The COVID-19 pandemic has highlighted critical vulnerabilities in global power systems, particularly in regions like Mindanao, Philippines. This study aims to develop a comprehensive resiliency model for renewable energy (RE) systems by leveraging existing power system metrics in Mindanao. The model is structured into four profiles: energy balance, energy mix, cost, and reliability, each representing various aspects of the power system's performance before and during the pandemic. The findings reveal that the energy balance and energy mix profiles experienced slight impacts due to reduced demand and pre-pandemic planning, achieving resiliency scores of 16.33/18 and 13.5/18, respectively. The cost profile remained unaffected with a perfect resiliency score of 6/6, attributed to pre-pandemic power purchase agreements, while the reliability profile showed minimal disruption with a score of 4.67/6. Overall, the study achieved an aggregate resiliency score of 40.5/48, indicating that the Mindanao power system maintained stable operations during the pandemic. The research successfully incorporated RE performance into the resiliency model, though it acknowledges the model's limitations and suggests the inclusion of additional metrics for further refinement. This study contributes valuable insights into enhancing power system resilience, particularly in developing regions, amid unprecedented global challenges.
