Change Proposal: CP1495

Introduction of a rejection response dataflow for a D0170 ‘Request for Meter System Related Details’ request from the Meter Operator Agent to the Licensed Distribution System Operator where a D0215 ‘Provision of Site Technical Details’ response is required.

Proposer: ELEXON

Current Phase: Assessment

Lead Analyst: Chris Wood

Category: SVA

Responsible Panel Committee: Supplier Volume Allocation Group (SVG)

Implementation Date: It is proposed to implement as part of the June 2018 release

Summary

ELEXON has proposed to MRASCo that a new D0170 rejection response dataflow be introduced to allow Licensed Distribution System Operators (LDSOs) to inform Meter Operator Agents (MOAs) that they do not hold certain information in regards to requests for site technical details. CP1495 proposes changes to BSC Code Subsidiary Documents to reflect the introduction of the new dataflow.

The process for ‘new connections’ or a ‘change of measurement class’ in Balancing and Settlement Code Procedures (BSCP) 514 – ‘SVA Meter Operations For Metering Systems Registered in SMRS’ and BSCP515 – ‘Licenced Distribution’ include when MOAs should request Metering System related details from LDSOs (dataflow D0170). Normally, the LDSO would respond with the required details (dataflow D0215). However, there may be reasons why the LDSO is unable to provide the requested information. At the moment there is no formal means by which the LDSO can notify the MOA that they don’t have the required information. This information may be passed informally (e.g. by e-mail), if at all, and even then, there are cases where the reason for rejection may not be given.

Where certain Metering System equipment is owned by the LDSO, commissioning is the LDSO’s responsibility. Where the equipment is not owned by the LDSO, the MOA is then responsible for Commissioning. If the LDSO is not able to notify this formally, then the MOA may not be aware of their obligation towards Commissioning. There is therefore a risk that data will be submitted from Metering Systems that haven’t been proven to be accurate, which could lead to inaccurate Settlement data. The flow of accurate and expedient information between the relative groups will reduce delays in Commissioning and participation in Settlement and hence reduce the associated financial implications.

Progression

CP1495 was raised on 2 October 2017. it will be presented to the SVG for information on 31 October 2017 ahead of being issued for consultation between 6 November and 1 December 2017. CP1495 will return to the SVG in January 2018 for decision.

CP1495 is being raised alongside MRASCO DTC CP 3523
