Europe spent decades closing coal plants to fight climate change, but soaring gas costs have rewritten the energy playbook, delivering windfall profits to the remaining coal fleet.

A colder stretch and weaker seasonal solar output have forced the continent’s grid back toward conventional fuel. Economics for coal-fired power generation have flipped: Energy Aspects data shows the clean dark spread for German brown coal has jumped to €64/MWh from roughly zero a year earlier, and Volue analysts note that available coal capacity is running at full tilt.

Germany and Poland are the chief beneficiaries. The countries accounted for 74% of the EU’s coal generation last year. Germany, in particular, looks exposed: it retired its last nuclear reactors and pledged to exit coal without building sufficient gas‑fired backup.

Earnings for generators are set to climb as winter arrives. Forecasts point to brown coal spreads breaching €70.50/MWh between November and March. Hard‑coal plants have also swung back into the black, posting an average October margin of near €37.30 versus losses a year earlier.

The one constraint on the sudden coal renaissance is logistics. Critically low water levels in the Rhine and other rivers are hampering barge deliveries of hard coal and could force some operators to scale back output.
