As a direct consequence of the decrease in electricity demand in France and Europe, total electricity generation in France fell to 500.1 TWh in 2020, for a year-on-year decrease of 7% (37.4 TWh). This was the lowest level on record in 20 years.
Renewable energy sources accounted for 23.4 % of total electricity production, which was much higher than in 2019. Wind power output rose by 17.3 %, solar power output by 2.3 %, and hydropower generation by 8.4 %. The latter benefited from abundant water reserves, which were about 22 % higher in 2020 than in 2019.
Production from nuclear power and fossil-fired thermal plants decreased by 11.6% (44 TWh) and 10.6% (4.5 TWh), respectively, relative to 2019. These sharp declines were consequences of a health crisis that drove consumption lower and reduced the availability of nuclear power plants. See section: Nuclear generation.

*Renewable hydropower is calculated using a method drawn from EU Directive 2009/28/EC. Seventy percent of hydropower generation is deducted from production at pumped storage stations, or The French acronym for “Station de Transfert d’énergie par pompage”, or pumped storage station.
