Historical Gas Flows
Short Term Trading Market
The Eastern Gas Pipeline is a facility operator and an allocation agent in the New South Wales short term trading market which commenced on 1st September 2010.
Transportation agreement for access to the Tasmanian Gas Pipeline
A prospective Tasmanian Gas Pipeline shipper must enter into a gas transportation agreement on the Eastern Gas Pipeline in order to transport their gas onto the start of the Tasmanian Gas Pipeline. A standard gas transportation agreement is available on request. Prior to entering into an Eastern Gas Pipeline gas transportation agreement shippers must be recommended by the Tasmanian Gas Pipeline.

Notes
- All values measured or specified at 15C and 101.325 kPa gauge unless otherwise stated
- Wobbe Index means the Higher Heating Value divided by the square root of the relative density of the gas, both measured at the same time
- For the purposes of this Eastern Gas Pipeline natural gas Specification, carbon dioxide and nitrogen will be deemed to be inert gases
