The ENANDES project continues to make significant progress in strengthening weather, water and climate services for the energy sector across Latin America. Managed by the WMO Regional Office for the Americas in collaboration with WMO’s Energy Unit, the project is currently active in six countries including Chile, Colombia, Peru, Argentina, Ecuador and Bolivia, with a range of technical activities underway spanning training, applied research and regional tool development.
WMO Training Workshop on Energy and Nexus Services for Countries in Latin America
A milestone for the project was the successful completion of the WMO Training Workshop on Energy and Nexus Services for Countries in Latin America, held from 24 to 28 November 2025 in Asunción, Paraguay. The workshop brought together more than 20 participants from Chile, Peru, Argentina, Ecuador, Paraguay, Uruguay, Cuba, Costa Rica and Panama, with additional online participation from Colombia and Mexico. The programme covered best practices sharing, regional gap analysis for energy services, and hands-on technical sessions on solar radiation, wind and hydropower data.
Energy Mini-Projects and Climate Service Toolkit
Three technical activities are advancing in parallel to build operational capacity. In Chile, the energy mini-project on evaporation rate estimation for open water bodies with floating solar panels (March 2025–March 2026) has reached completion: the calibrated model has been incorporated into the platform of the Ministry of Energy of Chile for public use, and the final deliverable package, including an operational manual, open-source Jupyter Notebook codes and a recorded video, is currently under revision.
In Argentina, the mini-project on the evaluation and calibration of NWP model outputs for solar radiation using machine learning methods (October 2025–April 2026) has produced its first deliverable, a technical report finalized in collaboration with SMN and Universidad Nacional de Luján; the standard deliverable package is now in preparation.
Building on these two initiatives, a third activity, Conceptualizing a Climate Service Toolkit (CST) for the Energy Sector and Nexus (January–June 2026), is underway in collaboration with ENANDES countries and CIIFEN. The activity will produce a technical document outlining the design of an operational platform for integrated energy climate services.
National Renewable Energy Atlas for ENANDES and ENANDES+ Countries
The third phase of the WMO Renewable Energy Atlas project (January–June 2026) is supporting ENANDES and ENANDES+ countries in developing or updating their national atlases for wind, solar and hydropower resources. Following a kick-off meeting held on 18 March 2026, the project will proceed with data preparation and bilateral country consultations in April, co-development of the atlases in May and June, and a capacity development online session for delivery in June 2026. Up to seven country-specific atlas cases are planned, and the National Renewable Energy Laboratory (NREL) has been invited to contribute high-resolution projection data for the region. An interactive HTML landing page will also be developed to showcase results from across the WMO Atlas project.
In the coming months, ENANDES will further consolidate its technical outputs and regional partnerships. Planned activities include a regional webinar in June 2026 to disseminate mini-project results, a regional assessment of gaps and needs for energy services in April 2026, and under consideration, the translation of WMO Guidelines on National Atlases into Spanish and the publication of peer-reviewed journal articles on the Chile and Argentina mini-projects. WMO remains committed to supporting Latin American NMHSs in delivering actionable, science-based climate services for the energy sector.
The ENANDES project is continuing to advance energy-related activities and technical support in Latin America through mini-projects, regional planning, capacity development and renewable energy atlas work.
A key milestone under this work was the WMO Training Workshop on Energy and Nexus Services for Countries in Latin America, held from 24 to 28 November 2025 in Asunción, Paraguay. More than 20 participants attended from Chile, Peru, Argentina, Ecuador, Paraguay, Uruguay, Cuba, Costa Rica and Panama, with additional online participation from Colombia and Mexico. The workshop combined knowledge-sharing among countries with discussions on regional gaps and needs, the Climate Service Toolkit for energy and nexus, and practical sessions on ongoing energy-related activities.
The Chile mini-project, running from March 2025 to March 2026, focuses on evaporation rate estimation for open water bodies with floating solar panels. The Argentina mini-project, running from October 2025 to April 2026, focuses on the evaluation and calibration of an NWP model for solar radiation using machine learning methods. Another activity from January to June 2026 is focused on conceptualizing a Climate Service Toolkit for Energy Services in collaboration with ENANDES countries and CIIFEN.
From January to June 2026, ENANDES and ENANDES+ countries are also receiving support to develop or update national renewable energy atlases on wind, solar and hydropower. Countries listed under this phase include Chile, Colombia, Peru, Argentina, Ecuador and Bolivia. This work is being carried forward through country engagement, technical collaboration and planned capacity development activities in the first half of 2026.
