AI Data Centers & Digital Infrastructure in South America
South America’s data-center market is developing through five different infrastructure models. Brazil combines operating scale with a very large grid-access pipeline, Argentina is testing whether energy resources can support hyperscale projects, Chile pairs cloud demand with increasingly visible grid and water constraints, Uruguay has moved a major Google project into construction, and Paraguay is trying to convert hydro-powered digital infrastructure into dedicated AI and HPC capacity.
AI data centers in South America are increasingly an energy, grid, cooling, fiber and financing market.
Brazil has the largest current operating ecosystem among the five markets compared here, but its 38 GW of grid-access requests are far larger than installed capacity and should not be read as a construction pipeline. Argentina has attracted multiple large proposals in Patagonia and Neuquén, while most remain pre-construction. Chile combines an established data-center market with increasingly visible transmission and water constraints. Uruguay has Google’s US$850 million Canelones data center under construction. Paraguay already hosts large hydro-powered digital loads, but dedicated AI and HPC capacity is still developing.
The September 2026 Econosur analysis Why AI’s Cost Problem Could Reshape Data Center Investment in South America compares these five markets through project maturity, power, grids, cooling, fiber, regulation and financing.
New evidence since the previous August update materially changes the regional picture. Reuters reported additional early-stage Patagonia projects and Pampa Energía’s evaluation of up to 500 MW near Loma de la Lata. Brazil’s REDATA bill has passed Congress and remains in the presidential sanction period. Chile’s energy regulator has warned that power-system expansion is not keeping pace with data-center demand. Google’s Canelones project is under construction in Uruguay, while Paraguay’s Taiwan-backed 10 MW sovereign AI project remains in technical feasibility study and HIVE is building a separate AI/HPC route at Yguazú.
Data Centers in South America: One Region, Different Infrastructure Models
The phrase “South America data centers” hides several distinct market models. Countries differ in current installed capacity, electricity systems, fiber connectivity, cloud demand, regulation and the maturity of operators and enterprise customers.
This matters because data-center investment pulls in substations, transmission, cooling, fiber, construction, security, monitoring, software, cloud partnerships and long-term energy contracts. The economics of AI strengthen that connection: lower unit costs can support much greater compute use, while the physical system behind that use becomes more capital- and power-intensive.
The new five-country AI cost and data-center investment analysis therefore extends the earlier energy-to-compute framework beyond Argentina and Paraguay to Brazil, Chile and Uruguay.
The regional digital-infrastructure stack has three layers: physical infrastructure, operating capability and digital demand. Weakness in any one layer can prevent announced capacity from becoming a viable compute market.
Argentina and Paraguay: Energy Advantage, Different Evidence States
Argentina and Paraguay remain useful comparison cases because both have strong energy propositions, but the evidence behind their headline megawatts is different.
CABASE’s May 2026 infrastructure map identified 13 operating data centers in Argentina with about 32 MW of installed power capacity. That small existing base sits beside much larger proposals. OpenAI and Sur Energy signed a letter of intent in October 2025 to explore Stargate Argentina at up to 500 MW and up to US$25 billion at full scale. The Argentine government reported in May 2026 that the project had not submitted a RIGI application at that reporting date.
The pipeline has broadened since the previous version of this page. Reuters reported on September 7 that Pampa Energía is evaluating a data center near its Loma de la Lata power plant in Neuquén with potential consumption of up to 500 MW. Interested investors are first considering a 20–40 MW pilot, while electrical infrastructure for the full scale could cost almost US$900 million. Reuters also identified a 120 MW FlexDomes proposal in Neuquén, a 300 MW first stage proposed by Green Capital in Chubut and a 30 MW first stage linked to an IT park in Bahía Blanca. Most remain early-stage and still depend on financing, formal agreements and infrastructure delivery.
Argentina’s regulatory perimeter has also changed. Decreto 105/2026 explicitly includes artificial intelligence within the RIGI technology sector. That creates a potential incentive route for qualifying projects, but it does not convert an announcement into an approved RIGI project.
Paraguay starts from a different physical base. HIVE Digital Technologies has large operating hydro-powered infrastructure associated mainly with Bitcoin mining. Its separate AI/HPC pathway is now more defined: the company says civil works are complete for a new 100 MW substation at Yguazú, with energization expected in September 2026, construction of a new Tier III data center expected later in 2026 and a ready-for-service target in the second half of 2027.
The Paraguay–Taiwan sovereign AI project remains earlier. MITIC says the first phase would target 10 MW and estimates US$300–500 million of investment, but the ministry still described the project as being in technical feasibility study on August 25, 2026.
