Toshiba Corporation recently announced that it has delivered battery energy storage systems integrating the company’s lithium-ion secondary battery to Kyushu Electric Power Co. for a demonstration project of renewable energy resources on remote islands. The systems have been installed in substations on Tanegashima Island and Amamioshima Island, in Kagoshima prefecture. The systems will be used to demonstrate the integration and optimum control of battery energy storage to manage frequency regulation and maintain stable power supply on remote islands. The demonstration program will run for three years to fiscal 2016.
When large-scale renewable energy sources such as wind and photovoltaic are integrated into power grids on remote islands, power frequencies tend to fluctuate due to intermittent power output from renewables. Toshiba’s battery energy storage systems are designed to provide islands with efficient and effective frequency regulation.
The maximum output and capacity of the systems Toshiba has delivered are 3,000kW and 1,161kWh for Tanegashima Island and 2,000kW and 774kWh for Amamioshima Island. Both systems integrate Toshiba’s SCiB lithium-ion secondary batteries, which are designed to support over 10,000 rapid charge-discharge cycles while offering high levels of reliability and operational safety.
Toshiba is involved in smart community projects around the world, including a renewable power supply project in Okinawa and a large-scale urban project serving homes and offices in Yokohama. Overseas, other smart community projects include a collaborative on-site verification testing program with GAS NATURAL FENOSA, one of Spain’s leading natural gas utilities, that uses a transportable battery energy storage system to achieve an efficient and stable distribution network. In commercial systems, Toshiba has received an order for the battery energy storage system from Rome-based ACEA Distribuzione S.p.A (Gruppo ACEA), one Italy’s leading public utilities, and in Japan an order from Tohoku Electric Power Co. for a battery energy storage system with the output of 40MW.
