Iitate Madeina solar power plant
It all started when a company asked if we could do something for Iitate Village, which was forced to evacuate its entire village due to the nuclear accident. As part of the reconstruction effort, we co-funded a 10MW solar power plant with Iitate Village, which started operation in 2016, and by 2020, two 3.2MW wind turbines will be installed, creating Japan's first renewable energy cross power plant.

Hokkaido
2012
Kaminokuni Wind Farm, Electrical facilities
This is a large-scale wind power plant with 12 units of 2.4MW each, and a 10km transmission line is being laid to connect the plant to Hokkaido Electric Power. We designed and constructed this transmission line. A helicopter was used to transport materials and equipment through the mountainous area.

Ishinomaki Tomarihama solar power plant
This is the largest solar power plant in Tohoku (9.5MW), built on farmland that has not been used for many years on the Oshika Peninsula. SPC Sun Energy Ishinomaki was established and is operating the plant for the purpose of reconstruction from the earthquake and the spread of renewable energy. We are also participating in this SPC, and are involved in the solar power generation business as well as construction work, operation and maintenance.
