The Biessenhofen Solar Park is being built on the northern edge of the municipality of Biessenhofen, on a site located between the B16, the Buchloe–Lindau railway line, and Bachtelsee. Due to its immediate proximity to the Buchloe–Lindau railway line, the project site is a prime location. This project involves a solar park with a generation capacity of approximately 4 MWp and a planned battery storage system with a capacity of 2.8 MWh. It will supply power to around 1,380 households for approximately two hours, even when the sun is not shining.

Efficient Planning Thanks to Proximity to the Railroad Line – Biessenhofen Solar Park
Due to its immediate proximity to the Buchloe–Lindau railroad line, the project site is a prime location. The permitting process is streamlined in this case, as the impact on the living environment and natural habitat is considered minimal due to the site’s proximity to the railroad line.

Project Progress: Biessenhofen Solar Park
Planning Phase
A solar park project begins with a comprehensive conceptualization and analysis phase. Teams of experts evaluate potential sites for suitability, taking into account factors such as solar irradiance, access to the power grid, environmental requirements, and technical feasibility. At the same time, initial plant designs, economic feasibility calculations, and feasibility studies are developed. Additionally, consultations with landowners take place, and the optimal route for the power lines to the grid connection point is determined. The goal of this phase is to develop a robust, sustainable, and economically viable overall concept.
Approval Phase
Once the project concept has been finalized, the formal approval process begins. Project managers submit all necessary documentation—including, for example, applications for building and environmental permits, as well as for grid connection. Environmental or species protection assessments are often prepared as part of this process. Depending on site conditions and the scale of the project, this phase can vary significantly and take anywhere from several months to several years.
Construction
Once all permits have been obtained, construction begins. The site is first prepared before the mounting structures, solar modules, and inverters are installed. At the same time, the internal and external cabling is installed and the connection to the public grid is established. The construction period depends on the size of the system but typically ranges from a few weeks to several months. Finally, a detailed technical inspection is conducted to ensure safe and reliable operation.
Operation
Once all functional and safety tests have been completed, the solar park begins regular operation. From this point on, the plant continuously feeds climate-friendly electricity into the grid. With the final technical acceptance, long-term operation begins, which is typically designed to last for many decades. This generates renewable energy on a permanent basis, contributing to a sustainable electricity supply.
Frequently Asked Questions
Solar Energy Reduces Dependence
The transition to domestic and renewable energy is necessary to ensure independence from global commodity markets. Germany meets most of its energy needs in the building, transportation, and industrial sectors by importing energy resources from abroad. By using locally generated and regionally consumed solar energy, we are gradually reducing this dependence and, in combination with the integration of energy storage, ensuring a reliable and independent energy supply.
An expert assessment of glare was conducted, and plans were adjusted accordingly
Prior to the development of the occupancy plan, a comprehensive glare assessment was conducted. In particular, it was agreed to plant hedges that would significantly reduce the visibility of the solar park and minimize glare. The solar park is enclosed at the property line by a fence, which, together with the substructures of the solar modules, minimizes soil sealing and allows small wildlife to pass through.
Simplified approval process under the provisions of the Federal Building Code (BauGB)
Due to its proximity to a railway line, the site is classified as a “privileged area” under the provisions of the German Federal Building Code (BauGB), for which a simplified approval process applies for obtaining a building permit. Public participation therefore took place in a representative manner through the involvement of municipal and county authorities. In this process, all public interest groups were involved in accordance with the procedure and were given the opportunity to provide feedback.
Landscaping and Maintenance of the Project Areas in Harmony with Nature
The municipality has established comprehensive guidelines for the seeding and landscaping of the area following the completion of construction work. To this end, hedges will be planted on the western and southern sides of the project areas, while a border of tall perennials is planned for the northern and eastern sides. The maintenance plan calls for two mowing cycles per year and completely avoids the use of fertilizers and pesticides.
Dismantling or Repowering – Clearly Defined Options After 30 Years
The operational lifespan is limited (typically 30 years). After that, there are two options: The PV system can either be dismantled or renewed and kept in operation. Even after a long operational lifespan, the components still maintain high performance levels, making continued operation or renewal possible in principle. There are no costs to the owners or municipalities; these are borne by the solar park operator.
Minimal Disruption During Construction and Operation
During the construction phase, there will be the usual disruptions associated with a building project. All requirements regarding construction windows and the minimization of any impacts will be met. Once operational, the solar park will not generate excessive noise or other emissions that are louder than the noise levels of a road or a railroad track.

Solar Farms – Energy of the Future
Solar farms are at the heart of the energy transition. From planning to installation, we create a sustainable solution that converts sunlight into clean electricity. Our systems supply energy to thousands of households and save tons of CO₂ every year.
How does it work? Photovoltaic modules convert light into electricity, and inverters make it usable—all monitored by smart systems. This is how green energy is generated, day after day.
