Consultations on Operations and Settlement
This page lists all Consultations relating to Operations and Settlement. The consultations allow ELEXON to gather feedback from the industry about proposed changes so that any concerns are considered as part of our processes.
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.
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 email@example.com by 17:00 on 6 February 2020.
Your response should be titled Tongland_1 GSP Consultation.
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.
Trading Parties are invited to respond to this consultation using the proforma attached. Please return responses to firstname.lastname@example.org by 17:00 on Tuesday 21 January 2020.
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.
Please email your responses using the pro-forma below to Credit.Committee@elexon.co.uk by 17:00 on Tuesday 24 December 2019.
ELEXON has received a new GSP registration application from the National Electricity Transmission System Operator (NETSO). UK Power Networks (South Eastern Power Networks) (SBPN) is connecting two new circuits into the Richborough 132kV substation. This new Systems Connection Point will be registered in Settlement as a new GSP, to be known as Richborough GSP (RICH_J).
The NETSO proposes that GSP RICH_J is allocated to the South Eastern (_J) GSP Group.
If you have any views on the allocation of the above GSP to the South Eastern GSP Group, please respond using the consultation response form, and send to email@example.com by 17:00 on 12 November 2019.
Your response should be titled ‘Richborough GSP Registration’.
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.
Please respond using the consultation response proforma and send your responses, entitled ‘MIDS Review 2019 Consultation’, to firstname.lastname@example.org 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.
This consultation seeks respondents’ views on increasing the CAP £54/MWh from the last notified value of £43/MWh.
Please email responses to Credit.email@example.com using the pro-forma below by 17.00 on Tuesday 17 September 2019.
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.
Please respond using the consultation response form and send your responses, entitled ‘P350 Draft Reference Network Mapping Statement’, to firstname.lastname@example.org by 17.00 on Friday 13 September 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.
ELEXON has received a new GSP registration application from the Transmission Company. National Grid Electricity Transmission (NGET) is connecting a new GSP at Islington, which will form a connection between the existing High Voltage 400kV substation at Highbury and the UK Power Networks Distribution System in the London region. This new GSP will be known as Holloway/Islington (GSP_HOLL_1).
The Transmission Company propose that GSP HOLL_1 is allocated to the London (_C) GSP Group.
If you have any views on the allocation of the above GSP to the London GSP Group, please respond using the consultation response form, and send to email@example.com by 17:00 on 5 July 2019.
Your response should be titled Holloway/Islington GSP Registration.
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).
We encourage you to respond to this consultation using the consultation pro-forma. The consultation period will end on Friday 5 July 2019 at 17:00. Please return responses to: firstname.lastname@example.org.
At the end of the consultation period, ELEXON will consider all responses and, if required, update the methodology accordingly. The methodology, along with all consultation responses, will be presented to the Imbalance Settlement Group (ISG) meeting next month to request approval of both the methodology and actual LPs and SSPs.
Upon approval, ELEXON will publish the actual LPs and SSPs on the website on or before 31 August 2019.
