing and amending information. Instead, the TAA should simply be required to provide management information in the manner that is agreed in the arrangements between the TAA and ELEXON. The separation of assurance and IT service provision will give ELEXON more options in terms of choosing suitable companies.


ELEXON raised CP1490 on 7 June 2017. It was presented for information to the ISG on 27 June 2017 and to the SVG on 4 July 2017. CP1490 was issued for CP consultation on 10 July 2017 with responses due by 4 August 2017. CP1490 closed to consultation on 4 Aug 17. CP1490 will be presented for decision to the ISG on 22 August 2017 and the SVG on 5 September 2017.
CP1490 was approved by the ISG on 22 August 2017 and the SVG on 5 September 2017.
