The nation’s first solar highway installation is up and running in Tualatin. The solar photovoltaic demonstration project is a collaboration between Portland General Electric, US Bank and the Oregon Department of Transportation.

The $1.3 million project helps light the Interstate 5 and Interstate 205 interchange in Tualatin. The project also provides PGE with data on how well such a generation site can perform in its service area.

The 104-kilowatt solar photovoltaic system covers about 8,000 square feet and is about the length of two football fields.

It is producing about 112,000 kilowatt hours a year, or 28 percent of the 400,000 kilowatt hours used to light the interchange.

The solar panels produce electricity during the day, supplying power onto the PGE grid, and PGE returns an equivalent amount of power at night to light the interchange.

SolarWorld AG of Hillsboro supplied the solar panels, and PV Powered of Bend supplied the inverter that converts the solar power for use on PGE’s grid.
