The SEM Committee has today 07 October 2026, published a decision paper on SEM Operational Parameters for 2027.
Under the terms of the SEM Trading and Settlement Code (TSC), the Regulatory Authorities (RAs) shall determine certain parameters proposed by the Market Operator (MO) and the TSOs, as applicable, in relation to the calculation and treatment of participants' Required Credit Cover and matters related to Imbalance Settlement.
In May 2026 the RAs requested SEMO to review the parameters utilised in the calculation of Required Credit Cover and of the Settlement Recalculation Threshold.
On 17 July 2026, the RAs received reports from SEMO (SEM-26-43a) and (SEM-26-43b) outlining their recommendations for the proposed values for the above parameters. The RAs subsequently published a consultation paper (SEM-26-43) on 10 August 2026, requesting the view of market participants on SEMO's and the TSOs' recommendations.
This paper presents the RAs' decision in relation to the operational parameters for 2027.
