LS Materials, LS Electric sign MOU to develop E-STATCOM grid technology
The two companies will pair LS Electric's power conversion and grid control technology with LS Materials' large-capacity ultracapacitor system.
LS Materials and LS Electric signed a memorandum of understanding on November 9, 2026, to jointly develop and demonstrate E-STATCOM grid stabilization technology, according to datanet.co.kr.
E-STATCOM combines the voltage stabilization function of a STATCOM (static synchronous compensator) with the fast charging and discharging of ultracapacitors.
Under the agreement, the two companies plan to combine LS Electric's power conversion and grid control technology with LS Materials' large-capacity ultracapacitor system. The partnership also aims to localize the system and pursue overseas markets.
Earlier work
In 2024, LS Materials developed LS UltraGrid, described as Korea's first MW-class rack-type ultracapacitor system applicable to E-STATCOM. LS Electric has carried out STATCOM projects totaling 4.7 Gvar in Korea.
