Aneel Authorizes Casa dos Ventos to Start Operations of New Wind and Solar Parks in the Northeast, Expanding Renewable Energy Supply and Accelerating the Electrical Transition in the Country

On November 25, 2025, Aneel authorized Casa dos Ventos to start operations of new renewable energy projects in the Northeast. Highlights include the photovoltaic plant Fótons de Santa Larissa 4, with a capacity of 50 MW, in Bahia, and units from the wind complex Ventos de São Rafael, in Rio Grande do Norte. This decision strengthens the Brazilian energy matrix and marks a step forward in the energy transition.

Aneel Authorizes Casa dos Ventos to Operate in the Northeast

The National Electric Energy Agency (Aneel) authorized Casa dos Ventos to start operational tests of the photovoltaic plant Fótons de Santa Larissa 4, with an installed capacity of 50 MW, located in the municipalities of Morro do Chapéu and Várzea Nova in Bahia. The dispatch was published in the edition of the Official Gazette of the Union (DOU) on Tuesday, November 25.

In addition, the company received approval to begin tests of UG1 of the Wind Farm Ventos de São Rafael 6, with 4.5 MW, located in Lajes Pintadas and São Tomé, in Rio Grande do Norte, and UG12 of the Wind Farm Ventos de São Rafael 9, also 4.5 MW, in São Tomé.

Wind and Solar Parks in the Northeast

The Northeast is currently the largest hub for renewable energy in Brazil. The region accounts for about 90% of the installed capacity of wind energy and has been rapidly growing in solar generation.

The factors explaining this leadership include:

High solar incidence throughout the year.
Constant and intense winds, ideal for wind turbines.
Expansion of transmission infrastructure, connecting parks to the National Interconnected System.

The Northeast consolidates itself as a protagonist in the Brazilian energy transition. According to the Energy Research Company (EPE), more than 83% of the Brazilian electric matrix is already made up of renewable sources. With the new projects from Casa dos Ventos, this participation is expected to grow even further.

The start of operations of the projects represents:

Reduction of dependence on fossil sources.
Contribution to decarbonization goals.
Greater energy security for the country.

Each new wind or solar park strengthens Brazil’s commitment to sustainability.

Other Companies Also Receive Authorization from Aneel

Kroma Energy Trading received authorization to begin tests of the photovoltaic plant UFV Acomais, with a capacity of 0.42 MW, located in Jaboatão dos Guararapes, Pernambuco.

The commercial operation of UFV Elimari Regio I, with 0.3 MW, from Merx Energia, located in Rio Grande do Norte, was also authorized by Aneel, along with tests of UFV Ferreira Costa Paralela, with 0.6 MW, from Trifase Energia, installed in Bahia.

Additionally, the company Produção de Peças Ltda (Usipart) received approval to start tests of UFV Usipart, with a power of 0.15 MW, located in Xanxerê, in the state of Santa Catarina.

Economic and Social Benefits

In addition to generating clean energy, the projects can bring positive impacts to the economy and society:

Creation of direct and indirect jobs during construction and operation.
Interiorization of wealth, with investments in municipalities in the hinterlands and semi-arid regions.
Attraction of industries and data centers, seeking renewable energy to reduce costs and emissions.

These factors contribute to regional development and the inclusion of local communities in the productive chain.

Casa dos Ventos as a Protagonist

Casa dos Ventos is one of the largest developers of renewable energy projects in Brazil. With dozens of projects in operation and under construction, the company positions itself as a benchmark in the sector.

Among recent highlights is the Babilônia Centro Wind Complex, in Bahia, with an installed capacity of 553.5 MW and an investment of R$ 4.2 billion. Casa dos Ventos’ work reinforces the role of the private sector in expanding renewable energies.

Future Perspectives for the Sector

The authorization from Aneel in November 2025 paves the way for new investments and increases confidence in the clean energy sector. Brazil should continue attracting national and international capital, solidifying its position as a leader in renewable energy in Latin America.

With the progress of wind and solar parks in the Northeast, the country strengthens its strategic position in the global energy transition. The future points towards an increasingly sustainable, competitive, and decentralized matrix.

Future Perspectives for the Sector

With billions in loans, China is rebuilding Nigeria’s railway network from scratch, abandoning the British colonial tracks that have turned to scrap and creating a corridor of over 1,300 km to take the load off the roads of Africa’s largest economy.

A British company has installed in the middle of the ocean the world’s first floating platform that generates electricity 24 hours a day from the temperature difference between the surface and the depths of the Atlantic, without relying on wind or sun.

China is building an artificial island in the middle of the sea, covering 20 km², to construct the largest offshore airport in the world, the Dalian Jinzhouwan. This $4.3 billion project is anchored on more than 3,000 pillars embedded in the rock beneath the ocean and is scheduled to open in 2035.

Forget petroleum-based asphalt: a Scottish company transforms 684,000 plastic bottles into one kilometer of road that is 60% more resistant and up to 10 times more durable, and the technology has already started replacing traditional asphalt in more than 30 countries.

A robot named Walter does the work of five bricklayers per hour and can save the construction industry, where the average age of professionals is 46 years and almost no one wants to learn the trade anymore, in the United Kingdom.

Austrian engineers have developed an inflatable concrete technology that transforms flat slabs into domes using only air pressure, eliminating scaffolding and temporary forms, and potentially changing the way bridges, tunnels, and curved roofs are constructed worldwide.

The James Webb telescope spotted a planet 700 light-years from Earth with mornings full of sand clouds and nights with clear skies, the temperature difference between the two hemispheres reaches an impressive 170 degrees.

The coastal El Niño is not the classic El Niño, but it already raises a question in Brazil: can the phenomenon alter rain, heat, and winter?

The commander of the Brazilian Army publicly admitted that the country now perceives real threats in South America, something that, according to him, did not exist in the past, and advocates for the increasing use of drones and technology to secure the borders.

In China, even those who beg on the street already have a QR Code, paper money has practically disappeared from daily life in just ten years, and the entire country has come to live on invisible payments via mobile phones.

Brazil will harvest a record crop of up to 357 million tons of grains, but it does not have the capacity to store a large part of it. The storage deficit has reached the highest level in history and is equivalent to almost the entire production of Argentina.

Scientists considered detonating 213 nuclear bombs in the Sahara to create an artificial sea the size of El Salvador, with each explosion being a hundred times more powerful than the Hiroshima bomb, and the goal was to generate more energy than Egypt’s largest hydroelectric plant.
