18 October 2006 — Mitsubishi Heavy Industries, Ltd. (MHI) has received a bulk order for 42 units of the MWT92/2.4, its large-size wind turbine with a 2.4 MW rated output, from PPM Energy, Inc., an American electricity provider.
The order was received through Mitsubishi Power Systems Americas, Inc. (MPSA), MHI’s power systems operation base in the United States. It marks the world’s first order for the MWT92/2.4. The wind turbines on order will be used by PPM Energy for wind power generation.
The MWT92/2.4 is targeted at global markets for large-scale wind turbine power generation. MHI developed the machine and verified its performance and reliability through testing since January this year using a production model built at the Kanazawa plant of MHI’s Yokohama Dockyard & Machinery Works.
The MWT92/2.4 is Japan’s largest wind turbine in terms of both rotor diameter and rated output. With a tower height of 70 meters and a rotor diameter of 92 meters, the highest point reached by the blade tips is 116 meters above ground. Adopting 44.7-meter-long blades, the longest in its class, the MWT92/2.4 is capable of generating electricity even at modest wind velocity (about 8.5 m/sec). MHI engineered the “Smart Yaw” technology to protect against occasional gusty strong winds and withstand hurricane-force wind velocities up to 70m/sec.
PPM Energy, headquartered in Portland, Oregon, is a member of the ScottishPower group of companies. It operates in the U.S. Midwest and Canada in the areas of natural gas-fired power generation, electricity wholesaling and natural gas storage, in addition to wind power generation.
