In March 2026, electricity tariffs in Buenos Aires will rise, significantly altering household billing structures. The new system under the Energy Subsidy Framework (SEF) will cut the subsidized consumption block for households from 300 kWh to 150 kWh per month. This change means that households will only receive discounts on the first 150 kWh consumed; any usage beyond this limit will be billed at full price without subsidies.

The Secretariat of Energy reported that approximately 63% of users are expected to see a reduction in their bills, largely due to lower consumption habits typical of the early-year months. However, for the remaining 37% of users, bills could increase substantially, with potential hikes ranging from $400 to $5,500, depending on user category and current consumption. This shift signifies a critical change in energy affordability and suggests a potential increase in financial pressure on higher-consuming households.

These developments in the energy subsidy policy underscore the Argentinian government's continued effort to manage energy distribution and costs amid an evolving economic landscape. The restructuring of subsidies is seen as part of broader energy reforms aimed at reducing fiscal burdens, although it raises concerns about equity and access to affordable energy for all residents of Buenos Aires.
