Hydro
PacifiCorp owns 30 hydropower facilities, located in Washington, Oregon, Idaho, Utah, Montana and California.
With a total generating capacity of 971 megawatts (MW) of electricity, our hydro resources power households and businesses across the West.
The lands and water along these facilities also provide recreational opportunities for visitors to enjoy, and support thriving wildlife habitats.
Hydroelectric facilities
Hydroelectric projects generally operate under licenses issued by the Federal Energy Regulatory Commission (FERC). A hydroelectric license includes terms and conditions for project operations, as well as environmental protection, mitigation and enhancement measures to mitigate project impacts on the surrounding environment and natural resources.
Safety around dams and waterways
We are committed to keeping visitors and the public safe near our facilities and waterways. That's why we share important safety information for visitors to our recreational areas and for contractors working near our hydroelectric facilities.
