MHI Receives First Order for Japan's Largest 2.4 MW Wind Turbines.

Tokyo, Japan, Oct 18, 2006 - (JCN) - Mitsubishi Heavy Industries, Ltd. (MHI) has received a bulk order for 42 units of the Company's 2.4 MW wind turbine MWT92/2.4, a large-size wind turbine with a 2.4 MW (megawatt) 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 U.S. It marks the world's first order for the MWT92/2.4, which is the most powerful wind turbine manufactured by a Japanese company. The wind turbines on order will be used by PPM Energy for wind power generation.

The MWT92/2.4 is strategically targeted at global markets for large-scale wind turbine power generation. MHI proprietarily developed the machine and has verified its performance and reliability through testing since January this year using an actual 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 efficiently generating electricity even at modest wind velocity (about 8.5 m/sec). At the same time, the machine adopts MHI's proprietary "Smart Yaw" technology to fend off occasional gusty strong winds and withstand hurricane-force wind velocities up to 70m/sec.

MHI estimates that operation of 42 units of the MWT92/2.4 will generate 252,000 MWh/year, enough electricity to serve the needs of roughly 50,400 typical households in Japan. Wind power generation also enables reductions in fossil energy consumption and CO2 emissions. To supply the equivalent amount of power by burning fossil fuels would require some 58,800 kiloliters of crude oil per year, approximately equal to 300,000 oil drums. The resulting reduction in CO2 emissions is estimated at 176,400 tons.
