What Soosan Industry does
Soosan Industry ((주)수산인더스트리) is a South Korean specialized power plant maintenance and construction services provider headquartered in Gangnam-gu, Seoul. The firm delivers preventive maintenance, repair, and equipment services across three vertical segments — nuclear power plants (registered as a qualified KHNP supplier at Kori, Saeul, Hanul, and Shin-Wolsong), thermal power plants (Dangjin, Boryeong, Youngheung, Donghae, Bukpyeong, Chuncheon, among others), and renewable energy facilities (Daegu Green Power, photovoltaic sites). Its core technology portfolio centers on proprietary electromechanical tooling for reactor coolant pumps, high-pressure feedwater heaters, valve packing, belt conveyor inspection via thermal imaging, induction motor management, and confined-space safety systems, with at least 10 patent applications filed across these areas. The business also includes electrical construction and full-scope plant construction for power generation facilities.
The company monetizes primarily through enterprise B2B service contracts with Korean utility operators — a direct sales motion with no intermediaries. Revenue streams are split between recurring professional services for maintenance (turbines, reactor coolant pumps, generators, electro-mechanical equipment) and one-time construction engagements for new plant builds and expansions. Pricing is contract-based and not publicly disclosed. Go-to-market is reinforced by a high-bar certification stack: ISO 9001 (2021), ISO 14001 (2021), ISO 45001 (2019), Korean Power Industry Technical Standards Qualification (2019), and the Nuclear Supply Chain Quality Management System Certification (2024), which together form the regulatory gating for KHNP and KEPCO-affiliate procurement.
Soosan Industry completed its KOSPI listing on August 1, 2022, issuing 5,715,000 shares at KRW 35,000 per share for a KRW 350 billion post-money valuation, with Samsung Securities as lead underwriter. The company is led by Representative Director Han Bong-seop and Group Chairman Jung Seok-hyun, and operates four wholly-owned subsidiaries — 수산ENS (energy services), 수산INT (IT), 수산홈텍 (home textiles/services), and 수산세보틱스 (biotechnology) — that extend the corporate footprint beyond core plant maintenance. Its geographic footprint remains concentrated in South Korea with no disclosed international operations.

Soosan Industry competitors and assessment
Company assessmentBroad incumbents
- Framatome: Framatome is a France-based nuclear services and equipment company providing reactor services, fuel, and instrumentation to global utilities. Comparable to Soosan in servicing PWR fleets and reactor-component maintenance, and a potential international expansion benchmark or competitor.
- POSCO Engineering & Construction: POSCO E&C is a Korean EPC contractor active in thermal and renewable power plant construction, with growing services capabilities. It overlaps with Soosan's plant-construction and renewable-energy maintenance lines, particularly for biomass and solar facilities.
- KEPCO Engineering & Construction (KEPCO E&C): KEPCO E&C is the engineering subsidiary of Korea Electric Power Corporation, specializing in nuclear plant design, construction, and lifecycle services. It is a natural competitor for high-value nuclear engineering and modification work and shares Soosan's reliance on KHNP as a primary customer.
- Hyundai Engineering & Construction: Hyundai E&C is one of Korea's largest EPC contractors with extensive power-plant construction references (thermal and nuclear). It competes with Soosan in the plant-construction and electrical-construction revenue stream, though it does not specialize in MRO services.
- Babcock & Wilcox Enterprises: Babcock & Wilcox is a US-based provider of thermal power generation equipment and services, including boiler and cooling-system MRO. It is a relevant international comparable for Soosan's thermal-plant maintenance business, though it does not operate in the Korean nuclear market.
- Doosan Enerbility (formerly Doosan Heavy Industries): Doosan Enerbility is Korea's largest power-generation equipment OEM and a major aftermarket services provider, supplying turbines, generators, and plant construction while also performing MRO across nuclear and thermal. It overlaps with Soosan's turbine and generator maintenance scope but competes from a much broader equipment-manufacturing base.
- Westinghouse Electric Company: Westinghouse is a leading global nuclear services provider offering fuel, outage, engineering, and component-repair services to PWR operators including KHNP. It is a benchmark international peer for Soosan's nuclear-MRO scope and represents the type of multinational competitor that could enter the Korean market over time.
Direct peers
- KPS Corp (Korea Plant Service & Maintenance): KPS Corp is Korea's largest dedicated power-plant maintenance company, listed on KOSDAQ, providing turbine, generator, and balance-of-plant MRO services to KEPCO and KHNP. It is the closest direct competitor to Soosan in nuclear-qualified maintenance and shares the same KHNP customer base and qualified-supplier framework.
