Energy system

Two national energy systems under the same strike campaign: Ukrainian generation and imports, and Russian refining — each attacked at the tier where it is most concentrated.

Context, not targeting. A system record names published markers and published operators and states dependencies at the level a published institution does. It carries no facility-level capacity, vulnerability, protection or repair detail; the schema has no field for any of it.

What this system is

Ukraine's grid lost roughly half its dispatchable generation in the first year of the war and runs on repair, European interconnection and imported fuel; Russia's refining tier, not its crude output, is what Ukrainian deep strike has reached since 2024, reaching Russian motorists as rationing in 2026.

Generation decides whether households have heat, light and pumped water in winter, whether industry including the defence industry can operate, and how much of the budget goes to imported electricity and repair. Refining decides whether Russian crude abundance becomes Russian product availability. The system is where the military, economic and humanitarian dimensions of the war become one subject.

The system

Overview
Ukraine entered the war with a generation mix dominated by nuclear, supported by hydro on the Dnipro and thermal plant, and a refining sector in long decline. On the IEA's figures available dispatchable generation was roughly 38 GW before 2022; occupation, destruction and damage removed about 19 GW in the first year; concentrated attacks in spring 2024 brought the figure to about 12 GW; some 3 GW was restored before the 2024/25 winter and repair has continued since. Synchronisation with the European grid in 2022 made imports a standing part of supply, and liquid fuel is now overwhelmingly imported through the western land corridors. The largest nuclear station, at Zaporizhzhia, has been under Russian control since 2022 with all six reactors shut since 2024. On the other side of the same system, Russia produces around nine million barrels of crude a day but reaches its own motorists only through refineries, and that tier — concentrated in the Volga and central regions, behind the Black Sea coast and in Siberia — has been the principal object of the Ukrainian deep-strike campaign since 2024, at increasing depth.
Current state · as of 2026-09-27
Strike tempo on the Ukrainian grid stayed active through September 2026 and the target set widened; Ukrenergo reported new outages in six regions after the attacks to 25 September. On the Russian side, refinery throughput fell to about 3.6 million barrels a day in July 2026 on commercial estimates, roughly a third below the seasonal norm; purchase limits returned at filling stations in the Moscow region in August; Reuters attributes the shortages to strikes, seasonal demand and unscheduled maintenance together, and the published data does not separate them.
Documented exposure
At the level the IEA and the IAEA publish: the capacity series above, the off-site power supply of the Zaporizhzhia station as a standing IAEA concern, and the refinery-throughput estimate carried by Bloomberg. No facility-level state is published here.

Nodes

The published markers that carry this system value, by the module’s own priority. A note is the system record’s; a marker without one is a member by its own tag.

Routes and operators

Supply systems running through it

  • Electricity generation and fuel supplyFuel imports · 7 nodes · 4 documented disruptions · named by the recordThe system that decides whether a country at war can be kept warm, lit and working — and the one being attacked for exactly that reason.
  • Crude refining and domestic fuel supplyFuel imports · 10 nodes · 2 documented disruptions · named by the recordThe tier between an oil producer and a working petrol station — and the one place in Russia's energy system where a shortage is possible at all.

Organisations that run it

  • RosneftEnergy company · ActiveRussia's largest state-controlled oil company, operator of several of the Volga refineries the module publishes as markers and a party to the refined-product shortfall of 2026.
  • Gazprom NeftEnergy company · ActiveThe Gazprom group's oil arm, operator of the Moscow, Omsk and Salavat refining complexes the module publishes as markers — one of them Russia's largest by throughput.
  • NaftogazState enterprise · ActiveUkraine's state oil and gas company, which imported several billion cubic metres of gas for the 2025–26 heating season after strikes on production and storage, financed externally.
  • UkrenergoInfrastructure operator · ActiveUkraine's transmission system operator, whose outage and restriction statements are the operator source the module reads for the state of the grid under strike.

Dependencies and constraints

Each marked documented (a published source states it) or assessed (Vigil infers it and says so). The two are never drawn the same way.

Depends onDocumented Confidence: High

European grid interconnection. The only fast-acting relief available to Ukrainian supply, and finite: firm import capacity was set at 2.1 GW for winter and 1.7 GW for summer as of December 2024, against a winter peak demand the IEA puts at 18 GW in 2023/24 and 16.5 GW in 2024/25. Imports are a margin, not a substitute.

LogisticsElectricity generation and fuel supply

Sources: IEA electricity and energy-security analysis

Depends onAssessed Confidence: Moderate

Transmission and a small number of nuclear sites. Three nuclear plants carry about half of Ukraine's generation capacity on the IEA's accounting — roughly 7.7 GW — which concentrates an unusual share of the system in few sites and in the transmission that connects them. The concentration is the exposure; nothing here says what state it is in.

ConstraintDocumented Confidence: High

Electricity cannot be stockpiled: generation lost is generation unavailable until repaired or replaced, and the long-lead components involved take many months to source.

What remains unknown

  • No clean published figure exists for the winter 2025/26 generation outcome; the record states so rather than interpolating one.
  • Which Russian facilities are currently degraded is not published by the module, by rule.

Readings the evidence also supports

  • Russian product shortages have three published causes — strikes, seasonal demand and unscheduled maintenance — and the data does not separate them.

Listed because the record's own assessment is not the only one its sources permit — not as a hedge on the assessment above.
