Siemens is currently installing a Sitras SES Energy Storage Unit with supercapacitor technology on the new TriMet Portland-Milwaukie Light Rail Transit Line.

The southeast Portland Tacoma substation location will house a storage unit that allows for energy created during braking to be stored and then re-used in one of two forms: energy savings or voltage stabilization during peak demand times. TriMet will utilize the system in voltage stabilization mode.

“Siemens is proud to offer grid reliability solutions to make rail investments work even harder for this growing region that is leading the way to provide the most efficient and accessible transportation systems for their citizens," says Thierry Godart, president of Siemens Smart Grid North America.
