【AICC Original Article】Xuancheng Establishes China's First Pilot Zone for Joint Forest–Power Safety

After nearly a year of sustained efforts, as of January 10, the area of tree replacement along Xuancheng's major power transmission corridors reached 8,000 mu, exceeding the wildfire prevention targets. This marks the full completion of the nation's first multi‑dimensional coordinated wildfire prevention pilot zone for major transmission corridors and provides replicable, scalable technical and management experience for advancing "forest‑and‑power joint safety" nationwide.

Xuancheng is a key corridor for transmitting western and Anhui‑area power eastward. The city contains 24 ultra‑high‑voltage lines forming three major corridors — the largest scale and count in the province. More than 70% of these UHV lines traverse forested areas, making wildfire prevention a serious challenge. To minimize conflicts between power lines and tree lines and ensure the safe, stable operation of the power grid, in March 2025 the city was designated by the National Energy Administration as Anhui's sole pilot zone nationwide for multi‑dimensional coordinated forest and grassland fire prevention along major transmission corridors.

Since construction began, Xuancheng has strictly implemented local responsibilities and forged joint government‑enterprise efforts with coordinated action and community‑based prevention and control. The city established a normalized dynamic "zero‑hazards" mechanism for tree‑line, mapped three transmission corridors totaling 211 km of wildfire risk points, and carried out full vegetation clearance in 29 high‑risk segments while actively and orderly advancing tree replacement. In 48 relatively lower‑risk segments, firebreaks were constructed, and closed‑loop safety management of power facilities within fire prevention zones has been continuously advanced.

During construction, Xuancheng actively developed standards for wildfire‑prevention infrastructure under the "forest‑and‑power joint safety" initiative and built an emergency response model centered on localized reaction. Following a dual‑dimension "5×5" and "segment + time" prevention and control system, authorities dynamically update wildfire hazard levels and control standards for major transmission corridors, and completed fire prevention work during critical periods such as Qingming and the Winter Solstice. Three inspection stations were established in sensitive areas, 21 sets of portable "quick‑response" firefighting equipment were deployed, and "AI + video + dual‑spectrum" wildfire monitoring devices were installed to ensure fires are "detected fast, dispatched fast, and extinguished fast." Additionally, three differentiated typical remediation models were applied, a four‑level fire prevention and firefighting organization and a six‑level community defense chain were established, and a 30‑minute operations‑and‑maintenance response circle for transmission‑corridor wildfire hazards was created — achieving a shift from single‑track firefighting to systemic prevention and from passive response to proactive management, and comprehensively upgrading the wildfire prevention system for major transmission corridors.
