CGN Oudom Xay Solar Power Project info by Hobo Maps - Go to Solar Power Projects Page - - - HOME

The 1,000 megawatt (MW) CGN Solar Power Project in Xay and Namor districts of Oudom Xay Province, Lao PDR was officially completed and commissioned on December 13 2025.

The solar farm is part of the Northern Laos Interconnected Clean Energy Base that integrates solar, wind, and biomass power projects across Oudomxay, Luang Namtha, and Phongsaly provinces with plans to establish northern Laos as a regional clean-energy hub.

The Project is situated on 2,090 hectares in the area of seven villages in Xay and Namor districts of Oudom Xay Province.

Phase I of the 1,000 MW project is expected to generate about 1,700 gigawatt hours (GWh) of output annually.

The Project's initial output is to be transmitted via an existing power line that transfers power from Laos to China’s Yunnan Province. Output will additionally be transmitted to Yunnan Province by the under-construction China-Laos 500 kilovolt (kV) power grid interconnection after it becomes operational. As of February 2026, this 500 kV interconnection project has reached 100 percent construction completion and is expected to begin transmitting power in April 2026.

The Project is initially based on a memorandum of understanding (MOU) signed between China General Nuclear Power Group and the Lao government in October 2022 that took place during the China-ASEAN Expo held in Nanning, Guangxi province.

In September 2023, China General Nuclear Power Group signed an Agreement for Renewable Energy Project development agreement with the government of Laos to develop a renewable energy base in the north of the country. The base is planned to incorporate wind, solar, hydro and energy storage capabilities.

A concession agreement for the Project was signed in September 2024. We are unsure of the concession terms at this time but most concession agreements in Laos for power production are for terms of about 25 years with complete ownership reverting to the Lao government on conclusion.

Combined Development of Solar and Wind power Projects by CGN at the same Location

Chinese state-owned nuclear power company China General Nuclear Power Group (CGN) is also developing a wind power project not far from the CGN solar power projects discussed above on this web page in Oudom Xay province of northern Lao PDR. This would be the first development of both wind and solar power projects in Laos by the same company in the same general area.

By developing multiple clean-energy complementary projects the company plans to share transmission facilities and address the intermittency challenges of renewable energy sources while enhancing the stability of cross-border electric power transmission.

In January 2026 we aren't sure if construction of the Phase 2 wind power project has begun yet but based on the history of CGN's solar power Phase 1 development, once construction begins it won't take long for completion.
