Hyosung Heavy Industries to Cooperate on the Development of Next-Generation Power Stabilization Solution ‘e-STATCOM’

Hyosung Heavy Industries moves to secure next-generation power stabilization technologies to respond to surging electricity demand in the AI era.

Hyosung Heavy Industries announced on the 19th that it has signed a Memorandum of Understanding (MOU) with Germany-based Skeleton Technologies and Japan’s Marubeni Corporation for the development of and business cooperation on e-STATCOM.

Under the agreement, Hyosung Heavy Industries and Skeleton Technologies will combine Hyosung Heavy Industries’ STATCOM (Static Synchronous Compensator) technology, which has been validated in the global market, with Skeleton Technologies’ supercapacitor solutions—ultra-fast charging and discharging devices—and will jointly cooperate on the development of e-STATCOM, a next-generation power compensation system promoted by Hyosung Heavy Industries, through 2027. Marubeni, a strategic partner of Skeleton Technologies, will be responsible for the stable supply of supercapacitors.

Responding to power demand in the AI era, targeting Korea’s first commercialization

e-STATCOM is a next-generation solution that enhances power grid stability by combining conventional STATCOM systems with supercapacitors, high-performance energy storage devices, enabling real-time control of both power supply and power quality.

The global power market is facing increasing demand for power stabilization technologies to address imbalances in power supply and demand driven by the transition to the AI era, as well as to respond to the variability of renewable energy sources such as solar and wind power.

By enabling stable operation of power systems even under highly volatile power demand, e-STATCOM is regarded as essential infrastructure for the future energy market.

Hyosung Heavy Industries plans to complete development in 2027 and pursue Korea’s first commercialization.

Chairman Cho Hyun-joon: “We must become a game changer that reshapes the global power grid”

To proactively respond to changes in the power market driven by the expansion of the AI industry and renewable energy, Hyosung Heavy Industries has long internalized power stabilization technologies, including STATCOM.

Chairman Cho Hyun-joon has stated, “The global power market is entering a ‘super cycle’ as the transition to the AI era coincides with the expansion of renewable energy,” adding, “Hyosung Heavy Industries must build world-class technological capabilities and become a game changer that reshapes the power grid through preemptive development of next-generation power solutions.”

Since successfully developing Korea’s first STATCOM system in 2006, Hyosung Heavy Industries has led the domestic market. In 2015, the company succeeded in commercializing a 150Mvar-class STATCOM, and in 2018 installed 400Mvar-class STATCOM systems—the world’s largest single-unit capacity at the time—at the Shinyeongju and Sinchungju substations.

Based on its technological capabilities, Hyosung Heavy Industries has supplied STATCOM systems not only domestically but also to major overseas markets, including the United States, Europe, and the Middle East, and is evaluated as one of the global top-tier players.
