About the PSG

The PSG is a senior-level group, chaired by Chris Welby, and formed of individuals appointed to represent their constituencies. The skill sets of members ranges from programme delivery through to governance.

This Steering Group is the overarching Programme decision-making authority for Market-wide Half-Hourly Settlement. PSG members will discuss key issues and challenges and will make strategic decisions to efficiently drive the MHHS Programme forward, within the plan timescales.

The PSG will ensure appropriate representation of different Programme participants, to enable transparency for all impacted constituency groups and stakeholders involved in the Programme. The PSG will receive escalations from lower level Working Groups, or delegate decision-making to appropriate lower level groups as required.


The PSG and other decision-making groups are made up of a mix of participants from across the industry. Click here to view the membership for all the Steering and Advisory Groups.
