Kita-Toyotomi Substation

Upper Hokkaido in northern Japan has favorable wind conditions and abundant open land, making the area suitable for wind turbines. Renewable-energy power suppliers have been applying to construct wind farms in the area, but as these wind farms proliferate, fluctuations in their power output will increasingly impact the electricity demand-and-supply balance. Consequently, energy storage systems must be introduced to improve the balance and thereby strengthen the grid with stable power supply.

In view of this situation, it is going to be developed what the company believes will become the world's largest energy-storage system (240MW output and 720 MWh rated capacity) at Kita-Toyotomi Substation in Toyotomi, Teshio (Hokkaido) which is owned by North Hokkaido Wind Energy Transmission Corporation; the energy-storage system is expected to commence operation by March 2023.
