China’s Zoige grasslands power project protects birds and the grid

On Sichuan’s Zoige grasslands, State Grid Sichuan Electric Power has turned power towers into safer nesting sites for raptors while cutting bird-caused outages. The effort, launched in 2022, shows how grid operations and wetland protection can work together on the Qinghai-Tibet Plateau.

Why it matters: - Zoige is a critical “Water Tower” for the Yellow River basin and China’s largest alpine peat wetland. - About 30% of the Yellow River’s upstream water originates in Zoige, so ecological damage there has regional consequences. - The project reduces bird-related power failures while protecting nationally protected raptor species and supporting grassland balance.

What happened: - In 2022, State Grid Sichuan Electric Power launched the “Life Nest” public-benefit initiative on the Zoige grasslands of Sichuan Province. - The company worked with ornithologists and forestry and grassland authorities to survey 12,000 kilometers of power lines and more than 30,000 towers. - The team mapped bird activity, identified key nesting areas and combined guidance with deterrence to manage the conflict between birds and transmission equipment.

The details: - Before 2021, bird activity caused about 15 line trips a year in Zoige. - The grasslands have few tall trees, so power transmission towers became nesting sites for raptors such as saker falcons and upland buzzards. - Bird droppings contaminated insulators, and nesting material such as wire and grass stems caused short circuits and outages. - Artificial nests were installed in safe tower locations using corrosion-resistant golden vines and insulated wire. - The latest 3.0 nest design is 1 meter in diameter and 30 centimeters deep, with a shape that closely imitates a natural nest. - Dynamic rotating devices with mirror reflections were added to tower crossarms to discourage birds from dangerous areas. - Live parts were insulated as an added safety measure. - In the Zoige pilot area, 67 artificial nests and 178 dynamic rotating devices have been installed. - The project has attracted more than 200 birds. - Saker falcons, upland buzzards and other nationally protected species have laid 58 eggs, and the hatching rate reached 100%. - Raptors help control plateau pikas, which contribute to grassland degradation. - One raptor family can prey on 600 to 700 pikas in a single breeding season.

Between the lines: - The project shows a shift from simply driving birds away to designing infrastructure that accommodates wildlife behavior. - The approach combines field ecology, physical design and digital monitoring, which makes the model easier to adapt to other high-altitude grid areas. - The presence of raptors also creates an ecological benefit beyond power protection by helping reduce rodent pressure on grasslands. - The work bridges local knowledge and newer technology, from ground surveys to drone patrols and AI-adaptive inspection.

What’s next: - The “Snowland Eagle” high-altitude women’s drone patrol team now monitors nests with drones and AI-adaptive inspection technology. - Five Tibetan women born after 2000 are carrying out inspections that once took four days manually and now take about three hours. - The project’s repeatable method — scientific monitoring, artificial nesting, physical deterrence and digital inspection — is positioned as a model for high-altitude power grid ecological management. - The initiative has won more than 10 national, provincial and industry innovation awards.

The bottom line: - Zoige’s “Life Nest” project shows that grid reliability and wildlife protection do not have to conflict on the Qinghai-Tibet Plateau. - The towers now support both electricity delivery and a healthier grassland ecosystem.
