Electricity for Mining in Ukraine 2026: Tariffs, Night Metering and Solar

Electricity is the main cost in mining and the key factor in ASIC payback in Ukraine. The same model can be profitable on an industrial tariff and run at a loss on a residential one. Let's break down real 2026 tariffs, night metering, solar panels, and how to correctly calculate the cost of a kilowatt for mining.

What makes up the cost of mining

The formula is simple: net profit = coin revenue − electricity cost. Daily consumption is calculated as:

Cost = Power (kW) × 24 h × Tariff ($/kWh)

For example, the Antminer S21 (3550 W) at a 0.07 $/kWh tariff consumes about $5.96/day in electricity. On a residential tariff this figure grows 1.5–2×, which directly eats into profit.

Key nuance: mining on a residential tariff is formally commercial use of electricity, and at large loads this creates risks with the supplier. An industrial tariff in a mining hotel means both a lower price and a legal placement model.

Night (multi-zone) metering

A two-zone or three-zone meter delivers electricity nearly twice as cheap at night. For mining, that means part of the day the hardware runs at minimal cost. Two strategies:

• 24/7 mining — use a blended tariff (day + night), since switching ASICs off daily is bad for their lifespan.
• Night-only mining — some miners run only in the night zone when the kilowatt is cheapest. This lowers revenue but sharply improves margin on a residential tariff.

Solar panels and generators

A solar plant is attractive because during the day it provides an effectively free kilowatt once the panels pay off. But there are caveats:

• An ASIC needs stable 24/7 power, while the sun delivers energy only during the day and depends on weather.
• Only a "solar + grid" or "solar + battery" combo is economically justified — not standalone panel operation.
• A fuel generator is almost always more expensive than the grid — count it only as backup during outages, not as the primary source.

Before buying a plant for mining, calculate the cost per kilowatt including panel and inverter depreciation — often it's not 0 but 2–4 UAH/kWh.

How to lower the cost per kilowatt

1. Pick an efficient model. The lower the efficiency (J/TH), the less you pay for the same hashrate. Hydro flagships hit 9–13 J/TH vs 17+ on older air units — details in our ASIC cooling guide.
2. Tune the firmware to your tariff. Firmware and overclocking let you cut consumption in eco mode when the kilowatt is expensive.
3. Consider a mining hotel. An industrial tariff + cooling + monitoring often beats home mining — see the comparison in mining hotel vs home.

How to calculate payback correctly

Don't rely on "daily revenue" without the tariff — the most common beginner mistake. Factor in:

• your real tariff (blended day/night);
• rising network difficulty, which gradually lowers revenue;
• coin price volatility.

Plug your tariff into the profitability calculator — it computes revenue from live network data and shows payback in days.

Conclusion

In Ukraine in 2026, electricity cost decides everything. A residential tariff suits one or two machines and night mining; an industrial tariff in a mining hotel suits scaling. Solar panels only make sense in a hybrid setup. Before buying an ASIC, always calculate payback against your specific tariff, not the "market average".
