The delay is because these power plants are supposed to replace existing power plants that will be taken offline in 13+ years. What’s notable is they aren’t 1:1 replacements so they are going to end up with a lower percentage of nuclear power.

PS: I reference the a 5 year delay because that’s roughly when you’re spending real money. France could easily back out of this plan in ~7 years having spent less than 1% of what it would cost to actually build a reactor.

If only we had the ability to plan energy policy decades ahead, because we know how long each powerplant will last, and when it will need to be replaced! If only we had energy consumption and CO2 emissions predictions going forwards and backward almost a century!
