Battery Storage: Key to a successful energy tansition

Battery storage solutions: 

for energy independence and stable grids.



Battery storage systems are crucial for the success of the energy transition, as they stabilize the power grid and ensure continuous electricity supply. They also positively impact electricity pricing.

VSB recognized the importance and potential of battery storage technology early on. With the pilot project "Battery Storage Wölkisch," the team has been able to build valuable technical expertise.

Why VSB?

We prioritize close collaboration with communities and all citizens. Absolute transparency, openness, and a dialogue on equal footing are of utmost importance to us. Through this approach, our extensive expertise, and our high-quality standards, we ensure the success of every partnership.

How communities and landowners benefit from battery storage projects:



Benefits for communities

Regulatory power and grid quality

Battery storage systems respond quickly to fluctuations in energy supply, thus supporting grid quality. They significantly contribute to the stability and reliability of the power grid.

Increased flexibility and cost efficiency

Energy producers can respond more flexibly to changes in energy demand, making renewable energy more efficiently usable. Additionally, battery storage systems can store energy at low prices and release it at peak prices.

Local energy autonomy and infrastructure

By storing locally generated energy, communities can operate more independently from the regional electricity market. Investments in battery storage systems strengthen local infrastructure and promote regional economic development.


Benefits for landowners

Attractive lease revenues and financial security

Leasing land for storage projects creates long-term income sources and provides financial planning security. Landowners bear no risk as all costs are covered by the VSB Group, from project development to insurance.

Preservation of land use and environmental protection

The land remains under the ownership of the landowners, who can often continue to use it for other purposes. After the operational life of the battery storage system, the site will be decommissioned in accordance with the highest quality standards.

CO2 reduction and clean energy supply

The expansion of battery storage systems significantly contributes to reducing harmful emissions and supports clean energy supply. This is an important step towards an environmentally friendly energy infrastructure.

With our battery storage projects, we not only provide solutions for sustainable energy supply but also create value for communities and landowners.


How does a battery storage system work?

The functioning of a battery storage system -  Using the Wölkisch example


  1. Wind energy conversion
    The kinetic energy of the wind is converted into rotational motion by the rotor of the wind turbine. The generator then converts this motion into electrical energy.
  2. Voltage transformation for the high voltage grid
    The energy from the wind farm reaches the VSB-owned substation with a medium voltage of 20 kV. There, the voltage is transformed to 110 kV using a transformer.
  3. Battery storage integration into the distribution network
    A portion of the energy generated by the wind farm flows into the storage system to provide regulatory power for the grid. Due to the intermittent nature of wind and solar energy, frequency fluctuations in the power grid increase. To maintain grid stability, the grid operator requires short-term available capacities, known as regulatory power. This capacity is auctioned weekly by transmission system operators. During grid fluctuations, electricity is either stored in or drawn from the battery. The storage operator receives financial compensation for providing the reserve capacity of the battery as primary control reserve (PCR).
  4. Distribution network integration
    The substation ensures that wind energy can be fed into the local distribution network. The grid operator ensures that the electricity reaches households in the region.
  5. Electricity delivery to households
    For wind power to reach household outlets, it must be transformed from high voltage back to the standard household voltage of 230 V. Transformers ensure this process. The Wölkisch wind farm produces enough green electricity to supply around 11,500 three-person households.
