How Revenue Hunger Threatens Brazil’s Renewable Future

By Daniel Pansarella

Brazil is currently facing a paradox that challenges both economic and environmental logic. While the world accelerates the energy transition and consolidates renewable sources as the cornerstone of sustainable development, the country appears to be moving in the opposite direction adopting measures that make clean energy more expensive while favoring the old and inefficient fossil fuel industry.

The recent increase in taxation on solar equipment and energy storage systems is not merely a policy mistake; it is a clear symptom of short-term thinking that sacrifices the future in favor of immediate revenue.

The publication of Resolution GECEX No. 871/2026, which alters import tariffs on solar inverters, represents the latest chapter in this series of setbacks. The measure directly impacts essential equipment such as on-grid, string, and hybrid inverters, adding to previous tax increases on photovoltaic modules (25%) and batteries (from 16–18% to 20%). What was once a favorable environment for innovation and sustainability has turned into a maze of legal uncertainty and rising costs.

The Fallacy of Protecting National Industry

The official justification for these tariff increases is the supposed “protection of national industry.” However, this narrative does not withstand deeper analysis. Brazil simply does not have a robust industrial chain capable of meeting domestic demand for high-tech inverters or large-scale lithium battery production.

By heavily taxing these products, the government is not protecting a nascent industry—it is penalizing consumers and making clean energy projects unfeasible. Without a clear industrial development plan, tariff protection becomes nothing more than a disguised tax imposed on society.

Meanwhile, other countries are moving in the opposite direction, reducing taxes on solar equipment and batteries, clearly signaling that renewable competitiveness is a strategic priority.

A Devastating Impact on the Sector

The numbers speak for themselves. Only 10% of solar integrators founded before 2016 are still active in Brazil today. In 2025, the average number of employees per company dropped from seven to six, and 68% of companies operate with teams of four or fewer people.

Commercial proposals have fallen by 19%, with an average of 21 monthly quotes per company, compared to 43 in 2023.

In the utility-scale segment, the outlook is equally concerning. Renewable energy companies are downsizing operations and laying off workers. Billions of reais have been lost due to generation curtailment imposed by the system operator. Wind industry manufacturers have shut down factories, and major utilities have publicly stated they will not invest in new solar and wind projects in Brazil until regulatory and operational issues are resolved.

Capital Flight to Neighboring Countries

While Brazil struggles with regulatory contradictions, countries like Chile, Argentina, and Colombia are attracting the capital that should be flowing here.

Chile and Argentina already have advanced legislation and auction mechanisms for battery storage (BESS), with operational projects in place. Argentina has introduced reforms offering regulatory stability, tax incentives, and access to foreign currency for up to 30 years.

Chile has established itself as a regional leader in energy storage, with a mature regulatory framework that properly compensates storage systems. Colombia, in turn, has implemented programs to expand energy access and has achieved record solar generation, surpassing coal a historic milestone.

The Weight of the Fossil Lobby and Revenue Urgency

The true motivation behind these measures appears to lie in two reinforcing forces: the urgent need to increase tax revenue and the disproportionate influence of the oil and gas industry.

With a projected fiscal deficit in the tens of billions, the government is aggressively seeking new revenue sources. Tax increases on imported goods are expected to generate billions, but at the cost of undermining a strategic sector.

Meanwhile, fossil fuels continue to benefit from privileges and influence. Recent thermal energy auctions, which contracted diesel-based generation, demonstrate that carbon-intensive interests still shape policy decisions.

Impact on Growth, Society, and Future Generations

Brazil’s solar sector is a proven engine of development, generating over 2 million jobs and attracting nearly R$300 billion in investments since 2012. Solar energy now represents 22% of the country’s electricity matrix.

Distributed generation has democratized access to energy, benefiting millions of households, small businesses, and farmers.

At the same time, Brazilian society is increasingly committed to sustainability. The rapid growth of electric and hybrid vehicles reflects a cultural transformation that is irreversible.

However, recent policies threaten to halt this momentum. Rising costs compress margins, restrict credit, and discourage investment. Hybrid solar plants and storage systems critical for grid stability are at risk of becoming economically unviable.

A Call for Strategy and Long-Term Vision

Brazil has a historic opportunity to lead the global energy transition. But this requires coherent, predictable, and long-term public policies.

The current contradiction where sustainability is praised in discourse but penalized in practice undermines investor confidence and damages Brazil’s international credibility.

The country must shift from a short-term revenue-driven approach to a long-term strategy that fosters innovation, competitiveness, and clean energy adoption.

Capital is seeking safe destinations. If Brazil fails to provide regulatory stability and legal certainty, billions in investments will flow to neighboring countries instead.

We cannot allow fiscal short-sightedness and outdated interests to prevent us from building the sustainable future that Brazil and future generations deserve.
