Hai Long Offshore Wind selects consortium to deliver two offshore substations in Taiwan

13 October 2021

Yushan Energy, a subsidiary of low carbon energy developer Enterprize Energy, and Canadian independent power producer Northland Power have selected a Vietnamese consortium led by Semco Maritime and PTSC M&C to construct two offshore substations for the Hai Long 2 and Hai Long 3 wind projects. Located off the Taiwanese coast, the sites will deliver more than 1 GW of green wind energy when commissioned in 2025-26.

Yushan Energy, a consortium led by Enterprize Energy and Mitsui & Co, are co-developers of the Hai Long Offshore wind portfolio, owning 40%, with Northland Power owning 60%.

The agreement includes design, engineering, procurement, construction, and commissioning of the two offshore substations. The substation jackets will be manufactured at PTSC M&C’s yard facilities in Vung Tàu, a port city in south Vietnam, at the heart of the country’s offshore oil and gas industry. The deal represents the largest offshore substation contract awarded for a Taiwanese project to date, and the first in Vietnam.

The consortium and ISC Consulting Engineers will execute the project from Q4 2021, with offshore installation planned in 2024 and commissioning in 2026. Semco Maritime will lead the consortium with PTSC M&C, co-operating with ISC Consulting Engineers as the primary sub-contractor.

Ian Hatton, founder and chairman of, Enterprize Energy and its wholly owned subsidiary, Yushan Energy, said: “This is an important step in the delivery of the Hai Long Offshore Wind Farm, a project initiated by Enterprize back in 2013. This highlights the long-standing commitment needed by companies to ensure future supplies of low carbon energy to people who need it”.
