The job has raised concerns about serious safety risks and prompted Chinese media to demand a transparent answer.
Vinh An pumped-storage hydropower plant in Fujian province is a key project in the pumped-storage development plan for the period 2021-2025, playing a role in ensuring regional power security and supporting China's green energy transition.
Accusations of violations began to stir up public opinion after Economic Information Daily under Tan Hoa Xa published an investigation on November 27, accusing the use of poor quality materials and the construction of cranes at the project.
The investigation shows that low reservoirs - a key item determining the plant's power generation capacity - have "serious quality defects", along with many other problems that experts warn could threaten the overall safety of the dam.
In a statement released on November 29, Power China Construction Corporation affirmed that it granted great importance to the incident. This is one of the largest construction - technical corporations in the world and is the parent company of contractors implementing the project.
PowerChina said it has established a separate investigation team on the project's quality issues. We will coordinate with relevant parties to conduct a comprehensive investigation and handle it in accordance with the provisions of law, the statement said.
According to another article published in the Economic Information Daily on November 30, the National Energy Administration (NEA) sent staff to the site on November 28 as part of a joint investigation with local authorities.
The project started construction of the low-lying reservoir in December last year. The pumped-storage hydropower plant works by pumping water from low-lying reservoirs to high-lying reservoirs during peak hours and releasing them to generate electricity during peak hours, helping to stabilize the local power system.
