CP1464

Formal title: Requiring HH consumption data to be processed to appropriate precision

Current Status

Submission
Assessment
CPC Consultation
Committee Decision
Rejected

Summary

The existing data flows for Half Hourly (HH) site data only provide for consumption data to be sent to BSC Parties and Supplier Agents to the nearest 100 Watt hours (Wh). However, smart Meters that meet the requirements of the Smart Metering Equipment Technical Specifications (SMETS) are capable of providing data to the nearest Wh, and the HH consumption data of smaller customers will need to be processed to the nearest Wh. CP1464 proposes to introduce an obligation on Suppliers and Half-Hourly Data Collectors (HHDCs) to process data to the nearest Wh where data to that granularity can be obtained from the Meter.

A related change is Data Transfer Catalogue (DTC) change DTC CP3492, ‘Increasing the precision of data items relating to Half-Hourly (HH) Advances’, which has been raised to change the relevant Master Registration Agreement (MRA) DTC data flow items.

Progression

CP1464 was raised by Elexon on 17 May 2016. The CP Progression Paper was presented to the SVG for information on 31 May 2016 and issued for CP Consultation on 6 June 2016, with responses due by 1 July 2016. DTC CP3492 was withdrawn on 28 July 2016 due to negative responses to the industry consultation. CP1464 was rejected by the SVG on 6 September 2016. An alternative solution of using new data flows to hold increased precision HH data is being progressed as part of CP1469 and related DTC CP3496.
