Gearing up for go-live of faster switching reforms

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.

Approval from Ofgem 

On 17 May, Ofgem approved P436 and Elexon is now working to have the changes ready for implementation at the same time as the CSS and REC 3.0. Ofgem will decide the exact day for this implementation, which it currently expects to be 18 July 2022.

What are the changes?

P436 will amend the Balancing and Settlement Code (BSC) itself and the BSC Code Subsidiary Documents to:

  • Set out the new relationship between the CSS and the Supplier Meter Registration Service (SMRS) provided by Licensed Distribution System Operators (LDSOs) under the BSC, in their capacity as Supplier Meter Registration Agents (SMRAs)
  • Transfer ownership of pre-existing SMRS provisions and data flows from the Master Registration Agreement (MRA) to the BSC. This will bring SMRS obligations (that haven’t been replaced with REC obligations due to the new CSS processes) under BSC governance, where previously they were split across the BSC and MRA.

Changes to the Elexon Kinnect Customer Solution

REC 3.0 also requires Elexon to provide the REC Code Manager with ongoing updates to electricity Market Participant Role information, for use in the CSS.

Elexon is progressing changes to its Kinnect Customer Solution system to automate provision of this data to the Retail Energy Code Company (RECCo). These changes affect the internal cloud system for the Customer Solution and not the user face that BSC Parties see and use to manage their BSC account.
