Consultation for Allocation of a New Grid Supply Point (GSP) to a GSP Group – 23 January 2020

Summary

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.

Response

If you have any views on the allocation of the above GSP to the South of Scotland GSP Group, please respond using the consultation response form, and send to bm.unit@elexon.co.uk by 17:00 on 6 February 2020.

Your response should be titled Tongland_1 GSP Consultation.

Credit Assessment Price (CAP Review) process consultation: 13 January 2020

Summary

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.

Response

Trading Parties are invited to respond to this consultation using the proforma attached. Please return responses to credit.committee@elexon.co.uk by 17:00 on Tuesday 21 January 2020.

Consultation on the Market Index Definition Statement Review 2019

Summary

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 market.operations@elexon.co.uk 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.

P350 draft reference network mapping statement for Reference Year 2018-19

Summary

We issued a consultation on the draft reference network mapping statement for Modification P350 ‘Introduction of a seasonal Zonal Transmission Losses scheme’ to each Party. The network mapping statement is used for determining Nodal power flows in the calculation of Transmission Loss Factors. 

Response

Please respond using the consultation response form and send your responses, entitled  ‘P350 Draft Reference Network Mapping Statement’, to bm.unit@elexon.co.uk  by 17.00 on Friday 13 September 2019.

Changes to the CAP Review Process: 12 August 2019

Summary

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.

P350: Methodology for Load Periods and Sample Settlement Periods Consultation 19 June 2019

Summary

Modification P350 ‘Introduction of a seasonal Zonal Transmission Losses scheme’ introduced a Transmission Loss Factor (TLF) for each TLF Zone and BSC Season, so transmission losses can be allocated on a geographical basis. P350 went live on 1 April 2018.

This Consultation details the proposed methodology for setting Load Periods and Sample Settlement Periods to be used in the derivation of Zonal TLFs, as required by the Balancing and Settlement Code (BSC).
