Petrobras Advances in Energy Transition with Project to Install a Solar Farm in Amazonas Aiming to Supply Transpetro Units with Clean Energy and Reduce Diesel Use in Remote Areas
The announcement made by the president of Transpetro, Sérgio Bacci, during the Rio Pipeline conference this Tuesday (9), marks a new step for Petrobras towards energy transition. The Brazilian state-owned company is studying the purchase of a solar power plant to supply its logistics units in the state of Amazonas, particularly the terminal in Coari, located in the heart of the Amazon rainforest.
The initiative is aligned with the company’s environmental commitments and represents a strategy to reduce operational costs, decrease dependence on fossil fuels, and expand the use of renewable sources in its operations.
Petrobras Strategy: Solar Energy as a Sustainable Solution
The proposal to acquire a solar farm aims to replace the current diesel fuel supply model with a clean and sustainable alternative. According to Bacci, the project is being developed in conjunction with Petrobras’ energy transition and sustainability department, led by Angélica Laureano.

Brazil reaches historic milestone in solar energy: Sector surpasses 2 million accumulated green jobs and generates billions in the national economy even under market pressure.
-
Minas Gerais takes the lead in renewable energy: State surpasses historic mark of 14 GW in solar energy generation in MG and consolidates dominance in the Brazilian electric sector.
The primary objective of this measure is the reduction of operational costs, in addition to aligning the company with the increasingly demanded ESG (environmental, social, and governance) practices by the market and society. The replacement of diesel with solar energy also contributes to the reduction of greenhouse gas emissions, reinforcing Petrobras’ commitment to decarbonization.
Transpetro and the Expansion of Solar Energy in Logistics Terminals
Transpetro, Petrobras’ subsidiary responsible for the logistics of transporting and storing oil and its derivatives, already operates two terminals powered by solar energy: one in Guarulhos (SP) and another in Belém (PA). The inclusion of the Coari terminal in Amazonas represents a significant advancement in the company’s decarbonization strategy.
The expectation is that the project will be implemented by 2026, although data on the necessary energy capacity or the projected investment has not yet been disclosed. The initiative reinforces Transpetro’s role as an innovation agent within the Petrobras group.
Technical Feasibility of the Solar Farm in Amazonas
The installation of a solar farm in Amazonas raises important questions about technical feasibility and environmental impact. Despite its vast vegetation cover, the Amazon region has a high solar radiation index, which favors photovoltaic generation.
According to data from the National Institute for Space Research (INPE), the state of Amazonas receives an average of 4.5 to 5.5 kWh/m² per day of solar irradiance, making it suitable for medium- and large-scale solar energy projects.
However, the logistics of transporting and installing equipment in remote areas requires detailed planning. Local infrastructure, climate conditions, and environmental preservation are factors that must be considered to ensure the project’s feasibility.
Additionally, replacing diesel with solar energy could significantly reduce CO₂ emissions. According to studies by SEEG, each liter of diesel burned emits about 2.6 kg of carbon dioxide. This change represents a significant environmental gain for the region.
Solar Energy in Brazil: Accelerated Growth and Opportunities
Brazil has stood out on the global stage for the expansion of solar energy. According to the Brazilian Association of Photovoltaic Solar Energy (ABSOLAR), the country exceeded the mark of 37 GW of installed capacity in 2025, just in distributed generation.
The adoption of solar power plants by large companies like Petrobras reinforces the trend of energy decentralization and the use of renewable sources. The purchase of Solar Farms by corporations has become a common practice, allowing for greater control over supply and cost predictability.
Additionally, the photovoltaic sector has generated thousands of direct and indirect jobs, contributing to the economic and technological development of the country. The North region, in particular, has the potential to become a strategic hub for solar generation, taking advantage of its vast territorial extension and high radiation levels.
Governance and Partnerships in Petrobras’ Energy Transition
The energy transition department at Petrobras has played a central role in coordinating sustainable projects. Since the departure of Mauricio Tolmasquim in May 2025, Angélica Laureano has taken the lead in the area, promoting initiatives aligned with the company’s Strategic Plan.
The partnership with Transpetro for the acquisition of a solar farm in Amazonas is a clear example of the integration between operational and strategic areas. This synergy is essential to ensure that renewable energy projects are technically and economically viable.
Petrobras’ corporate governance has sought to incorporate environmental and social criteria in its decisions, strengthening the company’s image before investors and stakeholders. The adoption of solar energy is one of the most promising fronts of this transformation.
Economic and Operational Benefits of Solar Energy for Transpetro
The replacement of the fossil energy matrix with renewable sources brings direct benefits to Petrobras and Transpetro:
- Reduction of costs with fossil fuels;
- Less dependence on diesel generators in remote areas;
- Decreased expenses with maintenance and supply logistics;
- Enhancement of institutional image before investors and society;
- Potential generation of carbon credits for commercialization.
Furthermore, the use of solar energy can increase the operational efficiency of logistics terminals, ensuring greater stability in supply and less vulnerability to fluctuations in international fuel prices.
Sustainability and Environmental Responsibility in Amazonas
Petrobras’ initiative to install a solar power plant in Amazonas also has relevant social and environmental implications. The region is marked by logistical challenges and the need to preserve biodiversity. The adoption of clean energy sources contributes to mitigating the environmental impacts of industrial operations.
The solar farm planned to supply the Coari terminal could serve as a model for other installations in the North region, promoting sustainable development and generating local jobs. The training of regional labor and the encouragement of a green economy are aspects that strengthen the positive impact of the project.
Solar Energy as a Vector of Transformation at Petrobras
Petrobras’ decision to study the purchase of a solar farm to supply Transpetro units in Amazonas, announced on September 9, 2025, represents a milestone in the state-owned company’s journey towards energy transition. The initiative is aligned with global decarbonization goals and reinforces the company’s role as an agent of transformation in the Brazilian energy sector.
With implementation scheduled for next year, the project could solidify the presence of solar energy in Petrobras’ operations, reduce operational costs, and contribute to environmental preservation in the Amazon. The integration between corporate strategy and social-environmental responsibility is a promising path for the future of energy in Brazil.
