​Hydropower’s reliability, flexibility supports other renewables

The rivers of the northwest are not only icons of the region’s natural beauty, but also a constant supply of energy. Rain and snow feed the water cycle, providing a renewable resource to meet the energy demands of millions while seamlessly integrating other renewables such as wind and solar. 

Just as the river is always flowing, hydroelectric dams have the ability to constantly generate electricity. Hydroelectric generators can respond to increased power demands at any time of the day or night, and in any given weather condition regardless of wind or sunshine.

Because hydroelectric dams can dispatch power to the grid instantly, they provide essential back-up power during major electricity disruptions. Hydropower is also unique among energy sources in its ability to resume operations without needing to draw power from another source.
