In alignment with NREL's mission to accelerate the deployment of advanced energy solutions, NREL partnered with the National Energy Secretariat, subnational energy secretariats, utilities, regulators, and universities in Argentina on energy sector-wide modeling and analyses in several areas related to their energy sector planning.

NREL is supporting the National Energy Secretariat as well as the Provincial Government of San Juan to develop a national roadmap for demand side management, including tariff reform strategies that encourage implementation of demand side management measures and reduce peak load during the summer and winter.

In Tierra del Fuego, Argentina, NREL analyzed energy system alternatives, including increasing integration of wind power and long-duration storage as key solutions for cost-effective energy reliability, with mainland interconnection offering a competitive alternative, despite challenges related to terrain and resource availability.

In La Pampa, NREL modeled distributed photovoltaic systems to improve voltage drops and support energy diversification targets and storage potential in the Neuquén Basin to inform national planning and cost curves, and analyzed building envelope and retrofit improvements to enhance efficiency and reduce costs. These efforts reduce market barriers and inform investment in high-impact technologies aligned with national energy resilience goals.

Belize

NREL—in partnership with the Millenium Challenge Corp., Belize Public Utilities Commission, Belize Energy Limited, and Ministry of Public Utilities, Energy, Logistics, and E-Governance—developed a nodal production cost model and associated technical training for stakeholders to analyze the value of potential energy storage investments to support resilience and lower energy costs for Belize. This initiative exemplifies NREL's role in equipping countries with analytical tools that reduce technology risk and support advanced energy planning.

Brazil

NREL is supporting the Ministry of Mines and Energy to develop a framework for evaluating the socioeconomic impacts of improving energy access for isolated communities in the Amazon through deployment of distributed energy minigrids.

Through a broader regional program, NREL is also providing technical assistance to Brazil's Energy Research Office and the Brazilian Electricity Regulatory Agency to strengthen regulations and modeling to support procurement of utility energy storage systems in Brazil.

The Global Power System Transformation (G-PST) Consortium, in partnership with Brazil's National System Operator, hosted two technical roundtables on modeling inverter-based resources and technical requirements for grid-following and grid-forming technologies. Experts from leading institutions shared best practices to help Brazil's National System Operator enhance grid stability and integrate more renewable energy.

In addition, NREL is collaborating with Brazil's Energy Research Office and the Ministry of Mines and Energy on a techno-economic analysis to estimate the production cost of hydrogen from sugarcane bagasse and straw, and facilitating collaboration across U.S.-Brazilian universities to strengthen curriculum development on hydrogen. These engagements promote innovation, supply chain diversification, and long-term investment in resilient energy infrastructure.

Chile

To expand access to affordable, reliable, and secure energy in Chile, NREL helped the Chilean Renewable Energy Center develop a concentrating solar power solicitation, advancing disaster relief efforts, and facilitating advanced energy working groups. We also contributed to the creation of a Latin American gateway in Spanish on OpenEI and provided training on analysis tools to enhance Chile's innovation investment program.

Chile is advancing its workforce and economic opportunities alongside energy system development. A multi-laboratory team, including NREL, conducted an analysis of workforce and economic opportunities in Tocopilla, Chile. This collaboration also fostered a Sister City relationship between Tocopilla and Lawrence, Kansas, to exchange information on energy system advancements. These initiatives help scale capacity, strengthen energy infrastructure, and create new economic opportunity.

Colombia

NREL supported several Colombian ministries in energy planning, grid operations, electromobility, and energy communities, including refining interconnection standards, advancing minigrids, analyzing rooftop solar, providing regulatory support for hydrogen and geothermal, and mobilizing renewable energy investment. We also provided technical training using NREL's open-source tools to Colombia's ministries and industry stakeholders to strengthen local expertise in analyzing energy development and integration opportunities.

Additionally, NREL supported infrastructure resilience planning, including workforce training for distributed energy integration and technical guidance for Providencia Island's energy system reconstruction following Hurricane Iota. Since 2017, we have assisted Colombia in implementing renewable energy auctions, and analyzing renewable energy opportunities, leading to the deployment of 2.5 GW of new generation capacity.

NREL is collaborating with Colombian ministries, industry associations, and private sector entities to build technical capacity for evaluating energy solutions aligned with national priorities.

Through G-PST's partnership with Colombia’s system operator, XM, and in collaboration with the Electric Power Research Institute, NREL developed a roadmap to modernize XM's control room operations, enhance grid management, and facilitate peer-learning exchanges with international system operators. These efforts contribute to secure, modern energy systems.

Costa Rica

NREL helped develop a regional energy efficiency center in Costa Rica, located at the University of Costa Rica, which will collaborate with government agencies to expand local knowledge and provide training and services on energy innovations.
