I-SEM CRM Capacity Requirement and De-Rating Methodology Decision published
The Integrated Single Electricity Market (I-SEM) High Level Design includes a Capacity Remuneration Mechanism (CRM) to ensure that sufficient generation is available to keep the lights on. The CRM will secure the capacity required to produce electrical energy through the I-SEM via a competitive reliability options auction process.
The RAs today publish this CRM Decision Paper regarding the methodology for determining the capacity requirement associated with the CRM auction design and the de-rating factors to be applied to capacity providers.
This paper is published following a consultation process and industry engagement. It contains a summary of the comments received during the consultation, the SEM Committee’s response to those comments and the SEM Committee’s decisions on the key issues.
