Germany has spent the better part of a decade building its international reputation around one particular story: an aggressive, legally binding shift away from coal and toward renewable energy. So when reports surfaced that lawmakers were reviewing whether to bring mothballed coal plants back online, it understandably raised a lot of eyebrows. Is Germany actually reversing course on coal?
The honest answer is more nuanced than a simple yes or no. Germany isn’t abandoning its coal phase-out — but a fresh energy crisis has forced a real conversation about slowing it down, at least temporarily, in the name of keeping the lights on and prices manageable.
The Backdrop: Germany’s Coal Commitment, in Brief
Germany’s coal phase-out is governed by a 2020 law that set a legal deadline of 2038 for ending coal-fired electricity generation entirely, with built-in checkpoints in 2026, 2029, and 2032 to assess whether the timeline could be moved up. At the time the law passed, environmental groups criticized 2038 as far too distant — and for years, the actual trajectory suggested they may have been right to push for faster action: coal’s share of German electricity generation fell from roughly 23.3% in 2020 to about 20.4% in 2025, while renewables climbed from around 44% to more than 57% over the same period. More than 14 gigawatts of coal capacity had been retired by the end of 2025 — roughly a third of the total capacity that existed when the phase-out law was signed.
That progress made Germany one of only a handful of countries with a coal exit trajectory that analysts considered genuinely consistent with its climate targets. But “on track” and “immune to disruption” are two very different things — and 2026 has tested that distinction.
What Changed: A Fresh Energy Crisis
The current reconsideration of coal traces back to a familiar pattern: geopolitical instability driving up energy prices. This time, the disruption stems from an escalating conflict involving Iran, which has rattled oil and gas markets in a way that echoes the shock Europe experienced after Russia’s invasion of Ukraine in 2022.
Speaking at a conference in Frankfurt, Chancellor Friedrich Merz acknowledged that Germany may need to keep existing coal plants running longer than planned if the energy crisis continues and an actual supply shortage materializes. His reasoning centered on the lack of fast alternatives: the three nuclear plants Germany shut down in April 2023 cannot be technically restarted on a short timeline — operators have indicated it would take five to ten years to bring them back, time Merz said the country doesn’t have. With nuclear off the table as a near-term option and next-generation solutions like fusion power still in early research stages, coal remains one of the few large-scale sources of backup capacity Germany can access quickly if supply tightens.
Shortly afterward, lawmakers from both parties in Germany’s governing coalition — Merz’s conservative CDU/CSU alliance and their Social Democrat coalition partners — agreed to formally review reactivating coal plants that had been placed in reserve status specifically to reduce elevated energy prices tied to the crisis.
What “Reserve” Coal Plants Actually Means
It’s worth understanding what’s actually being discussed here, because “bringing coal back” sounds more dramatic than the mechanism involved. Germany maintains a so-called grid reserve — plants that have already been taken off the regular electricity market but remain available to feed power back into the grid specifically when operators need to bridge short-term bottlenecks or supply gaps. As of the most recent figures, around 10 gigawatts of coal-fired capacity sit in this reserve status, including a significant portion of the country’s remaining hard coal capacity.
The current review is about whether to make fuller, more active use of that existing reserve mechanism — not about approving new coal plant construction or reversing the legal 2038 phase-out deadline itself. That distinction matters: this is a conversation about the pace and flexibility of an already-agreed transition, not a fundamental reversal of German energy policy.
The Bigger Problem: A Backup Capacity Gap
Underlying all of this is a structural issue that predates the current crisis: Germany’s plan to replace retiring coal capacity with new gas-fired backup plants has been running behind schedule for years. The government has proposed building around 12 gigawatts of new gas plants specifically to provide flexible backup power as coal and other sources phase out, but the auctions needed to actually greenlight that construction have faced repeated delays.
