What Bs Hanyang Corporation does

BS Hanyang Corporation (주식회사 BS한양) is a privately-held Korean construction, housing development, and energy infrastructure company founded in 1973 and headquartered in Incheon with its principal office at BS Hanyang Tower in Seoul's Songpa-gu district. The company operates across three primary segments: energy (LNG terminals, solar, wind, and biomass power generation), housing development (premium apartments under the SUJAIN brand), and construction (civil, architectural, plant, and infrastructure). As a subsidiary of BS Group, BS Hanyang has delivered approximately 230,000 housing units and completed over 500 construction projects across its 50+ year history. In January 2025 the company was rebranded from Hanyang to BS Hanyang to formalize its integration into the BS Group umbrella, which also spans BS Corporation, BS Asset Management, Solaseado, Sani Garden, Pine Beach/Pine Hills/Pine Park/Solaseado CC, and Yeosu International Port.

The company's core technology stack covers construction engineering (roads, ports, railways, LNG storage tanks), renewable energy systems (solar PV including floating solar, onshore wind, biomass), and proprietary smart home and safety technology. Proprietary assets include the SUJAIN Smart Home 1.0 platform (launched 2020), patented underground parking concrete floor structure technology (Patent No. 10-1948662), green technology-certified dual-reinforced composite waterproofing methods, the concrete filled P-girder method (Construction New Technology No. 956), and the SMART Risk Assessment System deployed across all business sites in 2025 alongside 29 types of smart safety equipment. Operating renewable assets include the 98MW Solaseado solar power plant with 306MWh ESS (commercial operation since January 2020), the 98MW Goheung floating solar plant, the 84MW Haenam onshore wind project, and the Gwangyang Green Energy biomass joint venture. The company has been rated "Very Excellent" in MOLIT safety management evaluations for both 2023 (95.9 points) and 2024 (96.6 points) and holds Korea ESG Green Bond GB1 rating.

BS Hanyang generates revenue through five streams: housing development and sales via the Korean national subscription system (one-time); construction contracting won through competitive bidding for civil, architectural, plant, and infrastructure projects (one-time); renewable energy operations selling electricity to Korea Power Exchange under long-term PPAs (usage-based); LNG terminal operations including storage, regasification, and future hydrogen/ammonia services at Myodo, Yeosu (managed services); and recurring real estate leasing from BS Hanyang Tower (40,896.5 sqm). Key customers include LH (Korea Land and Housing Corporation) for public housing, KEPCO subsidiaries (Korea Southern Power, Korea East-West Power, Korea Western Power) for energy co-investment, Korea Power Exchange as renewable offtaker, GS Energy as LNG partner, Air Products and Linde as hydrogen/ammonia partners, Copenhagen Infrastructure Partners (CIP) as wind partner, TGK as data center partner, and Samsung SDS as AI supercluster partner. The company is recognized as an "Excellent Contractor" by LH and Gyeonggi-do province, with the SUJAIN brand ranked 9th in the K-Brand Index for apartment brands in 2024.

Revenue model

1. Housing Development and Sales: BS Hanyang develops and sells residential apartment units under the SUJAIN brand, generating revenue from the sale of housing units. The company participates in both private housing development and public housing projects (민간참여 공공주택) through LH. Revenue is generated through unit sales to individual buyers via the national subscription system, with prices regulated by the apartment price ceiling system (분양가상한제).
2. Construction Contracting: The company generates revenue through construction contracting for civil engineering, architecture, infrastructure, and plant projects. This includes public works tenders (roads, ports, railways), building construction (commercial and residential), and specialized plant construction (LNG storage tanks). Projects are won through competitive bidding with government agencies and private clients.
3. Renewable Energy Operations: BS Hanyang operates renewable energy assets including the 98MW Solaseado solar power plant (in operation since January 2020) and other floating solar and wind projects. Revenue is generated from electricity sales to the grid (Korea Power Exchange) under long-term power purchase agreements. ESS (306MWh) provides additional revenue through energy storage services.
4. LNG Terminal Operations: BS Hanyang is developing the Northeast Asia LNG Hub Terminal at Myodo, Yeosu (1.1 trillion won project finance secured in April 2025). The terminal will generate revenue from LNG storage fees, regasification services, and potentially hydrogen/ammonia-related services. Construction of tanks 1-2 scheduled for completion by December 2027.
5. Real Estate and Leasing: BS Hanyang Tower (40,896.5 sqm total area) serves as the company's headquarters and also generates leasing revenue from office and retail tenants. The building features one-stop office, green office, and high-tech office facilities available for lease.
