Project development of battery storage systems
Preparing electricity grids for the future with BESS.
We are flexibilizing the energy of the future
We firmly believe that the transition to 100% renewable power generation can only work if energy producers and consumers are intelligently connected so that electricity is always available when it is needed. Unlike many other storage technologies, battery technology is already both cost-effective and technically established – and is therefore already highly scalable. With the development of battery energy storage systems (BESS), we ensure that the energy grids are stabilized and relieved so that the expansion of renewable energies is accelerated. We want energy storage to be established as a sustainable and efficient component of the renewable energy landscape that enables flexibility and security of supply for the entire energy system. This is why we are involved in the Energy Storage Systems Association (BVES).
Our core market for the development of BESS is Germany. We are looking at both stand-alone and hybrid or site-integrated systems in combination with photovoltaic parks (co-location).
We develop these types of battery storage systems:
Co-Location Hybrid
Co-Location
Stand alone
Why does the energy transition need battery storage systems?
Stabilize networks
Battery storage systems work to support the grid and help to distribute more electricity from renewable energies. This can save billions in redispatch costs every year.
Making renewable energies usable around the clock
Battery storage systems create flexibility in the electricity market. In this way, renewable electricity can be stored cheaply during hours with a lot of sunshine and wind and then fed back into the grid when there is a lull or it is dark. In this way, we can accelerate the expansion of renewables.
Accelerate the phase-out of fossil power generation
Germany wants to phase out coal-fired power generation by 2030 and only operate gas-fired power plants as conventional power plants. To achieve this, we need new flexible generation capacity in the near future. Battery storage systems can provide this quickly and cost-effectively and should therefore provide a large proportion of the required capacity by 2035.
Our services
We advise you and support you as an experienced partner with extensive expertise.
For land owners
We develop your site: First, we check whether the site is suitable for the installation of a battery storage system. Among other things, we assess the availability of grid capacities, the building law framework and also take your noise and visual protection requirements into account.
As a lessor of land, you benefit from long-term rental income at an attractive level over 15 years and longer.
We take care of the entire implementation process, from technical planning, obtaining all the necessary permits, grid connection, electricity marketing and the construction and financing of the storage facility.
For municipalities and local authorities
With a large battery storage system, your municipality can make a decisive contribution to the success of the energy transition and your climate protection concept. You strengthen the local economy, increase the added value of unused land and generate additional income on the municipal side, e.g. through leasing/sales and business taxes.
You also strengthen your local electricity grid and can reduce the shutdown of wind power and photovoltaic systems.
For project developers
Are you looking for a competent and experienced development partner with a strong financial background to cover certain project development tasks within the framework of co-development? Or would you like to sell your project rights from a certain stage of development? Then get in touch with us!
Components of a battery storage system
Battery cells
Battery management system (BMS)
Inverter
During the charging process, these convert the alternating current from the supply grid into direct current. Conversely, they convert the direct current from the batteries back into alternating current so that it can be fed into the grid.
Cooling/air conditioning
The batteries like it neither very cold nor very warm. For this reason, special air conditioning technology is required – either air or water-based.
Communication & Power Management
Similar to solar systems, battery systems must also be able to be monitored and controlled remotely. This requires data loggers, routers and telecontrol technology.

BESS – From development to operation
We analyze an area with regard to its suitability as a location for a battery storage system. In doing so, we evaluate both the approval situation and the economic factors. We then enter the technical preliminary planning phase and present the project to the community.
- Site identification, site inspection and assessment
- Securing land through a lease or purchase agreement
- Grid connection request to the grid operator
- Initial design and preliminary technical planning
- Preliminary building application and project presentation in the community
Site analysis & pre-planning
The requirements for a successful planning application are developed together with the local municipality and the district.
- Planungsimpulse der öffentlichen Hand und Nachfragetreiber
- Obtaining building rights with the participation of the public and public interest groups
- Grid connection planning, route
Approval planning
The BESS is built and connected to the grid.
- Detailed and implementation planning, based on which the components are purchased
- Construction of the storage facility
- Grid connection and commissioning
Construction
Reliable operation of the storage tank after completion.
- Maintenance and repair (technical management)
- Asset management (commercial management)
- Electricity marketing
- Repowering / extensions
Operational management
