Little change in breakdown by sector


The breakdown of consumption by sector was comparable to 2017. It should be noted that the slight decrease in consumption in heavy industry followed significant social movements in the rail transport sector and an incident at the site of an industrial customer in the metallurgy sector.

The residential segment was once again the largest consumer of electricity, accounting for about 35.7% of final consumption, followed by the business sector (26.6%), heavy industry (16.9%), SMEs/SMI (11%) and professionals (9.9%).

Who are RTE’s customers?

RTE works on behalf of society and its own customers – producers and distributors of electricity, industrial firms and traders – to offer solutions that help keep power system costs in check and thus preserve economic activity.

As the transmission system operator, RTE plays a central role in the power system and is responsible for ensuring that generation always matches demand. It works around the clock, seven days a week, to direct electricity flows and optimise the functioning of the power system for its customers and society at large. RTE carries electricity to all parts of France, from generation sites to the industrial sites that are directly connected to its network and to the distribution grids that deliver it to final consumers.

Consumption was stable on the distribution networks and among SMEs/SMI, professionals, businesses and residential users


Electricity consumption, including the losses of distribution networks and adjusted for seasonal factors, was stable among SMEs/SMI, professionals, businesses and residential users connected to the distribution grids.

The application of directives and regulations on the energy efficiency of equipment contributed to this trend. Another factor was slower growth in the share of new buildings heated with electricity, due to the application of the 2012 Building Energy Regulation.

Demand contracted slightly in heavy industry


Electricity consumption by industrial users* directly connected to the public transmission network reached 66.2 TWh, which was 1.8% lower than in 2017. This year-on-year decrease was driven primarily by significant social movements in the rail transport sector in the spring and an incident at the site of an industrial customer in the metallurgy sector.
