The energy turnaround is one of the greatest challenges of our time. An important component of the energy transition is the use of renewable energies such as wind and solar power to reduce CO2 emissions. However, renewable energies are not always available when they are needed.

Unpredictable renewable power generation, increasing energy demand, and energy security concerns require greater local independence and resilience to centralized grid operations. By combining battery storage systems with distributed energy generators, we can find a path to energy self-sufficiency. Batteries will play an important role in energy distribution, enabling the energy transition.

Battery storage systems are an important pillar of the energy transition because they are decentralized, flexible, and cost-effective for building grid capacity, providing power on demand, and increasing the availability of renewable energy. The decentralisation of the energy system opens up new possibilities for cellular organisation and control of the grid, which will lead to smart energy ecosystems, new business as well as billing models throughout the energy industry.

Application scenarios

AXSOL’s Energy Container Solutions offer flexible application options that can be used individually or in combination. For example, they can store surplus energy and release it on demand to reduce peak loads and lower energy costs. At the same time, they can also help ensure an independent power supply and increase grid stability by balancing grid fluctuations and stabilizing grid frequency.

Self-consumption optimization

Self-consumption optimization aims at the optimal use of self-produced electricity, especially solar power, to reduce the need for expensive grid electricity.  Battery storage enables the storage of surplus solar power. With battery storage, solar power can be used outside of sunny hours, further increasing independence from the grid. In addition to solar, other power sources such as wind turbines, fuel cells, and fossil generators can be considered and integrated.


Peak shaving refers to the reduction of peak power demand by storing surplus energy during periods of low power demand and releasing it at times of high power demand. This reduces the power price for customers with an annual power consumption of more than 100,000 kWh and enables cost savings. Battery storage plays an important role in this, as it is able to smooth electricity demand and maximize the use of renewable energy.

Uninterruptible power supply

Uninterruptible power supply provides backup power in critical applications during power outages or fluctuations. Battery storage can serve as energy storage for UPS system batteries, extending their capacity and life. By charging battery storage during normal operating hours, they can provide more power in an emergency.


Stationary battery storage can facilitate the expansion of the charging infrastructure for electromobility by buffering high loads in the power grid and thus guaranteeing consistently high charging power. By storing excess energy, charging stations can become energy self-sufficient and ensure a more stable supply of electric cars. They thus reduce costs and complexity and protect the grid from overload.

Off Grid

Battery storage systems are an important component of off-grid applications because they ensure an independent power supply and store energy from various sources and make it available when needed. They smooth peak loads and provide a steady supply of electricity. Advances in technology today make battery storage more durable and reliable, making it a viable option for a variety of off-grid applications.

Grid Services

Battery storage systems can support grid services in various ways. For example, they can increase grid stability by balancing grid fluctuations with control power and stabilizing the grid frequency. They can also serve as backup systems to maintain a reliable power supply in the event of sudden power outages or to restart individual grid sections through the system’s inherent black start capability.
