DWG’s consultation on transitioning to Market-wide Half Hourly Settlement
The DWG has developed its approach for transitioning from the current Settlement arrangements to the Target Operating Model (TOM) for Market-wide Half Hourly Settlement (MHHS).
This consultation is your opportunity to comment on the transition approach as developed by the DWG, before Ofgem makes the final decision whether to approve it.
MHHS is a fundamental reform that will affect both existing and future participants in the energy market. The DWG therefore encourages views from all stakeholders.

Consultation on reducing CADL and DMAT parameters in 2018
We issued a consultation on the value of the pricing parameters De Minimis Acceptance Threshold (DMAT) and Continuous Acceptance Duration Limit (CADL). These parameters are used to classify and remove actions as part of the Imbalance Price Calculation.
We are proposing reducing CADL from 15 minute to 10 minutes and reducing DMAT from 1MWh to 0.1MWh.
- Elexon Insights: What’s the impact of changing DMAT and CADL?

If you have any views on views on the CADL and DMAT review, please respond using the consultation response form and send your responses, entitled “CADL / DMAT Review 2018”, to [email protected] by 17:00 on Friday 9 November 2018.
Consultation on how to align BSC reporting with EMR Regulations
The Schedule of EMR Settlement Data (which was agreed by Elexon, LCCC, ESC and EMRS in 2015) specifies that EMRS will be provided with a BM Unit Gross Demand Report, containing the gross demand data that EMRS requires in order to calculate the payments due from each licensed Supplier.
But, since then, Elexon has become aware of two evolutions:
- In July 2017, BEIS and Ofgem published their joint Smart Systems and Flexibility Plan. This plan makes clear that BEIS and Ofgem now interpret the definition of ‘supply’ in the Electricity Act as meaning that the Supplier Obligation is not payable in relation to supply to premises occupied by a generator licence holder for the purpose of carrying out activities authorised under the generation licence, even if the generation is not ‘Licensable’.
- Elexon has been approached by parties seeking to facilitate exempt supply (by the operators of community generation assets to local customers) under the class A supply licence exemption. Because this supply is not being made by a licensed Supplier it should not be subject to EMR charges, but currently the BM Unit Gross Demand Report sent to EMRS includes these volumes in the gross demand for the licensed Supplier who has registered metering on behalf of the exempt supplier.
The consultation document seeks views on how we should progress interim and enduring solutions to these issues. The BSC Panel will consider responses to the consultation at their meeting on 8 November 2018.
MIDS Review 2018 Consultation
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 to the MIDS timeband descriptions are recommended following BSC Modification P342, which decoupled the Submission Deadline for Energy Contract Volume Notifications (ECVNs) and Metered Volume Reallocation Notifications (MVRNs) from Gate Closure. BSC Modification P342 was implemented in November 2017.

Consultation for allocation of a new GSP to a GSP Group
Elexon has received a new GSP registration application from the Transmission Company.
Southern Electric Power Distribution (SEPD) is connecting two new circuits into the existing East Claydon 132kV substation. This new Systems Connection Point will be registered in Settlement as a new GSP, to be known as East Claydon – Southern GSP (ECLA_H).
The Transmission Company propose that GSP ECLA_H is allocated to the Southern (_H) GSP Group.
A diagram showing the proposed change is included in the consultation document.
