A case submitted by State Grid Quzhou Power Supply Company and State Grid Jiangshan Power Supply Company was selected as a featured case in The Series of Reports on Biodiversity Conservation by Chinese Enterprises from the 17th Conference of the Parties to the UN Convention on Biological Diversity (COP17), which concluded on Oct 31 in Yerevan, Armenia.

Quzhou's mountainous terrain has long created safety conflicts between trees and power lines, and traditional clearance methods can cause soil erosion and damage wildlife habitats. Since 2025, State Grid Jiangshan has partnered with forestry authorities, agricultural investment groups, and local farmers to build "power-benefiting agriculture economic corridors."

This model replaces tall native trees that threaten line safety with low-growing oil tea shrubs, eliminating risks such as trees touching conductors or falling during severe weather, while delivering the ecological benefits of mature oil tea forests, helping conserve water, stabilize soil, and provide friendlier habitats for local wildlife.

To date, Jiangshan has piloted four such corridors, planting 1,380 oil tea shrubs across 17.52 mu (1.17 hectares).
