About this plant

Commissioned in 2007, the Longma Dam emerges as a noteworthy player in China’s energy landscape, ranking 1193rd among the nation’s power generation facilities with a capacity of 240 MW. This hydro facility contributes a modest 0.01% to the national energy capacity, which totals an impressive 1,603,494 MW, primarily dominated by coal. Longma Dam holds the 204th position among 1000 hydro plants in China, reflecting its role within the broader context of renewable energy generation. The dam is surrounded by several larger hydro plants, including the Gelantan Dam at 390 MW, Jufudu Dam at 285 MW, and Sinanjiang Dam at 201 MW. This cluster indicates a regional focus on hydroelectric power, enhancing the reliability and sustainability of electricity supply in the area. Utilizing state-of-the-art hydroelectric technology, the Longma Dam converts river flow into electricity, contributing to a cleaner energy mix that aligns with China’s long-term environmental goals. Although its share of the national capacity is small, the Longma Dam is integral to the local energy infrastructure, supporting Yunnan Province’s efforts to transition from coal dependency. The ongoing operation of this facility signifies a commitment to developing renewable energy sources and reducing carbon footprints. The local authorities who manage the Longma Dam are continuously exploring ways to enhance its contribution to the grid, and as China’s energy policies evolve, this hydro plant could see increased usage in the future. By integrating renewable sources like hydro power into its energy portfolio, China aims to create a more sustainable and environmentally friendly energy landscape.
