Elexon is helping the industry to get set for the go-live of the Central Switching Service (CSS) this summer as part of Ofgem’s Switching Programme.

The CSS, which will be governed by version 3.0 of the Retail Energy Code (REC), will provide a single, dual fuel switching process for gas and electricity. The aim is to make switching faster and more reliable.

On 12 May, we issued BSC Circular EL03581, which gave notice to BSC Parties that the ‘Coronavirus Disapplication Period’ for Supplier Charges will be ending. This means that, from September 2022, Supplier Charges for SP08 will be reapplied from the September Performance Assurance Reporting and Monitoring System (PARMS) Reporting Period.

In the past eight years, we have identified five Grid Supply Point (GSP) Metering errors, equal to around 1.4% of the total number of GSP Meters. These errors have caused energy to be recorded incorrectly. As any unaccounted energy is allocated to BSC Parties through GSP Group Correction and Transmission Losses, such metering errors can present a large impact on the allocation of energy and therefore the accuracy of Trading Charges to BSC Parties.

We are publishing a beta version of our GSP change-point detection model to gather feedback from participants and help us identify other areas where central analytics and reporting could support industry in mitigating risks to Settlement.

Elexon has been investigating errors in Settlement related to two Grid Supply Point (GSP) Groups: South Eastern GSP Group (Group _J); and London GSP Group (Group _C). This follows our continued monitoring of the Annual Demand Ratio (ADR).

We are delighted that today, 9 May, Ofgem confirmed its decision to appoint Elexon as the independent Capacity Market Advisory Group (CMAG) secretariat, subject to a BSC Modification being raised and approved to enable us to do the work.

Elexon will be joining forces with industry not-for-profit Icebreaker One as part of their government-supported Open Energy programme, which seeks to revolutionise the way data is shared across the energy sector to make sure the UK achieves its Net Zero goals. 

On 30 June 2022, Elexon will implement Modification P375 ‘Settlement of Secondary BM Units using metering behind the site Boundary Point‘.  This is a major change to the Wholesale Electricity Trading Arrangements, which supports Net Zero by creating more opportunities for smaller asset owners to provide balancing services.  

Centrica is due to begin a trial this September where controllable storage heaters will provide demand-side response (DSR) when needed, by dialling down their demand. 

It is the second trial which has been approved by Ofgem to use Elexon’s Balancing and Settlement Code (BSC) Sandbox. The Sandbox allows innovators to trial concepts in a live market environment without having to meet all the usual BSC rules.

Yesterday (21 April) Ofgem confirmed that the Balancing and Settlement Code will be used to govern and fund the new Data Integration Platform (DIP) to support Market-wide Half Hourly Settlement (MHHS). This means that Elexon will manage the DIP service provider, which is currently being procured through the MHHS Programme.

Today the Department for Energy Department for Business, Energy and Industrial Strategy (BEIS) and Ofgem jointly responded to the consultations they published in July 2021 on a Future System Operator (FSO), and reforming the energy codes.  National Grid ESO will move away from National Grid plc and become an independent, publicly owned FSO.

As part of that process there will also be a consultation on the ownership of Elexon, which is currently owned by National Grid ESO.
