The "Nagano Suwa Golf Mega Solar Power Plant," a mega- (large-scale) solar power plant with an output of about 46.8MW, is located on a former golf course on hills to the southeast of Lake Suwa (Suwa City, Nagano Prefecture, Japan) (Fig. 1).

Sonnedix Japan KK (Minato-ku, Tokyo) developed and runs this plant. It started operation in December 2017. This solar power plant became Sonnedix Japan's first project connected with an extra-high-voltage grid among those the company has developed in Japan.

Sonnedix Japan is the enterprise responsible for investment by the Sonnedix Power Holdings Ltd Group in Japan. A majority stake of the Sonnedix Group is held by institutional investors advised by JP Morgan Asset Management Ltd.

The group has developed, owns and runs solar power plants across the world, holding the rights to power generation facilities with a total output of 1.5GW in eight countries and regions, namely the US/Puerto Rico, Chile, South Africa, the UK, France, Italy, Spain and Japan. Of the 1.5GW, plants with a total output of more than 600MW are operating.

The group is currently engaged in 14 solar power generation projects in Japan. The output of the solar power plants that have started operation or are being constructed totals about 211MW.

In addition to Suwa City mega-solar plant, the other plants that have started operation are the ones in Hokuto City, Yamanashi Prefecture, with a solar panel capacity of 2.30MW (operation began in February 2015) and 2.20MW (operation began in May 2015), respectively (Fig. 2). The output of the three plants totals 51.3MW.

Sonnedix Power Holdings has been engaged in many of these development projects from the beginning, with its Japanese unit's lineup rapidly expanding as its projects increase.
