The Electric Utility Construction Price Index (EUCPI) series measures the price change for constructing two types of plants, distribution systems and transmission lines systems, representing electric utility capital expenditure construction projects.
Data release - September 7, 2000
Description
The Electric Utility Construction Price Index (EUCPI) series measures the price change for constructing two types of plants, distribution systems and transmission lines systems, representing electric utility capital expenditure construction projects. The EUCPI is used by the Canadian System of National Accounts for the deflation of gross expenditures on related construction projects. The EUCPI also provides the user with information that can be employed in contract escalation, cost-benefit analysis, benchmarking studies and time series analysis.
Reference period: The time period for which the EUCPI equals 100; currently this is the year 1992.
Collection period: The data are collected during the first four months of the year following the reference period.
Subjects
- Construction
- Construction price indexes
- Non-residential building construction
- Prices and price indexes
Data sources and methodology
Target population
The universe for the EUCPI consists of material and equipment suppliers and manufacturers, and construction companies who are active in the construction of electric utility capital expenditure construction projects.
Sampling
This is a sample survey with a cross-sectional design.
Error detection
All responses are checked by the commodity specialists and incorrect or suspicious data is verified with the respondent.
Estimation
Weights
The weights are derived from information relating to completed construction projects, as supplied to Statistics Canada by the various electric utilities across Canada. From this information, a representative model is produced and the corresponding weights are used to aggregate the sub-component series into the total series.
Prices
Prices are collected for three general categories of inputs; materials and equipment , labour and finance costs. The prices provided by respondents for materials and equipment represent the price of supplying these items and where applicable, installing them. Other price series related to materials and equipment come from the Statistics Canada Industrial Product Price Index (IPPI) and Non-residential Building Construction Price Index series, and the U.S. Bureau of Labour Statistics (BLS) producer price index series. Data on labour costs comes from the Statistics Canada Survey of Employment, Payrolls and Hours (SEPH) and the Construction Union Wage Rate Index (CUWR) series. The information pertaining to finance costs is obtained from the Bank of Canada.
Disclosure control
Statistics Canada is prohibited by law from releasing any information it collects which 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.
Collected data are converted to price indexes and data are released as such, so that it is not possible to identify the suppliers of raw prices.
Revisions and seasonal adjustment
The EUCPI is revised one year after release.
Data accuracy
The statistical accuracy of this index depends on price and weight data. Price data are obtained from several sources including a sample survey, other price index series (IPPI and BLS) and labour cost series (CUWR and SEPH), while the weight data are obtained from the electric utilities across Canada. Both kinds of input data are subject therefore to their own errors. For the quality of the surveyed price data, the response rate is high (approximately 85%) and there is little imputation and editing required. Consequently, the aggregate indices at the all levels are considered to be statistically reliable.
Though the EUCPI uses a sample survey methodology to obtain a portion of the necessary information, confidence intervals are not currently estimated. Indexes for higher and lower levels of aggregation are considered to be statistically reliable.
