TOKYO—Toshiba Corporation (Tokyo: 6502)
today announced that it has delivered
battery energy storage systems
integrating the company's SCiB™,
an innovative lithium-ion secondary battery
to Kyushu Electric Power Co., Inc.,
for a demonstration project to
expand introduction of renewable energy sources
on remote islands.
The systems have been installed
in substations on
Tanegashima Island and Amamioshima Island,
in Kagoshima prefecture,
and will be used to demonstrate
the integration and optimum control of
battery energy storage systems
deployed to manage frequency regulation and
maintain stable power supply on remote islands,
which are increasingly turning to
renewable energy sources.
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 tends to fluctuate
due to intermittent power outputs
from the renewables.
Toshiba's battery energy storage systems
provide such islands with an excellent solution
for 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 known for their long-life and
excellent performance:
support for over 10,000 charge-discharge cycles;
rapid charging and discharging;
high level reliability and operational safety.
Toshiba is promoting
battery energy storage system globally
as a support for stable power supply,
and is involved in
Smart Community projects around the world.
In Japan, these include
a renewable power supply project in Okinawa and
a large-scale urban project
serving homes and offices in Yokohama.
Overseas, they 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, reliable 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., Inc.
for a battery energy storage system
with the output of 40MW, the world's highest class.
There is a growing global demand
for continuous, high quality power supply.
Toshiba delivers solutions that
facilitate stable utilization of
high quality renewable energy,
and expects to expand
its large-scale battery energy storage systems business
in the global market.
