LG Electronics Supplies Commercial Energy Storage System in Hawaii, USA

[Asia Economy Reporter Suyeon Woo] LG Electronics will supply commercial Energy Storage Systems (ESS) to Hawaii, USA. This is the first time LG Electronics has supplied commercial ESS to a U.S. state government, and the company plans to expand its business in the overseas ESS market based on this contract.

LG Electronics announced on the 24th that a Korea-U.S. consortium, including LG Electronics, recently signed a supply contract related to the 'Microgrid' construction project promoted by the Hawaii state government. A microgrid is an eco-friendly power system that uses renewable energy sources such as solar and wind power.

The Korea-U.S. consortium includes, besides LG Electronics, the Korea Energy Technology Evaluation and Planning (KETEP), AI solution company for energy technology Incord Technologies, University of Hawaii, Seoul National University, and Gwangju Institute of Science and Technology.

LG Electronics plans to supply the energy storage system to the Natural Energy Laboratory of Hawaii Authority (NELHA), a research institute under the Hawaii state government, starting from June this year. LG Electronics’ energy storage system will be used to supply power to the seawater supply system for aquaculture farms operated by the institute. The Hawaii state government aims to expand eco-friendly energy policies and supply 100% of its power from renewable energy sources by 2045.

LG Electronics’ ESS is packaged with a 250kW-class Power Conversion System (PCS) and Power Management System (PMS), a 756kWh-class battery, heating and cooling equipment, fire extinguishing facilities, and switchgear that stores generated power in the battery and delivers it to the power grid, making installation simple. This battery capacity is enough to fully charge about 10 electric vehicles with a driving range of approximately 400km simultaneously.

LG Electronics has concentrated differentiated technology in the PCS. The PCS is durable enough to withstand temperatures from minus 30 degrees Celsius to plus 50 degrees Celsius and can connect multiple PCS units in parallel, enhancing installation versatility. Additionally, LG Electronics’ PCS introduces the 'Uninterruptible Emergency Power Supply' function for the first time, which quickly and continuously supplies power within 20 milliseconds (20/1000 seconds) even when a power outage occurs.

Moreover, the ESS to be installed this time allows for 24-hour monitoring, enabling rapid response in case of abnormalities. Customers can remotely control not only the PCS and battery but also the air conditioning system.

Hyukseong Ahn, Executive Director of LG Electronics’ ESS Business Division, said, "We will lead the overseas ESS market by leveraging differentiated products based on industry-leading technology."
