Evidence
EDF Flamanville 3 site: EPR of about 1,600 MWe; the three-unit site page lists 2x1300 MW + 1x1600 MW. First grid connection 21 Dec 2024. EDF 14 Dec 2025: first time at 100% nuclear thermal power, 1,669 MW gross electrical. EDF still describes industrial commissioning tests as continuing in 2026 — included because it is grid-connected and has run at full thermal power, with that caveat here.Rank 06 of 10
