Background to P344 ‘Project TERRE’

P344 ‘Project TERRE’ seeks to align the Balancing and Settlement Code with the European Balancing Project TERRE (Trans European Replacement Reserves Exchange) requirements. This will allow the implementation of the TERRE balancing product at national level and ensure compliance with the European Electricity Balancing Guideline (EBGL).

The BSC Panel has recommended to the Authority (at its 14 June 2018 meeting) that it approve the P344 Alternative Modification (mandatory sharing of Half Hourly (HH) delivered volumes with the customer’s Supplier) and reject the Proposed Modification (customer consent required for sharing HH delivered volumes with the customer’s Supplier).

The Authority approved P344 Proposed Modification on 24 August 2018 for implementation on 28 February 2019 (February 2019 BSC Release).
