Half Hourly Settlement: Target Operating Model stakeholder day

The aim of this stakeholder event is to inform interested parties about the settlement design work undertaken to date, as well as introduce the TOM and discuss the development of a transitional approach.



We will present in detail the assumptions, methodology, and thought processes used in the development of the TOM, and there will be an opportunity for questions and comments from attendees.

Ofgem will also provide an update on their policy work on access to data for Half Hourly Settlement, Supplier Agent functions and development of the Business Case for MHHS.

Registering your interest

In its anticipated that this event will be very popular and space is limited. Therefore, we request that interested parties only register one attendee per organisation.

About the Target Operating Model

The Market-wide Half Hourly Settlement (MHHS) Design Working Group (DWG) has now identified its preferred Target Operating Model (TOM) which describes the end-to-end settlement process for MHHS. 

A report setting out the TOM will be provided to Ofgem and published on this website at the end of January. Following publication of the report, a consultation will take place.

Elexon is leading on the development of the Target Operating Model (Settlement Design) required to deliver Market-wide Half Hourly Settlement (MHHS). This is being delivered through the Design Working Group (DWG), made up of industry specialists, consumer representation, BEIS and Ofgem.

The work of the DWG forms a crucial element of Ofgem’s Significant Code Review (SCR) on Electricity Settlement Reform.

The DWG’s work for Stage 2 of the SCR is due to conclude at the end of August 2019, when the final TOM and transitional approach will be delivered to Ofgem.
