Consultation on Proposals for Implementing SGU Requirements re Data Exchange

25.01.2019 On the 14th September 2017, the Commission Regulation (EU) 2017/1485 establishing a guideline on electricity transmission system operation (SO GL) entered into force. Article 40(6) of SO GL required all TSOs to agree on Key Organisational Requirements, Roles and Responsibilities (KORRR) relating to Data Exchange. KORRR was approved by the All Regulatory Authority on 19th December 2018, and will serve as the basis for what TSOs, DSOs and Significant Grid Users (SGUs) will need to do to comply with Articles 41 to 53 of SO GL. TSOs, DSOs and SGUs will need to comply with KORRR from 14th March 2019.

SGUs are the target audience of this consultation. SGUs are as defined under Article 2(1) of SO GL, which are;

(a) existing and new power generating modules that are, or would be, classified as type B, C and D in accordance with the criteria set out in Article 5 of Commission Regulation (EU) 2016/631;

(b) existing and new transmission-connected demand facilities;

(c) existing and new transmission-connected closed distribution systems;

(d) existing and new demand facilities, closed distribution systems and third parties if they provide demand response directly to the TSO in accordance with the criteria in Article 27 of Commission Regulation (EU) 2016/1388;

(e) providers of redispatching of power generating modules or demand facilities by means of aggregation and providers of active power reserve in accordance with Title 8 of Part IV of SO GL; and

(f) existing and new high voltage direct current (‘HVDC’) systems in accordance with the criteria in Article 3(1) of Commission Regulation (EU) 2016/1447.

The requirements of KORRR apply to new and existing SGUs.

Under Article 40(5) of SO GL, the TSO is required to co-ordinate with DSOs and SGUs within its Observability Area on the applicability and scope of data exchange. Also, under Article 40(7) each TSO is to reach an agreement with relevant DSOs on the processes and formats of data exchange between them. The purpose of this consultation is:

  • To define the TSO’s and DSO’s proposed applicability and scope of KORRR.
  • To enable the accurate incorporation of SGU interactions under KORRR to the TSO-DSO agreement.
  • To provide SGUs with clear information of the TSO’s and DSO’s proposed SGU commitments under KORRR, and a mechanism for SGUs to provide feedback to the TSO and DSO ahead of the TSO-DSO agreement in March 201

Current data exchange practices are already largely aligned with KORRR. As a result, the proposals in this KORRR consultation align with current practices and the requirements of the Grid Code and Distribution Code. EirGrid is seeking your feedback on a number of proposals which reflect this, with the below documents available for download:
