Who we are

Imagine the Possibilities.
Imagine the Future.

Finland-based Oy Windside Production Ltd. (Windside) is a specialized manufacturer of robust, rugged, and reliable vertical axis wind turbine (VAWT) systems. The unique "helix" shape was studied & refined for use as a wind turbine by Risto Joutsiniemi in 1978. It incorporates many unique & patented elements which result in an evolutionary leap from the classic Savonious turbine design.

Founded in 1982, Windside's dedication to impeccable-build quality, industrial strength solutions, and excellent customer service has gained the trust of uncompromising engineering & scientific professionals world-wide and made us a world leader in vertical-axis turbine systems. With a 30-year proven track record of success, Windside is here to stay.
