The Sichuan Provincial Development and Reform Commission announced that the Sichuan Mianzhu Pumped Storage Power Station has received official approval, making it the first large-scale load-side pumped storage project in Sichuan to be approved since the implementation of China’s Energy Law.
The power station will have an installed capacity of 1.2 million kilowatts, featuring four reversible pump-turbine generator units, each with a capacity of 300,000 kilowatts. The total investment is approximately 8.1 billion yuan (excluding transmission infrastructure). Classified as a Class I large-scale project, construction is expected to take 87 months. The project is being developed by Sichuan Energy Investment Mianzhu Pumped Storage Development Co., Ltd., with PowerChina Chengdu Engineering Corporation responsible for survey and design work during the preliminary and feasibility study phases.
As a key peak-shaving power source in Sichuan’s energy system, the Mianzhu Pumped Storage Power Station is expected to deliver significant economic, social, and environmental benefits. During construction, it is projected to contribute approximately 12 billion yuan to Sichuan’s GDP and create around 41,000 jobs. Once operational, it will generate an estimated 17.59 billion kilowatt-hours of electricity annually, with an expected utilization of 1,466 hours per year—providing power for approximately two million people. Additionally, the project is expected to generate about 95 million yuan in annual tax revenue.
By enhancing power grid stability, facilitating the integration of renewable energy, and supporting China’s transition to a greener, low-carbon energy system, the Mianzhu Pumped Storage Power Station will play a crucial role in ensuring the safe and reliable operation of the region’s electricity network.
