UNC527: Implementation of Annual Quantity arrangements; UNC528V: Implementation of Supply Point Administration, gas allocation and settlement arrangements; UNC529: Implementation of Retrospective Adjustment arrangements (Project Nexus transitional mods)

Decision

Publication date

We have approved UNC527 and UNC528 and rejected UNC529 modifications to the Uniform Network Code (UNC).

UNC527 seeks to establish which meter reads submitted prior to the Project Nexus implementation date may qualify as being valid for the post-Nexus processes introduced by UNC432. UNC528V also seeks to provide an orderly transition from the current UNC rules to those introduced by UNC432 around gas demand estimation, allocation, settlement and reconciliation. UNC529 sets out arrangements for the orderly and efficient transition from current UNC arrangements to the revised business rules to be given effect with the implementation of UNC434.
