45 years of preservation – Powerlines


For 45 years, Seattle City Light has had the longest running conservation program in the country. Since its inception in 1977, utility-supported energy efficiency measures have been installed in residential, commercial and industrial facilities throughout our service territory. Through these legacy and current programs, City Light’s annual load has been reduced by over ~1,224,000 megawatt hours, which is equivalent to the annual electricity consumption of over ~146,700 average Seattle homes. In 2021, we supported our customers’ projects with more than $12.2 million in energy efficiency incentives. City Light’s suite of energy saving programs has saved customers over $196 million on their energy bills.

Conservation is a win-win solution for our customers and City Light. Helping our customers use less electricity is the most cost-effective way to reduce bills and meet the growing energy needs of our communities. Using our electricity supply more efficiently means we don’t need to acquire additional energy resources to power our region, even if demand increases.

In addition to having the longest running conservation program in the country, City Light is also the first utility in the country to be carbon neutral and achieved it in 2005. This achievement is the result of hydroelectricity generation by City Light for 118 years, beginning with our first installation in Cedar Falls in 1904. Since then, we have expanded our facilities throughout Washington State, from the robust Boundary hydroelectric project in the northeast to the three power-generating dams electricity from the Skagit Hydroelectric Project nestled below the peaks of the North Cascades. National Park. In fact, 86% of the electricity consumed by City Light customers is produced by hydroelectricity.

We are proud of our 45 years of conservation efforts and would like to thank our customers who are committed to conserving and preserving our environment. Let’s continue to hold this commitment together for the next 45 years and beyond.
