The introduction of MHHS will see all electricity settlement moving to half-hourly data, enabling more accurate and granular measurement of energy consumption across the market.
This change is designed to improve settlement accuracy, enhance data quality, and support a more flexible and efficient energy system. For organisations, it will also bring increased visibility of energy usage and create new opportunities to better manage consumption and costs.
However, the scale of change means that organisations should begin preparing now to understand how MHHS will impact their operations, data processes, and supplier arrangements.

Supplier migration timeline: An outline of key industry milestones and migration phases, and what organisations should be aware of at each stage.
Challenges and risks: An honest assessment of expected challenges, including data readiness, supplier capability, and operational considerations.
What to look out for: Practical guidance on key indicators, dependencies, and potential risks during the transition period.
Post-migration benefits: An overview of the long-term benefits of MHHS, including improved accuracy, enhanced reporting, and greater energy insight.