Headline megawatts are not interchangeable. Argentina’s Stargate figure is a proposal, Pampa’s 500 MW is an evaluated maximum with a smaller pilot under discussion, HIVE’s existing Paraguay infrastructure is mainly Bitcoin-focused, and the Taiwan-backed 10 MW project is still at feasibility stage. The relevant comparison is operating, contracted, permitted, financed, under construction and announced capacity.
See the Argentina–Paraguay energy-to-compute analysis for the original two-country framework. The broader regional comparison now also includes Brazil, Chile and Uruguay.
Brazil: Operating Scale, Policy and Grid Pressure
Brazil is structurally different because it already combines a large digital economy with enterprise cloud demand, platform scale, financial services, telecom infrastructure and a substantial operating data-center base. In June 2026, the Ministry of Mines and Energy said Brazil had 205 data centers in operation.
The requested power pipeline is much larger than the operating base. The ministry cited 38 GW of grid-access requests for data-center projects and said requests had grown 330% between 2024 and 2025. These are connection requests, not 38 GW of committed construction. EPE is already treating the demand as a transmission-planning issue and in June proposed a scalable solution for up to 4 GW of electro-intensive loads in Ceará and Piauí from 2032.
REDATA now adds a national policy layer. Brazil’s Senate approved PL 278/2026 on September 1 and transmitted it for presidential sanction on September 4. As of September 10, the sanction-or-veto period remains open through September 25. The bill links tax incentives to conditions including domestic processing capacity, water efficiency and electricity from renewable or low-emission sources.
The Econosur REDATA analysis examines those conditions in detail. Brazil’s current challenge is no longer simply attracting announced demand; it is coordinating fiscal policy, grid expansion and project delivery at a scale that the existing power system can support.
See the Brazil market profile for the wider industrial and infrastructure context.
Uruguay: Construction, Telecom Infrastructure and Cooling Design
Uruguay shows how a smaller domestic market can gain digital-infrastructure credibility through projects that have moved beyond announcement.
Google’s Canelones data center is the clearest example. Google announced more than US$850 million of investment in 2024, and Uruguay XXI currently states that construction is underway at Parque de las Ciencias. The project’s environmental record identifies air cooling rather than water-based server cooling, making cooling design part of the site’s infrastructure logic.
Antel adds a second layer. In February 2026, Antel and Google Cloud announced that Google Distributed Cloud infrastructure would be hosted at Antel’s Pando data center. The Uruguayan government subsequently announced a separate US$70 million Antel data center specialized in AI in Canelones.
Uruguay’s proposition therefore combines renewable electricity, telecom infrastructure, cloud deployment, environmental design and institutional execution. The Uruguay digital analysis provides the wider national context and complements the five-country comparison with a deeper national view.
Chile: Operating Scale, Grid Constraints and Cloud Expansion
Chile combines an established data-center market with a strong enterprise and cloud-demand base. Published capacity figures, however, use different market definitions. InvestChile cited a JLL dataset showing 166 MW operating in April 2026, while Cushman & Wakefield reported 279 MW of operational capacity in Santiago for the second half of 2025. The figures should not be silently combined because their geographic scope and provider methodology differ.
The more important current signal is grid delivery. On May 12, Chile’s National Energy Commission warned that expansion of electricity infrastructure was not advancing at the same pace as data-center demand. The regulator highlighted transmission constraints, storage, interruptible loads and the need for better medium-term planning.
AWS continues to list its South America (Chile) Region as coming in 2026 with three Availability Zones and says it plans to invest more than US$4 billion in Chile over 15 years. The Region should still be treated as planned rather than operational until launch.
Water and cooling also affect site viability. The Cerrillos Data Center case required renewed environmental scrutiny over groundwater impacts, while the developer had proposed moving from water-based cooling towers to air-cooled chillers. Chile therefore illustrates why renewable generation alone does not determine data-center competitiveness.
Econosur’s Chile power-grid analysis provides the electricity-system context. The Chile SaaS analysis and Fintoc company analysis add the enterprise and transaction-demand layer.
“The usable megawatt is the one that can be connected, cooled, financed and matched with real compute demand.”

The Physical Infrastructure Stack Behind AI Data Centers
Data centers are infrastructure assets. Their viability depends on much more than headline megawatts.
- Power: grid access, substations, transmission, backup systems and long-term electricity contracts.
- Fiber: backbone capacity, international routes, redundancy, latency and submarine-cable connectivity.
- Cooling: thermal design, water strategy, climate conditions and energy efficiency.
- Sites: land, construction capacity, permitting, physical security and access to equipment.
- Operations: uptime, maintenance, cybersecurity, technical staff and specialized service providers.
