Overview
Madison Dam is an 8.8 MW hydroelectric power plant operated by NorthWestern Energy in Montana, United States. It provides renewable energy to the regional grid.
Madison Dam is a hydroelectric power plant located in Montana, United States, with an installed capacity of 8.8 MW. Owned and operated by NorthWestern Energy, the facility is currently operational and contributes to the region's renewable energy portfolio. As a small-scale hydroelectric plant, Madison Dam utilizes the flow of the Madison River to generate electricity. Hydroelectric power is a low-carbon energy source, and plants of this size typically operate with minimal emissions. The facility's technology and capacity are typical for run-of-river hydro projects in the mountainous western United States. The plant plays a role in supporting local energy needs and grid stability. Its operation aligns with state and federal renewable energy goals, and it benefits from regulatory frameworks such as the Clean Water Act and FERC licensing requirements for hydroelectric projects. The facility's environmental footprint is relatively low compared to fossil fuel plants.
Environmental context
Hydroelectric plants like Madison Dam have a low carbon footprint but can affect local aquatic ecosystems. The facility's location on the Madison River may influence fish migration and water flow patterns. Proximity to populated areas is limited, reducing direct human impact. The plant's small capacity minimizes large-scale environmental disruption.
