Issue 60: Project TERRE

Formal title: Interfaces between the European Balancing Project TERRE and the current GB market arrangements

Project Trans-European Replacement Reserves Exchange (TERRE) is an advance implementation project that forms part of the implementation of the European Network Code on Electricity Balancing. TERRE aims to harmonise the Transmission System Operator (TSO) dispatch of Replacement Reserve (RR) across seven TSO areas from Great Britain (GB) to Greece. It will do this by introducing common TERRE Products, which would be akin to products such as Balancing and Settlement Code (BSC) Bid-Offers or Short Term Operating Reserve (STOR) submissions.

National Grid is expected to utilise TERRE Products for energy balancing in GB from TERRE go-live, which is currently scheduled for summer 2017. As all current GB balancing products feed into the BSC calculations of imbalance prices and volumes, the Proposer considers that the relevant TERRE Products should do so too, as soon as they start to be used as part of GB balancing. This will require changes to the GB market arrangements (BSC and/or Balancing Services arrangements).

Progression

Issue 60 was raised by National Grid on 8 June 2015. The sixth and last Issue Group meeting was held on 9 March 2016.

Issue 60 had been closed because no firm conclusions could be reached. The expectation is that the Modification process will provide the structure for a Workgroup to complete the work.

National Grid was of the view that the Modification needed to be raised promptly to ensure that BSC Systems would be ready for end to end testing in the autumn of 2017. National Grid aims to raise a Modification in time for the June 2016 Panel.

At its meeting on 12 May 2016, the Panel noted that Issue 60 is now closed and that National Grid will raise a Modification in time for the June 2016 Panel meeting.
