In recent years, Brazil has faced significant challenges and opportunities in the electricity sector, driven by a growing demand for energy. The country’s electricity matrix, known for its predominance of renewable sources, is constantly evolving to meet the increasing consumption of electricity, which is essential for economic and social growth. However, this expansion also raises concerns about sustainability, existing infrastructure, and the need for ongoing investments.
The Brazilian electricity market is notable for its complexity and dynamism. With a population of over 200 million people and an economy heavily dependent on energy for sectors such as industry, agriculture, and services, Brazil needs to ensure a reliable and adequate supply of electricity. This challenge is heightened by the diversification of energy sources and the growing participation of renewable energies, such as wind and solar, which complement the traditional reliance on hydroelectricity.
The expansion of electrical infrastructure is crucial to support this growing demand. The country has been investing in transmission lines and new generation plants to avoid bottlenecks that could compromise supply security. Additionally, the modernization of electrical grids, with the incorporation of smart grid technologies, is seen as a solution to improve efficiency and consumption management, allowing for a more agile response to demand variations.
However, this expansion does not come without challenges. The market faces environmental, regulatory, and financial pressures. Environmental issues are particularly relevant, considering the impact of large infrastructure projects on sensitive areas like the Amazon. On the other hand, regulation needs to keep pace with changes, ensuring that the market remains competitive and that consumers have access to fair tariffs. Finally, financing new projects is a critical point, especially in an uncertain economic scenario.
As Brazil prepares for the future, the integration of renewable sources and adaptation to climate change are central themes. The country has significant potential to lead the global energy transition, but this will require an integrated approach that combines investments in technology, effective public policies, and efficient management of natural resources. The demand for electricity will continue to grow, and Brazil must be prepared to meet this need in a sustainable and resilient manner.
Electricity demand expected to grow 3.4% per year until 2034, says EPE
The Brazilian electricity market is in a state of rapid expansion, with projections confirming a trend of continuous growth in the coming decades. According to a recent study by the Energy Research Company (EPE), electricity demand in Brazil is expected to increase at an average rate of 3.4% per year until 2034. This scenario imposes the need for modernization and adaptation of the electricity system to ensure an adequate supply of energy and the continuity of service.
The demand growth will be driven by factors such as economic recovery, expansion of the consumer market, and greater electrification of sectors like transportation and industry. The EPE estimates that the industrial sector will account for about 36% of total electricity consumption by 2034, with the residential sector also playing an important role, especially due to the increased use of electrical appliances and thermal comfort in Brazilian homes.
Furthermore, EPE’s research indicates that energy load growth, including losses, will see an average increase of 3.3% until 2034, reaching 107 GW on average by the end of the period. The different hourly needs of consumers will shape the load curve, with peaks expected during the evening from June to August, and in the afternoon during the other months. These data highlight the need for a robust and well-distributed electrical infrastructure.
Another aspect highlighted by the study is the relevance of renewable energies in Brazil’s electricity matrix. Sources such as wind and solar are expected to continue their expansion, contributing to the diversification of the energy matrix and reducing the dependence on hydroelectricity, which faces challenges due to rainfall variability. Self-production of electricity, which currently accounts for about 12% of total consumption, is expected to grow by 2.4% per year, reaching 91.8 TWh in 2034. It is anticipated that investments in distributed generation (DG) and efforts to combat energy losses could result in a significant reduction in losses in the most favorable scenarios.
Regionally, demand growth will be more pronounced in the North and Northeast regions, reflecting the economic development in these areas and the need to expand electrical infrastructure to avoid supply bottlenecks. The EPE stresses the importance of continuous investments and effective public policies to ensure that demand growth is met sustainably without compromising the quality and reliability of the energy supply.
Brazil faces the challenge of balancing the expansion of supply with sustainability and efficiency, ensuring that the electricity market continues to be a pillar of support for the country’s economic and social development.
