Ukraine's DTEK Says Country Better Placed for Winter After War Lessons
DTEK's head says wartime infrastructure adaptations leave Ukraine better placed for winter, even as high European gas prices curb import capacity ahead of the heating season.
Ukraine's largest private utility is more confident about the coming heating season than it was twelve months ago, despite an active conflict on its territory. Maxim Timchenko, chief executive of DTEK, told Montel late on Thursday (2026-06-25) that Ukraine had applied lessons from last winter's devastating Russian infrastructure strikes and is better positioned to withstand attacks this time around.6
Ukraine's power and gas systems remain a primary target of Moscow's long-range strikes. Last winter's attacks degraded generating capacity and left millions without heat for extended periods, forcing emergency imports from neighbouring countries and exposing the grid's vulnerability to sustained bombardment.3
Kyiv has set an official gas storage target of 14.6 billion cubic metres, or roughly 34% of the country's underground capacity, by the start of winter, with a floor of 13.2bcm — about 30% — described by Prime Minister Shmyhal as the minimum to ensure stable supply under wartime conditions.2
Reaching that floor is not straightforward. Ukraine's gas imports fell sharply in late May, dropping from 24 million cubic metres per day on Tuesday (2026-05-19) to 0.8mcm, the lowest level in more than a year, according to Kyiv-based consultancy ExPro. The cause was price: ICE Endex TTF front-month gas was trading at €41.21 on Friday (2026-06-26), making purchases expensive relative to domestic production and stored reserves.1
Ukraine halted the transit of Russian gas to Europe when the prewar transit agreement expired in early 2026, removing a longstanding revenue stream and cutting the remaining trickle of Russian volumes flowing westward. Before the war, Russia accounted for nearly 40% of the EU's pipeline gas supply; by 2023 that share had fallen to around 8%, according to EU Commission data, with the figure lower still by June 2026.4
The gas transmission system operator GTSOU has been pushing to expand and diversify import routes, with Slovakia and Poland the principal conduits, as a hedge against any single entry point being struck or cut off. Poland, which shares a border and has provided transit capacity as well as military support, features in the routing options under discussion.5
DTEK itself operates coal-fired and renewable generation assets across Ukraine and is directly exposed to grid instability whenever Russian strikes force emergency load-shedding. Timchenko's cautious optimism — "I am rather an optimist... we have all learned" — reflects changes to physical hardening and distributed generation backup rather than any reduction in the threat environment.6
The market implication for European gas runs through Ukrainian storage levels. Ukrainian underground caverns represent a large if legally separate slice of the continent's total reserve base, and a Ukrainian shortfall heading into winter would add to EU supply stress at a time when ICE Endex TTF front-month was already trading up 1.35% at €41.21 on Friday (2026-06-26). The 13.2bcm minimum target was calibrated for wartime disruption, but Kyiv's ability to reach even that floor depends on whether gas import costs ease enough through the summer injection window.2,4
Russian air-strike patterns typically intensify ahead of winter, and Ukraine's energy infrastructure has been a recurring target. Whether this winter's hardening measures prove adequate depends on both the scale of future attacks and the speed of repairs — the same open variables that shaped last winter's emergency and that DTEK's chief executive acknowledged have not disappeared, only been better prepared for.6,3
