Our history
of success
It took us almost 10 years to reach this current point. Our tremendous journey has been full of trial and error, continuous R&D, rigorous testing of new hypotheses, application of innovative materials, and non-stop invention — all to finally succeed in creating Darrieus wind turbines with industry-leading energy conversion efficiency, a low cost of ownership, and outstanding applicability to all kinds of usage scenarios.
The first commercial vertical wind turbines, based on Georges Darrieus’ invention, were deployed in the United States back in the 1980s. 30 years later, Valerii Nebesnyi, the founder of ANEM and a serial inventor, revolutionized the original concept paving the way, to the emergence of a patented technology for building turbines that are considerably lighter than both traditional propeller-type turbines and the rigid vertical-axis Darrieus turbines.

Today, our family of small wind turbines — based on our proprietary designs and patented technical solutions — offers consumers and energy operators worldwide a great opportunity to start reaping the benefits of renewable energy without making million-dollar investments.
Our facility
Our production facility is strategically located on the shore of the Gulf of Finland, in close proximity to major European highways, ports, and railway hubs, which dramatically facilitates logistics and enables us to ship our products worldwide without delays.
This modern factory has a combined area of over 25,000 square meters and is designed for the mass production of small wind turbines (4,000 units yearly with potential for a higher output).
In addition, our wide range of modern CNC equipment in combination with our technical expertise enable us to manufacture high-quality, complex metal assemblies and turbine components
End-to-end quality control is achieved through a well established multi-tier QA process and a corporate ERP system that logs the results of each production stage. Precision-sensitive components are additionally checked using the ZEISS Contura machine.
Our production processes are
certified.
Our mission
Our company’s mission is to make small wind energy affordable and accessible to consumers in every corner of the world, including the most remote locations without a regular or reliable power supply. To that end, our R&D team works tirelessly to improve our current turbine designs and come up with new features, materials, and components to stay ahead of the curve and follow the chosen path of continuous improvement.
We are committed to excellence in every aspect of our business, from the design and production of cutting-edge wind turbines to exceptional customer service and strong partnerships worldwide. With our unwavering dedication to sustainability, we strive to empower individuals and businesses to harness the power of wind energy, reducing their carbon footprint and contributing to a greener future. Through continuous research, development, and collaboration, we are making wind energy accessible and efficient for consumers and partners across the globe.

Project funding
Freen OÜ is backed by a considerable pool of private investors who have already committed EUR 36.4 million to our wind energy project. In addition, we actively apply to relevant green energy programs and have succeeded in securing additional funding from various European renewable energy initiatives.
For example, we have received substantial financial support under the Ida-Viru Entrepreneurship Investments grant of EUR 2.6 million from the EAS-administered Just Transition Fund, to bolster our production capacity and generate new employment opportunities.
The company’s initiative comprised construction of an extension to our existing factory and procurement of additional manufacturing equipment. The overarching objective was to diversify the Freen’s business pursuits by enabling the company to manufacture our patented wind turbines and offer our metal processing capabilities to other European wind turbine manufacturers.
This initiative entailed acquisition of essential metal processing machinery and expansion of the existing production facility. A number of high-value jobs were created in the area as a result of this undertaking.
Our achievements
As a proud member of the WindEurope association and recipient of numerous grants from the European Union’s green initiatives, we are committed to expanding our market exposure through partnerships, media, and participation in relevant industrial events, such as the WindEurope Annual Event 2024 in Bilbao, Spain.
