LS Electric will deploy a 20MW/90MWh battery storage system in Japan after it was awarded the contract through a competitive solicitation.

Sungrow has agreed to supply ‘approximately’ 500MWh of battery storage technology to Sun Village, a Japanese solar PV project developer.

Home battery storage aggregation projects have launched with participation of Tokyo Electric Power Co, and Tokyo Gas, two major utility companies in the Japanese capital.

As Japan’s heavily regulated energy markets continue a process of liberalisation and supposedly increasing consumer choices, utility TEPCO has launched a smart electricity tariff enabled by the capabilities of residential battery storage.
