Towards a 100% Renewable Uruguay: Challenges and Opportunities in the Energy Transition

Uruguay is on path toward a 100% renewable energy system, achieving 91% 
renewable electricity generation in 2022. This report analyzes the challenges and 
opportunities of this transition in the face of growing energy demand and the challenges 
posed by climate variability. Through the OSeMOSYS model, three scenarios were 
evaluated: Tendential (TR), Water Scarcity Scenario (WS), and  Water Scarcity + 
Grid-Connected Batteries (WS+GCB), focusing on the evolution of the energy matrix 
and the resilience of the system in response to reduced water resources.
