Industrial Battery Energy Storage for Cherkasy and Cherkasy Oblast

Normal Working Day: Smoothing Peaks and Saving on Demand Charges

At 07:50, your nitrogen fertiliser plant starts its compressors. The load jumps from 1.2 MW to 2.1 MW in 15 seconds. Without storage, you pay the demand charge for that 2.1 MW peak for the whole month. With a 1 MW / 2 MWh BESS, the system discharges at 0.9 MW for 20 minutes, shaving the peak to 1.2 MW. At current commercial tariffs in Cherkasy Oblast, that saves roughly 180,000 UAH per month, depending on your load profile — payback in 4–5 years.

For a grain elevator, the pattern is different: you have seasonal peaks during harvest (August–October). The BESS charges at night (at a lower tariff) and discharges during the day when your dryers run. At 0.4 kV this works only for loads up to 150 kW; above that, you need a 10 kV connection. We design the system based on your actual load curve — without that, any payback figure is rough.

Cherkasyoblenergo approves the connection under local technical conditions (TU). We prepare the package, including the single-line diagram and protection settings, so you get TU without delays. The BESS is installed in an IP55/C4 outdoor cabinet or a 20/40 ft container, with liquid cooling and a BMS that balances cells to ±2% SOC.

Emergency Outage: Keeping Critical Loads Alive

At 14:23, a 110 kV line fault near Cherkasy causes a 2-second voltage dip, then a 40-minute outage. Your food processing line has a cold storage with 3,000 kg of dairy product. Without backup, you lose the batch — direct loss of about 250,000 UAH. A BESS with a fast transfer switch (under 20 ms) keeps the cold storage and control systems running. For a 200 kW load, a 500 kWh battery gives 2.5 hours of ride-through. That's enough to complete a controlled shutdown or start a diesel generator.

For a nitrogen fertiliser plant, the critical load is different: you need to keep the ammonia synthesis loop circulating to avoid catalyst damage. That requires 350 kW for at least 1 hour. A 500 kW / 1 MWh BESS covers that, and it also provides black-start capability for the plant's own CHP.

During grid restoration, the BESS synchronises automatically, so you don't get a second dip. Cherkasyoblenergo's dispatcher sees the storage as a controllable resource — you can even sell frequency regulation (FCR) later, but that's a separate project.

Seasonal Peak: Winter Evenings and Summer Heat

In Cherkasy, the grid peaks on cold winter evenings (17:00–21:00) when electric heating and lighting load jumps. Your food processing plant runs at full capacity to meet New Year orders. The grid voltage at your 10 kV substation drops to 9.2 kV — below the 10 kV +/−5% tolerance. Your motors draw 8% more current, overheating. A 1 MVA BESS with reactive power control (Q(U) mode) injects 300 kvar, raising the voltage to 9.8 kV. Without storage, you'd have to reduce production by 10% or pay for a new transformer.

In summer, the peak shifts to 11:00–16:00 due to air conditioning and irrigation. For a grain elevator, this coincides with grain drying. The BESS charges at night (night tariff is 50% lower) and discharges during the peak, saving on energy cost and avoiding demand charges. Over a 6-month season, that's about 1.2 million UAH savings for a 1 MW / 2 MWh system.

We model these scenarios in the feasibility study using your actual 15-minute load profile from Cherkasyoblenergo. That's why our payback estimates are within ±15% — not a marketing promise.

Technical Requirements and Connection with Cherkasyoblenergo

Any BESS above 50 kW must be approved by the distribution system operator, Cherkasyoblenergo. The connection is issued as technical conditions (TU) under the current grid code. You need: a single-line diagram, a protection coordination study, and a certified metering scheme (0.5S class at 10 kV). We handle all of that as part of the EPC contract.

For our typical Cherkasy projects, we use LiFePO4 cells from CATL or other Tier-1 manufacturers. The battery is liquid-cooled, which extends cycle life to 6,000 cycles at 80% depth of discharge — that's 15 years of daily cycling. The cabinets are IP55, corrosion class C4 (important for chemical plants with aggressive atmospheres).

We are not an official distributor of any brand, but we supply equipment from authorised channels, so you get full warranty. Our contract covers: audit, design, supply, installation, commissioning, and a 2-year service package. We install at 0.4 kV for small units (50–500 kW) and at 10 kV for larger ones — that's the standard voltage class in Cherkasy industrial zones.

Costs and Payback: What You Can Expect in Cherkasy

Turnkey cost for a 1 MW / 2 MWh BESS in Cherkasy is about 18–22 million UAH (including design, TU approval, installation, and commissioning). With demand charge reduction and energy arbitrage, the payback is 4–6 years. For a 500 kW / 1 MWh system, the cost is 10–13 million UAH, payback 5–7 years. These figures assume a load factor of 70% and a two-zone tariff (day/night).

If you also apply for the Ukrainian government's energy efficiency grant (up to 20% of cost), payback drops to 3–5 years. We have the paperwork ready for that application.

• 50 kW / 100 kWh: from 1.8 million UAH (0.4 kV connection)
• 200 kW / 400 kWh: from 4.5 million UAH (0.4 kV, possible 10 kV)
• 1 MW / 2 MWh: from 18 million UAH (10 kV connection)
• 5 MW / 10 MWh: from 85 million UAH (10/35 kV connection)

Without a load profile from Cherkasyoblenergo, we cannot guarantee these numbers. That's why the first step is a free audit — we measure your load for 2–4 weeks.
