Green energy – available exactly when it is needed
Battery storage – the third pillar of the energy transition
Renewables are the backbone of the energy transition, but wind and solar energy do not align with our electricity demand. Battery storage provide the flexibility we urgently need by storing excess energy and releasing it when needed. By doing so, battery storage systems form the third pillar of the energy transition, alongside wind power and photovoltaics.
Battery storage systems shift green energy to times when it is needed. This creates a more stable and lower electricity price balance between generation and consumption, without the need to curtail wind or solar power.
A battery storage system consists of several key components that work together in precise coordination
Battery Cells
Battery cells form the heart of the system. They store the electrical energy.
Cooling & Temperature Management
Precise temperature control protects the cells from both overheating and undercooling, ensuring a stable operation.
Battery Management System (BMS)
The BMS controls the battery cells and manages the charging and discharging processes to ensure balanced utilization of the storage modules.
Inverter
The inverter converts direct current (DC) electricity to alternating current (AC).
Transformer
To ensure that the generated electricity is fed into the grid in compliance with standards, transformers adjust it to the correct voltage level.
Communication & Energy Management
Operation is monitored and controlled via data loggers, routers, and remote access technology. These tools ensure optimal efficiency and seamless grid integration.
Technology
Lithium-ion batteries in detail
Our battery storage systems are based on modern lithium-ion technology, which is the established industry standard for large-scale storage. This technology is proven, mature, and considered low-risk. It offers high energy density, fast response times, and optimal efficiency.
Inside the battery, we use lithium iron phosphate (LFP) cells – a particularly safe, long-lasting, and thermally stable chemistry. LFP batteries are less prone to overheating or catching fire.
Our storage systems are modularly installed in containers, making them scalable and space-efficient for integration into existing infrastructure.
Advanced safety, fire protection, and monitoring systems ensure reliable and secure operation. All components are designed for durability, easy maintenance, and maximum efficiency.
Battery storage systems absorb electrical energy from the grid during periods of surplus, such as strong winds or high solar radiation. They release the energy when demand increases. This creates a flexible balance between electricity generation and consumption.
They shift green energy to periods of high demand, stabilize grid frequency, and provide essential services that were previously delivered by fossil fuel power plants.
A battery storage system has an operational lifespan of around 30 years. The battery cells typically last 10-15 years and can be replaced individually.
The output of a battery storage system is determined by two main factors: the available grid connection capacity and the local conditions.
Smaller systems typically offer an output of 10–20 MW with a capacity of 20–40 MWh – enough to cover the electricity needs of 25,000-50,000 households for around two hours. Larger systems can deliver 60–80 MW of power and store 120–140 MWh of energy.
Our projects are usually connected to the medium- and high-voltage grids through nearby substations. This setup allows for efficient grid integration with minimal technical effort.
Lithium-ion batteries are space-efficient, recyclable, and highly efficient. They respond very quickly to grid fluctuations and are ideal for grid-support. In addition, they are based on lithium iron phosphate (LFP). LFP batteries are more durable, contain fewer problematic materials, and are less prone to overheating.
Yes, the storage technology is considered a proven industry standard and is used in battery storage systems worldwide.
The risk of fire is practically nonexistent. Our systems meet the highest safety standards and are equipped with state-of-the-art fire protection and explosion prevention systems, as well as monitoring systems. We also collaborate closely with local fire departments and authorities to develop thorough fire safety plans. Qualified professionals regularly perform maintenance to ensure ongoing operational safety.
