Nam Yeim Dam Hydropower Info by Hobo Maps - Go to Hydropower Projects Page - - Home

Nam Yeim (Yiem) Hydropower project is located in Mok District, Xieng Khouang Province of northern Lao PDR.

Nam Yeim Hydropower project is developed by Phongsubthavy Group in year 2025 with intent to sell output to Vietnam when the project is completed.

The project is to have 10.2 MW capacity.

A web search found that Nam Meng Electric Co., Ltd. has filed a 2020 report regarding work it will do for a project under the name Nam Yeim Hydropower Sole Co. Ltd. We assume that this entity may be the owner of the project but it needs confirmation.

Nam Yeim Hydropower project is probably located somewhere on the Mok District map below but we aren't sure where.

Nam Yeim project construction images below from 2022 or 2023 where construction seems quite far along already.

The project penstock will be about 1738 meters long with wall thickness varying from 10 mm to 22 mm.

Various news reports in June 2021 reported that Electricity of Vietnam (EVN) has exchanged power purchase contracts with Phongsubthavy Group for the Nam Yeuang hydropower plant cluster, the Nam Mo 2 project, Nam Tai, Nam Sak, Nam Sao and Nam Chao hydroelectric plants. Since Nam Yiem HPP is probably located close to these plants, it might be easy to add output from it to this 220 kV export transmission line.
