Who Can Participate and Which Projects Will Be Accepted
Proposals that reduce energy consumption can participate. These include modernization of lighting systems, replacement of old equipment, improvements in air conditioning, and implementation of solar energy plants.
Additionally, the call includes projects with energy storage in batteries. This is one of the main novelties of this year. The battery systems, known as BESS, must be associated with distributed generation, such as photovoltaic installations.
In practice, this means that solar energy projects will be able to store excess generated during the day for later use. This measure tends to increase efficiency and reduce waste.
Deadlines, Criteria, and Supervision
Proposals can be submitted until June 1, 2026, at 5 PM. Each state notice defines minimum and maximum amounts per project. Therefore, interested parties need to consult the specific rules of their region.
The selection will follow technical and economic criteria established by ANEEL. Among the points analyzed are the cost-benefit ratio, the potential for energy savings, and the counterpart offered by the customer.
After approval, projects will be monitored by Enel. Inspections, audits, measurements, and assessments are planned. The goal is to ensure that energy efficiency targets are truly met.
