National Gas Transmission has announced it is to withdraw from providing the Distribution Network Operators (DNs) with the daily LDZ Flow-Weighted Average CV calculation (FWACV) service.
As a consequence, the DNs will become responsible for calculating their own daily LDZ FWACVs and, publishing the information to Shippers.
The associated 0719R Workgroup has assessed several options that might support the DNs in meeting their FWACV calculation/information provision obligations. The DNs have agreed that Xoserve should take the FWACV calculation role over in its entirety from National Gas Transmission. As such, the DNs have requested Xoserve to assess and develop a single option solution.
The DNs will re-route their existing ‘FWACV’ data flows from National Gas Transmission to Xoserve.
