Woori Technology Begins Detailed Design for Amhae Offshore Wind Power

Woori Technology announced on the 13th that the procurement of main equipment and major permit procedures for the construction project of the Aphae Offshore Wind Power Plant have been smoothly completed, and detailed design of the power plant is currently underway. The company plans to accelerate construction by simultaneously conducting permit procedures and detailed design of the substructure. The Aphae Offshore Wind Power Plant aims to begin commercial operation in 2027. Once operational, it is expected to become the first privately-led offshore wind power plant in Korea with a capacity exceeding 80MW (megawatts).

The detailed design phase involves planning the layout of transmission lines and generators within the power complex, as well as the design related to substructures, transportation, and installation. During this phase, the construction company will be selected, negotiations for resident compensation will be conducted, and project financing (PF) will be secured before construction begins. Woori Technology has maintained communication with local residents and organizations since the early stages of the project and is currently proceeding with preliminary procedures for PF.

Woori Technology plans to expand its renewable energy business sector focusing on offshore wind power, which has significant market growth potential. Due to site conditions, offshore wind power is more suitable than onshore in Korea. Wind speed and volume are stable, and there are no area restrictions, making the development of ultra-large complexes easier. The company explains that if the Aphae Offshore Wind Power Plant operates successfully, it will be advantageous to expand into additional large-scale offshore wind power complexes domestically.

Woori Technology is conducting offshore wind power projects by applying measurement and control system technology in collaboration with its offshore wind power specialist subsidiary, CGO. In 2012, CGO won the contract for the upper and lower installation works of the 30MW-scale Tamna Offshore Wind Power Plant in Jeju Island, becoming the first company in Korea to complete such construction. CGO is also participating in the Daejeong Offshore Wind Power Project with Korea Southern Power and others. CGO possesses various core technologies in offshore wind power development, transportation, installation, and design.

A Woori Technology official stated, “The Aphae Offshore Wind Power Project has completed cultural heritage surveys and maritime traffic safety assessments, with only some final permit procedures such as marine area use impact assessments remaining.” He added, “To expedite construction, detailed design and contractor selection are being conducted simultaneously, and based on the trust built with Aphae-eup residents, resident consultations are expected to conclude smoothly.”

He continued, “The Aphae Offshore Wind Power Plant overcame the disadvantage of high construction costs in offshore wind power projects by optimizing costs during site selection, design, and construction stages.” He said, “Upon commercial operation, Woori Technology expects additional annual sales of over 55 billion KRW in the wind power business sector, in addition to existing businesses such as nuclear power and SOC. The company’s total annual sales are expected to exceed 100 billion KRW.”
