Creating biomass firebreaks for safe forest and power line coexistance

State Grid Jinhua Power Supply Company has introduced biomass firebreak forest belts to enhance ecological and power line safety. Collaborating with local departments, they established a management plan for power line corridors, creating a 1-kilometer firebreak along a 10-kV line with fire-resistant shrubs. This approach improves power line safety in mountainous areas without reducing forest coverage, addressing long-standing issues such as tree-line conflicts and forest fire risks at their source.

Since the beginning of the year, under the guidance of local authorities, the company has continued to refine its “government–enterprise joint inspection” mechanism. Over 300 tree obstructions have been cleared to prevent potential electrical hazards and fire spread. The company has implemented a graded responsibility system, combining local management with principal accountability, and developed a detailed risk ledger down to specific lines and responsible personnel. Ahead of the October–November peak forest fire season, State Grid Jinhua Power Supply Company has carried out a comprehensive re-inspection of key lines running through forested areas, conducting tree clearing and equipment maintenance simultaneously.

To ensure long-term prevention, the company has also established a provincial–municipal–county information-sharing platform, integrating drone patrol and fire-risk warning data, and regularly organizing joint emergency drills to strengthen coordination efficiency and improve forest–power co-safety governance.

Going forward, the company plans to summarize and replicate the experience gained from this initiative, further advancing a new model of safe and sustainable coexistence between power grid infrastructure and the ecological environment.
