The article discusses significant energy sector developments in Latin America, focusing on Argentina, Brazil, and Chile from September and October 2024. In Argentina, CAMMESA launched a new MATER call to award up to 880 MW in transmission capacity, with priority dispatch for 209 MW and capacity distribution based on technology and location. Brazil has reinforced its energy transition commitment by promoting solar, wind, biomass, green hydrogen, and nuclear energy initiatives. Key achievements include surpassing 30 GW of installed solar energy capacity, partnering for green hydrogen production, passing a Low Carbon Energy Law, boosting biomass electricity generation, launching an offshore wind tender, and reducing carbon emissions. Additionally, Chile modified its Public Transportation Subsidy Law to accelerate electric truck adoption, enhance regional funding and partnerships, and expand the electric fleet. The country also extended electricity subsidies to 4.7 million users, with reductions in FET charges, PMGD compensations, tax credits for SMEs, and deferral/exemptions for PMGD projects. These developments signal a positive shift towards cleaner and more sustainable energy sources in the region.
