Softbank Corp. and Kintetsu Corp. both have plans to build and operate large-scale solar power plants, industry sources said Thursday.
Softbank subsidiary SB Energy Corp. intends to team up with trading house Mitsui & Co. to construct a plant on a 50-hectare site in Yonago, Tottori Prefecture, by summer 2013.
The planned capacity of the photovoltaic-powered facility is 30,000 kw, which is enough to cover about 7,500 households.
SB Energy, which plans to build and operate solar power plants at more than 10 locations in Japan, has already decided to construct huge plants in Kyoto, Gunma and Tokushima prefectures.
Kintetsu intends to build a 20,000-kw plant serving about 6,000 households on a site along its railway in Mie Prefecture before March 2014, becoming the first railway other than Japan Railway firms to launch a mega-solar plant project.
