The construction of pumped storage power stations will further promote the green and sustainable development of the energy industry. According to incomplete statistics from Seetao.com, in December 2022, a total of 36 pumped storage power stations with a total installed capacity of 49,960MW will start pre-feasibility study review, approval, start of construction, and commissioning.

The most noteworthy thing is that on December 29, 2022, the construction of the hybrid pumped storage project at the two estuaries of the Yalong River in Ganzi Tibetan Autonomous Prefecture, Sichuan Province officially started construction. The Lianghekou mixed storage project is the first pumped storage project in Sichuan Province and will become the largest hybrid pumped storage project in the world after completion. The site is 3,000 meters above sea level, relying on the largest reservoir in Sichuan Province——Lianghekou Hydropower Station Reservoir as the upper reservoir, and Yagen Class I Hydropower Station connected downstream as the lower reservoir.

Accelerated start of multi-regional projects

On the whole, four power stations, Huangyang Pumped Storage Power Station in Gansu Province, Fuping Pumped Storage Power Station in Hebei Province, Nanzhang Pumped Storage Power Station in Hubei Province, and Qianxi Pumped Storage Power Station in Hebei Province, have been approved by the National Development and Reform Commission.

Henan Songxian Pumped Storage Power Station, Yalong River Estuary Hybrid Pumped Storage Power Station, Hebei Xingtai Pumped Storage Power Station, Hubei Pankou Pumped Storage Power Station, Hebei Lingshou Pumped Storage Power Station, Hebei Luanping Pumped Storage Power Station , Zhejiang Pan'an Pumped Storage Power Station started construction of 7 pumped storage power stations.

Gansu Hetuo Pumped Storage Power Station, Qinghai Hainanzhou Gonghe Pumped Storage Power Station, Jilin Ji'an Pumped Storage Power Station, Hebei Zhangjiakou Shihu Reservoir Pumped Storage Power Station, Anhui Tongcheng Pumped Storage Power Station 5 new contracts.

Shanxi Qinshui Pumped Storage Power Station, Guangdong Huangmaogang Pumped Storage Power Station, Liaoning Taizihe Pumped Storage Power Station, Hunan Liling Pumped Storage Power Station, Liaoning Yingkou Yushi Pumped Storage Power Station, Liaoning Province Yanshan Lake Pumped Storage Power Station, Sichuan Jiangyou Pumped Storage Power Station, Hubei Huanglongtan Pumped Storage Power Station, Hubei Songzi Pumped Storage Power Station, and Zhejiang Kecheng Pumped Storage Power Station started or passed the pre-feasibility study review.

Looking at the provinces across the country, Hebei will have the most updates on pumped storage power stations in December 2022, with a total of 6 pumped storage projects with a capacity of 9,000MW.

From the point of view of the construction unit, in addition to State Grid Xinyuan, Three Gorges Energy and other units, China Machinery Industry Engineering Corporation signed an investment cooperation project for the Minxian Hetuo Pumped Storage Power Station Project with Minxian County, Dingxi City, Gansu Province on December 27, 2022 protocol. SINOMACH developed and invested in the construction of a pumped storage power station with an installed capacity of 1,200MW in Yirengou, Hetuo Town, Minxian County, Gansu Province, with an estimated investment scale of about 8 billion yuan. After the completion of the project, it is of great significance to improve the new energy consumption capacity and peak shaving capacity of Gansu Province, and to ensure the safe operation of the power system.
