Marubeni Corporation’s fully owned subsidiary, Mibugawa Power Company, held the opening ceremony today for a small hydro power plant named Tateshina No.2 Power Station that has completed construction in December 2013 and commenced commercial operation from 15 January 2014 in Chino City, Nagano Prefecture.

The plant is installed in the facility of Takinoyu Dam Land Improvement District Agricultural Waterway that locates next to Sibukawa Ohashi in Itokaya Ku, Chino City, Nagano Prefecture. Maintenance activity for the plant expects to be streamlined as Tateshina No.1 Power Station that commenced commercial operation from June 2011 is located in the same waterway.
