The Xilongchi pumped storage power plant (output: 1,224 MW) in China started commercial operation. This plant, which takes advantage of a large difference in elevation of around 700 meters, was delivered as the first pumped storage power plant in China by a consortium of Japanese companies. Its main feature is that although it uses a high elevation drop and is designed for high output, it generates very little noise or vibration. Pumped storage power generation works by pumping water to a higher elevation during slack periods and using the stored water to generate electricity during high-demand periods. In this way it is able to match supply to demand, and this station is contributing to the stable supply of electricity to the Huabei region, including Beijing.
