Seattle City Light is the public utility providing electricity to Seattle, Washington, in the United States, and parts of its metropolitan area, including all of Shoreline, nearly all of Lake Forest Park, and parts of unincorporated King County, Burien, Normandy Park, SeaTac, Renton, and Tukwila. Seattle City Light is the 10th largest public utility in the United States and the first municipal utility in the US to own and operate a hydroelectric facility. In 2005, it became the first electric utility in the United States to fully offset all its carbon emissions and has remained carbon neutral every year since.

James Delmage Ross was the superintendent of lighting for Seattle for 28 years and was the first administrator of the Bonneville Power Administration. He was instrumental in developing the Cedar Falls and Skagit River hydroelectric power plants. A self-taught engineer, Ross advocated for public utilities and regional power networks. He also later served as a member of the Securities and Exchange Commission.
