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

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

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