This is why the Energy & Infrastructure analysis is directly relevant. Data centers are becoming another large industrial load competing for power-system capacity.
The Digital Demand Stack: Cloud, SaaS, Payments and Platforms
Infrastructure requires customers. Data-center development is stronger when it sits near enterprise cloud use, financial services, platforms, government systems and digitally intensive companies.
Mercado Libre is the clearest Econosur company case for this demand side. In Q2 2026, the company reported US$21.9 billion in GMV, about US$101 billion in total payment volume and 88 million fintech monthly active users. The figures show why digital infrastructure is not only a supply story: large regional platforms create sustained demand for cloud, connectivity, transaction processing, security and data systems.
Together with Fintoc and Chile SaaS, these cases connect physical compute capacity with real transaction and enterprise demand.
What Companies Need to Read Correctly
A South American data-center or digital-infrastructure strategy should identify which layer of the stack creates the opportunity and which layer creates the bottleneck.
- Energy layer: Is reliable power available at the required scale and contract structure?
- Connectivity layer: Does fiber redundancy support the required latency and uptime?
- Site layer: Can cooling, land, construction and permitting support the project?
- Operator layer: Are technical partners, maintenance and specialized staff available?
- Demand layer: Which cloud, AI, enterprise, fintech, platform or public-sector customers justify capacity?
The biggest analytical mistake in this market is to compare headline megawatts as if they represented the same evidence state. Argentina’s 500 MW Stargate figure is still a proposal. Pampa Energía is evaluating up to 500 MW near Loma de la Lata, but investors are first considering a 20–40 MW pilot. Brazil’s 38 GW refers to grid-access requests, not built capacity. Chile’s published operating-capacity estimates differ by dataset and scope. Google’s US$850 million Uruguay project is under construction. Paraguay’s Taiwan-backed 10 MW AI center remains at technical-feasibility stage. A useful comparison therefore starts with project status before comparing scale.
Cross-Market Assessment
The regional comparison works best when project maturity comes first. Operating capacity, construction, signed power agreements, connection requests, feasibility studies and letters of intent are separate evidence states. Only after that distinction is clear does it make sense to compare power cost, grid access, cooling, fiber, operator depth and customer demand.
The five-country AI cost and data-center investment analysis is now the broadest regional comparison. The Argentina–Paraguay analysis provides the original energy-to-compute framework, REDATA adds Brazil’s policy structure, Chile’s power-grid analysis explains transmission constraints, and Uruguay’s digital analysis connects telecom, cloud and institutional execution.
The main figures on this page are tied to the status of the underlying projects. Operating capacity, grid-access requests, company expansion plans and letters of intent are kept separate rather than added together as one regional pipeline.

Explore custom market analysisFrequently Asked Questions
Which countries matter most for data centers in South America?
Brazil has the largest current operating ecosystem among the five markets compared here and 38 GW of grid-access requests, although those requests are not built capacity. Chile has a substantial operating market but published capacity totals differ by dataset, and its energy regulator is warning about grid-delivery constraints. Argentina has several large early-stage proposals but a much smaller current operating base. Uruguay has Google’s US$850 million Canelones data center under construction. Paraguay already hosts large hydro-powered digital loads, while dedicated AI/HPC projects remain in development or feasibility.
Is cheap electricity enough to build a data-center market?
No. Competitive electricity is only one layer. Data centers also require grid access, substations, fiber redundancy, cooling, water strategy, operators, hardware access, long-term contracts, permitting and paying demand.
Why is Antel relevant to South American digital infrastructure?
Antel is Uruguay’s state telecom and digital-infrastructure company. Its fiber, mobile networks, international connectivity, data infrastructure and public ownership make it a useful company-level case of state capacity supporting a digital market.
What does Fintoc show about digital infrastructure beyond data centers?
Fintoc shows the transaction layer of digital infrastructure. Its platform combines payments, recurring collections, reconciliation and APIs, while Fintoc Pagos S.A. now operates as a CMF-authorized non-bank payment-card issuer with provision of funds. That connects software infrastructure directly with regulated financial rails.
Why does Mercado Libre matter to digital infrastructure?
Mercado Libre represents the demand side of the regional digital stack. Marketplace activity, payments, credit, logistics and seller data create large-scale demand for cloud, connectivity, payment and data infrastructure.
Which Econosur analyses provide the main digital-infrastructure context?
The main current pages are the five-country AI cost and data-center investment comparison, the Argentina–Paraguay energy-to-compute analysis, Brazil REDATA, Chile power-grid infrastructure, Uruguay’s Digital Bet, Paraguay power-grid regulation and the Antel company analysis.
