Hai Long offshore wind selects consortium to deliver two offshore substations in Taiwan

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 off the coast of Taiwan.

The sites will deliver more than 1 GW of green wind energy once they are 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 percent, with Northland Power owning 60 percent.

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 Vũng 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, cooperating closely with ISC Consulting Engineers as the primary sub-contractor.

“This is an important step in the delivery of the Hai Long Offshore Wind Farm, a project initiated by Enterprize back in 2013” said Ian Hatton, Founder and Chairman of, Enterprize Energy and its wholly owned subsidiary, Yushan Energy. “This highlights the long-standing commitment needed by companies to ensure future supplies of low carbon energy to people who need it. Enterprize is equally committed to delivery of the Thang Long Offshore Wind Farm south of Binh Thuan Province. I personally have been convinced that Vietnam’s fabrication yards in Vũng Tàu have the globally competitive capabilities to produce the infrastructure needed for offshore wind energy development anywhere in the World. Enterprize committed to fabricate the infrastructure for Thang Long there from the very outset. Consequently, I am delighted that the first engineering contract placed in Vietnam for major equipment fabrication comes from a development which we originated and took forward with partners Northland and Mitsui.”
