Sound Transit light rail trains now running on clean energy

Sound Transit’s Link light rail system is now running on 100 percent carbon-free electricity, making it the first major light rail system in the country to achieve this milestone. The accomplishment is made possible through an agreement with Puget Sound Energy (PSE) to purchase wind energy directly from the utility’s Green Direct program. The agreement with PSE is projected to save more than $390,000 in electricity costs over the 10-year contract while also supporting the creation of local clean energy jobs.

“Innovative projects like PSE’s Green Direct program demonstrate how Washington state continues to be a national leader in the clean energy economy,” said Gov. Jay Inslee. “Puget Sound residents can now travel on Sound Transit’s carbon-free light rail while supporting our local economy and homegrown solutions to solve our global climate crisis.”

“Sound Transit is now at the national forefront of operating carbon-free transit,” said Sound Transit CEO Peter Rogoff. “What’s exciting about this partnership is that we are demonstrating that sustainability leadership can be accomplished by simultaneously lowering costs for taxpayers while maximizing positive impacts to the local economy.”

The Green Direct program supplies renewable energy to customers from the largest wind project in Western Washington, the Skookumchuk Wind Facility. Green Direct provides renewable energy directly to six Link Light Rail accounts that serve the Airport Station and Angle Lake Station. These six accounts alone account for just over 70% of the agency’s greenhouse gas emissions from electricity. Because the rest of the Link system is powered by Seattle City Light, the nation’s first carbon neutral electric utility, all of Link light rail now runs on carbon-free and renewable energy.

The Green Direct program will help Sound Transit advance efforts to meet its sustainability goals and implement sustainability initiatives from the voter-approved Sound Transit 3 ballot measure. The agency said it is committed to reducing greenhouse gas emissions, expanding the use of renewable energy and making all electricity used for operations carbon free by 2030.

Sound Transit is a national leader in transit sustainability and a Platinum level signatory to the American Public Transportation Association’s Sustainability Commitment. Sound Transit values external validation of its sustainability efforts and is a member of The Climate Registry (TCR), the premier organization supporting governments in North America to measure, report and verify their carbon footprints. In advance of executing the Green Direct agreement, the agency secured Climate Registered Silver recognition status from TCR by conducting an external audit of its 2018 light rail greenhouse gas inventory and elements of its carbon-free claims; Sound Transit is currently seeking third-party verification of its entire greenhouse gas inventory to continue to verify claims of carbon-free operations.

In addition to continuing to partner with the Green Direct program, in the coming months Sound Transit will be adding a 100KW solar power installation to the Operations and Maintenance Facility– East. In 2021, the agency will receive additional renewable energy from Phase 2 of the Green Direct Program to power the remainder of its PSE accounts, which will enable Sound Transit to reduce its agency-wide greenhouse gas emissions from electricity by 96%.


  1. So if the trains are running on clean electricity, and the dams are being taken down for fish, and the nuclear is bad, and gas is being demonized and coal is too dirty, and solar is only good for 15 % of the year here and wind power is intermittent and a high failure rate and heavily subsidized. Where is the electricity going to come from, on cold windless days in the northwest? Maybe we should all get our our bikes to produce power..

  2. Really? Wind generators only produce ONE THIRD of their rated power, due to the vagaries of wind. Also, these generators are UGLY, and they absolutely blight our beautiful ridgelines.
    They also despoiled 20,000 acres of land, which is over THIRTY SQUARE MILES. And then there are the millions of birds that will continue to die………….

    Plus every single wind MW must have a backup fossil fuel facility to provide needed power for when the wind does NOT blow.

    So this is progress?
