Hydro Power

Our four hydro projects generate about three billion kilowatt hours of clean, renewable hydroelectric energy each year, enough to serve about half of our customers’ power needs.

Hydropower is:
  • Key to cleaner communities: We generate hydroelectric energy with flowing water, a naturally replenishing resource that produces no carbon emissions. This helps keep our air clean and costs low.
  • Key to local job creation: We provide full-time careers, contract/seasonal positions, and internships.
  • Key to a dependable clean energy future: Hydropower is the renewable that enables wind and solar to be integrated onto the power grid.

In addition, Tacoma Power’s projects support major fish and wildlife programs, and provide excellent parks and recreation.
