Workshop on Energy Statistics, China September 2012 Electricity and Heat Statistics 1
2 Introduction Overview of electricity in Canada Understanding the Canadian context Highlights of electricity data Electricity data collection: Capacity Electricity generation Co-generation and heat Consumption Collection issues and challenges
3 Electricity: the Canadian Context Canada is a major global producer of electricity Variety of generation methods across the country Canada also a large consumer Trade links are mostly north-south with USA
4 Map of Canada – electricity production

7 Issues faced by the electricity sector Aging infrastructure – security of supply Trade markets – stability, diversification New, emerging sources (wind, tidal, solar) Environmental concerns Deregulation of the marketplace – impact on prices
8 Electricity Statistics - Overview 6+ surveys Monthly, quarterly, annual Mail-out/mail-back Census surveys, above threshold Mandatory response Sources: direct from respondents, through administrative sources Cover capacity, generation, demand, finances
9 Measuring Capacity Annual electric power generating stations survey Covers utilities and companies with a generating capacity above 500 KW Frame based on input from provincial licensing boards, other surveys, industry research Objectives: to establish updated frame for other surveys; to monitor capacity utilization rates
10 Measuring Electricity Generation Monthly Electricity Survey: Volumes generated by utilities and industry Imports, exports, inter-provincial transactions Annual Electricity Supply and Disposition Survey: Volumes generated by utilities and industry Includes co-generation Co-generation and heat Variables included in other surveys But challenges and issues with quality
11 Measuring Electricity Consumption Industrial consumption of energy: Sample of establishments, by industry and geography Includes electricity consumption and generation Annual electricity supply and disposition: Track sales to consumers by sector Quarterly residential survey: Volumes & values sold by utilities to residential sector Proxy for residential consumption
12 Other Electricity Data Electric utilities financial reports (annual) Balance sheets: assets, liabilities, equity Report taxes, employees, wages, salaries, operating revenues and expenses To feed national accounts Electric Power Thermal Generating Station Fuel Consumption (annual) Quantity, cost, heat content of fuels consumed For electricity utilities and industry estimates
13 Ensuring Quality Follow up for partial or non-response Compare data for same respondent From same time period last year From other electricity surveys Balance inter-provincial transactions Compare with data from other sources Compare with other indicators to match trends
14 Collection Issues and Challenges Multiple surveys = respondent burden, conflicting data sets Deregulation of electricity markets makes it more difficult to track production to consumption Consumption data based on sellers, not users Will have to move to electronic collection Proliferation of small electricity producers
