Xenamnoy 1 Hydropower project
Run-of-river power on the Xenamnoy
The project uses the flow of the Xenamnoy River in southern Laos to generate electricity. The plant has a capacity of 14.8 MW and feeds around 85 GWh into the power grid each year. The electricity is fed into the interconnected grid of Laos and Thailand. It is expected to reduce emissions by an average of 47,558 tons of CO2e per year by displacing fossil power generation.
Project goals
The project reliably supplies renewable electricity to the Laotian grid and the grid connected to Thailand. It replaces electricity from mainly thermal power plants and thus reduces greenhouse gas emissions. It supports electrification in Laos, increases net exports and reduces net imports of electricity. In addition, local social and infrastructural improvements are planned.

Economic and social benefits
- 1
Workplaces
Numerous local jobs were created during the construction phase and a number of long-term positions were created during operation.
- 2
Water supply
A water program with wells and pumps supports the supply of water to the villagers.
- 3
Infrastructure
Roads for construction have been improved; the electricity transmission system is also being expanded and communication stations supplied with electricity.
- 4
Power access
Feeding into the regional grid improves the local supply and supports electrification.
- 5
Wood substitute
More electricity can reduce the use of firewood and reduce damage to vegetation.
- 6
Religion
The project sponsor built a new temple and takes into account the religious needs of the community.
- 7
Agriculture
Resources for an agricultural fund and technical support are intended to promote agricultural technologies in the villages.
Global climate significance
CO₂ reduction
An average of 47,558 tons of CO2e per year are avoided because renewable electricity replaces fossil fuel generation in the grid.
Fossil replacement
The project displaces generation from thermal power plants, which dominate the Thai-Lao interconnection.
Network connection
Feeding into the Laotian-Thai interconnected grid increases net exports from Laos and reduces net imports.
Low emissions
No fuels in operation; no reservoir emissions are recognized for this run-of-river power plant.
Conclusion
A compact run-of-river power plant supplies renewable electricity to a regional grid and reduces emissions. At the same time, it strengthens local infrastructure and supply - from water to transport - in the project region.
