National Grid has advised the DNs that from Q1 2022, it will withdraw its ‘Daily LDZ CV (FWACV)’ Service. Xoserve will be taking over the service in its entirety from National Grid.
Within the existing NG/DNs FWACV processes, there are several combined data flows that contain data that is (or will not be) required to calculate the FWACV.
Please provide an HLSO to include costs and delivery timescales for the following:
National Grid will continue to submit the PRCMS file into Gemini for all those data items other than the FWACV data.
Please consider the systems’ impact of not providing the FWACV data within this file e.g. file/data validation, dependency of other processes on FWACV data e.g. timing of associated batch jobs, Gemini processes
This change needs to be progressed in conjunction with the FWACV project, as ultimately it will need to be delivered at the same time as the project for the FWACV data to be processed by Gemini by the new channel from the DN’s.
To be clear the data items on the PRCMS that are being referred to are below;
- OF meter types
- OS meter types
- CV data field
In addition to this, National Grid would also like to understand the system impacts to removing the following data items from the PRCMS
- Stock Change (SC meter type)
- Embedded LDZ unique sites (US – Meter type)
The processing of these meter types will be picked up in a separate CR.
