We help people produce electricity that is both environmentally sound and economical. We are North America’s leading supplier of midsize wind turbines and have supplied projects with the largest and widest capacity range of midsize wind turbines available anywhere. We also design and manufacture many new wind turbine components including control systems. We stock wind many turbines from 90 kW to 600 kW at our 5 acre facility in San Leandro, California. As the wind industry continues to manufacture larger units and have discontinued production of previous models, remanufactured wind turbines offer the market sizes no longer provided by the world’s major manufacturers. Rebuilt wind turbines are generally suitable for projects requiring under a few megawatts worth of generation. We specialize in remanufacturing wind turbines originally produced by Vestas, currently the world’s leading wind turbine manufacturer. Our turbines feature options never before installed in North America, such as tubular towers for Vestas turbines under 150 kW. Our wide range of choices gives us the flexibility to accommodate varied requirements. With a satisfied coast-to-coast client list from California to Delaware and even remote locations in Alaska, we have developed the expertise required to supply varied locations. Having converted, remanufactured, and supplied the industry’s first commercial wind turbine from 50Hz to 60Hz many years ago, we also have the necessary in-house engineering expertise to supply international projects with grid voltage and frequency environments other than those used in North America. Thank you for visiting this site. We look forward to serving your renewable energy needs.
