Webinar on Market-wide Half Hourly Settlement Programme Budget

We are hosting a webinar tomorrow (10 June) on our proposed budget for the Market-wide Half Hourly Settlement (MHHS) Programme.

As part of its decision in April 2021 to implement MHHS, Ofgem appointed Elexon as the Senior Responsible Owner (SRO) and Programme Manager (PM) for MHHS.

We are asking for feedback on the budget document by 08:00 on Monday 14 June 2021.

About the webinar and how to register for it

The webinar is your opportunity to ask us questions about the budget, or the MHHS implementation programme.

The webinar takes place this Thursday, 10 June, from 14:00 to 14:45.

To register please visit our gotowebinar page.

Working alongside industry to deliver Market-wide Half Hourly Settlement 

We are pleased to be working with industry to deliver the SRO and PM roles, which involve co-ordinating the development, testing, integration and transition activities of around 180 organisations across the energy sector.  

Alongside its implementation decision, Ofgem also approved Balancing and Settlement Code (BSC) Modification P413 (alternative proposal), which will result in Suppliers funding the MHHS programme via an increase in Elexon’s costs.

Feedback on four key areas for the implementation programme

In the MHHS Programme Budget document  we are asking for feedback from the industry on four key areas that will help us to deliver MHHS implementation:

  • The MHHS Programme budget, which totals £90m over the 4.5 year implementation programme from 2021 to 2025. This  is consistent with Ofgem’s estimated budget for delivering the programme in its MHHS Full Business Case.  The budget for 2021/22 is £14.5m. 
  • The objectives and governance principles for the implementation programme (which include delivering the MHHS Target Operating Model on time, and cost effectively)
  • The Programme Management structure, which will see industry work groups collaborating with Elexon, and an independent body (procured by Ofgem) to provide assurance as the implementation programme progresses. Elexon will also ensure separation of MHHS SRO and programme management activities from the rest of its work in managing the BSC
  • A request for secondees from energy companies to work within Elexon’s Design Authority to help deliver the programme. We would expect secondments to last for periods of four to six months at a time.

Amending our Business Plans going forward

The BSC formally requires that Elexon notifies the industry of any proposed within-year changes to its Business Plan and associated budget, to allow BSC Parties to comment.

We are proposing that our 2021/22 BSC Business Plan is amended by including new sections on  MHHS programme implementation, and the associated MHHS programme implementation budget.

We intend to include in our main business plan document a section on the MHHS programme for the subsequent years (during the implementation of MHHS).
