Fire Mitigation Strategies for Electrical Power Systems

This white paper provides a detailed examination of strategies and technologies aimed at minimizing the risk of wildfires caused by electrical power systems. It outlines the increasing threat posed by environmental factors such as climate change, high winds, and dry conditions, which, when combined with electrical arcs, elevate the risk of ignition. The document discusses various fire mitigation strategies employed by electric utilities, including preventive maintenance, strategic operational practices, enhanced system protection, and system hardening. Preventive maintenance involves regular inspections and vegetation management to reduce ignition risks. Strategic operational practices include assessing fire risks based on weather data, while enhanced system protection utilizes advanced technologies for rapid response to fire hazards. System hardening focuses on upgrading infrastructure to withstand environmental challenges. The paper concludes with a summary of distribution protection technologies available for fire mitigation, emphasizing the importance of a comprehensive approach to wildfire risk management in the electric utility sector.
