Payment Plans & Bill Assistance

Seattle City Light is disconnecting customers for non-payment. City Light has flexible payment plans available to all customers. For income-eligible residential customers, we have bill assistance programs available, including emergency bill assistance and the Utility Discount Program. If your electricity has been disconnected, call (206) 684-3000 Monday – Friday 7:30 am – 6:00 pm to discuss your options.

Power Supply and Delivery

Most of the electricity we provide to customers comes from several utility-owned hydroelectric resources located in the Pacific Northwest. To make up the difference, we purchase any additional power needed from other energy providers.

To maintain our carbon-neutral status, we purchase Renewable Energy Credits (RECs) to offset carbon from energy purchased from other providers. We also invest in energy conservation that minimizes electricity demand.

How Your Energy Gets to Your Home or Business
