Abstract

This paper presents a modular Transportable Battery Energy Storage System (TBESS) designed to support essential infrastructure during climate-induced disasters that frequently occur in southern Brazil. The system integrates firstand second-life lithium-ion batteries coordinated by an intelligent Energy Management System (EMS).Technical feasibility and environmental performance were evaluated through simulations using real demand profiles from emergency facilities in Brazil. The TBESS provided up to nine hours of energy autonomy without diesel backup, with its performance validated through real demand-based simulations. When extended operation with diesel generation is required, greenhouse gas emissions remain significantly lower than in diesel-only configurations. The battery system alone can supply 44% of the demand for 24 hours, and still provide 15% after 72 hours. This solution addresses immediate disaster-response needs while contributing to Brazil’s broader energy transition. The proposed TBESS enhances both the resilience and sustainability of emergency energy supply systems.
