Sobradinho Hydroelectric Power Plant, Bahia, Brazil | 1,050 MW Facility

Sobradinho is a large hydroelectric power plant situated in the state of Bahia, Brazil, on the São Francisco River. With a capacity of 1,050.3 MW, it ranks among the significant hydropower facilities in the country, contributing to Brazil's predominantly renewable energy matrix. The plant is operational and plays a vital role in supplying electricity to the Northeast region. As a hydroelectric plant, Sobradinho operates without direct fuel combustion, resulting in minimal emissions of CO2, SOx, and NOx compared to thermal plants. The facility utilizes conventional hydropower technology, typical for large-scale projects in Brazil. The regulatory framework governing such plants includes federal environmental licensing and water use permits, overseen by agencies like ANEEL and IBAMA. Sobradinho's reservoir also serves multiple purposes, including water supply, irrigation, and flood control, enhancing its regional significance. The plant's location in the semi-arid Northeast makes it a critical asset for energy security and economic development. Its operation aligns with Brazil's commitment to clean energy and climate goals.

The Sobradinho plant is situated in the semi-arid region of Bahia, where water availability is a key environmental concern. The reservoir created for hydropower generation supports local ecosystems and provides water for agriculture and human consumption. However, large reservoirs can alter riverine habitats and affect fish migration. The plant's carbon footprint is low due to its renewable nature, but methane emissions from decomposing organic matter in the reservoir may occur. Proximity to populated areas is moderate, with the city of Sobradinho nearby.
