Hyosung Heavy Industries is accelerating efforts to ramp up its presence in Japan after landing a series of energy storage system (ESS) projects since its inaugural market entry.
Hyosung Heavy Industries said on May 27 the company struck an 11 billion won high voltage grid-connected energy storage system (ESS) EPC (engineering, procurement and construction) project with a Japanese energy developer.
The project calls for building 100MW/40MWh high-voltage ESS units in five Japanese areas in Oita, Kumamoto, Yamaguchi, Okayama and Miae.
Hyosung Heavy Industries is responsible for designing a whole system and supplying major equipment. The company is expected to offer O&M services for a maximum of 20 years after it is dedicated.
The winning order is the latest of a series of orders Hyosung Heavy Industries has landed in the first year of its entry into the Japanese market.
In February, Hyosung Heavy Industries won a 48.6MW/228MWh special high-voltage grid-connected ESS EPC project in the Shiranuka area in Hokkaido.
The cumulative value of orders the company landed in the first half of this year stood at 64 billion won, the best-ever figure among Korean electric equipment makers.
In particular, Japan is considered a market with greater entry barriers since it has different power electric frequencies and difficult power grid standards.
Hyosung Heavy Industries has proved its capability of carrying out projects in all power grid conditions, as the company was awarded high-pressure distribution network projects in the Kansai and Kyushu areas in the central and southern regions of Japan following the landing of a special high-voltage transmission grid connectivity project in Hokkaido.
Hyosung Heavy Industries aims to expand its presence in the global ESS market by using the Japanese market as a stepping stone.
The company plans to ramp up its overseas ESS business by targeting countries seeking renewal energy expansion.

Hyosung Heavy Industries Unveils Next-Generation SF6-Free 145kV Circuit breaker
On April 1, Hyosung Heavy Industries announced that it has developed and will begin mass production of a 145kV circuit breaker that uses dry air instead of SF₆ gas for the first time in Korea.
SF₆ is known as a gas that withstands high voltage conditions inside a circuit breaker and effectively interrupts electrical current. Due to its high Global Warming Potential (GWP), however, efforts to replace this gas are increasing.
Hyosung Heavy Industries has enhanced its greenhouse gas reduction effect by applying dry air consisting of nitrogen(N₂) and oxygen(O₂) instead of SF₆ to its newly-developed 145kV circuit breaker.
By incorporating vacuum circuit breaker technology, Hyosung Heavy Industries secured both insulation and current interruption performance while enabling stable operation of the circuit breaker.
Hyosung Heavy Industries is the first in Korea and the world’s second to apply both technologies to a 145kV circuit breaker based on STL (Short-Circuit Testing Liaison) standards, an international accredited testing laboratory consortium.
The European Union (EU) revised its fluorine-based greenhouse gas (F-gas) regulations in 2024, progressively tightening restrictions on fluorinated greenhouse gases including SF₆.
Accordingly, as Europe accelerates the adoption of alternative technologies, the related market is also growing.
According to market research firm Business Research Insights, the global SF₆-free circuit breaker market is forecast to grow from approximately $5.4 billion in 2024 to more than $7.4 billion by 2033.
Hyosung Heavy Industries plans to expand its SF₆-free circuit breaker product lineup to the high-voltage segment.
The company also aims to accelerate its push into the next-generation power equipment market in line with tightening global environmental regulations and growing demand for power infrastructure transition.
