Natural gas is furnished by privately owned Puget Sound Energy, which began its existence in 1886, generating electric power as the Seattle Electric Light Company.
An increased amount of BPA power and a 20-year wind contract from the Stateline Wind project are among City Light's new resources. The table below provides information on the fuels used to generate the electricity Seattle City Light provided to its customers in 2013.While Seattle owns no nuclear or coal generation, a portion of the power we purchase from BPA comes from these sources and is reflected in our fuel mix.he remainder comes from a mix of power sources, including long-term contracts with the Bonneville Power Administration (BPA) and others. Since 2001, City Light increased and diversified its resource mix to minimize future dependence on market purchases to meet Seattle's needs.
