CP1497: Commissioning information data flows for HHMOAs

Formal title: Introduction of data flows for Half Hourly Meter Operator Agents to pass on Commissioning information when there is a Change of Agent

Summary

Elexon has proposed to MRASCo that two new dataflows be introduced as part of the Metering System Commissioning process. The new dataflows will allow Licensed Distribution System Operators (LDSOs), Suppliers and Meter Operator Agents (MOAs) the ability to exchange information using the Data Transfer Network. Change Proposal (CP) 1496 ‘Introduction of two data flows for the Commissioning process for Half Hourly (HH) Supplier Volume Allocation (SVA) Current Transformer (CT) operated Metering Systems’ will allow those two dataflows to be reflected in Balancing and Settlement Code (BSC) Subsidiary Documents.

CP1497 will introduce the use of the same set of Commissioning dataflows as detailed in CP1496.  These dataflows are firstly used in the new connection process for the LDSO, MOA and Supplier to complete the Commissioning process. However this CP relates to the Change of Agent (CoA) process following the new connection process. Furthermore the CP will facilitate the passing of Commissioning information when there is a CoA.

The introduction of these dataflows will enable a more efficient way for the passing of Commissioning information from the old MOA to the new MOA. Additionally this will enable the old MOA to advise the new MOA and/or Supplier of any defects or omissions to the process that arose during the Commissioning process, prior to the CoA (or concurrent change of Supplier) taking place.

During the P283 Technical Assurance Performance Assurance Parties (TAPAP) checks that were performed in 2016, feedback from industry (this included responses from LSDOs, MOAs and Suppliers) indicated that a dataflow would make fulfilling Commissioning obligations in the new connection process more efficient.
