SEM Scheduling and Dispatch Parameters 2021 Decision Paper

Under section 10A of EirGrid’s Transmission System Operator (TSO) Licence, and section 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 2020 the RAs requested the MO to review the following parameters utilised in Scheduling and Dispatch:

  1. Long Notice Adjustment Factor (LNAF)
  2. System Imbalance Flattening Factor (SIFF)

On 21st August 2020, the RAs received reports (i.e. SEM-20-066a) from the MO outlining their recommendations for the proposed values for the above parameters. The RAs subsequently published a consultation paper (SEM-20-066) on the 17th September 2020, which consulted on SEMO’s recommendations.

Having considered stakeholder comments, this paper presents the RA’s decision in relation to these parameters (i.e. Scheduling and Dispatch)
