Explanatory Notes


Introduction

1 This publication presents estimates of energy consumption and electricity generation by selected Australian industries in 2017-18. The estimates are produced by directly collected data from the Energy, Water and Environment Survey (EWES), conducted by the Australian Bureau of Statistics (ABS).

Reference period

2 The period covered by the collection is, in general, the 12 months ended 30 June of the relevant year. Where businesses are unable to supply information on this basis, an accounting period for which data can be provided is used. As a result, the estimates can reflect trading conditions that prevailed in periods outside the twelve months ended June in the relevant year.

3 The data incorporates all business units in scope of the EWES that were in operation at any time during the year. They also include any temporarily inactive units, i.e. those units which were in the development stage or were not in operation, but still existed and held or acquired assets and liabilities and/or incurred some non-operating expenses (e.g. depreciation, administration costs).


Classifications

4 The businesses that contribute to the statistics in this release are classified:

  • by state and territory.
  • by business size.


Scope

5 The scope of the collection consisted of all business entities operating in the Australian economy during 2017-18 and classified to:
  • Division B Mining
  • Division C Manufacturing
  • Division D Electricity, gas, water and waste services
  • Division E Construction
  • Division I Transport, postal and warehousing

6 Government owned or controlled Public non-financial corporations were included.

7 Micro non-employing units were excluded from the survey.


Coverage

8 This section discusses frame, statistical units, coverage issues and improvements to coverage.

Frame

9 Businesses contributing to the estimates in this release are sourced from the ABS Business Register (ABSBR), which has two components as described below.

Statistical units

10 The ABS uses an economic statistics units model on the ABSBR to describe the characteristics of businesses and the structural relationships between related businesses. Within large and diverse business groups, the units model is used to define reporting units that can provide data to the ABS at suitable levels of detail.

11 The ABSBR sources its register information from the Australian Business Register (ABR) and uses a two population model. The two populations comprise what is called the Profiled Population and the Non-Profiled Population. The main distinction between businesses in the two populations relates to the complexity of the business structure and the degree of intervention required to reflect the business structure for statistical purposes.

Non-Profiled Population

12 The majority of businesses included on the ABSBR are in the Non-Profiled Population. Most of these businesses are understood to have simple structures. For these businesses, the ABS is able to use the Australian Business Number (ABN) as the basis for a statistical unit. One ABN equates to one statistical unit.

Profiled Population

13 For a small number of businesses, the ABN unit is not suitable for ABS economic statistics purposes and the ABS maintains its own units structure through direct contact with businesses. These businesses constitute the Profiled Population. This population consists typically of large or complex groups of businesses. The statistical units model below caters for such businesses:
  • Enterprise group: This is a unit covering all the operations in Australia of one or more legal entities under common ownership and/or control. It covers all the operations in Australia of legal entities which are related in terms of the current Corporations Law (as amended by the Corporations Legislation Amendment Act 1991), including legal entities such as companies, trusts and partnerships. Majority ownership is not required for control to be exercised.
  • Enterprise: The enterprise is an institutional unit comprising:
      • a single legal entity or business entity, or
      • more than one legal entity or business entity within the same enterprise group and in the same institutional subsector (i.e. they are all classified to a single SISCA subsector).
  • Type of activity unit (TAU): The TAU is comprised of one or more business entities, sub-entities or branches of a business entity within an enterprise group that can report production and employment data for similar economic activities. When a minimum set of data items is available, a TAU is created which covers all the operations within an industry subdivision (and the TAU is classified to the relevant subdivision of the ANZSIC). Where a business cannot supply adequate data for each industry, a TAU is formed which contains activity in more than one industry subdivision.

Coverage issues

14 The ANZSIC based industry statistics presented in this release were compiled differently from activity statistics. Each ABN unit or TAU on the ABSBR has been classified (by the ATO and the ABS respectively) to its single predominant industry class, irrespective of any diversity of activities undertaken.

15 Some businesses engage, to a significant extent, in activities which are normally carried out by different industries. For example, a predominantly mining business may also undertake significant amounts of manufacturing. Similarly, a mining business may produce significant volumes of goods which are normally produced in different mining industries. Where a business makes a significant economic contribution to industries classified to different ANZSIC subdivisions, the ABS includes the business in the Profiled Population, and 'splits' the TAU's reported data between the industries involved. Significance is determined using total income.

