How Does the Water Power Plant in Spokane Work

The water power plant in Spokane, Washington, is a renewable energy facility that generates electricity by harnessing the power from the Spokane River. The plant is operated by Avista Utilities and is one of only a few hydroelectric facilities in the region. Here is a closer look at how this water power plant works.

Water Collection and Intake Structure

The power plant collects water from the Spokane River through an intake structure located near the falls. The structure is designed to allow water to flow into the turbines while preventing debris from entering the system. Gates are used to control the flow of water into the turbine chambers, optimizing energy production.

Turbines and Generators

The plant features two turbine chambers each with a generator that is driven by the force of the water. The turbines are located underground, and water is directed onto the blades, causing them to spin. The movement of the turbines is transferred to the generators, which then convert the kinetic energy into electrical energy.

Transmission Lines and Power Distribution

From the generator, the power is transmitted through transformers and switch gear to increase the voltage for efficient transmission. The plant’s output is connected to the electrical grid, providing electricity to the surrounding communities. The plant generates approximately 50 megawatts of electricity, enough to power 34,000 homes.

Environmental Considerations

Hydroelectric power is a clean renewable source of energy. The plant in Spokane has measures in place to protect the environment and wildlife in the area. Fish ladders are installed to allow salmon to swim upstream, and there are measures in place to ensure that the water temperature is optimal for the fish. Additionally, the plant has a fish tagging program, which tracks the movements of fish in the river, helping to monitor the health of the ecosystem.

Conclusion

The water power plant in Spokane is a prime example of how hydroelectric power can provide clean, renewable energy to communities. With its efficient generation of electricity from the movement of water, this power plant serves as a sustainable solution for power generation in the region. Through the continued use of hydroelectric power, we can reduce our reliance on non-renewable sources of energy and help protect the environment for future generations.
