Presentation Transcript

    1. 1 Combining Electric Power Surveys: The EIA-923 Robert H. Rutchik Energy Information Administration Meeting of the American Statistical Association (ASA) Committee on Energy Statistics April 19, 2007 This is a working document prepared by the Energy Information Administration (EIA) in order to solicit advice and comment on statistical matters from the American Statistical Association Committee on Energy Statistics. This topic will be discussed at EIA’s spring 2007 meeting with the Committee to be held April 19 and 20 2007.

    2. 2 Purposes of Presentation Illustrate how EIA combined four surveys with different: Respondent populations Data reporting levels – e.g., plant level, boiler level Data Due dates Solicit Committee advice on: Planning a cognitive and a field test Notifying respondents on what they need to do to respond

    3. 3 Current Respondent Populations

    4. 4 New Data in the EIA-923

    5. 5 EIA-923 Schedules and Data Reporting Levels

    6. 6 Current and EIA-923 Due Dates

    7. 7 EIA-923 Cognitive and Field Test in Limited Time Pick a random sample and send survey to whoever is selected Construct a stratified sample Two strata: Steam turbines 10 MW greater All other turbines Four strata: Steam turbines 10 MW greater monthly respondents Steam turbines 10 MW greater annual respondents All other plants monthly All other plants annual Separate out combined heat and power plants Other stratifications

    8. 8 Notifying Respondents One respondent receives complete survey No respondent, though, will fill in every schedule How do we notify respondents about what schedules they will complete and how often?

    9. 9 Questions for the Committee What is the best method to conduct a cognitive or field test with limited time to get the most valid and reliable results? What is the best strategy to notify respondents about the EIA-923?
