Transporters in discussion with Correla have agreed on the below option to meet the CV validation rule challenge.
Option 3 - Create a specific CV Tolerance Range for the new meters for the relevant file types
This solution would involve each new hydrogen meter having a specific range not linked to the meter type.
The implementation of H100 is currently scheduled for June 2024.
Gemini Sustain Plus
In order to provide the decision makers with enough relevant information, the solutions assessed in the Design phase need to take into consideration the on-going Gemini Sustain Plus programme (XRN5564).
Please can all the following delivery options be costed and associated risks be provided as part of the BER process.
1) Delivery into Legacy Gemini – before Service Extraction of the relevant microservices have taken place.
2) Delivery into Legacy Gemini and new Gemini post Service Extraction of the relevant microservices
3) Delivery only into the updated Gemini platform. This solution will also need to consider an off-line interim solution (between June 2024 and September 2024)
