The war in Ukraine has entered a new phase of strategic targeting, one that directly threatens the energy infrastructure underpinning Russia’s winter campaign. On Monday, Ukrainian forces launched precision strikes on fuel depots in occupied territories, including a major facility near Donetsk. British energy analysts now warn that these attacks could precipitate a severe supply shock for Russian forces and the occupied regions as temperatures drop.
Dr. Simon Fielding, a senior analyst at the Oxford Institute for Energy Studies, described the strikes as ‘a calculated attempt to degrade Russia’s logistical backbone’. The targeted depots store diesel, petrol and aviation fuel essential for military operations. With winter approaching, the loss of stored fuel compounds existing difficulties in supply chains already strained by sanctions and sabotage.
‘We are looking at a 15 to 20 per cent reduction in available fuel volumes for the occupied territories within the next four weeks,’ Fielding estimated. ‘This is not a minor disruption. It is a systemic blow to Russia’s ability to sustain mechanised warfare and keep its civilian population warm.’
Ukraine’s strategy mirrors the attritional logic that has defined this conflict: targeted strikes on infrastructure impose asymmetric costs. Russia, possessing larger resources, must now divert efforts to protect and replenish fuel dumps, while Ukraine conserves its own supplies by striking from range. The result is an energy war within a ground war, with each side calculating winter reserves as carefully as ammunition stockpiles.
From a climatological perspective, the timing matters. The Northern Hemisphere is entering its coldest months. In occupied Ukraine, average January temperatures hover around -5°C, but wind chill and snow can push effective cold exposure far lower. Fuel is not only a military requirement but a survival necessity for hospitals, schools and households. Depriving Russian forces of fuel also means depriving the civilian populations they claim to protect.
‘Energy is the currency of modern warfare, and Ukraine is attacking the central bank,’ said Dr. Fielding. ‘If the depots cannot be restocked quickly, the consequences will cascade through every facet of the occupation – from truck convoys to electricity generators to heating boilers.’
The International Energy Agency has monitored a steady decline in Russian fuel production since March, partly due to sanctions and partly due to Ukrainian attacks on refineries. The latest strikes on depots are closer to the front lines, making replacement routes more vulnerable. British defence intelligence noted that satellite imagery shows heavy activity at alternative storage sites, suggesting Russia is scrambling to redistribute limited stocks.
However, there are risks for Ukraine as well. Each strike deepens the environmental damage on occupied land, with leaking fuel contaminating soil and water. Moreover, Russia may retaliate by targeting Ukraine’s own energy infrastructure more aggressively. Last winter, Russian missiles crippled Ukrainian power grids, leading to rolling blackouts. This year, both sides have learned from those campaigns.
‘We are in a stalemate of attrition, but energy is the variable that could tip it,’ Fielding concluded. ‘If Ukraine can sustain this interdiction campaign, the Russian logistical network will crack. If Russia can protect its depots and find new supply lines, the front line stays frozen. Either way, civilians will pay the price.’
As the cold tightens its grip, the hidden battlefield of fuel depots and pipelines will become as decisive as the trenches. For now, the trendline is clear: Ukraine is winning the energy war within the war, and the coming months will reveal whether it is enough.
