On December 26, 2024, Unit 2 of the Nam E-moun Hydropower Station in Laos successfully completed its 96-hours trial operation. With this achievement, both units of the Nam E-moun Hydropower Station are now fully operational.

Located in Sekong Province, Laos， the Nam E-moun Hydropower Station is equipped with two vertical Pelton hydro-generator units, with a total installed capacity of 133MW. Once operational, the power station will transmit electricity to the southern power grid of Vietnam via cross-border transmission lines. As the inaugural grid-connected power station within the package project plan for Laos to supply power to the Vietnamese power grid in the southern Laos, the Nam E-moun Hydropower Station will be bundled and transmitted together with the second-phase of Nam E-moun, a 100MW pumped-storage project, and a 50MW floating PV solar project in the future. This development has infused fresh momentum into the energy development and economic growth of both Laos and Vietnam, propelling Laos closer to its aspiration of becoming the "battery of Southeast Asia".

The computer monitoring system of the power station adopts the SSJ-3000 monitoring system of NARI. The host computer utilizes NARI’s IMC integrated platform, which offers a user-friendly interface and straightforward operation. The slave computer is powered by NARI’s self-produced MB40 series PLC, marking the first successful overseas application of this PLC in hydropower projects. The computer monitoring system features a redundant design and an open-system architecture, characterized by high system integration, robust scalability, and ease of operation and maintenance.
