Summary

The Grid Code Electricity Balancing System (EBS) Working Group has been progressing changes to the Dynamic Data Set. This Modification Proposal seeks to ensure that the Dynamic Data Set published on the BMRS fully corresponds to the revised Dynamic Data Set as submitted to the Transmission Company by BSC Parties.

P297 will have an impact on BSC Parties as the new and revised Dynamic Data items will affect the relevant TIBCO messages and the BMRS Website.

Progression

National Grid has informed ELEXON that they will not be in a position to deliver the data necessary for P297 to be implemented in BSC Systems by 1 November 2018. National Grid’s IS Forum in July will present and discuss with industry the revised roadmap of IS delivery which will include P297. An update on National Grid’s plans for P297 will be provided to the BSC Panel no later than September 2018.

P297 was raised by National Grid on 24 July 2013.

The Initial Written Assessment was presented to the BSC Panel at its meeting on 8 August 2013. The Panel agreed for P297 to progress to the Assessment Procedure with the Assessment Report to be submitted to the Panel at its meeting on 14 November 2013. At this meeting, the Panel agreed to send P297 back into Assessment for the Workgroup to further develop the solution and to discuss the new requirements.

Following the second Assessment Procedure Consultation responses, the updated Assessment Report was submitted to the Panel at its meeting on 13 February 2014. The Panel initially unanimously recommends that P297 is approved. The P297 Report Phase Consultation was subsequently issued with responses due on 6 March 2014. The Draft Modification Report was presented to the Panel at its meeting on 20 March 2014, who made its final recommendation that P297 should be approved. P297 was approved by the Authority on 28 April 2014, for implementation on 5 November 2015 as part of the November 2015 BSC Systems Release.

The Panel requested a revised Implementation Date for P297 of 3 November 2016 (November 2016 Release) at its meeting on 12 February 2015. The Authority approved this revised Implementation Date on 16 March 2015. The revised Implementation Date was due to the EBS go-live date being delayed until July 2016.

Due to further EBS delays, the Panel requested a revised Implementation Date for P297 of 29 June 2017 (June 2017 Release) at its meeting on 9 June 2016. The Authority approved this revised Implementation Date on 8 August 2016.

National Grid has since confirmed that EBS cannot be delivered in 2017. On 28 April 2017,  National Grid wrote a letter to ELEXON stating that due to delays with the delivery of EBS, they needed to request a deferral to the date of the implementation of P297 to November 2018. On 11 May 2017, the Panel requested a revised Implementation Date for P297 of 1 November 2018 (November 2018 Release). The Authority approved this revised Implementation Date on 28 June 2017.
