The German government is reportedly considering a temporary revival of coal-fired power plants to shore up energy security this winter, a move that has drawn sharp rebuke from UK Energy Minister Grant Shapps, who warned of cascading blackout risks across the continent. The development underscores the fragility of Europe’s energy grid as it pivots away from Russian gas amid the Ukraine war.
According to leaked documents seen by Der Spiegel, Berlin is exploring options to extend the life of several coal plants originally slated for closure, citing “extreme” stress on the power system. The plan, dubbed “Coal Reserve,” would allow plants to generate electricity for a limited period, bypassing previous decarbonisation commitments. German Economy Minister Robert Habeck, a Green party member, has publicly resisted the idea but conceded that “all options must remain on the table to prevent grid collapse.”
Speaking at a press conference in London, Shapps did not mince words. “Germany’s flirtation with coal is a dangerous gamble. It’s like trying to patch a sinking ship with dynamite: you might get a short-term fix, but the explosion will sink everyone.” His warning is rooted in the physics of interconnected grids. Europe’s power network is a synchronised machine. A frequency drop in one country can trigger emergency load shedding in others. If Germany’s grid becomes unstable due to insufficient reserve capacity, the ripple effect could blackout France, the Benelux, and beyond.
The context is sobering. Nuclear generation in France, Europe’s largest electricity exporter, has plummeted to 30-year lows due to corrosion issues in reactors. Meanwhile, Norway has restricted hydropower exports due to low reservoir levels. Hydroelectric output in the Alps is down 20% from the five-year average. This energy trifecta leaves the continent dangerously exposed to any supply shock.
Data from the European Network of Transmission System Operators (ENTSO-E) shows that system adequacy margins for this winter have fallen below 5% in several regions. That is precariously thin. For comparison, the UK’s National Grid ESO has set a minimum buffer of 1.4 GW, about 4% of peak demand. Germany’s margin is just 0.5 GW, representing a 1% buffer. This is the digital equivalent of running a server at 99% capacity: any transient spike crashes the system.
The irony is not lost on climate scientists. Coal is the most carbon-intensive fuel. Burning it for electricity releases roughly twice the CO2 per kilowatt-hour as natural gas. If Germany fires up its coal fleet for a full winter, it could add 30 million tonnes of CO2 to the atmosphere, undoing a year’s worth of emission reductions. As I have said before, you cannot negotiate with the laws of thermodynamics. The planet will warm. The ice will melt. The only question is how much we are willing to sacrifice.
Yet the immediate threat is tangible. The International Energy Agency has warned that Europe could face “unprecedented” energy emergencies this winter, with rolling blackouts possible if cold snaps coincide with low wind speeds. Wind generation has been 15% below the long-term average in recent weeks. Solar output is falling as the days shorten. The grid is tightening like a noose.
Shapps called for a coordinated European response, including demand reduction targets and cross-border solidarity mechanisms. He urged Germany to accelerate its liquefied natural gas terminals and to keep its nuclear plants running. “Coal is a step backwards. It is a failure of policy. We must do better.”
But doing better requires time and political will. The energy transition is not a linear path. It is a chaotic, messy, non-equilibrium process. Sometimes you must take a step back to leap forward. The question is whether that step crushes the biosphere in the process.
As ever, the data tells the story. Germany’s Energiewende was once a beacon of hope. Now it is a cautionary tale. The physics won’t bend to ideology. And the grid won’t wait for politics.
