Japan's Largest Wind Turbine to Be Built in Yokohama

Mitsubishi Heavy Industries, Ltd. (MHI) announced on August 2, 2004 that it will build Japan's largest wind turbine at the Kanazawa plant of its Yokohama Dockyard & Machinery Works for trial runs by the end of March 2005. The turbine is called the MWT92/2.4; MWT stands for Mitsubishi Wind Turbine, the 92 indicates the 92 meter rotor, and the 2.4 indicates its output, 2.4 megawatts. It is estimated that the turbine will be able to provide the electrical needs of about 1,200 households, which will reduce carbon dioxide emissions by some 3,500 tons per year. The electricity generated will be sold to Tokyo Electric Power Co.

The MWT92/2.4 will be the largest wind turbine in Japan in terms of both output and size. As its rotor has a diameter of 92 meters, the highest point of the rotor blades will be 116 meters off the ground. The latest technology has been adopted for high performance in a low wind-speed area. This new turbine can generate electricity at a wind speed of 3.0 meters per second and also withstand strong typhoon winds. As it can catch more wind, it can generate more electricity than equivalent models already installed in the U.S. and Europe.

In Japan, average wind speeds are low except during the typhoon season, which brings violently gusting winds. Wind turbines that are particularly suited to the Japanese climate have therefore been in great demand. While 1mW turbines have already been commercialized and sold both in the domestic and overseas markets, there is a growing need for more powerful wind turbines. MHI has thus decided to build the MWT92/2.4 at its new verification experiment facility as a way to meet these needs.
