About Tacoma Power 1

Tacoma Power is a proud member of the National Hydropower Association

Tacoma Power was established in 1893 when the citizens of Tacoma voted to buy the privately owned Tacoma Light & Water Company. Local citizens believed that public ownership and local control would give them a higher caliber of services and the ability to maintain control over them. That decision paved the way for us to build one of the finest and most reliable electric systems in the United States.
