Industrial Battery Energy Storage for Kharkiv: Pre-Design Survey Checklist

Step 1: Measure the Actual Load Profile

Start with a 15-minute interval load profile over at least one full week. For a machine-building plant or a food processing line, a single day is meaningless. You need the peaks, the valleys, and the morning ramp when compressors start.

If you have no recorded profile, we install temporary loggers on the main LV switchboard. For 0.4 kV connections, that is straightforward. At 10 kV, we work with the plant's relay protection engineer to avoid operational disruptions.

Step 2: Pull the Grid Documents and TU

Request from Kharkivoblenergo: the connection agreement, the issued technical conditions (TU), and the single-line diagram of the substation. The TU will specify the permitted power and the voltage level. Without the TU, no storage project is bankable.

Also pull the energy consumption contract and any reactive power penalties. In Ukraine, exceeding the agreed reactive energy limit costs real money – a battery with reactive power capability can reduce that.

Step 3: Verify Grid Constraints

Check if the local substation transformer can handle charging. At 0.4 kV, a 100 kW battery adds roughly 150 A per phase – often manageable. Above 500 kW, you should step up to 10 kV. At that level, Kharkivoblenergo's relay protection settings and short-circuit current values become critical.

Also check the voltage regulation: with a large industrial load, the battery's reactive power injection can improve voltage stability. But that requires a proper power factor control mode in the EMS.

Step 4: Define the Use Case and Size

For Kharkiv's industries – turbine manufacturing, electronics, food processing – the typical use cases are peak shaving, demand charge reduction, and backup power for critical processes. That means the battery size depends on your specific tariff structure and load profile.

Without a load profile, any kWh figure is rough. With a profile, we run a 15-minute interval simulation to find the optimal capacity. In this region, we see common sizes from 250 kW / 500 kWh to 2 MW / 4 MWh. Payback is usually 4–7 years, depending on the tariff and the spread between night and peak prices.

Step 5: The BESS Solution and EPC Contractor

Once the survey is complete, we design a system using LiFePO4 cells from CATL or other Tier-1 manufacturers. The cabinets are IP55/C4 rated, with liquid cooling and a BMS that monitors every cell. The EMS/SCADA integrates with your existing control system.

We are BESS Ukraine Engineering Group, a full-cycle EPC contractor based in Kyiv. We handle audit, design, supply, installation, commissioning, and service. We work with industrial storage from 50 kW to 5 MW. We do not do residential – for home batteries, see SolarProm.com.ua. Call +380 44 339-50-20 or write engineering@bess.com.ua.
