Oregon Launching First Solar Highway in the US


Oregon is once again taking the lead with renewable energy by installing the country’s first highway solar energy project. The project will consist of a 104 kW solar photovoltaic system that covers 8,000 square feet and produces 112,000 kWh each year. That’s 28% of the energy needed to power the project’s location, the Interstate 5 and Interstate 205 interchange in Tualatin.

Electricity for the interchange will be provided by PGE. The solar panels will come into play by producing electricity during the day, giving the power to the PGE grid, and getting the equivalent amount of power back at night from PGE to power lighting on the highway.

The whole project will literally be Oregon-powered, as companies based in-state will provide materials, design, and installation.

Next year, the Oregon Department of Transportation plans to look at more highway project proposals. Eventually, the department would like to generate 2 million kWh every year with the new projects. They also are looking for proposals that showcase new ways to utilize solar energy, such as solar panels that double as sound walls near highways.

So if you happen to have any good ideas on Oregon solar, get in touch with ODOT— they’re clearly open to progress.
