Under the Capacity Market Rules, Capacity Providers are required to provide a baseline demand (in MW) for all Demand Side Response (DSR) CMU Components starting six weeks prior to the start of the next Delivery Year. During a System Stress Event, this baseline can be compared with the actual demand to determine the volume of capacity generated through DSR at that DSR CMU Component.
This year the deadline to provide the baseline metered data for the 2025/26 Delivery Year is by 5:00pm on Wednesday 20 August 2025. This is exactly six weeks prior to the start of the Delivery Year on 1 October 2025.
You must have your metering pathways setup by this deadline so that you can provide six weeks of metered data before the start of the Delivery Year.
For guidance on setting up your metering pathways, please refer to step 5 of our Stakeholder Support for Capacity Providers webpage. Additionally, WP195 – CM & CfD Metered Data provides information on submitting metered data before the start of the Delivery year.
