São Domingos Hydroelectric Power Plant | Brazil | 14.3 MW

São Domingos is a hydroelectric power plant located in Brazil, with a capacity of 14.3 megawatts (MW). As a small-scale hydro facility, it plays a role in the country's diverse energy mix, which relies heavily on hydropower. The plant is operational and contributes to the regional grid. Hydroelectric plants like São Domingos operate by converting the energy of flowing water into electricity. In Brazil, hydropower is the dominant source of electricity, accounting for over 60% of the national capacity. The regulatory framework for hydroelectric plants in Brazil includes environmental licensing by IBAMA and compliance with the National Water Agency (ANA) regulations. Small hydro plants (below 30 MW) benefit from simplified licensing procedures under the Brazilian Electricity Regulatory Agency (ANEEL). As a renewable energy source, São Domingos helps reduce greenhouse gas emissions compared to fossil fuel plants. However, hydroelectric projects can have local environmental impacts, such as changes to river ecosystems and water flow. The plant's location in the state of Goiás, near the border with Bahia, places it in a region with significant agricultural activity, where water resources are important for both energy and irrigation.

Hydroelectric power generation in Brazil is generally considered low-carbon, but it can affect local aquatic ecosystems and water availability. The São Domingos plant, with a capacity of 14.3 MW, is a small run-of-river or reservoir-based facility. Its environmental footprint depends on the specific design and location. In the Cerrado biome, where the plant is situated, water resources are crucial for biodiversity and agriculture. The plant's operation must balance energy production with maintaining river flows and fish passage.
