Scheduling and Dispatch Parameters Decision Paper 2024
The SEM Committee has today, 29 October 2024, published a decision paper on SEM Scheduling and Dispatch Parameters for 2025.
Under Condition 10A of EirGrid’s Transmission System Operator (TSO) Licence, and Condition 22A of SONI’s Transmission System Operator Licence, the System Operator (SO) is required to report to the Regulatory Authorities (RAs) proposing values for parameters to be applied in the Scheduling and Dispatch process.
In May 2024 the RAs requested the TSOs to review the following parameters utilised in Scheduling and Dispatch:
1. Long Notice Adjustment Factor (LNAF)
2. System Imbalance Flattening Factor (SIFF)
On 5 July 2024, the RAs received a report from the TSOs (SEM-24-054a) outlining their recommendations for the proposed values for the above parameters. The RAs then published a consultation on 26 August 2024 (SEM-24-054) on the TSO’s recommendations.
This paper presents the SEM Committee’s decision in relation to these parameters.
