Argentina's government wants to attract large-scale data centers, but a regulation published September 25, Resolution 264/2026, now requires any new demand representing at least 0.5% of the Wholesale Electricity Market average, currently around 80MW, to secure its own generation and firm capacity covering 100% of maximum demand, rising to 115% for data centers. The country's roughly 15 large-scale data centers currently consume only 35MW to 40MW combined, according to SkyOnline COO Daniel Fiorda, compared with 280MW in Chile and 900MW in Brazil, meaning a single 80MW project would double the sector's existing demand. Argentina's grid operates at approximately 94% capacity during peak season, a figure Fiorda says leaves almost no buffer, and energy contracts can take a year or more to result in actual supply because renewable parks are built against already-sold capacity. Last-mile distribution reinforcement works in critical areas can take between one and three years, adding further delay for prospective data center developers.
Argentina's combination of near-maximum grid utilization, lengthy energy contract lead times, and a new self-supply requirement creates compounding barriers for large data center investment that set it well behind regional peers like Brazil and Chile. The regulation establishes a concrete capacity threshold, 80MW, at which developers must fully self-provision power, a precedent that could shape how other Latin American countries with strained grids handle surging data center demand.
Argentina is an emerging data center market in Latin America, and a BNamericas report on grid constraints limiting expansion is a newsworthy infrastructure story with regional significance distinct from already-published U.S. and European coverage.
