Avangrid starts laying panels on another large solar project in Oregon

July 8, 2026 · Solar Power World · Score: 18

Avangrid has started installing solar panels at Oregon Trail Solar, a 57-megawatt project in Gilliam County, Oregon. This is a large utility-scale solar farm, not a rooftop system, and it's separate from any home solar programs. When finished next year, the project will have more than 100,000 panels and generate enough electricity to power about 10,000 U.S. homes annually.

The project is expected to bring $6 million over its lifetime to Gilliam County through a mix of property taxes and PILOTs (payments made in place of taxes), money that goes toward schools and other local services. Construction is also supporting 200 union jobs. Oregon Trail sits next to Avangrid's existing Pachwáywit Fields solar project and its newly announced Shutler battery storage project, adding to a growing cluster of energy infrastructure in the area.

For homeowners, this doesn't come with any rebate or program you'd apply for. It matters mainly as a sign of how much new electricity supply is being built in Oregon. Avangrid now operates more than 2.5 gigawatts of capacity in the state, including other recent solar farms in Wasco and Morrow counties. More local power generation like this can affect the region's electricity supply and grid reliability over time, but it doesn't change what's available to you as a homeowner looking into rooftop solar, heat pumps, or other efficiency upgrades for your own house.
