Energy exports to the regional market halved in value year-on-year, totaling about $66.5 million USD. These exports were minimal during the first five months but rebounded in the second half of 2025, predominantly to Argentina. Concurrently, UTE resumed energy imports, primarily from Argentina and to a lesser extent Brazil, accounting for nearly 5% of total electricity demand. This strategy aimed to replace costlier local thermal generation. Hydroelectric power’s share in the generation mix decreased from near 50% to 46%, while thermal generation was utilized to meet peak demand periods, representing 1.9% of output.
Operating costs rose 5.9% to $46.37 billion pesos, with a notable 60% increase in costs related to energy materials and lubricants. Social electricity subsidies grew by approximately $136 million USD, benefiting about 188,000 vulnerable households with 80-90% discounts. UTE’s total liabilities included short-term debt of $34 billion pesos and long-term obligations of $105.7 billion. The company transferred $159 million to the central government in 2025, with an additional $25.6 million scheduled for payment in 2026, reinforcing its role as a key fiscal contributor.
