Huangdeng Hydropower Station in Lanping County, Nujiang

Huangdeng Hydropower Station is located in Lantsang Bai and Pumi Autonomous County, Nujiang Prefecture, Yunnan Province. It is a key project during China’s 12th Five-Year Plan and a backbone project for the “West-to-East Power Transmission” initiative. Below is a detailed introduction to Huangdeng Hydropower Station:

Basic Information

  • Location: Within Lantsang Bai and Pumi Autonomous County, Nujiang Prefecture, Yunnan Province.
  • Installed Capacity: 1.9 million kilowatts.
  • Annual Power Generation: An average annual power generation of 8.57 billion kilowatt-hours.
  • Dam Height: 203 meters, making it the world’s highest roller-compacted concrete gravity dam.

Technological Innovations

  • Digital and Intelligent Construction: Pioneered a new model of fully digitalized and intelligent construction for extra-high roller-compacted concrete gravity dams, achieving a leap from digital to intelligent construction, leading the development of dam construction technology, and filling a domestic technological gap.
  • Smart Temperature Control: First in China to achieve full-process smart temperature control in concrete dam construction, with two achievements incorporated into national energy industry standards.
  • Fish Lift Project: Constructed the world’s highest fish lift project (152 meters in height) with independent intellectual property rights, becoming China’s first high-dam fish passage system with independent intellectual property rights.

Honors and Achievements

  • National Quality Engineering Gold Award: On January 7, 2023, Huangdeng Hydropower Station was awarded the National Quality Engineering Gold Award.
  • International Milestone Award: In late 2019, Huangdeng Hydropower Station received the fourth Roller-Compacted Concrete Dam International Milestone Award.
  • Technological Achievements: Applied seven key national energy-saving and low-carbon technologies, ten major items (31 sub-items) of the top ten new technologies in construction, 37 new technologies in electric power construction, and 21 self-innovated technologies.

Environmental Protection

  • Fish Breeding and Release Station: Built the largest fish breeding and release station in the Lancang River Basin.
  • Ecological Benefits: Since its commissioning, it has achieved 1,648 days of safe production, generated over 39 billion kilowatt-hours of electricity, and reduced carbon dioxide emissions by 25 million tons, making a positive contribution to achieving China’s “dual carbon” goals.
