This study does not include their most recent attempt at Flamanville.

> Construction on a new reactor, Flamanville 3, began on 4 December 2007. The new unit is an Areva European Pressurized Reactor type and is planned to have a nameplate capacity of 1,650 MWe. EDF estimated the cost at €3.3 billion and stated it would start commercial operations in 2012, after construction lasting 54 months. The latest cost estimate (July 2020) is at €19.1 billion, with commissioning planned tentatively at the end of 2022.
