The Lianghekou hybrid pumped storage hydropower station marked two milestones on Sunday, completing excavation of its underground powerhouse and beginning concrete pouring for its downstream reservoir, bringing the mega clean‑energy project in Sichuan Province closer to completion.
Located on the Western Sichuan Plateau at an altitude of 3,000 meters, the facility uses the Lianghekou Reservoir, the province's largest, as its upper reservoir and the Yagen Level‑1 Hydropower Station reservoir as its lower reservoir. It is equipped with four reversible units of 300,000 kilowatts each, operating jointly with the 3 million kilowatts conventional units of the Lianghekou project to reach a total installed capacity of 4.2 million kilowatts.
Once completed, the plant will combine natural runoff power generation with bidirectional regulation through pumped storage.
The underground powerhouse, described as the project's "power heart," is buried about 500 meters beneath the mountain. Stretching nearly 200 meters in length and 60 meters in height, it reaches a maximum depth of 650 meters, serving as the core hub of the development.
This high-altitude green-energy "super power bank" is rapidly taking shape and is expected to play a vital role in strengthening clean-energy supply security and enhancing grid regulation capabilities in China.

Iranian Foreign Minister Seyyed Abbas Araghchi has described his visit to China as highly significant and productive, with the two sides holding in-depth talks on bilateral relations and all the pressing issues Iran currently faces.
Araghchi, who visited China on Wednesday and held talks with Chinese Foreign Minister Wang Yi, said in an interview with Iranian state-run IRIB news agency that post-war Iran is entering a new phase of international cooperation.
"Our Chinese friends also believe that Iran after the war is different from Iran before the war, that it has proven its capabilities and strength. Therefore, a new phase of cooperation between Iran and other countries lies ahead," he said.
The foreign minister said the two sides reviewed a full range of current issues and yielded fruitful results.
"We reviewed all the current issues, matters related to the war and how to end it, the negotiations currently under way, issues related to Iran's nuclear program and the peaceful nature of Iran's nuclear activities, matters related to sanctions, and all bilateral issues. The issue of the Strait of Hormuz, which was one of our serious topics, and the necessity of respecting the rights of the Islamic Republic of Iran, along with all existing viewpoints, were also discussed," he said.
