IEA Home > Statistics Home > Definitions Electricity Plants Electricity plants refers to plants which are designed to produce electricity only. If one or more units of the plant is a CHP unit (and the inputs and outputs can not be distinguished on a unit basis) then the whole plant is designated as a CHP plant. Both public and autoproducer plants are included here. Columns 1 to 8, show the use of primary and secondary fuels for the production of electricity as negative entries. Gross electricity produced (including power stations' own consumption) appears as a positive quantity in column 9, "Electricity". Transformation losses appear under "Total", column 11, as a negative number. (1) Public supply undertakings generate electricity and/or heat for sale to third parties as their primary activity. They may be privately or publicly owned. Note that the sale need not take place through the public grid. (2) Autoproducer undertakings generate electricity and/or heat, wholly or partly for their own use as an activity which supports their primary activity. They may be privately or publicly owned.
