The move to spread renewable energy generation has been gaining momentum thanks to the special measure that obliges electric power companies to purchase surplus electricity generated by renewable energy. Ricoh Leasing decided to lease small-size wind generators to plants, hospitals, and commercial facilities.
The small-size wind generator to be leased is built by Loopwing, a venture company specializing in wind generators. Loopwing’s TRONC is characterized by a structure strong against blast. It does not create wind noise, nor does it need so much space for installation. Because it catches wind in a three-dimensional manner, the windmill rotates with a wind velocity as low as 2 m/h and has more than 40% power exchange rate at a wind velocity of 8 m/h. Ricoh offers four types of TRONC ranging from 500 W to 11 kW, and plans to lease a 500 W type for monthly fee of 50,000 yen for a period of 6 years together with an electric bulletin board to show the annual power output and reduced CO2 emissions. The 5 kW type can generate 2,683 kW per year at a wind velocity of 4 m/h, supplying enough electricity for the annual consumption of a standard household.
