HD Hyundai Heavy Industries wins contract for 500-MW offshore substation in Taean

HD Hyundai Heavy Industries has signed a contract to build an offshore substation for a wind farm off Taean, South Chungcheong Province. The project covers engineering, procurement, fabrication, installation and commissioning for Taean Wind Power. The substation will help transmit electricity from a 500-megawatt offshore wind farm to shore.

Taean Wind Power is a joint venture between Vena Energy, Copenhagen Infrastructure Partners and Korea Western Power.

HD Hyundai Heavy Industries won the project after signing a front-end engineering design contract in March and a preferred supplier agreement in July.

The company received basic design approval from DNV in 2025 for its self-developed 500-megawatt offshore substation model.

It completed detailed design verification in August, marking the first offshore substation project in Korea to receive international certification for design suitability and safety under global regulations and standards.

HD Hyundai Heavy Industries said it plans to use the Taean project to explore further cooperation on future domestic offshore wind projects with Vena Energy, CIP and Korea Western Power.

HD Hyundai Heavy Industries has signed a contract to build an offshore substation for a wind farm in waters off Taean, South Chungcheong Province, as it expands its presence in the offshore wind market.

The company announced on Friday that it recently signed a contract with Taean Wind Power to carry out the engineering, procurement, fabrication, installation and commissioning of an offshore substation for the wind farm.

Taean Wind Power is a joint venture between Singapore-based renewable energy company Vena Energy, Danish investment and development firm Copenhagen Infrastructure Partners (CIP) and state-run Korea Western Power.

An offshore substation is a key facility that transmits electricity generated by turbines at an offshore wind farm to shore.

The offshore substation to be built in Taean will step up the voltage of electricity generated by a 500-megawatt wind farm before transmitting the power to shore.

HD Hyundai Heavy Industries secured the project through a series of agreements, signing a front-end engineering design contract in March, followed by a preferred supplier agreement in July. The two companies finalized the main contract after further negotiations, paving the way for the project to move forward.

“Building on our accumulated offshore plant expertise, we will carry out the offshore substation project reliably,” a company official said. "We will also continue to seek new business opportunities in the renewable energy sector and strengthen our competitiveness in the market."

The company obtained basic design approval from Norwegian classification society DNV in 2025 for its self-developed 500-megawatt offshore substation model.

It also completed detailed design verification in August, marking the first time an offshore substation project in Korea had received international certification for design suitability and safety under global regulations and standards.

HD Hyundai Heavy Industries said it has demonstrated its technological capabilities through a range of offshore plant and offshore wind projects, expanding its offshore wind business by applying expertise developed through its offshore plant operations.

The company added that it plans to build on the Taean project to explore opportunities for further cooperation on future domestic offshore wind projects with Vena Energy, CIP and Korea Western Power.

现代重工（HD Hyundai Heavy Industries）已签署合同，将在忠清南道泰安市附近海域建造一座海上风电场的变电站。该项目涵盖泰安风电的工程设计、采购、制造、安装和调试。该变电站将帮助把一座500兆瓦海上风电场的电力输送到岸上。

泰安风力发电公司是 Vena Energy、哥本哈根基础设施合作伙伴和韩国西部电力公司的合资企业。

HD 现代重工在 3 月份签署了前端工程设计合同，7 月份签署了优先供应商协议，最终赢得了该项目。

该公司于 2025 年获得了 DNV 对其自主研发的 500 兆瓦海上变电站模型的基本设计批准。

该项目于 8 月完成了详细设计验证，成为韩国首个根据全球法规和标准获得国际认证的海上变电站项目，证明其设计符合全球法规和标准，且安全可靠。

HD 现代重工表示，计划利用泰安项目，与 Vena Energy、CIP 和韩国西部电力公司进一步探讨未来在国内海上风电项目上的合作。

HD 现代重工已签署合同，将在忠清南道泰安附近海域为一座海上风电场建造海上变电站，以扩大其在海上风电市场的业务。

该公司周五宣布，最近与泰安风力发电公司签署了一份合同，负责该风电场海上变电站的工程设计、采购、制造、安装和调试。

泰安风力发电公司是由新加坡可再生能源公司 Vena Energy、丹麦投资开发公司哥本哈根基础设施合作伙伴 (CIP) 和韩国国营西部电力公司合资成立的。

海上变电站是将海上风电场涡轮机产生的电力输送到岸上的关键设施。

即将在泰安建造的海上变电站将提升500兆瓦风电场产生的电力电压，然后再将电力输送到岸上。

现代重工通过一系列协议最终拿下该项目，3月份签署了前期工程设计合同，7月份又签署了优先供应商协议。两家公司经过进一步谈判后最终敲定了主合同，为项目推进铺平了道路。

公司一位负责人表示：“凭借我们积累的海上电站专业技术，我们将可靠地完成海上变电站项目。同时，我们将继续在可再生能源领域寻求新的商机，并提升市场竞争力。”

该公司于 2025 年获得了挪威船级社 DNV 对其自主研发的 500 兆瓦海上变电站模型的基本设计批准。

该项目还在 8 月份完成了详细设计验证，这标志着韩国海上变电站项目首次根据全球法规和标准获得了设计适用性和安全性的国际认证。

HD 现代重工表示，公司已通过一系列海上工厂和海上风电项目证明了自身的技术能力，并通过应用海上工厂运营中积累的专业知识，扩大了海上风电业务。

该公司补充说，计划以泰安项目为基础，探索与 Vena Energy、CIP 和韩国西部电力公司在未来国内海上风电项目上进一步合作的机会。
