The SEM Trading and Settlement Code specifies that the Market Operator and the System Operators shall make reports to the Regulatory Authorities proposing values for four groups of parameters for each Year at least four months before the start of that Year. The groups of parameters concerned are:
- Parameters for the determination of Required Credit Cover (SEMO);
- MSP Software Penalty Cost Parameters (SEMO);
- Parameters used in the calculation of Uninstructed Imbalances (TSOs); and
- Flattening Power Factor (TSOs).
The RAs have received the reports from SEMO and the TSOs in respect of the values they propose should apply for the Year 2018. The purpose of this consultation is to seek views from interested parties on the proposals from SEMO and the TSOs. All comments should be received by close of business Friday, 6 October 2017.
Because of the go-live of the I-SEM arrangements on 23 May 2018, these values will only apply from 1 January 2018 until I-SEM go-live.
