Half Hourly Settlement consultation stakeholder event

Elexon is leading on the design of the Target Operating Model (TOM) to deliver market-wide Half Hourly Settlement. We are doing this through the Design Working Group (DWG), made up of industry specialists with consumer representation, BEIS and Ofgem. This work forms a crucial element of Ofgem’s Significant Code Review (SCR) on Electricity Settlement Reform.

The DWG has developed five draft Target Operating Models (TOMs) which describe options for the end-to-end Settlement process for Half Hourly Settlement. Following engagement with the Design Advisory Board (DAB) and recommendation from the TOM Board the five TOMs have been approved by Ofgem’s Senior Responsible Officer (SRO) to be taken on to consultation with stakeholders in May 2018.

The aim of the event is to inform a wider audience of the Skeleton TOMs designs and principles. Elexon will present the work of the DWG, an evaluation of the TOMs against Ofgem’s design principles and an initial assessment of the individual TOMs. Our intent is to provide any additional detail that stakeholders may require before responding to the DWG consultation. There will be an opportunity for questions and comments from the audience.


Ofgem will provide an update on their policy work on Data Privacy, Agent Functions and the Business Case for Half Hourly Settlement.

White paper: Enabling customers to buy power from multiple providers – session added

We will devote part of the afternoon to present our White paper: Enabling customers to buy power from multiple providers. This white paper offers an Elexon view of how BSC central services could be adapted to offer Settlement solutions in support of individual customers buying electricity from more than one Supplier. We believe that relatively straightforward amendments to BSC central services, building upon the changes we will be delivering in 2019 to open the Balancing Mechanism to independent aggregators, could form the basis of new industry arrangements that allow customers the flexibility to buy electricity from multiple providers.

This is an opportunity for participants to ask questions to the white paper author, Elexon Senior Market Advisor Jon Spence, who will be presenting the paper.

It is anticipated that this event will be popular and spaces are limited. Therefore we request that interested parties only register one attendee per organisation.
