Industrial Battery Storage for Kryvyi Rih: From Grid Survey to Commissioning

Step 1: What to Measure On-Site

Start with a load profile. For a 10 MW ore processing plant, you'll need 15-minute interval data for at least a full week. Without that, any capacity figure is rough. We measure at 0.4 kV, 6 kV, and 10 kV busbars, depending on your transformer layout.

Check power quality: voltage dips from quarry equipment, harmonics from variable frequency drives. These affect BMS and EMS settings. Also measure ambient temperature inside your electrical rooms — LiFePO4 cells derate above 35°C.

Step 2: Documents to Pull

Gather your current TU from DTEK Dnipro Electric Grids. That document specifies your permitted connection capacity, voltage level, and protection requirements. Also pull single-line diagrams, load schedules, and your energy bills for the last 12 months.

If you have a demand charge in UAH/kW, we need that tariff structure. If you're on a two-zone tariff, we need the time-of-use rates. Without these, payback calculations are fiction.

Step 3: Grid Constraints to Verify

DTEK Dnipro Electric Grids will review your connection application. They check if your BESS can export to the grid or if it's behind-the-meter only. In Kryvyi Rih, most industrial sites are behind-the-meter, so we size for peak shaving and backup, not arbitrage.

At 0.4 kV, you're limited to ~250 kW per feeder. For larger systems, you'll need a 6 kV or 10 kV connection. Verify transformer spare capacity — a 1 MW BESS can overload a 630 kVA transformer if not properly integrated.

Step 4: The Solution, Sized to Your Site

We design containerized BESS from 50 kW to 5 MW. For a typical 3 MW load with 1-hour peak, a 1 MW / 1.5 MWh system (LiFePO4, CATL cells) gives you 2 hours of backup. With liquid cooling and IP55/C4 outdoor cabinets, it can sit next to your existing substation.

Our EMS/SCADA integrates with your existing PLCs. You'll see state of charge, power output, and savings in UAH/kWm. We handle everything: audit, design, supply, installation, commissioning, and service from Kyiv.

We are not official distributors of any brand. We source Tier-1 cells and build systems that meet DTEK's technical requirements.

Step 5: What We Don't Do

We don't do residential storage. For home systems, contact SolarProm.com.ua. We also don't promise savings without data. If your load profile doesn't show a clear peak, we will tell you that BESS may not pay back.

But if your demand charges are high and you have frequent voltage dips from quarry equipment, a BESS is a solid investment. We can provide a feasibility study with real numbers from your site.
