Renewable Energy Credits

As a City Light customer, you are already receiving about 90% carbon-free electricity. We also track and offset any remaining carbon from our fuel mix and operations, meaning City Light and the electricity you use every day have a net-zero impact. The Pacific Northwest region, however, continues to rely on fossil fuels for much of its energy and our Green Up program gives you the opportunity to support the growth of renewable energy in our region and right here in our community.

Green Up is a voluntary renewable energy program that allows you to support Pacific Northwest wind, solar and other renewable energy projects generating carbon-free energy. When you enroll in Green Up, we purchase regional renewable energy credits (RECs) on your behalf and fund local rooftop solar projects hosted by not-for-profits and public organizations like affordable housing, schools, and parks.

Why Join Green Up?

  • It's a low-cost way to support clean energy: You choose your support level - starting as low as $1 a month per 100kWh block to matching 100% of your electricity use or more!
  • It's a green thing you can do to help protect the environment: By supporting this program, you are adding clean, renewable energy to the regional and local power grid
  • It's innovative and equitable: Green Up is increasing access to clean energy and green jobs, improving the health and economy of our local communities and the region

How Does Green Up Work?

  • You buy renewable energy credits through Green Up - there are two ways to participate and the cost is added to your regular City Light bill
  • City Light purchases Renewable Energy Credits (RECs) from local and regional projects on your behalf - one renewable energy credit for every 1,000 kWh of electricity they produce
  • You can cancel at any time - there are no long-term commitments or additional fees
  • Green Up is certified by the Green-e(R) Energy Program which guarantees the program meets strict environmental and consumer protection standards established by the nonprofit Center for Resource Solutions
  • Green Up charges will show up on your electricity bill, either at a match level of your choosing or a set monthly dollar amount (Green Up purchases are not tax-deductible. Since it is a purchase, it is not considered a charitable donation)
  • The renewable energy credits purchased through Green Up are generated from Green-e approved wind, solar, or other renewable sources. Learn more about Green Up renewable resources.

Two Ways to Participate

Green Up Match is one of the easiest ways to contribute to a clean energy future for our region. Match up to 100% of your monthly electricity use, or a percentage of your choosing. The average City Light home uses about 600 kWh of electricity each month. A 100% Green Up Match of the average home would equal a $6 monthly commitment or $12 on a bi-monthly bill. 

Sign up for Green Up Match and select the level of your choice. 

You don't have to spend a lot of money to contribute to a clean energy future for our region. For as little as $1 a month you can purchase a 100 kWh Green Up Block to be added to your regular City Light bill. There are no limits to the number of Green Up Blocks you can purchase. The more you purchase, the more renewable energy you support.

Sign up for Green Up Blocks and choose your monthly dollar amount contribution.
