Ukraine's Fifth Wartime Winter: The Combined Impact of Extreme Cold and Energy Infrastructure Attacks.

The Winter of 2025-2026 in Ukraine

According to Novyny.live: Ukraine is enduring its fifth winter under full-scale war conditions during the 2025-2026 season. The nation continues to face severe hardships, primarily due to relentless Russian attacks targeting its power grid. Since the start of 2025, the aggressor has launched more than 300 missiles and over 7,000 drones against Ukrainian energy facilities, inflicting serious consequences for the population and the economy. This sustained assault on critical infrastructure represents a core element of Russia's wartime strategy.

Russia has systematically targeted Ukraine's energy infrastructure since autumn 2022. Since the full-scale invasion began, substations operated by 'Ukrenergo' have been attacked more than 900 times.

On February 14, 2025, President Volodymyr Zelenskyy stated: 'There is not a single power plant in Ukraine that has not been damaged by Russian strikes.'

The State of the Energy Sector

Amid constant attacks and severe infrastructure damage, more than 15,000 energy sector workers have been mobilized to repair and restore grids and generation capacity. Despite these efforts, the situation remains critical. On October 30, 2025, Ukraine was forced to implement scheduled blackouts, a direct response to the growing strain on its power system as electricity production has fallen. The resilience of the energy workforce is being tested daily.

Compounding the crisis, the winter of 2025-2026 has been one of the coldest in recent Ukrainian history, with temperatures plunging to -25°C and, in rare instances, down to -30°C. This extreme cold has placed an additional burden on the already strained energy system, as each degree of frost demands significantly more power for heating homes and sustaining basic services for the population.

Despite all difficulties, the dedication of energy sector workers remains unwavering. However, any near-term improvement in the energy situation remains uncertain, with the future dependent on developments on the front lines and Ukraine's capacity to both restore and defend its critical energy infrastructure.

The circumstances in Ukraine during the 2025-2026 winter period illustrate not only the consequences of military action but also the enormous strain placed on the energy sector under sustained assault. Given that this is one of the most severe winters in years, the country's power system faces compounded challenges. Continued support from international partners, who can provide aid for restoring and modernizing energy infrastructure, remains crucial to ensuring stability amid the ongoing conflict.
