During the construction process, the builders of Gezhouba created the largest construction production record in the industry with the largest daily footage of 3.89 meters and monthly footage of 108 meters in a single cycle. After all units are put into operation, the average annual power generation is about 2.43 billion kWh, which can deliver a steady stream of clean energy to thousands of households.
