Credit Assessment Price (CAP) consultation: 10 August
We are consulting on an increase of the CAP to £46/MWh from the current CAP value of £36/MWh. A change to CAP can impact the amount of Credit Cover required by a Trading Party.
Credit Assessment Price (CAP) consultation: 6 July 2020
The Credit Assessment Price (CAP) is used in the Energy Indebtedness calculations to convert Credit Cover into an energy value.
Issue 89 Request for Information
The BSC Panel has asked Elexon to provide analysis on the cost and effort related to the DCE that occurred on 9 August 2019 (DCE00201). We are looking specifically at those costs incurred by parties, both direct and indirect, associated with the SAP that are required to be carried out to ensure Settlement is accurately calculated for the Settlement Periods impacted by the DCE. This analysis is being carried out for Issue 89 and P397.
The provision of this information is critical to meet the aim of Issue 89, to ensure the SAP is fit for purpose, and the aim for P397, to only run the SAP when the benefits outweigh the costs. Moreover, the provision of this information is needed to meet the Ofgem request in relation to P397. Your help and support in this matter is appreciated.
Credit Assessment Price (CAP) consultation: 25 March 2020
The Credit Assessment Price (CAP) is used in the Energy Indebtedness calculations to convert Credit Cover into an energy value.
We are consulting on a decrease of the CAP to £32/MWh from the last notified value of £36/MWh. A change to CAP can impact the amount of Credit Cover required by a Trading Party.
If all respondents and Credit Committee members are in agreement, the proposed value will be implemented on Wednesday 15 April 2020, 10 Business Days after the consultation closes. The trigger level will also decrease to
+/- £3/MWh.
If at least one respondent or Credit Committee member requests it or disagrees with the proposed value, Elexon will arrange a Credit Committee meeting.
The Credit Committee will determine if a change needs to be made to the value of the CAP, the trigger level and when any new value should be implemented.
Outcome
No responses were in disagreement with the new suggested CAP value. However today, Monday 30 March, the Reference Price is £29.68/MWh, and therefore the Credit Committee decided to confirm a new CAP value of £30/MWh.
On Thursday 16 April 2020, the CAP value will decrease from £36/MWh to £30/MWh. As a result, Parties may notice a change in their Credit Cover Percentage, and should review the amount of Credit Cover lodged.
The CAP review trigger level value will also reduce at +/- £3/MWh.
Credit Assessment Price (CAP) consultation: 10 February 2020
This consultation seeks respondents’ views on decreasing the CAP £36/MWh from the last notified value of £41/MWh.
Outcome
No responses were in disagreement with the new suggested CAP value. As such, no Credit Committee meeting was held and the proposed CAP value was implemented on the date stated in the consultation.
Consultation for Allocation of a New Grid Supply Point (GSP) to a GSP Group – 23 January 2020
The Tongland 132kV substation currently feeds the _N GSP Group via two circuits with 132/11kV transformers, which form the existing GSP, GSP_TONG. The existing GSP is at the 11kV substation.
Scottish Power Energy Network (SPEN) is connecting two new circuits into the Tongland 132kV substation. The two new circuits will be connected via 132/33kV transformers to a 33kV substation. The new circuits at the 33kV substation will be registered as a new GSP, to be known as Tongland_1, GSP_TONG1.
The National Electricity Transmission System Operator (NETSO) propose that GSP_TONG1 is allocated to the South of Scotland (_N) GSP Group.
Credit Assessment Price (CAP Review) process consultation: 13 January 2020
The Credit Assessment Price (CAP) is used in the Energy Indebtedness calculations to convert Credit Cover into an energy value. We are consulting on a decrease of the CAP to £41/MWh from the last notified value of £47/MWh. A change to CAP can impact the amount of Credit Cover required by a Trading Party.
If all respondents and Credit Committee members are in agreement, the proposed value will be implemented on Wednesday 12 February 2020 and the trigger level will remain the same.
If at least one respondent or Credit Committee member requests it or disagrees with the proposed value, Elexon will arrange a Credit Committee meeting. The Credit Committee will determine if a change needs to be made to the value of the CAP, the trigger level and when any new value should be implemented.
Outcome
No responses were in disagreement with the new suggested CAP value. As such, no Credit Committee meeting was held and the proposed CAP value was implemented on the date stated in the consultation.
Credit Assessment Price (CAP) review consultation: 16 December 2019
This consultation seeks respondents’ views on decreasing the CAP to £47/MWh from the last notified value of £54/MWh.
This change can affect the level of Credit Cover that you are required to lodge, so we encourage you to respond to the consultation.
If at least one respondent or Credit Committee member requests it, Elexon will arrange a Credit Committee meeting after the consultation closes to determine the new CAP value.
Outcome
No responses were in disagreement with the new suggested CAP value. As such, no Credit Committee meeting was held and the proposed CAP value was implemented on the date stated in the consultation.
Consultation for Allocation of a New Grid Supply Point (GSP) to a GSP Group – 30 October 2019

Consultation on the Market Index Definition Statement Review 2019
The Market Index Definition Statement (MIDS) defines the use of Market Index Data to calculate the Market Index Price (MIP), a price reflective of wholesale electricity for a Settlement Period in the short term market. An annual review of this document is required by the BSC, to ensure that the MIP is providing a reasonable reflection of the price of wholesale electricity in the short term market.
Changes were made to the MIDS as part of BSC Modification P377 ‘Amending Gate Closure references in Market Index Data’, which was implemented on 18 April 2019.
Our yearly analysis suggests that there are no further changes to the MIDS required at this time, with the current Individual Liquidity Threshold (ILT), timeband weightings and product weightings remaining suitable.
Response
Please respond using the consultation response proforma and send your responses, entitled ‘MIDS Review 2019 Consultation’, to [email protected] by Thursday 10 October 2019.
Responses to this consultation will be considered by the Imbalance Settlement Group at its meeting on 22 October 2019, where a final recommendation will be made to the BSC Panel for approval.

Changes to the CAP Review Process: 12 August 2019
We invite Trading Parties to indicate whether they agree with the proposal to set new CAP values based on the estimated reference price on the implementation date of the new CAP. We also invite Parties to indicate if they agree the trigger level (the value from which if the reference price deviates by, then a review of the CAP is triggered) should be automatically set. These proposed changes will allow for a more efficient process whilst maintaining the necessary levels of control.
