The most continental wind farm project in Southeast Asia will be put into operation in 2023.

Japan's Mitsubishi will invest in a 600-megawatt onshore wind farm project in Laos that will supply electricity to Vietnam.

The company said it had reached an agreement to invest in Impact Energy Asia Development Ltd, the developer of the project, through an intermediate holding company and Thailand's Impact Electrons Siam Group.

Mitsubishi completed the investment through its wholly-owned Hong Kong subsidiary Diamond Generating Asia Ltd, but did not provide further details on the investment.

The wind farm, located in Sekong and Atapeu provinces in southern Laos, will be the first wind farm in Laos and the largest in Southeast Asia.

According to the plan, the project will sell electricity to Vietnam's state-owned power company through dedicated transmission lines within 25 years.

Vietnam needs additional electricity to support its economy, especially during the dry season when hydropower is limited. Mitsubishi explained that the project is expected to help stabilize Vietnam's power system and make its energy structure greener.

The development of wind farms is in line with the 2016 memorandum of understanding between the governments of Vietnam and Laos on power exchange.

According to the Impact Electrons Siam website, the wind farm aims to be commercially operational by 2023.
