But that's just a single snapshot in time.

Here's my blogpost going over long term correlation statistics, from two studies, for wind power across Europe.

For comparison, at the start of 2025,
Ørsted sold 12.45% of 3.504 GW of offshore wind capacity, including Hornsea 1 & 2, for £1.745 bn,
which priced the capacity at
£4000/kW of nameplate capacity.

Ørsted sells a 12.45% stake in four UK offshore windfarms.

The sale shows the current market value of UK offshore wind.

The transaction was valued at £1.745 billion, which prices the capacity at £4000/kW of nameplate capacity,
or £10,100/kW of average generating capacity.

 ⬅️ France: 25.8 TWh (=2.6 GW average)
 ⬅️ Norway: 9.3 TWh (=1.1 GW)
 ⬅️ Denmark: 2.6 TWh (=0.3 GW)
 ⬅️ Belgium: 2.1 TWh (=0.2 GW)
 ⬅️ Netherlands: 0.5 TWh (=0.05 GW)

UK net exports were to:
 ➡️ Ireland: 4.5 TWh (=0.5 GW)

Denmark, then France, were the largest electricity exporters to Germany in 2025.

So although France is by far the largest electricity exporter in Europe, and Germany is the third largest importer, it turns out it's not quite as simple as
"Germany is just importing French nuclear".

…and these countries were net exporters to Germany in 2025:

 ⬅️ Denmark: 12.4 TWh (=1.4 GW average)
 ⬅️ France: 11.2 TWh (=1.3 GW)
 ⬅️ Netherlands: 8.4 TWh (=1.0 GW)
 ⬅️ Norway: 7.0 TWh (=0.8 GW)
 ⬅️ Belgium: 3.0 TWh (=0.3 GW)
 ⬅️ Sweden: 2.4 TWh (=0.3 GW)
 ⬅️ Switzerland: 0.9 TWh (=0.1 GW)

A striking feature of 2025 shows up in cross-border electricity trading:

France dominated exports.
It exported 92.4 TWh, or 10.55 GW average throughout the year.

The other three big European economies, Germany, Britain and Italy, were all net importers, importing 101.1 TWh between them.
