Tilikum Crossing Vertical-Axis Wind Turbines

The design plans for the Portland-Milwaukie Tilikum Crossing Light Rail incorporated stand-alone vertical-axis wind energy turbine (VAWT) systems at the west and east approaches. A VAWT’s main rotor shaft is set transverse to the wind while the control components are located at the base of the turbine. Because the arrangement allows the generator and gearbox to be located close to the ground, service and repair can be easily managed. Elcon completed the design of the wind system, prepared a construction cost estimate, and outlined the Wind Energy Specification Section of the invitation to bid (ITB) for the installation of the wind energy equipment. ​​​​​​​
