About Fleximaus GmbH

Fleximaus GmbH has set itself the task of advancing wind power in Europe. For this reason, we work every day to ensure that humans and animals can live side by side in a healthy environment. To this end, we develop smart solutions that support operators, technical managers or project developers of wind farms in complying as efficiently as possible with requirements that are relevant to approval.

Avoid blanket shutdowns, reduce unnecessary downtime, maximise returns with minimal effort: Fleximaus builds a bridge between species protection and the economic generation of wind energy. The direct proximity to our customers is a decisive advantage for location-specific implementation.

Our path: full wind power ahead

The history of Fleximaus GmbH is closely linked to the development of the software of the same name. After all, the flexible bat shutdown was the only product in our portfolio at the beginning. The first milestone, so to speak, on the road to a profitable future for all.



Every success story begins with the desire to make something better. So is ours: from 2012 to 2014, Jochen Rößler already noticed that the permit requirement “bat protection in wind farms” resulted in high yield losses for Bavarian citizen wind turbines. In order to relieve the burden on the citizen wind farms he manages, the technical operations manager developed an intelligent optimisation system.

He had one goal in mind: everyone should benefit from Fleximaus. Both native bats and different wind farm operators – from small farmers in Bavaria to globally operating energy supply companies. This idea gave rise to today’s protected product name.

In August, the first software vision saw the light of day. The prototype was already installed in wind farms in September and tested under real conditions.



We conducted further research on bat conservation and evaluated the data collected in the field trial. Result: Fleximaus reduced the previously high shutdown times and yield losses by over 50 percent. This was a sign for us to equip more citizen wind farms with the successful technology.



This year, the expansion of the hardware as well as its adaptation to long market availabilities was the focus of our activities.



A flexible as well as quickly implementable mowing shutdown enabled us to protect additional animal species such as birds of prey. In addition, our experts further developed the hardware and software of Fleximaus to make it fit for the implementation of both previous and additional requirements.



Fleximaus finally received a Europe-wide patent after four long years. We looked after the first 100 plants – new customer requirements as well as even more intensive analyses led to a further expansion of functions.



Fleximaus grew in terms of personnel: the first full-time IT specialist came on board and developed Fleximaus 2.0 together with external experts and our managing director. To this day, this system forms the basis for meeting site-specific requirements; a real relief for operators and managers of wind energy plants.



Both the new customer portal and Fleximaus 2.0 went online and reduced revenue losses caused by unnecessary shutdowns across Germany. Through further optimisation of data transmission, the requirements of IT and data security, as well as access protection and / or documentation, could be ensured.


The number of managed turbines continues to grow steadily. New functions, such as area-based mowing shutdown and easy-to-activate protection specifications, as well as shadow switching, make it easier for our customers to fulfill all approval-relevant requirements. Increasingly, new wind farms are also being equipped with Fleximaus from the time of commissioning, where our system takes over all functions: Bat protection, bird protection and shadow switching.


It is now about your money and our common future. Every kWh from renewable energy is important. Fleximaus combines species protection and wind energy and offers economic solutions to implement the requirements in your wind farm. With 350 wind turbines in care and the first wind farm in France with optimized bat protection, Fleximaus offers services throughout Europe for more green energy while maintaining a high level of species protection.

And tomorrow?

We are constantly growing and developing: on the one hand, our professional team offers a far better service, as well as even faster response times, and on the other hand, our software, which was previously financed from our own funds, is proving its reliability in numerous wind farms throughout Germany – as well as its economic added value for their operators.

The location-specific adaptable system can be designed to meet new species protection requirements, both to meet the individual needs of wind farm operators and to continuously increase the productivity of the respective wind energy plant – each customer benefits from ongoing system optimisations through existing service contracts. Fleximaus can be used with all plant types and has already been approved by well-known manufacturers.

In order to permanently fulfil the wishes of our customers, the team of Fleximaus GmbH will continue to work on the independent optimisation of the software in the future. Extensive experience enables us to adapt the system more and more individually to different circumstances.
