Registration of Balancing Mechanism Units for EMR

What do I do if I am the Registrant of CFD or CM Assets?

There are some additional BSC obligations for Lead Parties and Registrants of CFD or CM Assets. If you are the Registrant of CFD or CM Assets you must ensure that they are allocated to a BM Unit comprised solely of the CFD Assets specified in the Contracts for Difference (CFD), or the CM Assets specified in the Capacity Agreement. The BM Unit should not contain any other assets. The BM Unit should capture the metered volumes for a specific CFD or Capacity Agreement. See BSC Section K3.18 for details.

What do I do if I have CFD or CM Assets Registered in CMRS?

There are no changes to the registration processes for BM Units registered for Plant or Apparatus registered in CMRS. If you have CFD or CM Assets registered in CMRS you should follow BSCP15 3.1.

What do I do if I have CFD or CM Assets Registered in SMRS?

If you have CM Assets registered in SMRS you do not need to register Additional BM Units. Metered volumes for Capacity Providers registered in SMRS cannot provide its metered volumes via Additional BM Units to Capacity Market (CM) settlement. From the February 2015 Release Capacity Providers are able to request its Supplier to provide its metered volumes to CM settlement via its Half Hourly Data Aggregator. Please see the directed changes to BSCP503.

If you have CFD Assets registered in SMRS, Additional BM Units need to be registered. A new Additional BM Unit registration process has been established in BSCP15 3.18.  This new process allows BSCCo to register Additional BM Units under instruction of the CFD Settlement Services Provider (CFDSSP).

This process should mean that as a Supplier, you do not need to register Additional BM Units. They will be registered on your behalf if you are on the Active Power Purchasing List (APPL). Please see the Registration of BM Units for EMR guidance for more details.

Please note that as a Supplier you are obliged to register Additional BM Units and assign the Relevant CFD Assets to the Additional BM Unit if you become the Registrant of CFD Assets registered in SMRS. See BSC section K 3.3.12.

How do I know if I’m on the Active Power Purchasing List?

You will be on the list if you recorded a Half Hourly Active Export greater than zero, or requested to be added to the list via BSCP15 3.20. You should ensure you are on this list if you think you might want to take on any customers with CFDs. To ensure you’re on the list, please email EMRBMURegistrations@elexon.co.uk.

If you are not on the list, and you do take on a customer with a CFD, you may have limited time to register an Additional BM Unit. Without an Additional BM Unit the metered volumes cannot be provided to CFD settlement.This may affect the capturing  of CFD generators metered volumes and CFD settlement.  This cannot be corrected retrospectively and you will be in breach of the BSC.
