Europe coal burn finds support as gas economics, low storage revive dispatchable fuel demand

• Coal outcompetes gas in Europe's power market
  
  
• Energy security supporting thermal generation demand
  
  

Europe's coal market is regaining relevance as fuel economics, gas storage concerns and uneven renewable output improve the competitiveness of dispatchable thermal generation. While this does not signal a broad return to coal, recent market movements show that coal-fired power can still recover quickly when gas remains structurally expensive and renewable generation underperforms expectations.

Coal generation outperforms seasonal expectations

Coal burn in Europe, particularly in Germany, has remained stronger than normal for the shoulder season.

German hard coal-fired generation averaged around 3 GW during 11-17 May, down marginally week-on-week but still significantly above the 1.3 GW recorded during the same period last year. This translated into an estimated load factor of around 75% for available hard coal-fired capacity, an unusually firm level for a period that typically sees lower thermal generation.

The increase has not been driven by stronger power demand but by relative fuel economics. While wind generation improved materially during the week, coal remained economically more attractive than gas.

ARA stocks rise but logistics remain constrained

Coal inventories at the Amsterdam-Rotterdam-Antwerp (ARA) hub continued to build, although logistical bottlenecks along the Rhine prevented a faster movement of material inland.

ARA stocks increased by 55,000 t week-on-week to 3.28 Mnt on 17 May, supported by firm import volumes. Stocks at Rotterdam's EMO terminal rose by 100,000 t to 2.2 Mnt, partially offset by lower inventories at Amsterdam and Vlissingen terminals.

However, low Rhine water levels continued to limit full-capacity barging. Water levels at the key Kaub measuring point remained below the threshold required for optimal inland transport, slowing deliveries to downstream utilities and helping sustain stronger coal burn.

Gas remains less competitive than coal

The strongest support for coal has come from comparative generation economics.

June clean dark spreads for 40%-efficient coal-fired plants averaged around minus EUR 8.48/MWh during 11-15 May, compared with minus EUR 24.75/MWh for 55%-efficient gas-fired units. While coal-fired generation remained loss-making on a clean spread basis, it was significantly less unprofitable than gas, encouraging utilities to continue running coal units.

At the same time, Europes gas storage position remains less comfortable than last year. EU gas storage stood near 36.6-36.8% in mid-May, below year-ago levels, implying that summer injections will need to remain robust and limiting the likelihood of a sharp fall in gas prices without meaningful demand destruction or stronger supply growth.

Coal prices strengthen as utilities reassess fuel economics

Coal prices have already begun responding to the firmer demand backdrop.

Argus assessed CIF ARA 6,000 NAR at $114.19/t on 19 May, up $1.04/t d-o-d, while Platts assessed prompt CIF ARA 6,000 NAR at $118/t on 20 May, marking a sharp daily gain of $6/t. The divergence between physical and forward markets suggests utilities remain cautious but are increasingly factoring in stronger coal burn economics into summer.

Energy transition shifts toward reliability

Europe's broader energy conversation is also shifting. Rather than reversing decarbonisation, policymakers are increasingly rebalancing energy security and system reliability alongside emissions reduction goals. Nuclear power is receiving renewed attention in several markets, while dispatchable generation - including coal and gas - continues to play an important stabilising role during periods of weaker renewable output.

Outlook: Economics remain supportive into Q3

The near-term outlook for coal remains cautiously supportive. Higher inventories may limit sharp spot rallies, particularly if Rhine logistics improve or gas prices soften. But as long as gas-fired generation remains materially less competitive and storage injections remain a priority, coal is likely to retain a meaningful role in Europe's generation mix through summer and into the third quarter.
