MHI developed wind turbine for cold winter regions in US

Mitsubishi Heavy Industries Ltd. (MHI) has developed a wind power generation system able to generate electricity in cold winter areas at 30°C below freezing. This is in response to increasing installation of wind turbines in cold regions of the United States, with each unit having an output of 2,400 kilowatts. The system has been scheduled for installation for testing in May and production will begin after performance is confirmed. The wind turbine uses a lubricant that remains liquid at low temperatures. The unit also has a built-in heater to protect the electrical system and make operation in cold winter regions possible. When not operating in standby mode, the wind turbine can withstand temperatures as low as 40° below freezing. (March 23, 2009)