Germany’s economy minister has signaled plans for two auction rounds later in 2026, but even under an optimistic timeline, industry estimates suggest it takes roughly five years to go from auction to an operational gas plant — meaning meaningful new backup capacity is unlikely to come online before the early 2030s. That gap between when coal capacity is scheduled to disappear and when its replacement infrastructure will actually be ready is precisely what’s driving the pressure to keep some coal plants available as a stopgap.
Is the Phase-Out Actually at Risk — Or Just Delayed?
Here’s where the story gets genuinely interesting: even as politicians debate keeping coal plants available for emergencies, market economics are arguably pushing in the opposite direction, and faster than regulation requires.
According to cost estimates from German energy company EnBW, generating electricity from new onshore wind costs roughly 4.3 to 9.2 cents per kilowatt-hour, and solar between 4.1 and 14.4 cents. Hard coal, by comparison, costs between 17.3 and 29.3 cents per kilowatt-hour, with lignite (brown coal) between 15.1 and 25.7 cents — and that’s before factoring in carbon pricing under the EU’s Emissions Trading System, which adds roughly another 7 cents per kilowatt-hour on top of coal’s cost. By EnBW’s own assessment, that pricing gap makes coal power increasingly uneconomical regardless of what the legal phase-out deadline says.
Researchers modeling Germany’s electricity market have echoed that view, suggesting the country’s last coal plant could plausibly close by the early 2030s — years ahead of the legally mandated 2038 deadline — purely as a function of coal becoming too expensive to compete with renewables, independent of any political decision at all. As one researcher at the Institute of Applied Ecology put it, the market appears to be outpacing the government’s own schedule.
That creates a genuinely unusual dynamic: politicians actively discussing whether to lean on coal more heavily in the short term, even as the underlying economics of coal power continue to erode beneath them.
Germany Isn’t Alone
Germany’s coal reconsideration isn’t happening in isolation. Italy, facing the same regional energy crisis, voted to push back its own coal phase-out deadline dramatically — from an original target of 2025 all the way out to 2038 — allowing some plants to remain on standby under an “energy security” justification, with operators compensated for keeping them idling as designated strategic assets.
That move drew sharp criticism from energy analysts, with one describing the legislative shift as a worryingly backward-looking signal, given that coal represents a minor share of Italy’s power mix and isn’t expected to become more significant regardless of the extended deadline. The core critique — that leaning on old, largely non-operational coal capacity offers uncertain security benefits while potentially raising costs for consumers already facing high electricity prices — is a tension that applies to Germany’s situation as well, even though Germany’s coal fleet remains considerably larger and more actively used than Italy’s.
What Happens Next
Germany’s government has a long-delayed official assessment due in August 2026 — the first formal stocktake evaluating the coal phase-out’s real-world effects on supply security, electricity prices, greenhouse gas emissions, and the coal-producing regions whose economies remain tied to the industry. That report, five years after the original phase-out law passed, is expected to shape whether the government leans toward accelerating the exit (as market economics increasingly suggest is possible) or toward preserving more flexibility to lean on coal during future supply disruptions.
For now, the practical answer to “is Germany looking again at coal” is: yes, but narrowly and reluctantly. This is a government reaching for an existing emergency mechanism to manage a genuine supply-security concern during an active geopolitical crisis — not a wholesale policy reversal on climate commitments. Whether that emergency posture becomes a longer-term pattern will likely depend on how the current energy crisis evolves, how quickly delayed gas plant auctions actually deliver new backup capacity, and whether the economics of coal continue eroding fast enough to make the entire debate moot before Germany’s 2038 deadline ever arrives.
The Bottom Line
Germany isn’t abandoning its coal phase-out, but it is actively weighing whether to use existing reserve coal capacity more heavily to manage a supply-security scare triggered by a fresh geopolitical energy crisis. At the same time, the underlying economics of coal power continue to weaken independent of politics, with several analysts suggesting the market alone could push Germany’s last coal plant offline years ahead of its legal 2038 deadline. The real story here isn’t a reversal — it’s a country trying to manage a short-term energy security gap without abandoning a long-term transition that, on the numbers, appears to be succeeding largely on its own.
