Industrial Battery Storage for Zhytomyr: Cut Costs, Secure Power

What breaks your budget first in Zhytomyr Oblast

You know the drill: peak demand charges from Zhytomyroblenergo hit at 8:00–11:00 and 17:00–20:00. For a granite quarry, the crusher motors pull 2–3 MW for minutes at a time. For a dairy, pasteurizers and cooling compressors spike exactly when the grid is stressed. Woodworking shops face voltage dips that reset CNC controls — that is scrap and rework.

Uninterruptible power supplies (UPS) only cover seconds. Diesel generators cover hours but cost fuel and maintenance. Neither saves you money on the energy bill — they just keep the lights on.

The real cost is the demand charge and the time-of-use tariff. Without storage, you pay for peak power even if you could shift it. And when the grid goes down, you lose production.

How BESS closes the gap: peak shaving and backup

A battery system charges at night when electricity is cheap (or from your own solar if you have it) and discharges during peak hours. That shaves your demand charge by 30–50% — the exact figure depends on your load profile, which we measure on site before we design anything.

At 0.4 kV, a 100 kW battery can handle a small woodworking shop. For a quarry with 10 kV feeders, we install containerized systems at 10 kV or 35 kV. The connection is approved under local technical conditions (TU) issued by Zhytomyroblenergo — we handle the whole application process.

In case of a blackout, the storage system can island your critical loads — compressors, pumps, control systems — for 2 to 4 hours, depending on capacity. That is enough to finish a batch or shut down safely.

Numbers that matter: what you get and what it costs

For a 500 kW / 1 MWh system — typical for a medium dairy — expect to cut peak demand by 400 kW. At an average demand charge of 300 UAH/kW per month, that is 120,000 UAH per month, or 1.44 million UAH per year. System cost, installed, is around 8–10 million UAH. Payback: 5–7 years, assuming a tariff increase of 10% per year.

For a granite quarry with a 2 MW / 4 MWh system, the numbers scale up. We have seen payback in 4.5 years when the quarry runs two shifts and the peak window aligns with crushing.

These are rough figures until we analyze your 15-minute load data. We do that as part of the feasibility study, which we deliver within 3 weeks.

What we do and how we work with Zhytomyroblenergo

BESS Ukraine Engineering Group is a full-cycle EPC contractor. We audit your facility, design the system, supply equipment, install, commission, and service it for 10 years. We work with LiFePO4 cells from CATL and other Tier-1 manufacturers, with liquid cooling and a BMS that monitors every cell. The cabinets are IP55/C4 rated, outdoor-ready, and available in 20 or 40 ft containers.

We handle the technical connection: we prepare the application to Zhytomyroblenergo, negotiate the TU, and ensure the system meets their grid code requirements. We have done this for several sites in Ukraine — the process is standard but takes time, so we start it early.

We do not do residential systems. For home storage, contact SolarProm.com.ua.

Getting started: what the first step looks like

Call us at +380 44 339-50-20 or email engineering@bess.com.ua. We will ask for your last 12 months of electricity bills and your load profile from Zhytomyroblenergo. If you do not have the profile, we help you request it.

Within a week, we send you a preliminary assessment: system size, expected savings, and an estimated payback. If that looks interesting, we move to a detailed feasibility study and then to design and installation.

No obligation, no hard sell. Just engineering.
