Oregon’s largest solar project now online in Gilliam County

Avangrid, a member of the Iberdrola Group, has achieved commercial operation at its 162-MWAC (205 MWDC) Pachwáywit Fields solar farm (also known as Montague Solar) in Gilliam County, Oregon, becoming the state’s largest solar PV plant. The facility will deliver energy to large customers and municipalities enrolled in Portland General Electric’s (PGE) Green Future Impact program, allowing them to meet their ambitious sustainability and carbon reduction goals.
“This new solar project is proof of Avangrid’s strong commitment to accelerating the energy transition in Oregon and in the U.S.,” said Pedro Azagra, Avangrid CEO. “We are proud to work with PGE to help it meet its ambitious targets to reduce emissions and provide clean, reliable power to its customers.”
Avangrid’s Pachwáywit Fields, which began construction in 2021, spans 1,223 acres. During its construction, the facility created around 300 jobs and brought $1.37 million to the community through local taxes and property lease payments.
Pronounced Patch-Why-Wit, this word means “sun” in the Sahaptin language. The project is located on ceded lands of the Confederated Tribes of the Warm Springs, and the name pays homage to the rich history and stewardship of the Warm Springs and Umatilla Tribes.
