P413 Assessment Procedure Consultation


Who will this impact?

We have issued P413 ‘Enable Elexon to be the Programme Manager for the implementation of Market-wide Half Hourly Settlement’ for Assessment Procedure Consultation, which you are invited to respond to by 15 January 2021 .

P413 will require Elexon to provide Market-wide Half Hourly Settlement (MHHS) Implementation Management services under the BSC, as the BSC Company (BSCCo), where Ofgem determines that Elexon shall provide some or all of these services. These services may include activities and responsibilities relating to MHHS programme management, system integration and programme party co-ordination (or any part of these). Elexon may also appoint a MHHS Implementation Assurance Provider, depending on Ofgem’s preference.

Under the Proposed Modification, Elexon’s costs in providing MHHS Implementation Management services will be recovered from BSC Trading Parties by market share (through the BSC’s existing Main Funding Share mechanism). The Workgroup also seeks views on a potential Alternative Modification that would recover these costs solely from Suppliers by market share (through a new Specified BSC Charge).

P413 will enable Elexon to participate in any competitive tender exercise used to appoint MHHS Implementation Management services. Any Elexon bid costs will be recovered from BSC Trading Parties through the Main Funding Share, but will be subject to a cap.
