Net gas injections into European underground storage (UGS) facilities have slowed to a three-year low in early August 2026, according to data cited by TASS.
The current fill rate stands at 57.87%, significantly trailing the 70% level recorded at the same time last year.
09%, marking the lowest figure for that period in five years.
This deceleration in storage replenishment highlights ongoing challenges in building adequate winter reserves across the bloc.
The weak injection pace follows a difficult summer for European gas markets.
Storage levels ended June at just 49.09%, marking the lowest figure for that period in five years.
July saw injections slow to their weakest pace in six years, driven by a combination of extreme heat reducing demand and constrained supply flows.
