Podcast: MHHS is live - Are we ready for what's next? With Elexon's Helen Adey

MHHS Energy Transformation

We've released the second episode of our Expert Interview series, exploring the shift from MHHS delivery milestones to the long-term operational reality of a new settlement world.

Kevin Scott and Jon Vincent are joined by Helen Adey, Director of Settlement Services at Elexon, to go behind the scenes of the programme. The discussion moves beyond technical "go-live" dates to examine how industry-owned reform is playing out on the ground, and what it actually takes to operate effectively when settlement windows are compressed from 14 months to just four.
 

Watch the full conversation to explore:

  • The Reality of Industry Ownership: Reflections on MHHS as a test case for industry-led reform and how the balance between facilitation and enforcement is evolving
  • Operating at Scale: Why our analysis shows 60% of core supplier processes are impacted by MHHS, and how to bridge the gap between "technical readiness" and "operational resilience"
  • Milestones vs. Outcomes: The changes in focus areas as MHHS progresses, from programme milestones to migration volumes, settlement timelines, and the ability to manage continuous data flows
  • From Data to Commercial Value: How the move to half-hourly data could influence how suppliers approach products, customer insight and value creation

  • The Readiness Gap: Moving from periodic reconciliation to a continuous data environment, and why clarity on data ownership is critical when working across multiple providers
  • Unlocking Value: How to translate complex, granular usage data into practical benefits for customers that remain easy to navigate
  • Long-term Resilience: Practical steps for ensuring your operating model is robust enough to handle the increased pace of the new market
