0.44 euro per kW.h. France does generate a lot of it's power with 
nuclear reactors, when they work. That wasn't driven by economics, but 
by Charles de Gaulle's ambition to have a nuclear armed force de frappe.

They aren't all that flexible as a generating service, so France mostly 
sell power to its neighbours when it's consumers are using less and the 
neighbouring consumers are using more.
