Where does power flow — and why do prices split?
Geography of Price
One country, one price — until the grid can't carry the power across it. Four countries, four answers to the same congestion problem, on the map.

How far neighbouring zones' prices drift apart — and the cross-border flow that explains it.
Germany North–South Map view
Wind in the north, demand in the south, one price between them — so clean power gets curtailed.
France Nuclear Map view
The centralised mirror: 57 reactors, who exports, who imports, and what it really costs.
Nordic Price Zones Map view
The split Germany debates, already live — twelve zones, a cheap hydro north, a dear south.
UK Regional Map view
Britain's answer: keep one price, pay Scottish wind to switch off.
Curtailment Chart
Clean power thrown away when the grid can't move it — the cost of the bottleneck, in MWh and €.
The euro figure is an estimate at a reference price, not a settled cost.

The internal north–south congestion made legible — and the single-zone debate, even-handed.
The split-zone effect is a cited range from published studies, not an assertion.
