BESS

CP200L

Our Battery Energy Storage Systems (BESS) ensure reliable, zero-emission and cost-effective power supply. They store electricity from renewable sources such as photovoltaics or wind, smooth fluctuations, and deliver energy exactly when it’s needed.

With state-of-the-art lithium iron phosphate (LFP) technology, liquid cooling, integrated Energy Management System (EMS), and advanced fire protection, G33 BESS are the ideal solution for industry, commerce, districts, and off-grid applications.

At the heart of our battery storage solutions is the CP200L single module. It combines a compact design with high power density and serves as a scalable base for industrial, commercial, and infrastructure use.

BESS single module with 215 kWh

The CP200L can operate as a standalone unit or be combined into larger systems—flexibly scalable to your energy demand.

Peak Shaving

Cut demand peaks—reduce electricity costs effectively.

Peak shaving means identifying and purposefully capping spikes in power consumption.

Many operations experience short periods of sharply increased demand—e.g., when machines start up simultaneously or EV charging infrastructure is in use. These peaks drive up network charges, as grid operators base their fees on maximum demand.

A Battery Energy Storage System (BESS) charges at low load times from the grid or from renewables such as PV. When a demand peak occurs, the BESS responds within milliseconds and provides the additional power. Grid load remains steady—the peaks are shaved.

Benefits:

• Cost reduction: lower demand charges and network fees

• Grid relief: more stable load without extreme fluctuations

• Efficiency: optimal use of self-generated power

• Planning certainty: consistent energy draw regardless of consumption patterns

FAQ

Information about BESS

Battery Energy Storage Systems (BESS)—also known as battery storage, industrial storage, or power storage—are key building blocks of a modern, sustainable energy system. They shave demand peaks, stabilize grids, enable efficient use of renewable energy, and ensure security of supply—from industrial large-scale consumers and district solutions to off-grid systems.

In this FAQ section, we answer the most important questions about the design, technology, and benefits of our energy storage solutions. You’ll learn which battery technology we use, how our systems are dimensioned, which standards and safety norms are met, and how long a BESS lasts in practice. We also explain available operating modes—from grid-parallel operation and peak shaving to self-consumption optimization, grid balancing, and backup power with black start capability.

BESS in practice

Versatile applications. Tailored to every need.

Use cases
