Longshou II Dam157 MW Hydroelectric

HydroRenewable

Situated in China, the Longshou II Dam stands as a noteworthy facility with a capacity of 157 MW, ranking it 1318th among the 4430 power generation facilities in the country. This dam is the 261st largest hydroelectric power plant out of 1000 hydro plants in China, contributing to the nation’s total capacity of 1,603,494 MW, where coal remains the predominant fuel source. Commissioned in 2004 and operated by Gansu Hexi Hydropower Development Investment Co Ltd, Longshou II employs advanced hydroelectric generation technology to efficiently convert river flow into renewable energy. The dam is strategically located near several other plants, including the GEPIC Zhangye power station, which generates 650 MW from coal, and several hydro facilities such as Gansu Heihe Baopinghe (123 MW), Xiaogushan (102 MW), Dagushan (65 MW), and Erlongshan (50 MW). This clustering of energy production in the region emphasizes the importance of hydropower alongside traditional fossil fuels, as China works towards a more diversified energy portfolio. Despite its relatively modest capacity, Longshou II plays a significant role in supporting local energy demands and contributes to balancing the grid. As China pushes forward with its energy transition goals, Longshou II exemplifies the nation’s efforts to increase the share of renewable energy sources. The plant not only aids in reducing greenhouse gas emissions but also enhances regional energy security, paving the way for a more sustainable future.
