Overview
Three Gorges Dam is a 22,500 MW hydroelectric power plant in China, the world's largest power station by capacity. It generates clean energy for the Yangtze River region.
Three Gorges Dam is a massive hydroelectric power plant located on the Yangtze River in China. With a capacity of 22,500 MW, it is the largest power station in the world by installed capacity. The plant plays a critical role in China's energy grid, providing renewable electricity to millions of households and industries across the region. The facility operates as a run-of-river hydroelectric plant, utilizing the flow of the Yangtze River to generate electricity. Its 32 main turbines and two smaller generators produce an average annual output of over 100 TWh. The plant's design incorporates advanced turbine technology to maximize efficiency and minimize environmental impact. Three Gorges Dam significantly reduces China's reliance on coal-fired power, cutting CO2 emissions by an estimated 100 million tons annually. It also provides flood control and navigation benefits along the Yangtze River. The plant's operational status is fully active, contributing to China's renewable energy targets and global climate goals.
Environmental context
As a hydroelectric plant, Three Gorges Dam produces no direct CO2, SOx, or NOx emissions, making it a low-carbon energy source. However, the dam's construction flooded large areas, displacing communities and altering local ecosystems. The reservoir's methane emissions from decomposing vegetation are a consideration. The plant's location on the Yangtze River supports regional water management and reduces air pollution from fossil fuel alternatives.
