Efficiency (electricity and heat) from public conventional thermal plants, 1990 and 2005

Output from conventional thermal power stations consists of gross electricity generation and also of any heat sold to third parties (combined heat and power plants) by conventional thermal public utility power stations as well as autoproducer thermal power stations.

Due to inconsistencies in the Eurostat data set regarding public production in Luxembourg (input data is registered, output data is zero in 1990) and Norway (efficiencies >100%), this data is excluded from the figure and in total efficiency, but only for 1990.
