Guide to Pipeline Flow Directions

This table shows the default flow direction for pipelines on the Bulletin Board. 

Where gas flows are reported on the Bulletin Board there are currently two methods of indicating the direction of flow:

1. Reporting a net number as either positive or negative depending on the direction. 

Before 6 October 2016 both Actual Flow and Forecast Pipeline Flows were reported using this method, currently only Forecast Pipeline Flows are reported in this way. The table below denotes which direction is considered positive on each pipeline. In order to interpret Forecast Pipeline Flow data, or Actual Flow data from before 6 October 2016, users would need to refer to this table. 

All Actual Flow data from before 6 October 2016 was moved into the delivery column of the new Actual Flow report. When interpreting this data, especially for the Wallumbilla and Moomba demand zones, the key indicator for pipeline flow direction is the direction identified in this table.

2. Reporting Receipts and Deliveries separately.

As of 6 October 2016 Actual Flow data are reported separately as receipts or deliveries, which are defined from the perspective of the reporting facility.

Receipt:

The receipt of natural gas from a demand zone, a production zone, another BB facility, or a Connection Point into a BB facility. A pipeline reports a receipt when gas is injected into it.

Delivery:

The delivery of natural gas from a BB facility to a demand zone, a production zone, another BB facility or a Connection Point. A pipeline reports a delivery when gas flows out of the pipeline.