16 A TAU's reported data are split if the inclusion of data relating to the secondary activity, in the statistics of the industry of the primary activity, distorts (by overstating or understating) either the primary or secondary industry statistics at the ANZSIC subdivision level by:
  • 3% or more, where the industries of the primary and secondary activities are in the same ANZSIC division.
  • 2% or more, where the industries of the primary and secondary activities are in different ANZSIC divisions.

17 The ABS attempts to maintain a current understanding of the structure of the large, complex and diverse business groups that form the Profiled Population on the ABSBR through direct contact with those businesses. Resultant changes in their structures on the ABSBR can affect:
  • the availability of such businesses (or units within them) for inclusion in ABS collections.
  • the delineation of the units, within those groups, for which data are to be reported.

18 The ABS attempts to obtain data for those businesses selected for direct collection and which ceased operation during the year, but it is not possible to obtain data for all such businesses.

Improvements to coverage

19 Data in this release were adjusted to allow for lags in processing new businesses to the ABSBR, and the omission of some businesses from the register. The majority of businesses affected, and to which the adjustments apply, are small in size. As an example, the effect of these adjustments is generally 4% or less for most ANZSIC industry divisions.

20 Adjustments were made to include new businesses in the estimates for the period in which they commenced operation, rather than when they were processed to the ABSBR.

21 For more information on these adjustments, please refer to the ABS publication Information Paper: Improvements to ABS Economic Statistics, 1997 (cat. no. 1357.0).


Definition of key terms

22 Definitions for the data presented can be found in the Glossary.


Survey design

23 The frame (from which the direct collect sample was selected) was stratified using information held on the ABSBR. Businesses eligible for selection in the direct collect sample were then selected from the frame using stratified random sampling techniques.

24 Businesses were only eligible for selection in the survey (the direct collect sample) if their turnover exceeded a threshold level, or the business was identified as being an employing business (based on ATO information), as at the end of the reference period.

25 Businesses which met neither of these criteria are referred to as 'micro non-employing businesses'. These businesses were not eligible for selection in the sample.

26 A sample of 10,038 businesses was selected for the directly collected part of the 2017-18 EWES. Each business was asked to provide a range of key energy and water consumption and expenditure figures via an online survey questionnaire.


Effects of rounding

27 Where figures have been rounded, discrepancies may occur between totals and the sums of the component items. Proportions, ratios and other calculated figures shown in this release have been calculated using unrounded estimates and may be different from, but more accurate than, calculations based on the rounded estimates.


Data comparability

28 In some cases estimates in this release may differ from those collected from other sources. These differences may be the result of sampling or non-sampling error, or may result from differences in scope, coverage, definitions, data source or methodology.

29 Estimates on energy use and electricity generation have been produced since 2008-09 from the EWES. Given each iteration of the survey has a number of differences, such as changes to the scope, data source, form design and methodology, caution should be exercised when comparing estimates over time.


Energy Prices

30 This release does not support the calculation of an average unit price utilising the monetary estimates and physical estimates in this release. There is a broad range of price indexes published by the ABS for the purpose of measuring price change over time.


Revisions

31 A select number of revised estimates for the 2014-15 reference year have been included for download to provide users with updated information. For more information on these revised estimates, please refer to the Changes since 2014-15 in this issue.

Acknowledgement

38 ABS releases draw extensively on information provided freely by individuals, businesses, governments and other organisations. Their continued cooperation is very much appreciated; without it, the wide range of statistics published by the ABS would not be available. Information received by the ABS is treated in strict confidence as required by the Census and Statistics Act 1905.

Use of Australian Taxation Office (ATO) data in this publication

39 The results of these statistics are based, in part, on tax data supplied by the ATO to the ABS under the Income Tax Assessment Act 1936, which requires that such data are only used for statistical purposes. No individual information collected under the Census and Statistics Act 1905 is provided back to the ATO for administrative or regulatory purposes. Any discussion of data limitations or weaknesses is in the context of using the data for statistical purposes, and is not related to the ability of the data to support the ATO's core operational requirements.

Data confidentiality

40 Legislative requirements to ensure privacy and secrecy of these data have been followed. Only people authorised under the Australian Bureau of Statistics Act 1975 have been permitted to view data about any particular organisation and/or person in conducting these analyses. No information about individual taxpayers (persons) has been released to the ABS. Aggregated personal income tax data are confidentialised by the ATO before release to the ABS. In accordance with the Census and Statistics Act 1905, results have been confidentialised to ensure that they are not likely to enable identification of a particular person or organisation.
