Gemini Roadmap

The improvements we’re making to our Gemini System to facilitate the industry’s evolving capacity and balancing regimes.

The Gemini Roadmap will sustain and modernise the system’s core components

The Gemini System is a suite of online applications for managing the transportation of gas through the National Transmission System (NTS) in Great Britain.

Through the roadmap, we’re ensuring the system remains fit for purpose as we move to a ‘microservice’ solution and fully agile development.


What this involves

As part of this roadmap, we are:

  • reducing storage needs

  • automating code deployment, testing and processes

  • enhancing reporting and user experience


Customer benefits

  • £4m Service and Operate cost reduction.

  • £1.58m reduction in the required Regulatory Change budget for Gemini across the period.

  • Increased system availability from 99% to 99.9%.

  • Improved user experience driven by intuitive navigation, faster platform access and data flexibility via enhanced APIs.
