The investor, Vung Ang II Thermal Power LLC (VAPCO), has completed necessary procedures for the $2.2-billion project to go ahead, deputy chief executive officer Hoang Trong Binh told the Vietnam Finance newspaper.
Vung Ang 2, largely owned by Mitsubishi Corp and Korea Electric Power, is scheduled to start commercial power generation in the third quarter of 2025, Binh said.
South Korea's Doosan Heavy Industries & Construction and Samsung C&T were among the construction contractors involved in the project, he added.
A VAPCO spokesman said construction work on the project would start on December 5.
Vietnam's Deputy Prime Minister Le Van Thanh in a statement on Monday called on its miners and relevant authorities to boost domestic coal production as the country grows more reliant on imports.
