Issue 96

Formal title: Assessing the reporting to EMRS of chargeable volumes for SVA Metering Systems that record both exempt and licensed supply

Current Status


The Balancing and Settlement Code Company (BSCCo) is required to provide to the Electricity Market Reform Settlement company (EMRS) the BSC Metered Volumes it requires to accurately calculate Capacity Market (CM) and Contracts for Difference (CFD) charges. This Issue seeks to explore enduring solutions which allow correct reporting to EMRS of chargeable volumes for Supplier Volume Allocation (SVA) Metering Systems that record both exempt supply and licensed supply. There is currently no process that allows for allocation of appropriate volumes where a portion should be exempt and another portion should be licensable.

Three potential solutions have been identified currently. The Issue Group should explore these solutions, any alternatives, and recommend which, if any, to take forward.


Issue 96 was raised by UC Energy Ltd on 6 August 2021. The first Issue 96 meeting was held on Friday 10 September 2021 where four different potential enduring solutions for exempt supply were discussed. 

The second Issue 96 Workgroup meeting was held on Wednesday 16 March 2022, where detailed proposals for the two shortlisted options were discussed in more detail. The WG decided that a Modification should be progressed for option 3, to create the Exempt Supply Calculation Agent (ESCA) role. 

Meeting documents including the slides and a summary of what was discussed can be found on each meeting page. 

Next Events

A third Issue 96 Workgroup is currently being organised, and this will discuss a newly developed option that could also be progressed.  If you would like to join or be added to the distribution list, please let us know by sending an email to [email protected]
