Overview
Yunnan Gaohe River 4th Level is a 20 MW hydroelectric power plant in China's Yunnan province. It harnesses the Gaohe River for renewable electricity generation.
Yunnan Gaohe River 4th Level is a hydroelectric power plant located in Yunnan province, China. With a capacity of 20 MW, it is a small-scale facility that contributes to the region's renewable energy portfolio. The plant is operational and utilizes the flow of the Gaohe River to generate electricity. Hydroelectric power plants like this one operate under China's national energy regulations, which prioritize renewable energy development. The facility uses run-of-river or reservoir-based technology typical for small hydro projects in mountainous regions. Yunnan's abundant water resources make it a key area for hydropower generation. The plant supports local grid stability and provides clean energy to surrounding communities. Its small capacity means it has a lower environmental footprint compared to larger dams, but it still requires careful management of water flow and aquatic ecosystems. The facility plays a role in China's transition to low-carbon energy sources.
Environmental context
The plant's hydroelectric generation produces no direct CO2, SOx, or NOx emissions, making it a low-carbon energy source. However, its operation can affect local river ecosystems through altered water flow and potential impacts on aquatic habitats. Located in a mountainous region of Yunnan, the facility benefits from high rainfall and steep gradients, which are ideal for hydropower. The small scale (20 MW) reduces the extent of reservoir flooding and downstream disruption compared to larger projects.
Frequently asked questions
The plant is located in Yunnan province, China, near the Gaohe River at coordinates 25.0808 N, 97.7181 E.
The plant has a capacity of 20 megawatts (MW), classifying it as a small hydroelectric facility.
Hydroelectric plants convert the kinetic energy of flowing water into electricity using turbines and generators. Water flow drives turbines, which spin generators to produce power.
Hydroelectric plants in China must comply with national renewable energy policies, water resource laws, and environmental impact assessments. The government promotes small hydropower as part of its clean energy strategy.
Small hydro plants have lower environmental impact than large dams, but they can still affect river flow, fish migration, and local ecosystems. Proper siting and mitigation measures are required to minimize harm.
