Water Cycle: The power behind the hydropower
Hydropower is reliable and renewable, thanks to the benefits and predictability of our planet’s water cycle.
Clean Energy: The Northwest way of life
The electricity in the Northwest is among the cleanest in the nation and we have our region’s rivers to thank.
Power Generation: From water to watt
As water flows through a dam, the pressure of that falling water turns a large turbine and makes electricity.
Transmission: From dam to doorstep
Electricity flows along transmission and distribution lines sometimes traveling hundreds of miles.
Snowpack: From powder to power
The water that drives the Northwest’s hydroelectric dams comes from rain and snow further upstream.
Dams: One structure, many benefits
At first glance, dams look like they only hold back and store water, but they actually do so much more.
Reliable Energy: Balancing supply and demand
Hydropower is the Northwest’s largest renewable energy source, powering the region day or night, rain or shine.
Reservoirs: The region's storage battery
Like giant storage batteries, reservoirs behind dams can hold back water to meet future energy needs.
Integrating Renewables: The perfect partner
The perpetual nature of hydropower makes it the perfect partner to variable renewables like wind and solar.
Resource Adequacy: Meeting the region's energy needs
Enough energy must be available to meet electricity demands under both normal and extreme conditions.
