Notes
COD tension flagged 2026-09-28: WNA table said grid 2026 but Sep 2026 has no startup; NEI Mar 2026 expects unit-2 operation in 2027 — estimate retained at 2026 pending Rosatom/WNA revision. Context: unit 1 (Kursk II-1) entered commercial operation 2026-05-01 after Dec 2025 grid connection (WNN/Rosenergoatom); all four VVER-TOI units targeted by 2034.
