Castle Rock Hydroelectric Power Plant, Wisconsin | USA Renewable Energy Facility

Castle Rock is a hydroelectric power plant located in Wisconsin, United States, with a generating capacity of 15 megawatts (MW). It is owned and operated by Wisconsin River Power Company and is currently operational. As a hydroelectric facility, it contributes to the region's renewable energy portfolio. The plant operates under the regulatory framework of the United States, including the Clean Water Act and Federal Energy Regulatory Commission (FERC) licensing for hydropower projects. Hydroelectric plants like Castle Rock typically use run-of-river or reservoir-based technology to convert water flow into electricity. With a capacity of 15 MW, it is considered a small-scale hydroelectric facility. Castle Rock provides clean, renewable electricity to the local grid, reducing reliance on fossil fuels. Its operation supports Wisconsin's energy mix and helps meet state renewable energy goals. The plant's location on a river also supports local water management and ecosystem services.

As a hydroelectric plant, Castle Rock generates electricity with minimal direct emissions of CO2, SOx, or NOx, offering a low-carbon energy source. However, hydroelectric projects can affect local aquatic ecosystems and water flow regimes. The plant's capacity of 15 MW suggests a relatively small footprint, and its operation in Wisconsin aligns with state policies promoting renewable energy.
