Minister Alexandre Silveira Announced That Brazil Intends to End Socio-Environmental Spending at Itaipu by 2027. The Proposal, Advocated as a Way to Lower Energy Costs, Divides Opinions Among Lawmakers and Rekindles the Debate on the Future of the Treaty With Paraguay.
During a hearing at the Foreign Relations and National Defense Commission of the Chamber of Deputies, Minister of Mines and Energy Alexandre Silveira stated that the Brazilian government intends to advocate for the end of socio-environmental spending at Itaipu starting January 2027. The measure, according to him, aims primarily to reduce the price of electricity for Brazilian consumers.
“Let us end, starting in January 2027, the socio-environmental spending to reduce the price of energy in Brazil,” declared the minister.
The statement was made in the context of negotiations between Brazil and Paraguay concerning Annex C of the Itaipu Treaty, a document that establishes the financial and commercial bases of the binational partnership. The revision of this annex is considered one of the most sensitive points in the relationship between the two countries and could redefine how the costs and profits of the hydropower plant will be divided in the coming years.

Itaipu and the Impacts of Socio-Environmental Programs in Brazil
Since its inception, Itaipu Binacional has invested in projects aimed at environmental preservation, socio-environmental education, and sustainable development of the communities located in its surroundings. These resources, according to lawmakers, are essential for the protection of ecosystems and water sources, especially in the border region between Paraná and Mato Grosso do Sul.
Deputy Welter (PT-PR) emphasized the importance of the initiatives financed by the power plant:
“These socio-environmental actions at Itaipu help conserve soil and protect the lake from siltation.”
He noted that all municipalities in Paraná and 35 from Mato Grosso do Sul use part of these resources for environmental preservation and rural infrastructure projects.
On the other hand, some advocate for redirecting these funds to strengthen the national energy matrix. Deputy Luiz Philippe de Orleans e Bragança (PL-SP) questioned the purpose of the investments:
“What is Itaipu for? To carry out socio-environmental projects or to ensure energy security, reduce the cost of electricity, and invest in new energy sources?”
The divergence among lawmakers reveals the challenge of balancing sustainability and economic efficiency, especially in light of the energy transition goals that Brazil aims to accelerate by the end of the decade.
The renegotiation of Annex C, scheduled to take effect in 2027, will be crucial for the future of the Itaipu plant. The topic has been treated strategically by both the Brazilian and Paraguayan governments, which seek to redefine the model for the distribution of costs and revenues from the energy produced.
In addition to financial issues, Silveira also addressed other significant topics for the Brazilian energy sector, such as the expansion of renewable sources, energy storage, and the critical minerals needed for the high-tech industry.
According to the minister, the government plans to hold an auction for energy storage in December, aiming to reduce the impact of the mismatch between electricity generation and consumption, especially from intermittent solar and wind sources.
Expansion of Infrastructure and Advances in Nuclear Energy
Alexandre Silveira also highlighted that the expansion works of the transmission network, which began in 2023, are expected to be completed by 2028, allowing greater flow of renewable energy produced in the country.
Another relevant point was the reorganization of the Brazilian nuclear sector. The minister criticized the halt of projects and advocated for the resumption of strategic investments:
“Brazil, which holds the seventh-largest uranium reserve in the world, cannot continue with the sector paralyzed. Angra 1 was built in eight years. We have been stalled with Angra 3 for 30 years. This is unacceptable.”
For him, the adoption of small nuclear reactors may be the solution for the 200 isolated systems in the Amazon, regions that still lack transmission infrastructure. Additionally, Silveira suggested discussing the strategic use of nuclear energy for defense, which, according to him, would require constitutional changes.
The minister also revealed that he was invited to discuss critical minerals policy with the United States Secretary of Energy, Chris Wright, and announced the creation of the National Mineral Policy Council, which will be responsible for defining guidelines for the sustainable use of these resources.
In the same vein, Silveira mentioned the interest of international companies to invest in Brazil, such as the possible establishment of a TikTok data center in Ceará, a state known for its solar and wind energy production. This measure, he stated, would help balance the supply and demand for renewable energy in the country, creating new technological development hubs.
