Imports already show how households voted
Customs statistics settle the argument before any price list is opened. In January–September 2026 Ukraine imported generator sets and rotary converters worth $707.9 million, 41.4% less than a year earlier, according to State Customs Service figures reported by Interfax-Ukraine on 13 October. Over the same period imports of electric accumulators rose 3.5 times to $3.18 billion, with 90.9% of that volume arriving from China.
Two mechanics explain the swing. A battery functions inside an apartment, where a combustion engine normally cannot be operated at all, and topping it up from the grid costs a fraction of a litre of petrol. The country has shifted from fuel-based backup to stored electricity in a single procurement cycle.
What the operators ordered this week
On Tuesday 13 October Ukrenergo introduced hourly outage schedules for all consumer categories from 06:00 to 23:59, covering 0.5 to 2 queues, alongside power limitation schedules for industry and business. Two days earlier, on Sunday 11 October, an emergency outage cut supply to the city of Rivne and parts of the Rivne and Dubno districts, as reported by the head of the Rivne regional military administration.
The capital now works differently. DTEK has abandoned the queue and sub-queue structure in Kyiv: stabilisation outages follow a personal schedule calculated for each address, per the company's explanation published by Minfin on 12 October. Adjacent buildings may receive different windows, checked by street and house number on the DTEK website, its Telegram and Viber bots or the Kyiv Digital app. DTEK describes the result as a "daily guideline" that new Ukrenergo commands or fresh damage can override.
Outside Kyiv, UNIAN's survey of regional operators for 13 October listed Kyiv region (DTEK) with outages across all queues lasting 3 to 8 hours a day; Kharkiv region with 2 to 6.5 hours depending on the sub-queue; Cherkasy region with 4 to 6 hours in two-hour blocks between 06:00 and 24:00; and Sumy region with 2 to 6 hours by queue.
The season ahead remains unmapped. Volodymyr Omelchenko, director of energy programmes at the Razumkov Centre, said on 13 October that up to 5 GW of generating capacity had been restored during winter preparations, but the constraint sits in high-voltage lines and substations. Outages of "16, 20 hours, maybe five days — nobody knows", he told UNIAN.
Shelf prices on 13 October
Retail tags move daily, yet the spread is instructive. A 2.5 kW Konner&Sohnen KS 2900 petrol generator was listed at UAH 17,199 on Epicentr, while a 3 kW Karcher PGG 3/1 reached UAH 27,999. Inverter models with output clean enough for electronics cost more: PRAMAC PMi3000 at 2.8 kW for UAH 29,990 and NIK IG4300i at 3.2 kW for UAH 27,000.
Portable storage of roughly 1 kWh clusters higher. The EcoFlow DELTA 3 Plus, 1,024 Wh, 1,800 W, LiFePO4 and rated for 4,000 cycles, sold at UAH 49,999 from Allo directly, with marketplace offers from UAH 39,789. The EcoFlow DELTA 3 stood at UAH 44,999 and the BLUETTI Elite 100 V2 at 1,024 Wh at UAH 43,500 on Epicentr. A 2,048 Wh EcoFlow DELTA 3 Max Plus was UAH 87,999 on Allo.
For fixed installations, a Deye 6 kW hybrid inverter bundled with a Deye SE-F5 Pro-C 5.12 kWh LiFePO4 battery was priced at UAH 105,395 on Epicentr before installation. Bought separately, the battery was UAH 45,999 and the inverter UAH 49,500.
Petrol at UAH 89.36 against the grid at UAH 4.32
Fuel dominates the economics of any engine. Using the 12 October national average of UAH 89.36 per litre of A-95, published by Minfin from A-95 Consulting Group data, the KS 2900 specification of 1.6 litres per hour at full load and 0.8 litres per kWh translates into UAH 143 per hour, roughly UAH 71.5 per kWh produced in the best case, and UAH 1,340 to fill the 15-litre tank. Light loads push the figure per useful kWh higher still.
Stored electricity is charged at the household tariff of UAH 4.32 per kWh, unchanged since 1 June 2024. With about 10% charging losses, that is near UAH 4.80 per stored kWh — some fifteen times below petrol.
Hardware changes the ranking
Running cost alone flatters batteries. Modelling a winter of 150 outage days, with the generator supplying 2 kWh a day (300 kWh), the 1 kWh station one full cycle a day (about 0.92 kWh usable, 138 kWh) and the 5.12 kWh kit one cycle a day (about 4.6 kWh usable, 690 kWh), produces the following.
| Option | Purchase price | Winter output | One winter | Three winters |
|---|---|---|---|---|
| KS 2900 generator | UAH 17,199 | 300 kWh | UAH 129 per kWh | fuel floor UAH 71.5 |
| EcoFlow DELTA 3 Plus | UAH 49,999 | 138 kWh | UAH 367 per kWh | UAH 126 per kWh |
| Deye 6 kW + 5.12 kWh | UAH 105,395 | 690 kWh | — | UAH 56 per kWh |
Across a single winter the small station delivers the most expensive energy, because UAH 49,999 is amortised over only 138 kWh. Stretched over its full rated 4,000 cycles, the same unit would approach roughly UAH 18 per kWh. The generator never escapes its fuel bill; the home kit wins over three winters precisely because it is worked harder.
Flat and house need different answers
Nothing here repays itself against grid power at UAH 4.32 per kWh. The return is measured in avoided damage: lost working hours, spoiled food, a gas boiler idled by a dead circulation pump. Sizing, not investing, is the task.
In a flat, safe generator operation is usually impossible, leaving a 1–2 kWh station to carry a router, laptop, lights and phones through a 4–6 hour window. Over three winters a UAH 49,999 unit works out near UAH 17,300 per winter including charging, and it will not run a cooker or heater.
A house can place an engine outdoors and must protect heating and well pumps. Over three winters at 2 kWh a day, the UAH 17,199 generator costs about UAH 27,200 per winter, mostly fuel. A Deye-class inverter with 5.12 kWh of storage costs roughly UAH 38,400 per winter before installation, switches automatically and can later accept a generator or solar panels. In analyst Ruslan Averin's view, a household facing 16-hour outages needs both devices: storage for the scheduled day, an engine for multi-day blackouts.
Credit exists, grants have stalled
Terms reported by Ekonomichna Pravda on 17 March 2026 allow owners of private houses and townhouses to borrow up to UAH 480,000 for up to 10 years for a generator, a generator with storage, or a package including solar panels, with the rate starting at zero in year one. The state writes off part of the principal once: 20% for a generator, 25% with storage, 30% for the full solar package. Individual flats are excluded and banks cap house area at 250–300 square metres. Condominium associations may borrow up to UAH 3 million for generators, solar plants or heat pumps.
Grant support is thinner. The Energy Efficiency Fund suspended new Energodim applications on 22 April 2026 to align the programme with EU Ukraine Facility rules, with no restart date announced as of late August. Frontline communities retain access to one-off winter support of UAH 19,400 — approximately the cost of an entry-level generator, and, as Ruslan Averin notes, far short of a storage system.
