Hyosung Secures First Australian ESS Project, 142.5 Billion Won EPC
Hyosung Heavy Industries announced its first energy storage system (ESS) project in Australia, signing an EPC contract worth 142.5 billion won to build a 100 MW / 200 MWh ESS in the Tangkam region of Queensland. Commercial operation is slated for the end of 2027.
The deal follows a wave of global orders for the company. Hyosung said it also secured a US power equipment supply contract valued at about 78.7 billion won, the largest such contract since its founding, and a 2.9 billion won long-term high-voltage transformer contract in Finland. The Tangkam ESS marks a concrete win in its international expansion.
Australia’s move to expand ESS capacity is part of a broader grid-stability push as the government aims to raise the share of renewable energy in the electricity mix. Officials target about 82 percent renewable energy by 2030, a backdrop that helps explain the timing and scale of Hyosung’s Australian project.
ESS projects store surplus renewable energy and release it when demand rises or when generation falls, helping balance supply and stabilize frequency on the grid. Hyosung’s project will feature its own battery management software, enabling integrated control of the battery and connected power equipment.
Hyosung Chairman Cho Hyun-joon has positioned Korea as a supplier of end-to-end grid solutions. He has emphasized field engagement, including meetings with Australian business leaders and delegations from the Australian Business Council earlier this year to explore cooperation—all contributing to the Tangkam contract.
Cho has said future competitiveness in the power sector will hinge on solutions that can control the entire power grid, and he intends to combine HVDC, high-voltage transformers, circuit breakers, ESS and STATCOM capabilities to offer a total-solution package and boost Korea’s energy-equipment exports.
The company plans to push ahead with HVDC and STATCOM technology to expand its footprint in Australia’s grid market. Australia’s national grid modernization program, estimated at about A$200 billion, is driving demand for large-scale power infrastructure, including ESS, HV equipment and related control systems.
Hyosung has built a recognized presence in Australia over the past decade as a turnkey supplier for the transmission market, including being a leading provider of transformers. The group has secured long-term HV equipment contracts with both government-backed and private energy players, including projects tied to the Energy Connect transmission link that connects South Australia and New South Wales.
