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.

Libya built over 4,000 kilometers of underground pipelines to bring water from the Sahara to coastal cities in a project that the government itself called the Eighth Wonder of the World.

He transformed an abandoned plastic water tank into an underground house in the “hobbit hole” style, using only repurposed pallet wood, without heavy machinery or expensive labor.

Toyota launches “family hybrid van” with 7 or 8 seats, 1.8 hybrid engine, fuel consumption of up to 23.8 km/l, and a price equivalent to about R$ 104,000 without taxes, below the Tiggo 8 Pro Plug-in Hybrid sold in Brazil: meet the Noah Hybrid 2026 in Japan.

China transforms desert-devastated area into the world’s largest artificial forest, planting trees for 60 years, blocking sand that reached Beijing, and creating a “green lung” of 92,000 hectares in a region once considered lost.

With 70 tons of rock removed by hand and an 800-year-old abandoned cave, a former businessman transforms a dark shelter into a modern home carved in the heart of the forest.

Scientists have created a material six times lighter than air, 75 times lighter than styrofoam, and that becomes stronger the more it is compressed: aerographite seems impossible, but it can reinforce structures, batteries, and satellites.

Brazil has 8.4 million illiterates and more than half live in the Northeast, where 10.6% of people cannot read or write a simple note, compared to 2.3% in the Southeast, according to the Pnad Contínua Educação 2025 from IBGE.

A black box made of steel and concrete, about 16 meters in size, is being installed in a remote location on Earth to record in real-time the progress of the climate crisis and the potential collapse of the planet, with data from space and meteorological agencies worldwide.

Peugeot 408 Griffe 2015 combines a turbo engine, 0 to 100 km/h in 8.3 seconds, a 526-liter trunk larger than many compact SUVs, leather, multimedia, cruise control, and a sunroof, but it remains off the radar among fully equipped used cars.

A great economist predicted that by 2030 we would work only 15 hours a week, and John Maynard Keynes’s forecast is about to fail miserably almost 100 years later.

Brazilian scientists are simultaneously advancing two research projects on clean hydrogen and driving solutions that could transform the energy matrix, enhance industrial competitiveness, and accelerate large-scale emission reduction targets.

Advancement in renewable energy: A R$ 150 million project launched by Petrobras and Finep aims to create state-of-the-art electrolyzers for green hydrogen, strengthening national research and preparing Brazil to compete in a billion-dollar energy market.

Illiterate or semi-literate grandmothers were trained to repair solar systems, open rural workshops, and light up homes that still depended on kerosene.

The world has bet on green hydrogen as the fuel of the future, but now faces the side effect: producing 1 kilogram requires about 9 liters of ultrapure water, and the largest projects on the planet are precisely in the driest regions of the Earth, where water is already scarce for people.

Africa has about 500,000 cell towers and most still burn diesel to operate, while companies rush to cover antennas with solar energy and avoid signal blackouts.
