Risks peaked in February, when large-scale Russian missile attacks on gas production facilities led to the sudden loss of nearly half of the state’s output. These events created a perfect storm that could have caused a nationwide gas blackout at any moment.
That outcome was avoided. Quick action by the management team, close coordination across the Group companies, strong government support, and full mobilization of personnel allowed Naftogaz to stabilize the system. The company restored damaged infrastructure, secured urgent gas imports, and maintained uninterrupted supply for all consumer categories, with no outages reported.
More than 100,000 Naftogaz Group employees worked under extreme conditions. Naftogaz employees shielded equipment from shelling, repaired damaged facilities, and kept operations running. The company managed to stabilize the situation. Roman Chumak, Acting Chairman of the Executive Board of Naftogaz Group expressed his gratitude to every Naftogaz employee, international partners, the Supervisory Board, the Ministry of Energy, the Government, local authorities, and the Armed Forces for their coordination and support during the most difficult heating season.
Key results of the 2024/2025 heating season:
- Ukrgasvydobuvannya: loss and recovery of production
Naftogaz Group facilities have been subjected to repeated massive enemy shelling. In 2024–2025, 34 Ukrgasvydobuvannya sites were attacked. The most destructive strike occurred in February 2025, causing significant damage to state-owned gas production, with losses reaching nearly 50% of volumes.
To sustain the heating season and compensate for the losses, Naftogaz urgently imported 800 million cubic meters of gas, balanced the system, and launched restoration efforts for the damaged infrastructure.
The team of Ukrgasvydobuvannya restored facilities, mobilized additional equipment, and by March recovered more than half of the gas production lost during a wave of attacks earlier this year.
Despite the war, Ukrgasvydobuvannya met targets under its production program. It commissioned 83 wells and reached total output of 14.6 bcm in 2024—the highest annual volume across Naftogaz Group companies since 2017.
The company also completed more than 30 ground infrastructure modernization projects, securing additional production of 300 million cubic meters, which is 137% higher than in 2021 and 3% above 2023 levels.
- Gas supply company: serving all consumer categories with gas and heat
Naftogaz Group remains a reliable gas supplier for households, businesses, district heating companies (DHC), and electricity producers. In 2024, gas was consistently delivered to 12.5 million household consumers, 1,271 district heating companies (DHCs), 79 industrial consumers, 136 electricity-consuming businesses, 2.3 thousand small and medium-sized enterprises, 14 gas distribution system operators (DSO), and 7.6 thousand budgetary and religious organizations. All these consumer categories received stable and reliable gas supply from Naftogaz.
The company continues to invest in improving customer service. A team of 550 contact center operators responds to customer inquiries quickly and efficiently.
- Ukrtransgaz: reliable gas storage despite infrastructure attacks
Ukraine’s underground gas storage (UGS) facilities rank first in Europe and third globally. During the 2024/2025 heating season, these facilities came under combined enemy attacks. Despite this, the Ukrtransgaz team ensured the stable functioning of the gas storage system and the safe injection and withdrawal of gas.
After the January 2025 shelling, the Group promptly restored the damaged UGS infrastructure. Naftogaz has passed this test multiple times, and if new strikes occur, repair equipment is already on the way. The Group demonstrated the resilience of Ukraine’s underground gas storage system, mobilized all necessary personnel and services, and maintained operations throughout every attack.
- Kryvyi Rih, Mykolaiv, Kherson: saving the heating season
The situation in Kryvyi Rih, Mykolaiv, and Kherson during the heating season was critical. Continuous enemy shelling and the poor condition of local networks threatened to leave over 1 million people without heat and electricity. In Kryvyi Rih alone, 70 emergency crews from Naftogaz Group companies worked around the clock, backed by essential machinery and equipment.
In addition to our own resources, we attracted humanitarian donor assistance in the form of equipment, cranes, gas piston units and other assets worth over UAH 5 billion. This helped save the heating season in several cities, including Kryvyi Rih, Mykolaiv and Kherson. It will also support the development of cogeneration capacity,” said Roman Chumak.
A total of 470 emergency teams operated around the clock to conduct urgent repairs and restore gas supply after damage or shelling.
- No collapse after transit halt
On January 1, the transit of Russian gas was halted. Naftogaz ensured the stable operation of the gas transmission system by coordinating the work of dispatch centers at Ukrtransgaz, the gas distribution system operator, and the Operator of the Gas Transmission System of Ukraine (OGTSU).
“There was no collapse. Consumers did not experience any negative impact from the transit interruption,” said Roman Chumak.
- Management efficiency and support for the economy
To respond quickly and effectively to challenges, Naftogaz strengthened coordination between Group companies in carrying out repair and production tasks, and optimized internal processes. The Group granted more autonomy to its companies and simplified procurement and other procedures essential for restoring facilities.
Despite a difficult operating environment, Naftogaz increased revenues from gas sales to UAH 90.7 billion, which is UAH 14.1 billion more than the previous year. The overall payment collection rate reached 90%.
Naftogaz remains a pillar of the national economy. In 2024, the company paid more than UAH 104 billion to the state and local budgets, UAH 14 billion more than in 2023. This represents 7% of Ukraine’s consolidated budget, making Naftogaz one of the country’s largest taxpayers.
Naftogaz invested over UAH 1 billion to protect infrastructure at more than 130 of the Group’s critical sites. These measures included engineering fortifications, electronic warfare systems, and mobile fire groups. These efforts helped reduce the impact of enemy attacks.
Preparing for the 2025/2026 heating season
Naftogaz is already working on preparations for the next winter.
“Since the beginning of the year, 1.5 billion cubic meters of gas have been contracted: 800 million cubic meters were urgently imported early in the year, 400 million cubic meters will be delivered to Ukraine as part of the winter readiness plan. In addition, Naftogaz purchased 300 million cubic meters of LNG from ORLEN,” said Roman Chumak.
The company is attracting international financing and upgrading its generation assets. An additional 177 MW of backup capacity has been secured to supply over 500,000 Ukrainians. This capacity will be operational this year to meet the population’s needs.
In the first quarter, Naftogaz secured around EUR 430 million from the EBRD and the Government of Norway, which will soon be used to purchase 1 billion cubic meters of imported gas. The company is also in talks with the Government and international financial institutions to raise an additional EUR 1 billion to buy over 2 billion cubic meters of gas,” said Naftogaz’s Acting CEO.
Roman Chumak noted that preparations for the next winter will not be easy. This will require coordinated efforts from all branches of government, engagement of international partners, and effective decision-making within the Naftogaz Group.
Last winter, Naftogaz Group achieved the impossible by keeping the heating season running despite all the challenges. Next winter, we need to do more than the impossible. We are getting ready,” he said.
