The tower features high strength steel for arctic climates. EWT’s cold weather package, black blades, ice detection and heating systems are specifically designed to optimize performance, reliability and operating efficiency in extreme low temperatures. The wind turbine will save over 165,000 gallons of diesel fuel per year.
