In recent years, the European energy landscape has undergone significant transformations, driven by geopolitical tensions and shifts in the global market. In this context, Ukraine’s announcement to increase natural gas imports by 40% compared to the previous year marks a strategic turning point not only for the country but for the overall energy balance of Eastern Europe.

A significant increase to ensure energy security

According to official statements from the Ukrainian Gas Transmission System Operator (GTSOU), Ukraine will import around 1.1 billion cubic meters (bcm) of gas during peak months in 2025, up from 800 million in 2024. This 40% increase reflects the country’s need to diversify its supply sources, reduce dependence on unreliable imports, and strengthen internal reserves ahead of winter.

Kyiv’s decision responds to a dual need: meeting domestic energy demand and ensuring the operational continuity of its transmission system, which remains crucial for gas transit to other European countries.

Import routes: Slovakia takes the lead

A key element of this strategy is the origin of the imported gas. Slovakia currently plays a primary role as a key entry point, serving as a central hub for non-Russian supply routes. About 785 million cubic meters, or over 70% of the planned total imports, will flow through Slovak pipelines, with the remaining volumes divided between Hungary and Poland.

This approach is not new. Since 2022, Ukraine has steadily increased westward imports, leveraging reverse-flow infrastructure to receive gas from EU countries, which themselves source gas from diversified suppliers like Norway, North Africa, U.S. LNG, and others.

A move aligned with Europe’s energy transition

Ukraine’s import increase fits into the broader context of energy transition and supply security. Since the war began in 2022, many European countries have recalibrated their energy policies to reduce dependency on Russian gas. While not an EU member, Ukraine has followed a policy aligned with the European bloc, accelerating diversification and building a more resilient energy system.

This choice also strengthens Ukraine’s position as a strategic partner in Europe’s gas supply. Its gas transmission system remains one of the largest in the continent and, despite war-related damage, continues to play a vital role in regional supply balancing.

Storage and winter readiness: the real challenge

A major driver behind the increase is the need to fill storage facilities ahead of the 2025–2026 winter. Ukraine’s system includes over 30 bcm of storage capacity, part of which is used by European operators for their own strategic reserves.

To face the cold season without interruptions, Kyiv has developed an accumulation plan based on steady summer imports, also capitalizing on the flexibility of spot contracts and opportunities in the European market. The imported gas will partly serve internal consumption and partly be resold during high-demand periods, creating both economic and energy benefits.

GTSOU’s role and international cooperation

The state-owned GTSOU has stated that the increase in imports results from active cooperation with European partners, including ENTSOG, the association coordinating European transmission system operators. Agreements have been signed to facilitate transmission capacity and market access, even through virtual reverse flow mechanisms.

This demonstrates how Ukraine’s energy security is increasingly integrated into the European framework, despite the ongoing conflict. Ukraine has managed to adapt, modernize its operations, and adopt EU-compliant practices.

Economic and geopolitical impacts

The 40% import increase is more than a technical update. It is a strong political message, highlighting the country’s determination to remain an active energy player, aiming for stability, independence, and international cooperation.

Economically, this investment is expected to positively impact Ukraine’s entire energy sector, sustaining demand and promoting greater industrial competitiveness. Moreover, improved interconnections could spark new investment opportunities in infrastructure and technology, such as compressor upgrades, digital control systems, and smart storage management.

Looking ahead

Beyond 2025, Ukraine is also working on other fronts, especially in the development of renewable energy and green hydrogen, in line with European goals for 2030 and 2050. However, gas will continue to play a central role in grid stabilization, particularly in winter months.

The strengthening of Ukraine-EU energy relations, further supported by this import growth, could lay the groundwork for integrated future developments. Creating a more interconnected and resilient single gas market remains a strategic priority—one in which Ukraine aims to play an active and long-term role.
