This Change Proposal has been raised to deliver the requirements outlined in Modification 0819 Establishing/Amending a Gas Vacant Site Process.

Modification 0819 aims to create a new process for Vacant Product Class 4 Non-Daily Metered (NDM) sites which would allow Shippers to receive commodity and performance relief (immediately) and capacity relief (after 12 months at vacant status) for sites in their ownership.

A SMP must meet the Vacant Site criteria outlined in Modification 0819 and associated guidance documentation for the Shipper to have the ability to effectively manage their Settlement Performance Obligations and Transportation Costs.

Impacted Customer Types

  • Shipper
  • DNO
