Formal title: Changes to support the implementation of the SRAG’s recommendations

Current Status

CPC Consultation
Committee Decision
Awaiting Implementation


Currently, there are no processes set out for elective Half Hourly (HH) Settlement of smart Meter data. Therefore, changes to the relevant BSCPs are needed to set out the processes required where the Supplier, rather than the Half Hourly Data Collector (HHDC), retrieves HH data.


New processes are needed for:

  1. the exchange of HH data between the Supplier and HHDC;
  2. data validation and estimation for smart Meters;
  3. informing the HHDC of the Supplier’s reading schedule (i.e. when to expect HH data);
  4. allowing Suppliers to send cumulative register readings to the Licensed Distribution System Operator (LDSO).


The existing data flows for transferring HH data hold HH values to the nearest 100Wh. However, Meters that meet the requirements of the SMETS are capable of providing data to the nearest Wh, and HH data for smaller customers will need to be processed to the nearest Wh. Data flows between the Supplier and HHDC, and between the HHDC and Half Hourly Data Aggregator (HHDA), need to reflect this greater precision.


Additionally, the Settlement Reform Advisory Group (SRAG) recommended removing the requirement for Proving Tests (a test that shows the HH data at the Meter matches that collected by the HHDC) for Metering Systems with smart Meters.


Elexon raised CP1469 on 19 July 2016. The CP Progression paper was presented to the Supplier Volume Allocation Group (SVG) on 2 August 2016. The CP Consultation closed on 2 September 2016.  The SVG approved CP1469 at its meeting on  4 October 2016. CP1469 will be implemented on 29 June 2017 as part of the BSC June 2017 Release.
