Nuclear energy, in the form of fission, is the primary source of energy in France. In 2004, fission energy made up the largest share of France's energy consumption at 39%. Looking purely at electricity, though, 416.800TWh (76.337%) out of the country's total production of 546TWh of electricity was from fission-electric power stations, the highest percentage in the world.
Électricité de France (EDF) – the country's main electricity generation and distribution company – manages the country's 58 power reactors. EDF is substantially owned by the French Government, with around 85% shares in government hands. EDF has said its uncompleted third-generation nuclear reactor European Pressurized Reactor (EPR) project, the Flamanville Nuclear Power Plant, will be delayed until 2018, due to "both structural and economic reasons," which will bring the project's total cost to €8.5 billion.
As of 2012, France's electricity price to household customers is the seventh-cheapest amongst the 28 members of the European Union, and also the seventh-cheapest to industrial consumers, with a rate of €0.14 per kWh to households and €0.07 per kWh to industrial consumers. France was the biggest electricity exporter in the EU in 2012, exporting 45TWh of electricity to its neighbours. With very inclement weather, when demand exceeds supply, France infrequently becomes a net-importer of electricity in these rare cases, due to the lack of more flexible generating plants.
France's nuclear power industry has been called "a success story" that has put the nation "ahead of the world" in terms of providing cheap energy with low CO2 emissions. However, recent opinion polls show that less than 50% support nuclear power, and following François Hollande's victory in the 2012 Presidential Election, there may be a partial nuclear phaseout in France, with his Socialist party in favour of closing the oldest 24 reactors by 2025.
