Tad Sakoi (Tadsakoi / Tatsakoi / Tad Sakhoi) Dam Hydropower Info by Hobo Maps - Go to Hydropower Projects Page - - - Home
Tad Sakoi Hydropower Project is located in Sepon District, Savannakhet Province of Lao PDR near the Laos-Vietnam border.
According to a Sept. 2016 CDM filing for carbon credits, the project is located in Sepon District of Savannakhet Province, Lao PDR at coordinates 16°43'30.0"N 106°14'37.0"E (16.725000, 106.243611) as seen in satellite image below. But this old satellite image doesn't show any activity at the site location.

The US$ 55 million Tad Sakoi hydropower project will have a capacity of 30 MW.
The completed project is to operate under a concession agreement with the Lao government for a fixed period of years.
The project began construction in 2013 by Daosavan Company (Daosavanh Investment and Construction Group Co., Ltd.) (DICG).
In 2015 B.Grimm Power Limited (Thailand) conducted a study on the Tad Sakoi hydropower project which identified its potential for power generation to supply electricity for Savannakhet province.
Subsequently in 2019 B.Grimm signed an agreement with Daosavan Company to jointly develop the Tad Sakoi hydropower project. The two firms began construction but the project was delayed to ensure it complied with revised Lao national technical standards.
B.Grimm expected the Tad Sakoi hydropower project to come online in 2022 according to their promotional chart below but in year 2026 we still have no notice of completion or progress report.

Tadsakoi is not B.Grimm's first hydropower project in Laos as they have already completed construction of the Xenamnoy 2 and Xekatam 1 hydropower plant in Champassak province, the Nam Che 1 dam in Xaysomboun province and the Nam Khao project in Xieng Khouang.
A 2025 report by an agency in Vietnam indicates Tad Sakoi HPP has submitted a request for its power production to be sold and exported to Vietnam. In 2026 now seem to be waiting for a response but the report has Bo Y substation as the place where transmission would go to if approved.
This same report lists a similar request by a 15 MW Tad Sakoi Upper hydropower project. We have no info about this project and are unsure if it exists.
