In May 2025, Gansu Province will launch its first large-scale pumped storage power station, marking a significant advancement in energy storage capabilities. This project will enhance the stability of the power grid and contribute to the growth of renewable energy sources.
The pumped storage station is located in the Gansu Province near the Hexi Corridor, covering an area of approximately 8,000 mu, which is equivalent to about 5.3 square kilometers. The facility will consist of 76 generating units capable of producing a total installed capacity of 2,500 megawatts.
This pumped storage power station will have a reservoir with a capacity of 360 million cubic meters. It will include the installation of 220,000 kilowatt units designed to effectively manage electricity supply and demand, allowing for a smooth integration of renewable energy into the grid.
Upon its completion, the station is expected to generate around 4.5 billion kilowatt-hours of electricity annually. This output is anticipated to reduce carbon emissions by approximately 40 million tons per year, equivalent to planting around 2 million trees.
The project is set to begin construction in September 2024, with an estimated completion time of 150 days. It aims to tackle challenges related to energy demand fluctuations and improve the overall energy balance within the region.
As one of the first large-scale pumped storage power stations in Gansu, this project will play a crucial role in linking renewable energy sources to the grid, allowing for enhanced power generation capabilities and grid stability.
The facility will also support the integration of advanced technologies, including intelligent grid management systems, to optimize power distribution and improve energy efficiency.
Overall, this development highlights Gansu’s commitment to advancing its energy infrastructure and supporting the transition to a more sustainable energy future.
