80MW Nam Bong PV Station in Vientiane Enters Full Operation, Setting New National Benchmarks in Laos

A large-scale concentrated photovoltaic facility backed by Yunnan Energy Group has secured full grid connection in Nam Bong, Vientiane of Laos, setting fresh domestic records for single-site installed and energy storage capacity across the country’s renewable power sector and marking tangible progress in bilateral China-Laos energy cooperation under the Belt and Road framework.

The 80-megawatt Nam Bong solar farm now runs on commercial terms after synchronising with Laos’ national main power grid, delivering steady electricity supplies for central Laos and the capital Vientiane while lifting operational stability for the grid system run by Electricite du Laos. Annual power generation from the installation stands at 145.6 million kilowatt-hours with an annual utilisation rate hitting 1,437.5 operating hours. Its green credentials translate into measurable environmental gains, cutting annual carbon dioxide emissions by roughly 132,800 tonnes alongside 16.19 tonnes of sulphur dioxide and 24.39 tonnes of nitrogen oxide each calendar year.

Beyond emission reduction targets, the project delivers sustained social and fiscal advantages for local communities. Continuous construction and daily operation generate abundant local job openings, with recurring tax revenue and concession fees channelled into state coffers every year. Localised training for equipment maintenance and operational services is embedded into routine management to nurture domestic green technical talent, underpinning Laos’ nationwide low-carbon roadmap and cross-border electricity export agenda.

Developed as another landmark overseas renewable asset under Yunnan Energy Group’s global layout, Nam Bong PV follows the 50.1MW Sepangphi solar scheme as the second major concentrated photovoltaic plant successfully hooked up to Laos’ core national grid. Rooted in China’s mature photovoltaic industrial advantages and cross-border energy connectivity initiatives, the scheme opens up fresh market space for the developer’s overseas new-energy expansion while solidifying practical bilateral collaboration to fuel regional economic growth across the Mekong sub-region.

Further coordinated energy linkage schemes between China’s Yunnan province and Laos remain in the pipeline to unlock more renewable development potential for the Indochina peninsula.
