Recently, Unit 2 of the State Grid Xinyuan Hebei Yixian Pumped Storage Power Station successfully completed a 15 day trial operation assessment and was officially integrated into the power grid for power generation, effectively improving the overall peak shaving, voltage regulation, and resource regulation level of the North China Power Grid.

The total investment of the power station is 8.022 billion yuan, with a total installed capacity of 1.2 million kilowatts. The planned and designed annual pumping capacity is 2.409 billion kilowatt hours, and the annual power generation is 1.807 billion kilowatt hours. Keywords: pumped storage, North China Power Grid

At present, the installation and commissioning work of Units 3 and 4 of the power station is progressing in an orderly manner. After all four units are connected to the grid for operation, about 126000 tons of standard coal can be saved annually, and carbon dioxide emissions can be reduced by about 213000 tons, with significant ecological and environmental benefits.Editor/Gong Ziwei
