About the HH Settlement Workshop

The majority of P272 sites have been transferred to HH Measurement Classes E, F, and G, and in recognition of this Elexon is hosting a Workshop to inform and prepare Parties for issues that may arise in HH Settlement.

The implementation of P346 and P347 have removed barriers preventing Suppliers moving toward EHHS. In order to support Suppliers, Elexon will facilitate the troubleshooting of common issues inclusive of Communications Faults and Fault resolution timescales

Elexon will walk through the Settlement Risks associated to EHHS. Providing information on the Root Causes, BSC Controls, and Parties responsibilities, prior to the workshop please find information on the Risk Evaluation Register and the Risk Operating Plan.

Agenda item five was previously going to be on Half Hourly Elective Settlement. Instead we will now present on the development of the approach for Market-wide Half Hourly Settlement, as set out in by the Design Working Group (DWG) in its Target Operating Model (TOM).

The DWG consulted on the preferred TOM in February. This work forms a crucial element of Ofgem’s Significant Code Review (SCR) on Electricity Settlement Reform.

We will present in detail the development of the approach for each market segment and the critical path proposed by the DWG. There will be an opportunity for questions and comments from attendees.

For further details on the DWG’s work please visit the Design Working Group page of our website.
