CP1543 ‘Use of DTC dataflow D0051 in the Half Hourly sector’

Assessment Report 2

The SVG rejected CP1543 at it’s meeting on 7 September 2021.

Respondents indicated they still did not feel the updated solution was suitable and the desired outcome can be achieved through other existing routes.  Following these responses the Proposer agreed with Elexon’s view the CP has not had the anticipated impact with Industry and should be rejected

Industry Consultation Period 2

CP1543 has been issued for a second Industry Consultation on Monday 12 July 2021 with responses invited by Friday 6 August 2021. 

Assessment Report 1

CP1543 was presented to the SVG at its meeting on 6 July 2021.  Following discussions with the Proposer on the back of the original Industry Consultation period the solution has been updated to send a D0051 on receipt of a D0268 (HH MTDs) as opposed to D0155 (Appointment).  We have also amended the implementation date to 24 February 2022 as part of the February 2022 BSC Release.

As a result of this a second industry consultation will take place as agreed with SVG and will be issued on Monday 12 July.

Industry Consultation Period 1

CP1543 was issued for Industry Consultation on Monday 12 April 2021 with responses invited by Monday 10 May 2021. 

Half of consultation responses indicated respondents felt the solution could be improved by reordering the redlining to send a D0051 on receipt of a D0268 as opposed to D0155.  As a result, Elexon will review this with the proposer and present the CP Assessment Report to SVG on 6 July 2021.

The CP Progression Paper was presented to SVG on 6 April 2021.  SVG provided no material comments and unanimously agreed to progress the CP to the Consultation phase.

Next Steps

CP1543 will go out for Industry Consultation on Monday 12 April 2021.

CP1543 was raised by Centrica on 6 April 2021.

Why Change?

There is currently no prescribed mechanism for HHDCs to inform a Supplier, via a dataflow, how they retrieve consumption data. This process currently relies on bilateral discussions between HHDCs and Suppliers rather than a consistent Industry-wide process. 

Without receipt of a D0051, Suppliers are reliant on informal methods of communication to understand if a Meter can be dialled remotely or not. Although not prescribed in BSCP502 some HHDCs will send a D0051 as part of the appointment process currently, but it is not an existing requirement for all to do this. This can result in Suppliers having different processes if they appoint multiple HHDCs, increasing the manual effort required to manage their portfolio.
