Transporter response to actions. AMR004: Transporters (CW) to provide supporting justification as to why, and what type of AMR asset information they believe they would require in a future unbundled solution and whether or not it is appropriate for them to specify AMR equipment standards
Transporter response to actions AMR005: …consider what constitutes an appropriate upper threshold level for DM Mandatory sites and whether more rigorous business rules will be needed in the unbundled world.
Transporter requirements for AMR information in an unbundled DM regime Current requirements: Information provided split into Firm and Interruptible Supply Points 6 a.m. daily read Hourly reads provided every 4 hours Daily data Required for energy settlement/allocation FTi Hourly data Required for system operation (incl emergency & interruption management) Re-sync information resulting from maintenance & or fault investigation.
Transporter requirements for AMR information in an unbundled DM regime Inappropriate for Transporters to be specifying equipment standards.
DM eligibility No aspiration to amend DM mandatory threshold which appears optimal. Business rules anticipated to be more rigorous than DME given: requirement for ‘within day’ data implications to the industry of non-receipt of accurate and timely reads for daily settlement.
Possible next steps DM data requirements ‘wider’ and more complex than the issues identified under Project Nexus Unbundling benefits could in principle be realised ahead of Project Nexus timescales subject to appropriate funding Consideration should be given to progress initiative as separate development outside of Project Nexus remit Could be UNC Modification Proposal raised for development within UNC Distribution Workstream? Scope to address all aspects of existing DM regime (DMM, DMV, telemetry, etc).
