About Us

Windstream Power was established in 1974 in North Hatley Quebec, Canada.  Over the years, Windstream Power (formally Thermax) has manufactured small wind turbines, microhydro systems and the popular human power generator series using our reliable permanent magnet DC generators.

A move down to Vermont in the 1980’s established a strong foothold in the industry. In 2005, Windstream joined up with and became part of the Bowles Corporation group in North Ferrisburgh. Vt.

Windstream Power is a registered trademark.

Our products are manufactured by a dedicated staff of 14 in rural Vermont. We are extremely lucky to work with a wonderful group of people in a beautiful part of the world.
