Introduction

As winter grips Europe, the region is witnessing the fastest depletion of gas inventories in eight years, driven by a combination of lower-than-expected temperatures and below-average wind speeds. The heating season, which officially started on October 1, has seen a staggering drop of 83 terawatt-hours (TWh) in natural gas storage across the European Union and the UK by November 26.

Inventory Loss and Current Status

This unprecedented pace of inventory loss is more than four times the average rate observed over the past decade and is the steepest decline since 2016. While stocks remain 58 TWh (6% higher than the ten-year seasonal average) as of late November, this figure has narrowed from a surplus of 122 TWh at the winter's outset, indicating a tightening supply situation.

Storage Facilities and Regional Impact

On average, storage facilities across Europe were 87% full, a sharp decline from 97% in 2023 and 94% in 2022. Northwest Europe has faced significantly colder weather compared to the previous two relatively mild winters, resulting in increased heating demand that has further exacerbated the situation.

Heating Degree Days

Major cities like Frankfurt reported 377 heating degree days, closely matching the ten-year average but significantly higher than the numbers from the past two years. London has endured 327 heating degree days so far, marking the coldest start to winter in five years.

Increased Demand and Generation Reliance

These harsh climatic conditions have led to heightened heating requirements, while diminished wind speeds have affected offshore wind generation, leading to an increased reliance on gas-fired power plants. If current trends continue, predictions suggest that the EU and UK could end the winter with around 468 TWh of gas, considerably lower than the 532 TWh projected at the winter's beginning.

Implications for Prices and Supply

The implications of this depletion are serious. While inventories still provide a buffer, rising prices indicate an urgent need for conservation and the attraction of more liquefied natural gas (LNG) to stabilize supply. In November, futures prices on the Dutch Title Transfer Facility rose to an average of €44 per megawatt-hour, up from €36 in September and €26 in February.

Future Supply Concerns

Looking ahead, traders expect that due to the significant drain this winter, Europe will need to import much more gas over the summer of 2025 to replenish reserves. Futures prices for the summer of 2025 are already exceeding those for the winter of 2025/26, indicating anticipated higher demand and cost pressures as Europe strives to secure necessary supplies.

Long-Term Risks

The ongoing situation is concerning not just for this winter but poses a risk for subsequent years as well. If colder-than-normal winters persist, the pressure on gas inventories could escalate, leaving Europe vulnerable to energy shortages. It is imperative for the region to build up stockpiles during the summer of 2025, amidst fierce competition for gas supply from rapidly developing markets in Asia.

Conclusion

As Europe aims to navigate through this challenging landscape, the stakes are rising, and the fallout from potential supply disruptions could reverberate for years to come. Will this winter mark the dawn of a new energy crisis for Europe? The answer remains crucially important as the continent braces for the chill ahead.
