Unified Network Model (UNM)


What we will do and why

Alignment of the planning and operational network models to drive consistency of data across enterprise systems, and enable the exchange of data internally and externally using Common Information Model (CIM).

Key deliverables

  • Unified network data model covering all voltage levels through integration of data across relevant enterprise systems
  • Exchange of interoperable data in a Common Information Model (CIM) compliant form
  • Data quality enhancements

Target outcomes

  • Consistent provision of network and asset data.
  • Data interoperability.
  • Expedited access to reliable network and asset data.

Measures of success

  • Consistency of asset and network data.
  • Extent and data interoperability and integration.
  • Extent to which data is exchanged in alignment with peers and external stakeholder’s CIM requirements.

Stakeholder Engagement

We have actively engaged with a range of stakeholders to gather feedback and enhance our data exchange and interoperability efforts using CIM as the exchange mechanism. Our engagement included distributing surveys to internal and external stakeholders, including members of the International Utilities Working Group (IUWG). We partnered with Open Grid Systems to create a Proof of Concept (PoC) aimed at addressing stakeholder concerns and finding scalable solutions for data exchange challenges. We also conducted a dissemination event to share our PoC findings with internal stakeholders and circulated a summary report to solicit feedback. Furthermore, we published a CIM CGMES file for external stakeholders to review and sought feedback on its utility and accessibility. We have actively participated in sector-wide working groups and contributed to a discussion paper highlighting gaps in the CGMES profile concerning data exchange requirements for the Long Term Development Statement (LTDS) publication.

23.12.2023 Update

The description and outputs were adjusted to remove reference to a standalone platform, as the solution will now focus on integration of existing technology. More detailed milestones have also been added following a successful proof of concept which has informed planning. A stakeholder engagement section was also added.
