Green battery solutions for the energy transition
What we do
We develop turnkey large-scale battery projects professionally and in partnership, from the plot of land to energy marketing.
Are you looking for attractive and secure investments for your portfolio? Or do you own land near electricity grids? Please feel free to contact us.
Large-scale battery storage
Renewable electricity generation is volatile and runs counter to the electricity consumption of private households. Large-scale battery storage systems are needed for the flexible use of green electricity and a CO2-neutral energy world.
The storage units also serve to compensate for power fluctuations in the electricity grid and thus contribute to the security of the energy supply.
With our storage business models, we deliver attractive returns for investors.
Our core competencies
Market and product understanding
In-depth understanding of the market and products based on many years of experience. Professional partners for battery technology, software and construction.
Digitized property identification
Proprietary database with all substations in Germany and already over 1,500 prioritized properties based on 20 evaluation criteria.
Tailor-made lease agreements
Professional and bankable lease agreements that are concluded at the beginning of the process to secure the land and increase mutual trust.
Experienced network application
Expert capacity inquiries to the grid operator increase the chance of grid approval. To stabilize the grid, we are open to grid-neutral modes of operation and help the grid operators to define them.
Strong building rights expertise
Extensive experience in obtaining planning permission for battery storage facilities leads to rapid submission of planning applications and partnership-based cooperation with the municipalities.
Strong financial network
Large network of investors and banks to finance the large-scale battery projects enables a secure project.
