Capacity Market FAQs

Below you’ll find answers to the most frequently asked questions about the Capacity Market.

Please email info@lowcarboncontracts.uk if you cannot find the answer to your question.

SPD Pass

Outstanding  

CMU Portfolios  

Why not modelled?  

They cannot be automated as it cannot be determined by ESC what CMUs are to be grouped as a portfolio.

The time saved from validating those CMUs that can be modelled means improvements to the delivery of SPDs for those that have not been modelled or where there are errors.

SPD Pass Report

If the CMU has passed its SPDs and the SPD pass report does not show this, please contact one of the Delivery Partners to enquire why this is.

ESC contact email: info@electricitysettlementscompany.uk

EMR Delivery Body: emr@nationalgrideso.com

If the CMU has not passed the SPDs, please follow the guidance, Demonstrating Satisfactory Performance & Extended Performance which can be found by following this link to the EMR Delivery Body’s guidance portal.

If a Capacity Provider's CMUs are not on the report it will be due to one of three reasons:

  • The CMU has not exceeded its AACO as per the SPD rules for the specific auction;
  • The data setup is not complete (Aggregation Rules, Metered Volume Data flows or another issue);
  • It has not been possible to automate the SPD process for the CMU type.

If the CMU has not passed the SPDs, please follow the guidance Demonstrating Satisfactory Performance & Extended Performance which can be found by following this link to the EMR Delivery Body’s guidance portal: https://emrdeliverybody.nationalgrideso.com/IG/s/

ESC started producing the report on the 31 March 2022, the new changes to Proven/Unproven DSR, Extended Performance, and Secondary Trading going live from the 1st October 2022.  

The SPD pass report is issued every 2 weeks and can be found here: https://www.lowcarboncontracts.uk/data-portal/dataset/capacity-market-spd-pass-report. 

We plan to publish the SPD Pass Report in the week commencing 28/10/2024, likely toward the end of that week once our checks are complete. By then, we expect to have around three weeks of II data.  After the first publication, we’ll publish every two weeks, like previous delivery years.

The table below outlines the publication dates for this delivery year:
