The 1.4 GW Phu Cuong Soc Trang offshore wind farm is a joint venture between Mainstream and local company, the Phu Cuong Group. It is located off the southern coast of Vietnam and will be the largest offshore wind farm in South-East Asia when complete. The wind farm will be developed in two phases; Phase 1 (200 MW) and Phase 2 (1.2 GW).

Phase 1, the first 200 MW of the project has received its Decision on Investment and Investment Registration Certificate (IRC) from the Soc Trang province.

In Development

Mainstream and the Phu Cuong Group entered a joint venture agreement in 2017 to develop the 1.4 GW Phu Cuong Soc Trang Offshore Wind Farm. The wind farm will be developed in two phases; Phase 1 (200 MW) and Phase 2 (1.2 GW).

The project has reached a number of significant milestones to date including:

  • Phase 1, 200 MW included in the government’s Power Development Plan 7;
  • Investment Registration Certificate (IRC) received for Phase 1;
  • Second LiDAR installed on location of Phase 1 and has completed the wind measurement campaign;
  • Site geotechnical investigation and metocean surveys, grid system impact studies, submarine cable systems and turbine foundation designs in progress.

In tandem to desktop analysis, and in support of the sustainable development of this project, the local project development team are engaged with local indigenous people and fishermen to discuss social and economic benefits that could flow from the project from a series of meetings and consultations.

Once operational, it will power over 1.6 million homes and avoid around 1.8 million tonnes CO2 emissions each year.
