Gas supply estimates provided for:
Estimates are presented of the key economic, financial and physical measures associated with the supply of electricity and gas to the Australian economy. For the year 2007-08 the physical measures of electricity supply and gas supply are illustrated by way of a supply chain diagram. The estimates provide an 'alternative' view of electricity supply and gas supply within Australia.
Estimates are provided for each electricity supply and gas supply business activity. Electricity supply activities are defined to comprise electricity generation, electricity transmission, electricity distribution, electricity wholesaling and retailing activities. Gas supply activities are defined to include gas extraction, gas pipeline transportation, and gas distribution (which includes gas wholesaling and gas retailing activities).
The alternative view ANZSIC coverage is shown in Table 1.1.
It is important to note that this alternative view is presented not to address any flaw in the ANZSIC 2006 classification system, but rather to provide users with further insight into electricity and gas supply activities - as such it is intended to supplement ANZSIC 2006 industry statistics.
The incorporation of gas extraction activity and gas transport activity into the alternative gas supply view effectively increases the size of Gas Supply relative to the industry view. This is the result of reclassification of relevant ANZSIC 2006 classes and not an extension of ANZSIC 2006 class boundaries. Technical Note 2 discusses the concept of an alternate view, and Technical Note 3 the methodology used in this publication.
While alternative view estimates are subject to the limitation that they cannot be compared on a 'like basis' with existing industry statistics they can, nevertheless, provide useful analytical insight to a segment of the economy of interest (such as electricity and gas supply).
The data source used to produce the alternative view estimates was Australian Industry, 2007-08 (cat. no. 8155.0)(see both the publication, and the attached data cubes, which contain the data from the 2007-08
Energy Supply Survey).
