Ukraine Spent $1.9 Billion on Gas Imports as Russian Strikes Cut Domestic Production
Montel's wartime grid analysis shows Ukraine's nuclear base held through four years of strikes, while destroyed thermal capacity and halved gas production drove a $1.9 billion import bill.
Montel's senior energy consultant Hubert Put concluded in an analysis published Tuesday (2026-07-29) that Ukraine has sustained electricity supply through more than four years of Russian infrastructure attacks, and that the tactical lessons now interest European grid planners directly. Montel treated the country as one of energy's more concrete stress tests: a grid forced to manage reliability under sustained aerial bombardment.4
Nuclear generates approximately 60% of Ukraine's electricity, with the balance split between hydropower and thermal plants burning coal or gas, according to The Economist. Reactors at operating plants have kept running throughout the conflict. That concentration in generation that has proven hard to physically destroy has been Ukraine's most durable backstop against supply collapse.1
But the thermal and gas side tells a harder story. In a three-week period described by The Economist in May 2026 (2026-05-19), Russian strikes took offline several thermal power plants and cut roughly half of Ukraine's domestic gas production. To replace that lost output, Ukraine spent $1.9 billion on imported gas, a direct fiscal drain on a country already stretched by wartime spending.1
Russia's turn toward energy infrastructure came as its ground campaign stalled. Putin's forces lost hundreds of thousands of soldiers for less than 1% of Ukrainian territory, The Economist reported in May 2026 (2026-05-19). That arithmetic shifted priorities. With territorial advance producing little return, attacks on electricity generation and gas production became a secondary lever aimed at civilian endurance rather than battlefield position.1
The Zaporizhzhia nuclear plant presented the sharpest individual risk. By early October 2025 (2025-10-01), The Independent reported the facility was experiencing its longest external power outage since the war began, a condition analysts described as "critical." Nuclear plants need uninterrupted external electricity to run cooling systems; prolonged outages carry safety consequences regardless of whether reactors are generating. Zaporizhzhia remains under Russian military control.3
Ukraine's grid was not starting from a fragile base. By 1990, Soviet Ukraine was generating approximately 300 billion kilowatt-hours annually, one of the largest national outputs in Europe, and supplying the bulk of the Soviet Union's electricity exports to the continent, according to the Atlantic Council. The wartime system European planners are now examining was built on that inherited infrastructure.2
Lana Zerkal, a member of Ukraine's Facility Platform Coordination Council, argued in a May 2026 (2026-05-28) Atlantic Council essay that Ukraine's wartime grid practices, including emergency load balancing, rapid repair protocols and cross-border synchronisation with the European network, hold operational knowledge that European system operators have not had to develop under comparable pressure.2
European gas prices have climbed through the summer. ICE Endex TTF front-month stood at €59.05/MWh in Saturday morning (2026-08-01) session data, with THE M+1 at €59.52/MWh. Further escalation in Ukrainian infrastructure attacks that disrupts cross-border electricity links or transit gas flows would add pressure to a market already running with limited seasonal headroom.
Winter is the harder test. Thermal capacity destroyed by Russian strikes cannot be rebuilt quickly, and Ukraine enters the cooling season with roughly half of domestic gas production disrupted and $1.9 billion in imports already booked. Russian attack patterns on Ukrainian energy infrastructure have shown no sign of easing ahead of peak heating demand.1
