What is the most powerful hydroelectric project in the world?

The Three Gorges Dam in China stands as the most powerful hydroelectric project in the world, a distinction it achieves due to its considerable installed capacity, which is approximately 22,500 megawatts. This massive capacity allows the dam to generate a substantial amount of electricity, significantly impacting the energy supply for the region and the country.

Construction of the dam began in 1994, and it became fully operational in 2012. The dam not only plays a critical role in energy production but also aids in flood control and improving river navigation along the Yangtze River. Its scale is unmatched, both in terms of physical size and electrical output, making it a pivotal engineering achievement.

While other notable projects like the Itaipu Dam possess significant capacities and contributions to energy production, none match the overall power output of the Three Gorges Dam. This unique position solidifies the dam's reputation as the largest hydroelectric power station in the world by installed capacity.
