The "EBH Chino Stadium Power Plant," a mega- (large-scale) solar power plant with a solar panel capacity of about 1.33MW and a PV inverter rated capacity of 1.26MW, is located in Chino City, Nagano Prefecture, Japan (Fig. 1).

As the plant's name represents, solar power generation facilities were set up on a former baseball stadium. Along with the stands for hundreds of spectators, the dugout built below ground level and the official room behind the backstop show the stadium was big enough for major local games (Fig. 2).

This baseball stadium was not a public facility, but a welfare facility of a leading precision equipment manufacturer based in the neighboring area. Next to the stadium is the company's dormitory for single employees, which is still being used.

The mega-solar plant was developed by renting the former stadium site. The initial power producer was a special purpose company (SPC) established by Next Energy & Resources Co Ltd (Komagane City, Nagano Prefecture) and started selling power in July 2016. One year later, ownership of the plant was transferred from Next Energy's SPC to EnBio Holdings Inc (hereinafter EnBio HD). The plant was sold and acquired through the so-called "secondary market."

Around the same time, another solar power plant of Next Energy's SPC was also taken over by EnBio HD one year after the operation start in Ina City, Nagano Prefecture. This is the "EBH Ina Power Plant" with a solar panel capacity of about 436.8kW and a PV inverter capacity of 490kW (Fig. 3).
