SEOUL, January 20 (AJP) - Hyosung Heavy Industries said on Tuesday it has signed an agreement with Germany’s Skeleton Technologies and Japan’s Marubeni to cooperate on the development and commercialization of “e-STATCOM,” a next-generation power-compensation system.

Under the deal, Hyosung Heavy Industries and Skeleton Technologies will jointly develop e-STATCOM through 2027, while Marubeni, a strategic partner of Skeleton, will provide stable supplies of supercapacitors used in the system.

e-STATCOM combines a conventional static synchronous compensator, or STATCOM, with a high-performance energy storage device known as a supercapacitor. The system is designed to adjust power supply and power quality in real time, helping improve grid stability.

Hyosung said global power markets are increasingly in need of advanced stabilization technologies to address supply-demand imbalances stemming from the rapid expansion of AI-driven industries and the growing share of renewable energy sources. The company said e-STATCOM is emerging as essential infrastructure for future energy markets because it can help maintain stable power systems amid sharp fluctuations in demand.

Hyosung Heavy aims to complete development of e-STATCOM in 2027 and pursue South Korea’s first commercialization of the technology. The company has steadily internalized power-stabilization technologies, including STATCOM, to respond to structural changes in electricity markets driven by AI growth and renewable energy expansion.

Hyosung first developed a STATCOM domestically in 2006 and has since led the South Korean market. It commercialized a 150-megavolt-ampere reactive (Mvar) STATCOM in 2015 and installed 400Mvar STATCOM units in 2018 at the Sin Yeongju and Sin Chungju substations, which it said were the world’s largest single-unit installations at the time.

The company has also supplied STATCOM systems to major overseas markets, including the United States, Europe and the Middle East.
