Gemini e-Training

Getting the Best from Gemini

Gemini is a system of online applications managed by us and used by Great Britain's gas industry to control the flow of gas through the network. The system is used for processes including:

  • Allocations
  • Measurement
  • Scheduling

The Gemini suite uses two different applications to operate, Gemini and Gemini Exit:

  • Gemini is used to put gas into the network
  • Gemini Exit is used to take gas out of the network

So that our customers can get the best from both Gemini and Gemini Exit, we provide learning materials, training opportunities and online guidance.
