The company plans to deliver 133 EN-171 wind turbines, each with 4.51MW of capacity, for the 600MW project.
IEAD managing director Nat Hutanuwatr said: “As we are making excellent progress in developing the first and largest cross-border wind farm in South-East Asia with a very competitive tariff, we are delighted to welcome Envision to join our exciting journey to deliver zero-carbon electricity.
“Envision’s state-of-the-art technology for the proposed wind turbine solution and its successful execution track record will be key enablers for the project to achieve its objectives reliably and economically.”
The construction works for the Monsoon Wind Project are expected to begin this year, with the wind farm due to begin commercial production in 2025.
Once complete, the project will be the largest wind farm in the Association of South-East Asian Nations (Asean ) region.
IEAD is developing the project, which will deliver more than 1,700GWh of green energy a year once fully operational.
Last year, the company signed a 25-year power purchase agreement with Vietnamese state-owned energy firm Vietnam Electricity.
The electricity generated by Monsoon Wind will be transmitted to central Vietnam through a dedicated 500kV transmission line.
IEAD is also associated with the development of the Xekong Wind Project, another wind farm located next to the Monsoon Project.
Envision Group is a green technology company that delivers wind turbines, smart storage systems and energy management software solutions.
In 2019, MIT Technology Review placed the company in the top ten of its World’s 50 Smartest Companies list.
