Chile Targets Six Gigawatts of Battery Storage Following Landmark Energy Laws
Santiago, Monday, 31 August 2026.
Driven by 2024 legislative incentives for hybrid solar installations, Chile’s battery storage capacity is set to surpass six gigawatts by late 2026, leading Latin America’s clean energy transition.
Legislative Catalyst
Chile is projected to surpass 6 GW of battery energy storage systems (BESS) capacity by the end of 2026, driven by a landmark 2024 law that incentivized hybrid solar and storage installations [1]. This legislative move quickly led to a flood of big battery project announcements, as the capacity payments model combined with arbitrage revenue means hybrid solar and storage is very profitable [1]. The combination of capacity payments and arbitrage revenue has created a highly profitable market model, serving as a blueprint for global renewable energy integration and grid stability strategies [1]. Chilean solar began to grow properly a little over a decade ago, thanks largely to the remuneration scheme the government provided for small-scale plants [1].
Legislative Catalyst
Most of the utility-scale segment focused on installing a lot of capacity around the center of the country, close to the capital and the main demand hub [1]. Meanwhile, the country is building a transmission line to connect capital city Santiago and other demand centers with the north of the country [1]. This infrastructure development is critical to managing the influx of renewable energy generated in the north and transported to demand centers [1]. The regulatory framework established in 2024 remains the primary driver for this accelerated deployment timeline [1].
Corporate Investment and Financing
Engie Chile is seeking a US$400 million loan from the International Finance Corporation (IFC) to fund battery energy storage systems (BESS) and grid-reliability projects [2]. Projects involved include the 119 MW BESS Tocopilla, which became operational as of 1H26, and the 140 MW BESS Lile, which is under construction [2]. In August 2026, Engie commissioned the 199 MW BESS Libélula and the 48 MW BESS Los Loros, contributing to the national capacity target [2]. Engie Chile’s installed capacity was 3.0 GW as of June 2026 and is projected to reach 3.6 GW in 2027 [2].
Corporate Investment and Financing
The company targets a full coal-fired generation exit in 2027, with a portfolio composition of 71% renewables/batteries and 29% natural gas following the transition [2]. Engie Chile is evaluating the installation of 2 GW of new capacity between 2027 and 2030, contingent on project profitability [2]. Financial history includes a US$400 million sustainability-linked loan from the IFC in 2023 and a US$400 million loan facility from CAF (Banco de Desarrollo de América Latina) in 2025 [2]. The CFO noted a strong pipeline of profitable assets critical to integrating Chile’s rapidly growing renewable base [2].
Regional Context and Projections
Latin America’s cumulative energy storage capacity is projected to surge from 2.5 GW in 2025 to 34 GW by 2035, representing a 30% CAGR [3]. This growth represents a percentage increase of 1260 over the decade, driven by renewable curtailment and ageing infrastructure [3]. Chile, Mexico, Brazil and Argentina are emerging as key markets, while the Dominican Republic is advancing storage deployment through regulatory mandates [3]. Chile maintains regional leadership in battery energy storage systems (BESS), though price cannibalisation in the northern grid is identified as a risk to project arbitrage revenues [3].
Regional Context and Projections
Wood Mackenzie highlights the need for bankable revenue mechanisms, clear regulations, financing access and faster permitting to convert the growing project pipeline into operational capacity [3]. Countries that build bankable revenue frameworks will attract the investment needed to sustain growth well beyond the current policy-driven wave [3]. Mexico intends to award more than 3 GW of storage capacity by 2030 via recent initiatives, including priority proposals and joint development calls with the Federal Electricity Commission [3]. Argentina has awarded 1.3 GW of standalone storage capacity through recent competitive tender rounds, with project operations expected to commence in 2027 [3].
Grid Infrastructure and Future Outlook
Rising renewable energy curtailment, accelerating storage tenders and ageing transmission infrastructure are driving the region’s growing demand for BESS [3]. Brazil has a dedicated battery tender scheduled for December 2026 to support capacity additions from 2028 onwards [3]. The Dominican Republic has set a target of 500 MW of energy storage capacity by 2030, supported by a 50% storage-to-solar capacity mandate [3]. As Chile approaches the end of 2026, the focus shifts to sustaining momentum through grid modernization and continued regulatory support [1][3].
