LG Electronics Builds Korea's Largest 340MWh ESS on Anjwa-do

[Asia Economy Reporter Suyeon Woo] LG Electronics has completed the construction of the largest energy storage system (ESS) in South Korea and is accelerating its efforts to capture the ESS market.

On the 7th, LG Electronics announced that it had completed the construction of the largest single-site ESS in South Korea at 'Anjwa Smart Farm & Solar City' located in Anjwa-myeon, Sinan-gun, Jeollanam-do, in collaboration with a special purpose company (SPC) formed by KCH Group, Korea Western Power, and Top Solar Group.

LG Electronics built a large-scale ESS with a power conversion system (PCS) capacity of 92MW and a battery capacity of 340MWh, considering economic efficiency and performance. Given that the average monthly electricity consumption of a four-person household in South Korea is 350kWh, assuming a daily usage of 11.7kWh per household, this battery capacity can store enough electricity to supply approximately 29,000 households for one day.

Based on its core ESS technologies such as PCS, power management system (PMS), and batteries, LG Electronics provides a total ESS solution covering not only products but also design and construction. The ESS supplied this time is equipped with LG Electronics' PCS and PMS, and LG Energy Solution's batteries. LG Electronics offers a three-year free warranty covering all ESS components, including the batteries.

LG Electronics designed the ESS by completely separating the PCS, batteries, and switchgear to maintain stable indoor temperature and performance. The switchgear is a device that stores the generated power into the batteries. Additionally, 24-hour monitoring and remote control enable rapid response in case of any abnormalities.

To maximize safety, LG Energy Solution's battery fire spread prevention system was also applied. In the unlikely event of a battery fire, smoke detectors detect the fire and directly inject water into the affected battery module to block the spread.

LG Electronics has successfully constructed major domestic projects including the frequency regulation ESS at Korea Electric Power Corporation's Singyeryong Substation, peak reduction ESS at POSCO Changwon Plant, peak reduction ESS at Hwanyeong Steel Dangjin Plant, and renewable energy-linked ESS at Gyeongju Wind Power.

An Hyuk-sung, Executive Director of LG Electronics' ESS Business Division, said, "We provide customers with the best service through ESS total solutions that combine industry-leading performance, convenience, and safety, along with reliable after-sales management."
