French electricity exports
Looks like a nuclear success story ? The ramp up seems to match the roll out of nuclear. Until the mid 2000's.
Nuclear output was 430 TWh in 2005 but by 2015 had dropped to 416 TWh because Flamanville-3 and it's nominal 14 TWh were late. Nuclear output has since fallen to a "new record" of 373 TWh
Nuclear output has fallen by the amount of electricity that France used to export. That on it's own proves that France does not export nuclear.
A more nuanced answer is that nuclear needs spinning reserve, and the grid needs high inertia generators nearer the cities than nuclear would ever be allowed for local stability and voltage control. Which leaves an excess of power. France's exports were never just nuclear. And since the other sources provided more power than France exported it could be argued that France never exported nuclear power.
This is where France's increase in exports are coming from now.
From the first chart you can seen Exports dropping from 2006 - 2010 as nuclear output drops by And then rising again after that as renewables come on line. By 2011 wind and solar were producing 14.2TWh , more than offsetting the missing Flamanville-3.
Another way of looking at it is historical French exports could have been covered by the equivalent of it's hydro production. It's another way of showing that overall France doesn't export nuclear. Prove me wrong.
Never forget that France's role in keeping the lights on during the Russian gas embargo was to import electricity and gas from the neighbours.

This is the last 8 weeks excluding nuclear.
The yellow at the top is when non-nuclear dropped below 20GW and you can see there's peaks above 20GW.
The yellow at the bottom is when exports were below 20GW. There's more yellow at the bottom. France exports less than non nuclear produces. And you can see when yellow peaks align, a drop in renewables matching a drop in exports.
France was exporting ~60TWh in the early 2000's but nuclear output has since dropped by ~60 TWh. Can you please square that circle.
We can argue till the cows come home about whether nuclear facilitates exports, but it's share has shrunk and likely to be more plants shut down than opening in the foreseeable future. Meanwhile renewables have expanded massively.

CO2 goes down when there's more wind. ie. less gas being burnt. And visa versa. It isn't rocket surgery.
Note our grid can only take 75% SNSP and there's requirements for spinning reserve and high inertial machines near the cities, though the base level for emissions should fall as we get towards 95% SNSP.

cherrypicking again (but mysteriously still not offer any costings for current path Ireland is being dragged down)
You do realise that electricity usage dropped right across Western Europe due to- Outsourcing all heavy industries to China that the greens love
- Flat populations
Ireland is very much an outlier with our rapidly increasing population in last three decades
Europe as a whole has deindustrialised with Greens being delighted that they can now greenwash away the true cost of wind and solar via China whom use coal and slave labour for these
