Arcplus Group PLC and the Impact of China’s New Hydropower Project

China has embarked on an ambitious new project, the world’s largest hydropower dam, located on the eastern rim of the Tibetan Plateau. Premier Li Qiang announced the commencement of construction, with an estimated cost of at least $170 billion. This project, which includes five cascade hydropower stations, is expected to produce 300 billion kilowatt-hours of electricity annually, equivalent to Britain’s annual consumption. The dam, situated in the lower reaches of the Yarlung Zangbo, leverages a section of the river that drops 2,000 meters over 50 kilometers, offering significant hydropower potential.

The announcement has been positively received by Chinese markets, seen as a strong economic stimulus, leading to a rise in stock prices and bond yields. However, concerns have been raised by India and Bangladesh regarding the potential impact on downstream populations, and NGOs have highlighted environmental risks to the plateau’s diverse ecosystem. Beijing has assured that the dam will meet power demands in Tibet and across China without significantly affecting downstream water supplies or the environment, with operations expected to begin in the 2030s.

Market Reactions and Sector Impacts

The construction of the hydropower project has had a notable impact on various sectors within the Chinese market. On July 21, 2025, the A-share market saw significant gains across traditional sectors, including construction materials, engineering machinery, and construction. Companies such as Jinyu Group, Qingsong Building Materials, and Fuzhou Cement experienced substantial increases, with several stocks hitting their daily price limits.

The construction and engineering sector, in particular, saw a surge, with China Construction (601669) leading in trading volume, reaching a turnover of approximately 39.68 billion yuan. This positive momentum contributed to the overall rise in the A-share market, with the Shanghai Composite Index closing 0.72% higher, marking a new high for the year.
