Overview
Alder is a 50 MW hydroelectric power plant located in Washington, United States. Operated by the City of Tacoma, it contributes to the region's renewable energy generation.
Alder is a hydroelectric power plant with a capacity of 50 megawatts, situated in Washington State, United States. The facility is owned and operated by the City of Tacoma, serving as a key component of the local renewable energy infrastructure. Hydroelectric power plants like Alder harness the energy of flowing water to generate electricity, providing a clean and sustainable energy source. The plant operates under the regulatory framework of the United States, including the Clean Air Act and state-level environmental regulations. Hydroelectric facilities are generally considered low-emission, but they must comply with water quality and ecosystem protection standards. The 50 MW capacity places Alder in the small-to-medium scale range for hydroelectric plants in the US. Alder plays a significant role in Tacoma's energy portfolio, supporting the city's commitment to renewable energy and reducing reliance on fossil fuels. The plant's operation contributes to grid stability and provides clean electricity to the local community, aligning with broader state and national goals for sustainable power generation.
Environmental context
Hydroelectric power generation has a low carbon footprint compared to fossil fuel plants, but it can affect local aquatic ecosystems and water flow regimes. The Alder plant is located in a region with significant rainfall and mountainous terrain, which supports consistent water availability for power generation. Proximity to populated areas is moderate, and the facility's age and technology are typical for a mid-20th century hydro project, with ongoing maintenance to ensure efficiency and environmental compliance.
