The UK government and Ofgem jointly published the energy digitalisation framework on March 23, 2026. The document sets out a vision for a coordinated and connected energy system across England, Scotland and Wales.

The framework delivers a commitment set out in the clean flexibility roadmap. It establishes a data domain model that groups digitalisation activity into four functional domains, each with clear responsibilities.

Context

Digitalisation has become a central thread in Great Britain's grid policy, sitting alongside flexibility, smart metering and network reform. Ofgem and the government have repeatedly flagged that disjointed data standards across transmission, distribution and consumer-facing systems raise integration costs for distributed energy resources and slow the connection of new generation and demand. The data domain model published on March 23 is intended to simplify that landscape.

By attaching the framework to the clean flexibility roadmap, the publication links data architecture work directly to the regulatory programme on demand-side response, storage and consumer flexibility. The territorial scope covers Great Britain rather than the whole United Kingdom, with Northern Ireland's electricity system regulated separately.

The framework itself is a policy paper rather than a binding rulebook. Implementation will depend on follow-on work by Ofgem, the National Energy System Operator, network licensees and code bodies, which will need to translate the four-domain structure into licence conditions, code changes and data-sharing obligations.
