LG Chem has been chosen as the battery supplier for Japan’s largest commercial energy storage system (ESS) construction project.
LG Chem announced that it was recently selected as the battery supplier in the solar power plant-linked ESS project of Japan’s private renewable energy company, Green Power Development Corporation (GPD), in Hokkaido, Japan.
The company will supply the ESS system with a capacity of 31 megawatts, enough to power nearly 6,000 households in the region for a day. Also, the batteries to be used are equivalent to more than 2,000 units of electric vehicles by volt standards.
The ESS that LG Chem supplies will be used mostly to control and stabilize the output of the solar energy plants that produce power irregularly according to the environment, including weather. The produced electric power will be sent to the national power grid.
According to the contract, LG Chem will supply the batteries to four solar plants in Hokkaido of Japan in order by 2017.
Through this project, LG Chem became the first in the industry to meet the “1%/min rule,” the output variation regulation set forth by the Hokkaido power authorities, and is acknowledged as having the best ESS technology in the world.
LG Chem has developed the high output of ESS solutions through the long-term technical cooperation with the GPD, and succeeded in passing standards for the first time in Japan.
