European Union gas storage facilities are currently filled to just over 55% of capacity, marking the lowest level for this period since 2021, according to data from Gas Infrastructure Europe (GIE).

As of the end of the gas day on July 25, EU countries had stored 55.5 billion cubic meters of gas, equivalent to 55.29% of total storage capacity.

During the previous gas day, EU members injected 260 million cubic meters into underground storage facilities, increasing overall reserves by 0.23%.

EU gas reserves lag behind previous years
The current storage level remains significantly below figures recorded during the same period in recent years.

GIE data showed that EU storage facilities were filled to:

54.75% in 2021
67.12% in 2022
84.02% in 2023
83.66% in 2024
76.24% in 2025
The current level is around 18 percentage points below the average recorded for the same period over the previous five years.

The decline comes as European countries continue efforts to rebuild energy reserves ahead of the winter heating season while facing uncertainty over supply routes and global energy markets.

Lower reserves raise winter supply concerns
Russian energy company Gazprom previously warned that European underground gas storage facilities could remain below 75% capacity by October 1 if injection continues at the current pace.

Lower storage levels could create additional pressure during the winter months, when demand for heating increases across Europe.

The European Commission has previously stated that underground gas storage facilities are essential for maintaining supply security, allowing countries to cover up to one-third of their winter gas consumption.

In 2022, the EU introduced gas storage rules requiring member states to fill underground facilities to 90% capacity by November 1 ahead of the winter season.
