On 14 September 2018, we received two methodologies from the relevant Transmission System Operators (TSOs) in accordance with Articles 118 and 119 of Commission Regulation (EU) 2017/1485 (“the SOGL Regulation). The methodologies contain the proposals required by Articles 118 and 119, that are relevant to GB, including those requiring our approval. The methodologies were submitted to us by the Electricity System Operator (ESO) in line with our assignment of obligations.
This letter sets out our decision to request amendments to the documents. The letter furthermore outlines the necessary next steps that must be taken.
