After Aneel Decision in April 2025, Experts Discuss How the Hydroelectric Plant Can Contribute to the Security and Stability of Renewable Energy in the Country

The decision by the National Electric Energy Agency (Aneel), announced on April 2, 2025, to revoke the concession of the company São Pedro II Energia for the implementation of a wind farm in Piauí, once again brought to public debate the importance of stable renewable sources in Brazil.

According to the website Portal O Dia, the company failed to meet the obligations outlined in the contract, which led to the termination of the project concession. The case reinforces the need for a diversified energy matrix, where hydropower plays a strategic role.

The Structural Role of Hydropower in Brazil

Hydropower represents a significant share of electricity generation in Brazil. The availability of water resources in different regions allows the country to maintain a source of energy with low operational costs, reliable, and responsive to variations in demand.
Additionally, hydropower plants operate with flexibility, able to quickly adjust production according to the system’s needs. This capacity is fundamental to compensate for the intermittency of other renewable sources, such as solar and wind.

Challenges and Criteria for Hydropower Development

The construction of hydropower plants, however, requires detailed planning. Environmental impact assessments, analysis of water resources, and social participation are essential elements to ensure that benefits outweigh impacts.
Poorly conducted projects can affect ecosystems and local communities. Therefore, adopting strict technical and environmental criteria contributes to a more sustainable energy model.

Integration Among Renewable Sources

The integration of hydropower plants, solar farms, and wind farms allows for a more balanced and resilient energy matrix. While intermittent sources depend on climate, hydropower acts as a stabilizer for the system, providing support during low production periods of others.
Additionally, small hydropower plants (PCHs) have stood out for serving remote locations with lower environmental impact, offering more flexibility to the sector.

Innovation and Modernization of the Hydropower Sector

Moreover, the incorporation of new technologies enhances the efficiency of hydropower plants. For example, automation systems, remote monitoring, and digital environmental control contribute, thus, to a safer and more efficient operation.
With support from public policies and private investments, it is possible to upgrade old plants, reduce energy losses, and ensure a more responsible management of natural resources.
