South Korea’s LG Chem Inc. has secured a deal to supply lithium-ion energy storage systems (ESS) to Japan.
The nation’s largest battery manufacturer will supply ESSs for four solar plants in a contract worth more 300 billion won (US$272.7 million).
Each ESS will have a daily capacity of 31 megawatts – enough to power about 6,000 households a day. They will store electricity when weather conditions allow and dispensing it during overcast days, the firm said.
The deal was struck with Green Power Development Corporation (GPD) of Japan to supply the secondary batteries for ESS business in association with the solar PV project in Hokkaido by 2017.
Japan has been building the world’s largest storage battery system in Hokkaido for stable power supply as it pursues a mix of renewable energy in the wake of the 2011 Fukushima nuclear crisis.
LG Chem CEO Kwon Young-su said: “LG Chem was able to pass the world’s highest technology regulation in Japan based on know-how in the electric car battery and the energy storage system.
“We hope to clinch other battery deals in North America and Europe.”
LG Chem secured the deal after it passed the regulatory testing on the rigorous power variation control in Japan.
