Brazil reveals vast potential in small-scale hydroelectric power, with 1,070 projects under review.
The Brazilian energy sector is demonstrating significant expansion potential through small-scale hydroelectric plants. Recent data indicates that the country has 1,070 projects for Hydroelectric Generating Stations (CGHs) and Small Hydroelectric Plants (PCHs) in various stages of study and development, awaiting operational authorization. These ventures represent a potential installed capacity of an impressive 13.4 GW, a volume that significantly approaches the total generation capacity of the renowned Itaipu power plant.
This large-scale initiative highlights the growing importance of smaller water-based energy sources for diversifying the national energy matrix. The analysis, based on information from the National Electric Energy Agency (Aneel), reveals a promising outlook for increasing the supply of clean and renewable energy in the country. A large portion of these projects has already made significant progress in their regulatory processes, pointing to a promising future for distributed generation and regional energy supply.
Regulatory Progress and Generation Potential
Among the 1,070 projects under review, 401 are already in the “available axis” phase, indicating that areas with hydroelectric potential have been identified and are open to interest from new developers. This stage is crucial for mapping and ensuring the viability of future sustainable energy projects.
Projects in Advanced Stages
The research highlights that the majority of these projects, specifically 601 units (representing 56% of the total), have already achieved the Executive Summary Adequacy Registration Dispatch (DRS-PCH). This stage, managed by Aneel, signals that the submitted projects comply with regional energy usage guidelines and represent a significant step toward implementation. Together, these more advanced projects already total a considerable capacity, approaching the total amount of CGHs and PCHs currently in operation.
The Current Small Hydroelectric Landscape
Currently, Brazil has a consolidated fleet of 433 PCHs and 711 CGHs in full operation. Combined, these units generate nearly 7 GW of regulated power, contributing significantly to energy security and the diversification of the Brazilian matrix. The continuous expansion and the substantial volume of projects under study demonstrate the country’s commitment to renewable sources to meet growing energy demand.
