Battery storage for businesses

Battery storage for businesses

Energy, made smarter

Why battery storage systems make sense for businesses now

Volatile, and at times negative, electricity prices, along with increasing grid constraints, are making battery storage systems an increasingly attractive investment for businesses. Tailored battery storage solutions help companies manage their energy more intelligently and reduce electricity costs over the long term.

Whether deployed as a stand-alone battery storage system or combined with a solar PV installation (co-location), we design and deliver high-performance energy storage solutions tailored to your business needs.

Battery storage solutions

Applications at a glance

Self-consumption optimization

Excess solar energy is stored and used when needed, reducing grid charges, levies, and overall energy costs.

Reduce energy costs

Peak shaving

Peak shaving with commercial battery storage systems reduces costly demand peaks, helping lower demand charges and grid fees.

Reduce demand charges

Spot market arbitrage

Store when prices are low, sell when prices are high: Spot market arbitrage enables businesses to benefit from electricity price fluctuations.

Generate additional revenue

Charging infrastructure

A commercial battery storage system supplies charging stations with the required power, relieving grid connections and avoiding costly grid expansions.

Secure charging infrastructure

Multi-use strategies

Multi-use instead of standalone solutions: Combine self-consumption, peak shaving, and market participation into an economically optimized overall concept.

Use storage for multiple applications

Co-location and stand-alone


Battery storage systems for businesses can either be combined with an on-site photovoltaic system (co-location) or operated as standalone, grid-connected systems (stand-alone). Both options differ in their system architecture, areas of application, and economic potential.

The right solution for your business depends on your individual requirements, existing conditions, and economic objectives.

Frequently asked questions about battery storage systems

What you should know about battery storage systems for businesses

Battery storage systems are particularly beneficial for businesses looking to sustainably reduce energy costs and improve energy efficiency. Especially for companies with high electricity consumption, recurring peak loads, or their own photovoltaic system, battery storage systems play a key role in optimizing operational energy management.

In a co-location solution, the battery storage system is combined with a photovoltaic system and operated through a shared grid connection. A stand-alone system, on the other hand, operates independently of any renewable energy installation and is connected directly to the public electricity grid. This allows it to be used flexibly for applications such as energy arbitrage, balancing services, and other grid support services.

The process begins with a detailed analysis of your energy consumption data and load profiles. Based on these insights, the storage capacity, power rating, and operating strategy are tailored to your specific needs. We consider both the technical requirements and the economic potential of the solution.

In addition to storing excess solar energy, battery storage systems for businesses can reduce peak demand, optimize grid charges, support EV charging infrastructure, and capitalize on electricity market price fluctuations. With multi-use strategies, multiple applications can be combined to maximize economic value.

We continue to support your battery storage system even after commissioning. Through continuous monitoring, remote supervision, and regular performance analyses, we optimize the system performance and detect potential issues at an early stage.
