What is being bought

Published requirement description

Please respond by 18.30 1st May 2026

Request for Information (RFI)

National Grid Electricity Transmission (NGET) is developing a Digital Twin for Electrical Power systems to support transmission network design, analysis, planning, operations, and asset lifecycle management.

A critical enabler of this vision is a Network Master Model Manager: a controlled, authoritative environment used to create, govern, validate, and distribute trusted network model data (including associated metadata) across multiple engineering and operational tools.

Through the RFI, National Grid is seeking information on how your solution supports:

Robust model governance and lifecycle management

Standards based interoperability (e.g. CIM / CGMES)

Strong data quality controls and auditability

Secure deployment and operation at national infrastructure scale

Integration with existing planning, operations, and data platforms

Documentation outlining a request for information (RFI) will be provided to interested suppliers. Please contact Baljinder.besra@nationalgrid.com if you would like to receive the RFI documents and if you wish to submit a response.

This RFI does not constitute a formal competitive tendering process.

Should National Grid have a desire towards supplier selection and contract award, suppliers may be invited to the possible stages of pre-qualification and Request for Proposal.

Further stages are optional for National Grid.

National Grid is at the heart of a rapidly evolving energy system.

Our business units play a vital role in connecting millions of people to the energy they depend on, while continuously seeking ways to make the system cleaner and more sustainable.

About this data
  • Source. Official UK public procurement notices (Find a Tender), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly.
  • Two views, kept apart. The authority’s own track record and the wider market for the same kind of work sit side by side and are never mixed. Where the local picture is too thin, a figure widens to a broader market and says which one it used.
  • Forecasts are labelled. The price forecast and its range, possible competitors and the earlier-work matches are our estimates from past awards: not published facts, not win chances and not price advice. Official notices do not say who is bidding.
  • Every figure shows what it rests on. Not every notice publishes a bid count, a value or a delivery region, so each figure carries the number of records behind it, and one built on few records is marked as such. The on a figure explains it; the counting rules are in the methodology. Spotted something wrong? Tell us.
