The electricity generation report of the Latin American and Caribbean Energy Organization (OLACDE) highlights a total generation of 161 TWh in August 2025, a volume similar to that recorded in July. The report underscores relative variations in the regional energy mix and emphasizes the dynamics of renewable and non-renewable energy sources.
In August 2025, the generation mix continued to be dominated by hydropower, with a 43.6% share. However, a 4% decline in hydropower generation compared to July 2025 was observed, attributed to drought conditions in the Andean region and Central America.
To offset this decline, fossil-based sources increased their contribution, with natural gas raising its share to 26.1% of the total. This increase reflects the role of natural gas as a firm energy source, essential to ensuring the security and stability of electricity supply in the region. This trend was further reinforced by the commissioning of new energy complexes, such as Energía del Pacífico (EDP) in El Salvador.
Within the segment of other renewables, solar energy recorded a 5% month-on-month growth, driven by the entry into operation of new photovoltaic installations. Wind generation also showed a slight increase, attributed to the persistence of strong winds in Southern Cone countries.
On a year-on-year basis (August 2024 vs. August 2025), total electricity generation in Latin America and the Caribbean increased by 3.9%. Hydropower emerged as the resource with the largest absolute growth over this period, with an increase of 9.4 TWh.
Despite the predominance of renewables (101 TWh), the regional Renewability Index declined to 63% in August 2025, down from 65% in July, marking one of the lowest levels in the past five months. This decrease is mainly explained by the reliance on hydropower generation and the increased contribution of non-renewable sources, which totaled 60 TWh.
