Detailed information for fourth quarter 2002

Status:

Inactive

Frequency:

Quarterly

Record number:

2166

The survey provides estimates of the energy consumption of the energy-intensive manufacturing industries in Canada.

Data release - October 2, 2003

Description

This survey was discontinued after the fourth quarter of 2002 reference period. The data are still collected annually through the Annual Industrial Consumption of Energy Survey (record number 5047).
______________________________________

The survey provides estimates of the energy consumption of the energy-intensive manufacturing industries in Canada. It is funded by Natural Resources Canada and Environment Canada. The information from this quarterly survey complements the information collected from a sample of less energy-intensive industries in the Annual Industrial Consumption of Energy Survey (record number 5047).

Federal (Natural Resources Canada, Environment Canada) and provincial agencies are provided with data on a regular basis, as are several forest products associations.

Reference period: Quarter

Collection period: The data are collected within 2 months after the reference quarter.

Subjects

  • Energy
  • Energy consumption and disposition

Data sources and methodology

Target population

The target population is all major energy consuming industries (pulp and paper, iron and steel, smelting and refining, cement plants, oil refineries, chemicals, and mining), all large utility steam plants, establishments using 1,000 Mg or more of coal per year, and all other manufacturing establishments that are large consumers of energy within each province or territory.

The survey frame is developed from the Annual Survey of Manufactures (Survey ID 2103) for manufacturing industries, the Census of Mines, Quarries and Sand Pits (Natural Resources Canada) for the mining industries, and the Electric Power Generating Stations survey (Survey ID 2193) for the electric utility conventional steam generating stations.

Instrument design

The questionnaire comprises energy inventories and the consumption of coal, coal coke, petroleum coke, heavy fuel oil, refinery fuel gas, natural gas, middle distillates, electricity, wood, spent pulping liquor, steam, propane, refuse and steam sales. The energy uses covered are consumption as fuel, consumption to produce steam for sale, consumption in production of electricity, and consumption for non-fuel use.

The questionnaire is respondent completed.

Specialized questionnaires are used to collect data for the following NAICS (North American Industrial Classification System) industries: the petroleum products industry (NAICS 324110, 211114), the other primary steel industries (NAICS 331110), the pulp and paper industry (NAICS 3221, 321216), industrial chemical, plastic and synthetic resin industries (NAICS 3251, 3252 and 3253), and electric power thermal generating stations (NAICS 221112).

The questionnaires are periodically revised based on contacts with respondents and data users.

Sampling

This survey is a census with a cross-sectional design.

This methodology does not apply.

Data sources

Responding to this survey is mandatory.

Data are collected directly from survey respondents.

The data are collected by Statistics Canada's Head Office through a mail-out mail-back process. Follow-ups are conducted by phone or fax as needed to reach the target response rate.

Each year, respondents are sent the "Industrial Consumption of Energy Survey Guide."

Error detection

The following methods of error detection are used:

- Edits are performed during capture to ensure that keying errors are corrected. Other consistency edits are also done on each questionnaire once data capture is complete to ensure that related data values are consistent with each other.

- Data are checked against the types and volumes of fuels consumed by the establishment in previous periods.

- Data are compared with estimates from the Annual Survey of Manufactures and the Electric Power Thermal Generating Stations Fuel Consumption survey (Survey ID 2196).

- Statistical editing compares reported values to a distribution of data values. If the reported values are at either extreme end of the distribution, the respondent who reports such data fails the edit and becomes a candidate for possible follow-up.

- Any edit failures not resolved are flagged in order to be excluded from use in imputation.

Imputation

The response rate for the survey is over 90%. Statistical imputation is used for cases of total non-response. A trend factor is calculated for industry groupings and applied to the last period's response for respondents with missing data in that grouping to obtain an imputed response for the current period.

Quality evaluation

Fuel consumption estimates are compared with those from the Annual Survey of Manufactures and with energy surveys such as the Electric Power Thermal Generating Stations Fuel Consumption survey.

Disclosure control

Statistics Canada is prohibited by law from releasing any information it collects that could identify any person, business, or organization, unless consent has been given by the respondent or as permitted by the Statistics Act. Various confidentiality rules are applied to all data that are released or published to prevent the publication or disclosure of any information deemed confidential. If necessary, data are suppressed to prevent direct or residual disclosure of identifiable data.

In order to prevent any data disclosure, confidentiality analysis is done using the Statistics Canada Generalized Disclosure Control System (G-Confid). G-Confid is used for primary suppression (direct disclosure) as well as for secondary suppression (residual disclosure). Direct disclosure occurs when the value in a tabulation cell is composed of or dominated by few enterprises while residual disclosure occurs when confidential information can be derived indirectly by piecing together information from different sources or data series.

Data accuracy

The response rate to the survey is over 90%.

The survey is a census of the target population for selected NAICS industries; thus, under-coverage is minimal for these industries.
