Big Bend Dam - 538.3 MW Hydroelectric Power Plant in the United States

Big Bend Dam is a hydroelectric power plant located in the United States, with a capacity of 538.3 MW. The facility is owned and operated by USACE-Omaha and is currently operational. As a hydroelectric plant, it harnesses the energy of flowing water to generate electricity, contributing to the renewable energy mix of the region. The plant operates under the regulatory framework of the United States, which includes federal oversight by agencies such as the Federal Energy Regulatory Commission (FERC) for hydroelectric projects. Environmental compliance is ensured through the Clean Water Act and the National Environmental Policy Act (NEPA), which require assessments of water quality and ecological impacts. The technology used is typical for large-scale hydroelectric dams, involving turbines and generators driven by water flow. The environmental significance of Big Bend Dam lies in its role as a renewable energy source, producing electricity with low direct carbon emissions compared to fossil fuel plants. However, hydroelectric dams can affect local aquatic ecosystems and river flow regimes. The facility serves the regional grid, providing reliable baseload power and supporting grid stability. Its operational context includes managing water levels and flows for both power generation and other purposes such as flood control and irrigation.

As a hydroelectric plant, Big Bend Dam generates electricity with minimal direct greenhouse gas emissions, supporting climate goals. However, the dam's reservoir can alter local aquatic habitats and sediment transport. The facility's location in the Missouri River basin involves considerations for fish passage and water quality, managed under federal environmental regulations. The plant's capacity of 538.3 MW places it in the large-scale category for hydroelectric power, with corresponding environmental oversight.
