Toda Corp announced Oct 8, 2019, that it will use electricity generated at its mega (large-scale) solar power plant located in Nagasaki City, Nagasaki Prefecture, Japan, for its Tsukuba Technology Research Institute in Tsukuba City, Ibaraki Prefecture.

Toda already joined the "RE100," an international initiative aimed at procuring electricity to be used for business activities with a renewable energy ratio of 100%. To achieve the goal, the company aims to achieve a renewable energy ratio of 50% by 2040 and 100% by 2050.

The mega solar plant, "Sakura-no-sato Mega Power Plant," has a total solar panel capacity of 2.141MW and a grid capacity of 1.99MW. It is expected to generate about 2.6GWh of electricity per year.

The solar panel and PV inverter employed for the plant are products of Mitsubishi Electric Corp and Toshiba Mitsubishi-Electric Industrial Systems Corp (TMEIC), respectively. Toda and TB Corporation (a company that is based in Isahaya City, Nagasaki Prefecture, and affiliated with the Kyushu Gas group) established a limited liability company (LLC), which started to sell electricity generated at the plant based on the feed-in tariff (FIT) scheme in 2015.

Minna-Denryoku Inc (Setagaya-ku, Tokyo) has been supplying 100% renewable energy-derived electricity to the Tsukuba Technology Research Institute since July 2019. Minna-Denryoku and the LLC concluded a specific supply contract to supply electricity generated at the Sakura-no-sato Mega Power Plant to Minna-Denryoku. And the electricity is used at the Tsukuba Technology Research Institute by using a block-chain power transaction system.
