/// Critical_Issues

Why businesses lose money

Electricity makes up 15-40% of the cost of industrial products. Tariffs are rising, the grid is unstable, and non-storage generation is only 30% used.

Increase in tariffs

Power bills for factories are increasing by 20-35% annually. Peak rates are 3 times higher than night rates. Every hour of downtime is worth thousands.

Network dependency

Blackouts and restrictions from DTEK/Oblenergo halt production lines. The diesel generator cannot cope with the continuous load.

Solar generation losses

A SES without storage uses only 25-35% of the generated energy. The rest goes to the network at a minimum price or simply merges.

Changes in the green tariff

The green tariff for new facilities is reduced. The bet on selling to the network no longer gives an acceptable ROI without self-consumption.

/// Solar_BESS_Solution

SES + BESS: Complete Energy Independence

The Solar + Storage hybrid system transforms solar energy from an unstable source into a manageable asset. Generate, store, use on the most profitable schedule.

80% self-consumption

BESS stores excess daytime generation and releases it during peak hours and at night. Self-consumption increases from 30% to 80%.

Peak Shaving in the afternoon

SES covers the base load, BESS cuts peaks. Savings on the power tariff up to 40% every month.

Energy for the night shift

The energy accumulated during the day feeds the night production. Complete independence from tariff peaks. Arbitration day/night.

/// FAQ

Frequently Asked Questions

The typical payback of SES of integrated BESS is 3-4 years with self-consumption 80%. Without a storage device — 5-7 years. Key factors: electricity tariff, level of insolation (1100-1250 kWh/kW per year in Ukraine), and share of self-consumption. BESS allows you to use energy during peak hours, when the tariff is maximum, which significantly accelerates the return on investment.

Yes, legal entities can receive a green tariff for SPPs with a capacity of up to 150 kW (for rooftop facilities) or more, subject to participation in the auction. For capacities from 150 kW to 1 MW, the NCRECP auction mechanisms operate. At the same time, the strategy self-consumption + BESS often more profitable than pure sale to the network, because you save on the retail tariff, and not sell on the green.

For a land-based SPP with a capacity of 1 MW, approx 1.5-2 hectares territory On a flat roof - about 6000-8000 m² of usable area (taking into account the slope and passages). Modern modules of 580-610 W have a higher specific power, which allows you to place more kilowatts on the same area. BESS requires an additional 20-40 m² per container.

Yes, but there are nuances. Needed long-term lease agreement (minimum 10-15 years) of the right to install engineering systems. An alternative is the PPA model (Power Purchase Agreement), where the investor installs a CHP at your facility, and you buy electricity at a fixed price below the market price. The BESS container can be dismantled and moved to another facility.

BESS solves the main problem of solar generation — discrepancy between peak generation and peak consumption. Without storage, the SES generates a maximum at 12:00-2:00 p.m., and the enterprise also needs energy in the evening. BESS stores the surplus and gives it away when needed. In addition: peak shaving reduces the payment for power, arbitrage provides income from the difference in day/night tariffs, and backup power protects against blackouts. AI-EMS optimizes all flows automatically.
