Battery Energy Storage for Manufacturing Plants in Bila Tserkva

Normal Working Day: Peak Shaving and Reactive Support

At 8:15 a.m., the plant's 500 kW extruder line kicks in. Without storage, the transformer sees a 700 kW spike for 40 seconds, and you pay demand charges for that peak all year. With a BESS, the EMS forecasts the load from the previous 14 days and discharges 250 kW during that window. The grid draw stays flat at 450 kW.

Because Bila Tserkva's industrial parks sit at the end of 10 kV feeders, voltage drops of 5–7% are common during motor starts. The BESS's inverter provides reactive power in less than 20 ms, keeping voltage within ±5%. That prevents contactor chatter and PLC resets that cost you 20 minutes of scrap each time.

At 0.4 kV, a BESS can handle most inrush currents if placed close to the load. For larger motors or longer feeders, we step up to 10 kV connection. That is where DTEK Kyiv Regional Grids requires a technical specification and a grid study — we handle that as part of the EPC scope.

Emergency Outage: Process Line Backup

DTEK Kyiv Regional Grids reports an average of 3–5 unscheduled outages per year in the Bila Tserkva area, each lasting 1–4 hours. For a pharmaceutical plant, losing the cold chain for 2 hours can ruin a batch worth 1.2 million UAH. A BESS with 2 hours of autonomy at your critical load keeps the line running.

We size the battery for 70% of your essential load — typically pumps, control systems, and lighting — not the whole factory. That keeps the battery cost down. The transfer switch isolates the BESS in island mode within 100 ms. Your process does not blink.

After the grid returns, the BESS recharges automatically. The EMS manages the rate to avoid a second peak when the grid stabilizes. Without that, you would hit a new demand peak and pay for it for 12 months.

Seasonal Peak: Winter and Summer Demand Spikes

In December, electric heating in the plant office and warehouse adds 150 kW to the base load. The local grid transformer is often overloaded, and DTEK may enforce curtailment. Your BESS can shave that extra peak, keeping your production unaffected.

In July, the agri-processing plants in Bila Tserkva run at full capacity, and the 10 kV feeder voltage sags. Your BESS's voltage support function becomes critical. We program the EMS to prioritise reactive power during those months, sacrificing a bit of energy capacity for voltage stability.

Seasonal sizing is not guesswork. We take your half-hour load data for the past 12 months, identify the top 10 demand days, and size the battery to cover the highest 2-hour window. If you do not have that data, we install a temporary meter for two weeks — that is part of the audit.

Why Bila Tserkva Factories Need This Specifically

Bila Tserkva is not Kyiv, where the grid is stronger. The city's industrial profile — rubber products, pharmaceuticals, agri-processing — means many simultaneous motor starts and sensitive processes. The local 10 kV network is aging, and DTEK Kyiv Regional Grids applies strict contracted capacity limits. Exceeding your limit even once triggers a penalty of up to 30% of your monthly bill.

The industrial park that hosts many factories has its own substation, but its transformer is shared. A BESS at your site reduces your draw, freeing capacity for your neighbors — that is a strong argument in negotiations with DTEK for a capacity increase without paying for grid upgrades.

Sizing for this combination must account for the motor start sequence. We ask for the list of the three largest motors, their start currents, and the acceptable dip in voltage. Without that, the BESS may be undersized and you will still see sags.

EPC Contractor: BESS Ukraine Engineering Group

We are BESS Ukraine Engineering Group, a full-cycle EPC contractor for industrial storage from 50 kW to 5 MW. We have delivered feasibility studies for factories in Kyiv Oblast, including Bila Tserkva. Our scope: audit, design, supply, installation, commissioning, and 24/7 service.

We use LiFePO4 cells from CATL and other Tier-1 suppliers, liquid cooling, BMS, EMS/SCADA, IP55/C4 outdoor cabinets, and 20/40 ft container solutions. We do not do residential systems — for those, contact SolarProm.com.ua.

Call +380 44 339-50-20 or email engineering@bess.com.ua. We will start with a load profile analysis and give you a realistic payback figure — typically 3.5 to 5 years with current DTEK tariffs.
