P344 IWG 2: Allocation of SVA MSID to SBMUs

This industry working group is developing the processes and the associated Code Subsidiary Documents (CSDs) changes required to implement two requirements of the P344 ‘Project TERRE’ solution. These requirements are:

  • The notification to the Supplier Volume Allocation Administrator (SVAA) of which MSID Pairs should be treated as belonging to a SBMU by the Virtual Lead Party of that SBMU
  • The maintenance of a register (the “SVA Metering System Balancing Services Register”) of which SVA MSIDs belong to each SBMU for purposes of providing Balancing Mechanism (BM) or Replace Reserve (RR) Services.

Background to P344 “Project TERRE”

P344 ‘Project TERRE’ seeks to align the Balancing and Settlement Code with the European Balancing Project TERRE (Trans European Replacement Reserves Exchange) requirements. This will allow the implementation of the TERRE balancing product at national level and ensure compliance with the European Electricity Balancing Guideline (EBGL).

The BSC Panel has recommended to the Authority (at its 14 June 2018 meeting) that it approve the P344 Alternative Modification (mandatory sharing of Half Hourly (HH) delivered volumes with the customer’s Supplier) and reject the Proposed Modification (customer consent required for sharing HH delivered volumes with the customer’s Supplier).

The Authority is expected to make a decision by 31 July 2018. If approved the Modification will be implemented on 28 February 2019 (February 2019 BSC Release).
