France is the world's largest net exporter of electricity due to its very low cost of generation, and gains over EUR 3 billion per year from this. Thanks to nuclear reactor technology.
France has 59 nuclear reactors operated by Electricité de France (EdF) with total capacity of over 63 GWe, supplying over 430 billion kWh per year of electricity, 78% of the total generated there. In 2005 French electricity generation was 549 billion kWh net and consumption 482 billion kWh - 7700 kWh per person. Over the last decade France has exported 60-70 billion kWh net each year and EdF expects exports to continue at 65-70 TWh/yr.
