1 GW Power Supply: Nuclear vs. PV+Wind+BESS

May 28

I often hear: “We need baseload, that’s why we need nuclear.”
But what does a fair, fact-based comparison look like, 1 GW continuous supply?

Nuclear (realistic experience values)
- CAPEX: €12–15 bn (overnight CAPEX)
- OPEX: €100–120/kW/year ………..

RE Hybrid (PV+Wind+BESS, German benchmarks)
- CAPEX: €4–5 bn
- OPEX: €30–40/kW/year …………

Walk through a 10-year-old PV plant and you see the real cost of shortcuts.
