Gross consumption was lower than in 2019 in all the French regions, due to the health crisis. Declines ranged between 3.1 % (in Brittany, where gross consumption fell 0.7 TWh) and 6.6 % (Ile-de-France, where gross consumption ended the year down by more than 4.5 TWh). The health crisis had an uneven effect on electricity consumption in the different regions, notably because the breakdown of consumption by sector changes from one region to the next.

Between 2006 and 2019, trends in adjusted consumption in France were mixed, due to a variety of factors, one of which was demographics. This was the case for instance in Occitanie, where electricity consumption increased by 9.5 % while the population grew by 10.3 % in 2006-2019 (Insee data).

The Grand Est region saw the steepest decrease in consumption in France (more than 11 %), driven by deindustrialisation.

The Hauts-de-France, Grand Est and Auvergne-Rhône-Alpes regions are home to the largest number of industrial sites connected to the transmission grid. Due to the health crisis, power demand in heavy industry declined sharply across all these regions relative to 2019. Decreases ranged between 5.6% (Pays de la Loire, where consumption contracted by 0.1 TWh) and 14.6% (in Occitanie, which saw a 0.3 TWh decline). In Auvergne-Rhône-Alpes, consumption fell by more than 1.5 TWh. Power consumption for rail transport dropped by between 13 and 26% year-on-year, depending on the region, with decreases exceeding 0.3 TWh in Hauts-de-France and Ile-de-France; year-on-year declines in power consumption by the steel industry ranged between 8 and 34% depending on the region, and exceeded 0.6 TWh in Auvergne-Rhône-Alpes and Hauts-de-France
