Apply for Freen Wind Reseller Program

    Wind turbines (WPP) are designed specifically to provide sustainable power supply to individual households in continental areas with low wind energy potential.

    The main concept of building a wind turbine is to capture the energy of the air flow and deliver it to the consumer with the maximum achievable efficiency. Using innovative technologies in aerodynamics, electrical engineering and power converter technology, we are among the first turbine manufacturing companies to solve this challenge, while ensuring the reliability, durability, and commercial attractiveness of the proposed equipment.

    This approach, coupled with innovative management algorithms, makes it possible to achieve the lowest cost of electricity generation for wind turbines of small and medium capacity.

    Unparalleled and efficient vertical design for households and facilities

    with low maintenance costs and easy assembly

    Works at the lowest wind speed on the market - from 3 m/s

    and has the rated power of 15,6 kW at the speed of 12 m/s

    Eco-friendly production and disposal after 25 years of lifetime

    with quality warranties and support services from the manufacturer

    Noiseless on/off-grid operation without wind orientation mechanisms

    and fast energy payback times of the wind turbine

    Our Flagship Product: Freen-15 Wind Turbine

    Freen-15 is a wind generator with a capacity of 15 kW. It is designed for on-grid and off-grid energy generation for homes and farms.

    The vertical ultra-light turbine is effectively operated in multiple regions under variable wind conditions.

    Patented wing design does not require reconfiguring the turbine to the wind’s direction change. Thanks to the low noise level, they can be used on various residential and public buildings.

    EAS and EU European Regional Development Fund support

    Freen OÜ has received support for the project "Freen OÜ investments to increase production capacity and create new jobs" from the grant measure "Ida-Viru entrepreneurship investments" of the Just Transition Fund. The implementing unit of the grant measure is EAS. During the project, the company plans to build an extension to the existing factory and acquire several additional manufacturing equipment. The goal of the project is to create the ability for the applicant to enter a new business direction and start producing both their own serial wind turbine models and to offer production capacity to other Estonian wind turbine manufacturers as well. As part of the project, the necessary equipment will be acquired and an extension to the existing production building will be carried out. As a result of the activity, several jobs with higher added value will be created in the region. The Just Transition Fund co-finances the project "Ida-Viru business investment support measure" with a total of 2,600,000 euros.
    Freen OÜ on saanud Õiglase Ülemineku Fondi „Ida-Viru ettevõtluse investeeringute“ toetusmeetmest toetust projektile „Freen OÜ investeeringud tootmisvõimekuse tõstmiseks ja uute töökohtade loomiseks“ Toetusmeetme rakendusüksuseks on EAS. Projekti käigus on ettevõttel kavas ehitada olemasolevale tehasele juurdeehitus ning soetada juurde mitmeid täiendavaid tootmisseadmeid. Projekti eesmärgiks on luua taotlejale võimekus siseneda uude ärisuunda ja hakata tootma nii enda seeriatuuliku mudeleid kui pakkuda tootmise võimekust allhanke korras ka teistele Eesti tuulikutootjatele. Projekti raames soetatakse selleks vajalikud seadmed ja teostatakse olemasolevale tootmishoonele juurdeehitus. Tegevuse tulemusena luuakse piirkonda juurde mitmeid kõrgema lisandväärtusega töökohtasid. Õiglase Ülemineku Fond kaasrahastab projekti „Ida-Viru ettevõtluse investeeringute toetusmeetmest“ kokku 2 600 000 euroga.
