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.

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).

Response

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: market.operations@elexon.co.uk.

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.

DWG’s consultation on transitioning to Market-wide Half Hourly Settlement
