On 1 October 2021, we received a proposal from the Electricity System Operator (“ESO”) to make amendments to the national terms and conditions related to balancing (“T&C”) required by Article 18 of Commission Regulation (EU) 2017/2195 establishing a guideline on electricity balancing (the “EBGL Regulation”), as amended by the Electricity Network Codes and Guidelines (Markets and Trading) (Amendment) (EU Exit) Regulations 2019. This proposal relates to an update of the Short Term Operating Reserve (“STOR”) Assessment Principles which is part of the suite of documents that make up the STOR service conditions.
This letter sets out our decision to approve that the proposed amendments to the STOR service conditions, as mapped by the ESO, form part of the T&C pursuant to Article 18 of the EBGL Regulation.
