Increase in Natural Gas Reserves in Ukraine
As of September 14, 2025, natural gas reserves in Ukraine's underground gas storage (UGS) facilities surpassed last year's figures for the first time, reaching 12.055 billion cubic meters.
This information was reported by the publication ExPro.
On this date, there were 12.055 billion cubic meters of gas stored in Ukraine's UGS, while a year ago, there were 12.05 billion cubic meters, which is 0.05% or nearly 5 million cubic meters less.
It is expected that this gap will widen in the coming days.
The publication reminded that at the start of this year's injection season (April 17), there were nearly 5.41 billion cubic meters of natural gas in Ukraine's UGS, which is 35% or 2.95 billion cubic meters less than on April 17, 2024. Throughout the injection season, Ukraine was able to completely close this gap, primarily due to increased imports.
Since the beginning of the injection season, nearly 6.68 billion cubic meters of gas have been injected into Ukraine's UGS, which is 1.67 times more than in 2024. Furthermore, more gas was injected into storage in 2025 than was stored in UGS at the end of the heating season.
In particular, in September 2025, Ukraine is injecting an average of 53.9 million cubic meters of natural gas into storage daily, which is 2.3 times more than in September 2024. About half of the injection volumes consist of imported resources.
The average daily import volume in September is 23.6 million cubic meters, mostly provided by the state-owned company Naftogaz of Ukraine.
It is worth noting that the filling level of underground gas storage in the European Union reached 80% (86 billion cubic meters of natural gas) on September 13-14. This is the lowest filling level in the EU since the beginning of the full-scale Russian invasion of Ukraine, although this year's reserves are higher than in 2021.
