As of mid-October 2026, Europe's natural gas storage fill level was around 68% to 70%, below the five-year seasonal average of about 85-89%.

Europe entered the 2026 heating season with gas storage levels significantly below normal. The usual target is to have around 80-90% of storage filled by November for winter safety. However, by mid to late October 2026, storage was only about 68% to 70% full, much less than the seasonal average from the last five years. This lower storage level is a concern for meeting winter energy demand.
