Name of the national data collection Additional techniques used for the compilation of the final data set Details
E01_energy resources and consumption in year….
  • Weighting values
  • Imputing missing/non-response rate
  • Cross-checking techniques
  • Grossing up the sample
  • Outliers are aligned or streamlined
  • Incorrect data is adjusted or corrected
  • Adjustment due to different units/concepts…
 The primary data are edited and checked at county level using a VisualFoxPro application designed by NIS IT experts, and then the files are sent to NIS head office, where the remaining errors are corrected.
The data are checked for completeness, consistency and coherence.
After the validation of primary data, the final weights for grossing up procedure are established according to the type of non-response that is associated to each unit without data.
The weights, that are the inverse of the sampling fraction, are calibrated and redressed based on the total energy consumption (in t.o.e.) computed for each responding unit.
E02_production of electricity and heat
  • Imputing missing/non-response rate
  • Incorrect data is adjusted or corrected
  • Adjustment due to different units/concepts…
 The big number of small wind and photovoltaic producers make difficult to obtain direct information from all of them, therefore the electricity production and capacities for these producers are imputed from administrative sources.
