Tacoma Power was established in 1893 when the residents 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.

Today, Tacoma Power, a division of Tacoma Public Utilities, is a community-owned, not-for-profit energy provider. For over a century, our City of Tacoma and Pierce County customers have depended on us for safe and reliable energy.

Our clean energy future will be built on a solid foundation of renewable, carbon-free hydropower, while we expand to include innovative energy technologies.

We commit to continuing to make thoughtful and responsible choices about our financial and environmental resources.
