This surge in demand coincides with a profound transformation of the region’s energy mix. Historically, electricity generation relied heavily on large hydropower projects and fossil fueled thermal plants, with minimal wind and solar contributions. However, over the past decade, policy support and falling technology costs have driven a rapid expansion. Between 2015 and 2022, the region increased its renewable capacity by 51%.7 Today, wind farms sweep across Brazil’s northeast and Patagonia, while solar arrays dominate the Atacama Desert in Chile and spread across rooftops in Mexico.
Through the RELAC (Renewables in Latin American Countries) initiative, 16 countries have committed to achieving an 80% renewable electricity share by 2030.8 However, integrating such a high proportion of variable renewables presents operational and investment challenges, similar to those faced globally. This includes the need for quick establishment of backup sources such as gas and energy storage, greater regional grid interconnection to balance transmission needs, and smart grid technology to manage increasingly complex power flows. Significant upgrades to transmission and storage capacity will be essential to sustain momentum without compromising reliability. In short, Latin America is on the cusp of both rapid demand growth and deep decarbonization, a combination that could make it one of the most dynamic electricity markets in the world this decade, provided its infrastructure keeps pace.
Infrastructure gaps and solutions
Despite Latin America’s broad progress in energy generation, significant infrastructure gaps remain in transmission, distribution, and storage. In many countries, generation capacity has outpaced the transmission equipment needed to deliver that energy reliably to consumers. The result is a classic bottleneck dynamic, with consumers facing severe delays or curtailment due to an insufficiently developed grid.
There are numerous examples of this dynamic in action within Latin America. Chile serves as a cautionary tale in the power sector. Blessed with vast solar and wind capacity, the country has built so many renewable plants that it routinely produces more power than its grid can absorb at midday. This results in notable curtailment, or clean energy going to waste due to insufficient transmission infrastructure. In 2024, Chile curtailed approximately 5.9 terawatt-hours of renewable electricity, a 121% increase from the prior year.9 Inadequate grid investment remains a persistent challenge, not only in accommodating future wind and solar capacity but also in maximizing output from existing plants. Argentina provides another example, where large volumes of shale gas were stranded in Patagonia for years due to inefficient pipelines. The first phase of the Néstor Kirchner Gas Pipeline in 2023 significantly enhanced transport capacity from Vaca Muerta, helping to alleviate the nation’s energy trade deficit. Consequently, the country’s full-year energy trade surplus surged to $5.6 billion in 2024, buoyed by pipeline expansion and upstream activity.10
One of the primary reasons for these infrastructure gaps is the ownership structure of the power sector. While generation has seen considerable private investment, transmission and distribution remain largely dominated by state monopolies. Over the years, many Latin American countries have liberalized and attracted private capital into power generation. Independent power producers now contribute significantly to markets in nations like Brazil, Chile, and Peru. By contrast, transmission and distribution utilities have frequently remained under government control or have been less open to private participation. As a result, the wires side of the business has not kept pace.
A review by the Inter-American Development Bank found that most Latin American nations adopt a mix of public and private ownership for generation, but transmission and distribution tend to be predominantly public and often monopolistic. For example, the Mexican government’s Federal Electricity Commission (CFE) owns the transmission and distribution grid, and recent policy shifts have curtailed some private generation opportunities in favor of the state utility. Even in countries more open to private investment, transmission expansion can be slow due to lengthy permitting processes, right-of-way issues, and limited budgets of state utilities, causing delays in building new lines. The result is that renewable projects in remote areas can be ready to generate power, but the grid to transport that power lags - a scenario seen in southern Brazil and northern Chile, among others.
