Doosan Heavy Industries & Construction

What Doosan Heavy Industries & Construction does

Doosan Enerbility (formerly Doosan Heavy Industries & Construction) is a South Korean publicly listed (KRX:034020) heavy-industrial and energy infrastructure company headquartered in Seongnam-si, with operating roots in Changwon. Founded in 1962 and rebranded as Doosan Enerbility to reflect a strategic pivot toward eco-friendly energy, the company manufactures large-scale power generation equipment — including gas turbines (Korea's first domestically developed), nuclear power plant components, thermal and combined cycle equipment, hydroelectric and pumped-storage systems — alongside water treatment and desalination infrastructure. It also develops wind power solutions, small modular reactors (SMRs), hydrogen energy systems, and energy storage systems (ESS), supported by advanced material manufacturing capabilities including 3D printing and heavy castings/forgings.

The company monetizes through hardware sales of power plant equipment, long-cycle EPC contracts for power and water infrastructure, plant services and MRO across its installed base, and specialized industrial material manufacturing. Revenue is recognized over multi-year project durations via direct enterprise field sales targeting utilities, independent power producers, governments, and industrial customers globally, with a distribution network spanning Doosan Skoda Power and Doosan Lentjes in Europe, Doosan GridTech in the Americas, and Doosan Power Systems Arabia in the Middle East. With 5,001-10,000 employees, the company has signed multiple major contracts in December 2025 across offshore wind (KRW 575bn with Yawol Offshore Wind Farm Co.), gas turbines for a U.S. technology company, Qatar combined cycle power plant components, and SMR core materials for X-energy — signaling expansion into renewables, SMRs, and hyperscaler-driven power demand.
