(EWP) is among the world’s largest manufacturers of small- and medium-sized grid-tied wind turbines. Founded in 2007 and headquartered outside of Vancouver, Canada, the company has a global installed base of more than 600 turbines. EWP manufactures turbines in the 50 to 225 kW range in Canada and the U.K. This privately held company is 40% owned by its employees, who share a long-term commitment to the products and the people who invest in them.
The first EWP turbines were 5 kW S-series machines, designed by David Laino and Dean Davis of Windward. The company started growing rapidly when it purchased a larger machine from Energie-PGE of Quebec, re-engineered it, and began building the 50 kW E-3120—first for the United States in 2009, and then for the U.K. in 2010. Cofounder and principal engineer David Laino says, “We don’t merely assemble turbines, we try to deliver products that are designed to work with the people associated with them, whether it’s the owner, installer, neighbor, or investor.”
Founded in 2001, Eocycle Technologies has been a pioneer in developing permanent-magnet electric generator and motor solutions based on the transverse flux topology. Eocycle’s generators and motors are well-suited for a variety of low-speed, high-torque applications in diverse markets, including wind turbines. For the past several years, Eocycle has focused on developing and fabricating a 25 kW direct-drive wind turbine for grid-tied wind energy applications.
The privately owned company’s first three-bladed production unit went into service in January 2012, and there was a two-bladed version prototyped for almost two years. The company has produced 12 units to date. Eric Lafleur, director of sales and marketing, says that the machine offers a “combination of dependable energy production, minimal maintenance, and very quiet operation under all weather conditions.”
British Evance was founded in 1999 by four engineers who had developed a 300 kW turbine, and took what they had learned to develop the Iskra AT-5 5 kW turbine, which was refined to become the Evance R9000. Evance is a privately owned limited corporation with key investors.
Evance has installations in the United Kingdom and Europe, the United States, and Australasia, with a network of resellers and installers around the world. The first 5 kW turbine model was launched in 2004, with the R9000 (latest model) launched in 2009.
More than 1,800 Evance turbines have been installed, and the machine is available in on- and off-grid configurations. Darrin Russell, Evance’s support coordinator for the Americas, reports that “every turbine installed is still in the field operating, and that the patented reactive-pitch blades with a steel shaft running the entire length of the blades has resulted in zero blade failures.”
