    The increasing occurrence of natural meteorological hazards, such as wildfires, cyclones, and floods, poses a significant risk to the continuity of electricity supply. Although these events are relatively rare, their effects can be extremely severe, highlighting the importance of assessing and mitigating their impact. In this context, it is essential to incorporate the concept of resilience into the power system to understand its ability to withstand, recover, and adapt in the face of high-impact, low-probability disruptive events. This work focuses on evaluating and strengthening the resilience of Ecuador’s transmission power system against wildfires. To achieve this, a multi-stage methodological framework is proposed to characterize wildfires, assess their impact on the components of electrical networks, and analyze the system’s response. Additionally, strategies are identified to mitigate the impact of these events and enhance the resilience of the transmission system. This work uses a novel model to characterize wildfires, considering physical and environmental parameters, as well as a specialized resilience model to calculate the probability of failure in overhead line conductors due to wildfires. Furthermore, a direct current optimal power flow model (DC-OPF) with losses, implemented in AMPL, is incorporated to evaluate the system’s response. The resilience metrics used include the energy not supplied (ENS), EIU, and the FLEP metrics derived from the conceptual resilience trapezoid curve. The proposed methodology is applied to a real case study, using data from Empresa Eléctrica Quito S.A., modeled in DIgSILENT Power Factory, and considering historical records of failures in electricity networks in the Metropolitan District of Quito due to wildfires. The results demonstrate that the assessment and implementation of enhancement strategies in transmission networks exposed to wildfires increase the resilience of the power system. In conclusion, the methodology developed in this work strengthens the power system’s ability to respond to wildfires and will contribute to the planning and development of more resilient electrical infrastructures in the Ecuadorian context.
