MHHS Programme Governance Framework Consultation

Thank you to everyone who responded to the MHHS Programme Governance Framework Consultation, which is now closed. We received 16 consultation responses from a broad spectrum of the energy industry and we are delighted to see so many Programme Participants engaging with the MHHS Programme.

These responses have helped us be assured that the proposed governance framework and constituency model is ready to be taken to PSG for approval. It has also confirmed key areas such as clarity on the decision-making criteria and the requirement to provide greater lower level governance and meeting clarity is required.

Following the recent Market-wide Half-Hourly Settlement (MHHS) request for constituency representative nominations for the Level 2 and Level 3 Programme governance groups, we are pleased to confirm the elected nominees. Click here to view the full list of nominees for the respective Groups . These include membership for the following:

  • • Programme Steering Group (PSG)
  • • Implementation Advisory Group (IAG)
  • • Design Advisory Group (DAG)
  • • Cross-Code Advisory Group (CCDG)

The first governance meetings are scheduled for November and we have reached out to all nominees with proposed meeting dates. The initial meetings will be a ‘meet and greet’, and to give everyone the opportunity for introductions, and to ensure representatives understand their roles and responsibilities within the groups. We will also provide a Programme update. The meeting dates will be published on our website shortly.

For more information about the Programme decision groups, please see the MHHS Programme Governance Framework document.

As part of the Market-wide Half-Hourly Settlement (MHHS) Governance Framework we are creating a number of Level 4 Industry Working Groups to build on the work already carried out within the Code Change Development Group (CCDG) and the Architecture Working Group (AWG) to deliver the MHHS design.

Thank you to everyone who has volunteered to join the Market-wide Half-Hourly Settlement (MHHS) Level 4 Working Groups. The first Business Process and Requirements Working Group (BPRWG) and Technical Design Working Group (TDWG) meetings will take place on 3 and 4 November respectively. These will be introductory sessions to provide background to the MHHS design activity and set the scene for how the Working Groups and sub-groups will work. Following the initial BPRWG meeting, we will start to work through the detail of the design in the Registration and Smart Market Segment sub-groups.

The diagram on the left demonstrates the structure of these groups, and more specific information on the BPRWG and TDWG responsibilities.

Both Working Group meetings will be held monthly, and are expected to be all day sessions to review design artefacts for recommendation to the DAG. We request that Working Group members allocate up to half a day a week to contribute to discussing and resolving issues to enable the MHHS Design team to develop the required design artefacts.

We are continuing to engage with Industry to set up the Level 4 Working Groups and there is still time if you are interested in joining the Working Groups. The groups are open to everyone and are a great opportunity to input into the end to end design for MHHS. We are particularly looking for more representation from small and medium suppliers (or their IT Service providers) to make sure we have full coverage.

If you are interested in joining or would like more information, please get in touch with us at [email protected].

High Level Governance Structure

The Lead Delivery Partner (LDP) is required to deliver four key service roles:

1. Central Programme Team (CPT)

2. Programme Management Office (PMO)

3. Programme Party Coordinator (PPC)

4. Systems Integrator (SI)

An industry-led governance model will ensure the decision making between the SRO, Implementation Manager (IM) and MHHS Programme participants is appropriately balanced. The model will ensure that the SRO is empowered to make decisions on behalf of the industry, but is accountable to, and has engaged and consulted with MHHS Programme participants.
