Ukraine is preparing for another heating season with thermal generation destroyed, a gas deficit, and distribution networks that were worn before the war and have been repaired under fire since. The government has allocated tens of billions of hryvnia for winter preparation. Specialists warn that funding, staffing and the risk of new strikes leave the picture unresolved.
For anyone modelling the Ukrainian economy, this is not a humanitarian footnote. It is the primary variable.
Why the winter sets the growth rate
| Indicator | Reading |
|---|---|
| Q1 2026 GDP | −0.5% year on year |
| Primary cause | strikes on energy infrastructure, electricity shortages |
| NBU growth forecast, 2026 | 1.8% |
| Independent estimates | around 1% |
| Expected growth, 2027–2028 | 2.8–3.7%, conditional on energy restoration |
The first quarter of 2026 contracted, and the reason given was electricity. That is the cleanest available demonstration of the mechanism: when power is unavailable, output does not shift or slow, it stops. Factories cannot run, cold chains fail, service businesses close early, and remote work — the adaptation that carried the IT sector — requires both electricity and connectivity.
The gap between the National Bank's 1.8% forecast and independent estimates near 1% is almost entirely an assumption about how many hours of power the grid delivers between November and March.
The three constraints
Generation. Three years of systematic strikes have removed thermal capacity that took decades to build and cannot be replaced in a season. What remains is patched, and each repair cycle is more difficult than the last as spare equipment is exhausted.
Gas. A deficit means imports, and imports mean foreign currency at a time when every dollar is allocated. Gas purchased for the winter competes directly with other claims on the same reserves.
Networks. Distribution infrastructure is critically worn. This is the least visible constraint and in some respects the most limiting — generation restored upstream is of no use if the network downstream cannot carry it.
The second-order costs
The economic damage from a difficult winter does not stop at lost output.
Businesses that invest in generators and fuel are spending capital on redundancy rather than on capacity. That expenditure appears in the accounts as investment while producing no growth in productive capability — it buys continuity, not expansion.
Fuel demand for backup generation feeds directly into the inflation problem, where fuel was already the fastest-rising category and contributed roughly 0.7 percentage points to the headline rate. A bad winter therefore pushes prices as well as suppressing output — the combination that forced the National Bank to raise rates to 15.5% in July.
And population movement responds to heat and light. A winter without either accelerates emigration, which shrinks the labour force, which raises wages and reduces the tax base — a chain that outlasts the season that started it.
What to watch
Reserve accumulation ahead of November: gas in storage, coal stocks, and imported equipment for network repair. These are measurable now and they determine the range of outcomes later.
The second indicator is import capacity from EU grids. Interconnection has been expanded significantly, and cross-border supply is the buffer that converts a catastrophic winter into a merely difficult one.
Bottom line
The heating season decides whether 2026 delivers stabilisation or a repeat of the first quarter, and whether the 2.8–3.7% recovery projected for 2027–2028 starts on schedule. It matters more than any monetary or fiscal decision taken this year, and the preparations being made now set the boundaries of what is possible.
