Energy independence tailored to your operation.

BESS – Battery Energy Storage System – is an industrial battery storage system that stores energy from your company’s solar PV system or electricity purchased when prices are favorable.

The stored energy is released exactly when your business needs it most. Your electricity bill thus becomes an active tool for reducing costs and generating revenue.

We design, supply and integrate complete solutions from renowned manufacturers – from smaller commercial systems to large-scale containerized storage systems.

  • Maximum use of solar energy without selling surplus energy back to the grid at unfavorable prices
  • Reduced reserved capacity and electricity demand charges
  • Peak shaving – limiting short-term demand peaks
  • Backup for critical infrastructure during a power grid outage
  • Participation in flexibility markets and provision of ancillary services
  • Fast charging for electric vehicles without major grid connection upgrades

One system. Multiple sources of savings and revenue.

kWh price optimization

Buy electricity during hours with low or even negative spot prices and use it during peak periods. EMS controls charging cycles in real time based on market forecasts.

Reduced reserved capacity

A lower contracted capacity means lower fixed payments to the distributor. BESS covers demand peaks without the need to increase contracted values.

Peak shaving

Eliminate 15-minute demand peaks, that would otherwise result in penalties and higher charges for uncontracted consumption.

Self-consumption of solar PV

Instead of selling surplus energy at unfavorable prices, store it and use it when your business actually needs it. The payback period of your PV system can be significantly shortened.

Backup during outages

Keep critical equipment running even during a grid outage. The switchover takes place within milliseconds.

Flexibility market

Participation in FCR, aFRR and mFRR ancillary services and trading platforms opens up a new source of revenue. The EMS manages everything automatically.

Phase and voltage balancing

Local grid stabilization, reactive power compensation and frequency control provide higher power quality for sensitive technologys.

Charging infrastructure enhancement

Expand EV fast-charging capacity without costly grid connection upgrades. BESS supplies peak power while the distribution grid remains unchanged.

Path to carbon neutrality

A higher share of renewable energy in consumption, measurable CO₂ emission reductions and ESG reporting. At the same time, you gain a competitive advantage in tenders and with investors.

One storage system. Many applications. Battery storage systems from tens of kW to megawatts. Scalable solutions from tens of kWh to multiple MWh.

BESS is not a single-purpose device. One system can perform several different functions throughout the day and maximize the economic return on investment according to current conditions.

Alternative to grid reinforcement

In suitable locations, battery storage can be a faster and less expensive alternative.

06 UPS / Backup

Critical operation backup

Data centers, manufacturing, logistics facilities or hospitals remain operational even during an outage.

07 Energy markets

Spot market and flexibility

Automated energy trading and provision of ancillary services using EMS.

Why businesses are investing in BESS right now.

Electricity prices are no longer constant. Energy is a dynamic market that rewards businesses capable of actively managing their energy. BESS allows electricity to be stored when it is inexpensive or when the business has surplus energy, and used exactly when it delivers the greatest value.

The business gains greater control over costs, reduces demand peaks and can also use battery storage for flexibility, operational backup or energy trading.

What businesses most often consider before investing in BESS.

Answers to key questions about payback, sizing, implementation, safety and operation of commercial battery storage.

What is the typical payback period for a commercial battery storage system?

The final payback period depends on the consumption profile, reserved capacity, tariff, PV operation and how the battery is used. For properly designed commercial systems, it typically ranges from approximately 3 to 6 years.

If the storage system simultaneously reduces demand peaks, increases PV self-consumption and responds to electricity prices, the payback period can fall below five years. We prepare a specific economic model based on your company’s actual data.

Can BESS be connected to an existing PV system?

Yes. In most cases, battery storage can also be added to an existing PV plant. An AC-coupled solution connects to the AC side of the installation, so there is often no need to replace the existing inverters.

With compatible technologys, a deeper integration with the PV system can also be designed. We determine the appropriate architecture based on the technology used, system configuration and required functions.

How are the required battery power and capacity determined?

Storage size cannot be determined correctly from annual consumption alone. During design, we evaluate primarily 15-minute consumption data, PV generation profile, contracted values with the distributor and the objectives of the project.

A system intended for peak shaving requires a different power-to-capacity ratio than one designed for backup or energy trading. For medium-sized businesses, solutions often range from approximately 50 to 500 kW of power and 100 to 1,000 kWh of capacity.

How long does BESS preparation and implementation take?

For smaller commercial systems up to approximately 200 kW, the period from contract signing to commissioning is typically 3 to 5 months. The largest part of the schedule usually consists of project preparation, permitting and the connection.

For large projects in the megawatt category, preparation takes longer and may require approximately 9 to 14 months. We handle the project documentation, communication with the distributor and required administration for you.

How is battery storage safety addressed?

Modern commercial systems predominantly use cells with LFP chemistry, which offers higher thermal stability than some older types of lithium-ion batteries.

Safety is addressed at several levels – from monitoring individual cells and battery modules to temperature management and protection and fire suppression systems. The solution can also include continuous remote monitoring and automatic response to abnormal operating conditions.

Can the battery generate revenue on the flexibility market?

Yes. In addition to managing self-consumption, a modern EMS can optimize electricity purchases and sales and prepare the system for participation in balancing services or other forms of aggregated flexibility.

Combining several applications of a single storage system is known as value stacking. The battery can therefore, at different times of the day, reduce costs, protect operations and simultaneously generate additional revenue.

Is funding available for commercial BESS projects?

Funding options vary depending on currently available support programs, company size, location and project purpose. Support may be available, for example, for energy savings, solar PV, energy storage or energy communities.

We review suitable programs for the specific project and assist with preparing the required documentation. The potential level of support must always be verified against the current conditions of the relevant program.
