LG Energy Solution Expands LFP Battery Production for ESS with KC Certification
8. January 2026LG Energy Solution has announced plans to domestically manufacture lithium iron phosphate (LFP) batteries for energy storage systems (ESS) in South Korea. On November 17, the company held an official event at its Ochang Energy Plant in North Chungcheong Province to mark the initiative. Construction of the new LFP production lines is scheduled to begin at the end of this year, with full-scale operations targeted for 2027. Initial production will start at a scale of 1 GWh, with potential capacity expansion depending on future market demand. ESS batteries and related systems usually require KC Safety certification in order to be approved for import and sale in Korea.
LG Energy Solution is currently the only non-Chinese company with a mass production system for ESS-specific LFP batteries. The company intends to transfer its production expertise from its facilities in Nanjing, China, and Michigan, USA, directly to the Ochang Energy Plant to help develop Korea’s domestic ESS ecosystem. In parallel, it aims to localize the sourcing of LFP battery materials—currently reliant on global supply chains—by collaborating with North Chungcheong Province and domestic suppliers. LFP technology is considered optimal for ESS applications due to its strong cost competitiveness and low fire risk. LG’s LFP products meet UL’s UL9540A fire safety standards and have passed Korea’s NFPC607 tests, demonstrating robust performance under thermal runaway conditions. These safety levels are attributed to LG’s proprietary battery management system (BMS) and integrated design across cell, module, and pack levels.
