Summary

National Grid ESO TERRE Derogation impact on CP1517

CP1517 will implement documentation required for go-live of P344 ‘Project TERRE’ functionality. This P344 functionality is also required to facilitate wider market access to the Balancing Mechanism (BM), which we intend to go-live with in December 2019, irrespective of the outcome of National Grid ESO’s derogation request to Ofgem to delay its participation in the Project TERRE balancing product to no later than December 2020. Therefore, we are still working to implement CP1517 to enable wider access to the BM in December 2019.

 P344 was implemented on 28 February 2019. This was one of two Implementation Dates set for P344:

  • The P344 Relevant Implementation Date, which was 28 February 2019 as part of the February 2019 Release; and
  • The P344 Final Implementation Date, defined as the date specified in the P344 Final Implementation Date Notice (to be issued by National Grid Electricity System Operator).

On the Relevant Implementation Date all Sections of the Balancing and Settlement Code (BSC) and its subsidiary documents, where the solution was known and so could be amended, became effective.

There are several BSC Configurable Items (CIs) which need to be amended to give full effect to the TERRE solution that could not be developed in time to become effective on 28 February 2019, or which should only become effective on the TERRE Final Implementation Date. This is because the changes relate to the new and amended software or the new BSC Services that will be introduced on that date.

 CP1517 was raised by ELEXON on 17 May 2019. It seeks to amend the Configurable Items (CIs) to give full effect to the TERRE solution that could not be developed in time to become effective on 28 February 2019, or which should only become effective on the TERRE Final Implementation Date.

We anticipate that CP1517 will impact:

  • Virtual Lead Parties
  • Suppliers
  • National Electricity Transmissions System Operator (NETSO)

Progression

CP1517 was raised on 17 May 2019 and published for consultation on the same day, with responses due by 13 June 2019.

As a result of the responses we received to the CP1517 consultation (and other work we are doing with our service provider to finalise the P344 solution) we identified a number of minor changes and clarifications. Therefore,  CP1517 was issued for a second consultation on the 8 July 2019 , with a response deadline of the  2 August 2019. 

CP1517 was approved by the ISG on the 20 August 2019. CP1517 was Approved to the SVG on 3 September 2019 .

 

Next Events

CP1517 will be implemented on the P344 Final Implementation Date Notice ( as defined in BSC Section H ‘General’) - as a Standalone Release.
