Europes power market tilts back to coal as utilities prepare for fuel switching

• • Coal futures surpass spot prices, end-users restock to build inventories

• • Natural gas prices remain steady but storage concerns escalate

The European thermal coal market has staged a notable recovery, with spot prices climbing higher as a combination of index rollovers, tightening supply, and persistent geopolitical tensions reshapes trading dynamics across the Atlantic basin. While natural gas prices have remained relatively stable for the time being, the evolving economic relationship between the two fuels is keeping the prospect of gas-to-coal switching firmly on the agenda for European power generators.

Spot prices rebound as contango encourages storage activity:

Spot physical coal prices delivered into the Amsterdam-Rotterdam-Antwerp (ARA) hub have moved sharply higher, with prompt cargoes trading above the best bid levels. Offers for May-loading, non-Russian origin cargoes have been heard at a significant premium to bids, reflecting a market where sellers are regaining confidence. End-users with available storage capacity are increasingly taking advantage of a strong contango structure (futures higher than prompt or spot prices), purchasing cargoes for near-term arrival while avoiding steeper premiums for later delivery.

The aggressive discounting of spot cargoes seen in recent weeks has slowed. The narrowing gap between spot physical and financial paper suggests that traders are recalibrating their positions, with attention gradually shifting toward longer-dated contracts. Strong bidding interest has emerged for Cal-27 coal, as market participants begin to factor in potential fuel-switching dynamics later this year. However, trading volumes are expected to remain thin in the immediate term, with many European traders away for the Easter holiday period.

Gas prices steady but vulnerable as storage concerns mount:

Natural gas prices across Europe have remained broadly flat, but underlying fundamentals point to increasing vulnerability. European Union gas storage facilities are currently filled to less than 30% of capacity, a sharp contrast to the same period last year, when inventories stood at over 40%.

Despite having entered the official restocking period, significant injections have yet to materialise. Norwegian gas flows to Europe remain marginally below recent levels, while LNG contract prices for delivery to Northwest Europe have held steady. LNG inflows remain below normal levels, especially from the Persian Gulf. This fragile supply situation, compounded by ongoing geopolitical instability in the Middle East, means that any further disruption could quickly push gas prices higher, thereby improving the competitiveness of coal-fired power generation.

The combination of low storage and weak restocking activity is quietly setting up a structural risk for both summer and winter gas balances.

Coal vs gas: Switching economics back in focus:

The most important development is the return of gas-to-coal switching economics. Forward markets are already pricing this in. A steep contango structure, where future prices are higher than prompt, is a strong signal that utilities expect higher coal burn later and that coal will regain marginal competitiveness against gas.

Utilities with storage capacity are already buying cheaper prompt coal and stockpiling it rather than paying higher prices for forward cargoes. This behaviour is classic pre-switch positioning, with the market clearly preparing to transition to coal.

The theoretical switching price at which gas becomes more expensive than coal for power generation is being closely monitored. With gas storage low and LNG flows uncertain, that threshold is drawing nearer.

Italy extends coal plant operations in major policy shift

In a significant development for the European coal market, the Italian government has proposed extending the operational life of two major coal-fired power plants until 2038. The plants in question are Enel’s Brindisi Sud and Torrevalladiga Nord, with a combined capacity of approximately 3.7 gigawatts. Both had ceased to be authorised for coal use from the start of 2026 and were declared unavailable, but the new amendment would effectively reverse that decision.

The proposed extension is linked to the anticipated arrival of small modular nuclear reactors in Italy by the late 2030s. Two other operational plants on the island of Sardinia remain listed as essential for the security of the electric system, with their continued operation expected until a mainland interconnection project is completed, likely by 2029.

While Italian coal plants produced only a small fraction of the country’s electricity last year, the policy shift underscores the growing primacy of energy security concerns over decarbonisation timelines in parts of Europe. Coal remains a strategic fallback fuel.

Supply-side dynamics: Atlantic basin tight but fragmented:

In the Atlantic Basin, competitive supply options remain limited. South African FOB Richards Bay prices for 5,500 kcal/kg coal have softened slightly, while US coal pricing remains mixed, with Gulf Coast weakening as East Coast netbacks show some improvement. However, delivered competitiveness remains uneven. South Africa and Colombia are currently out of the money into Asia and even parts of Europe, as freight and quality differentials limit arbitrage flows between basins.

Freight remains a constraint. Panamax rates from Richards Bay to key destinations remain elevated, limiting arbitrage flexibility. This fragmentation means that European buyers are not awash with competing supply options, providing underlying support to prices.

Demand signals: Quiet now, stronger later:

Current demand in Europe remains muted, but this is misleading. End-users are not aggressively chasing prompt cargoes. Instead, they are optimising procurement timing and taking advantage of storage combined with the contango opportunity. This creates a false sense of weak demand while underlying forward demand expectations are actually strengthening.

The market is therefore transitioning from a phase of no demand to one of latent demand. When switching begins, it could be sharp rather than gradual.

Outlook for European, Atlantic coal markets:

The European coal market has entered a phase of cautious recalibration. A supportive forward curve is providing price stability. While natural gas prices are not yet high enough to trigger a widespread fuel switch, critically low storage levels and ongoing geopolitical risks mean that the threshold for such a switch is steadily lowering. Longer-dated contracts signal that the market expects coal demand to rise if gas prices firm and storage remains weak. However, key risks to this outlook include a faster-than-expected recovery in LNG flows, which would cap coal upside, or an escalation of the ongoing war, which would sharply accelerate coal demand.
