Avangrid Finishes 120-MW Oregon Solar, Connects Grid

• Avangrid completes Oregon’s Morrow County Tower Solar—120 MWac, 166 MWdc—now grid-connected. Powering thousands of homes, boosting Iberdrola’s renewables, and cutting emissions across the western U.S.

Avangrid Inc says it has finished construction of a Tower Solar project in Oregon’s Morrow County, a 120-MWac facility with 166-MWdc capacity. The company also reports the plant is now connected to the regional power grid, marking the project’s transition to operations.

The utility, which is part of Spain’s Iberdrola Group, said the project will add to its renewable energy portfolio and help expand clean power across the western United States. Avangrid expects the output to supply electricity for thousands of homes and support emissions reductions and regional energy diversification, as utility-scale solar investment continues growing nationwide.

What does Avangrid’s 120-MWac Oregon Tower Solar project add to the grid?

• Adds 120 MWac of utility-scale solar generation to Oregon’s power supply, increasing available renewable capacity connected to the regional transmission network
  
• Introduces about 166 MWdc of solar PV capacity, supporting the grid with more total array output while converting to an ac grid feed-in of 120 MW
  
• Improves generation diversity in the western U.S. energy mix by increasing the share of daytime renewable power alongside wind, hydro, and other resources
  
• Can help meet electricity demand during sunny periods, which often correspond to midday load and can reduce reliance on fossil generation at those times
  
• Provides additional clean-energy output that can support broader emissions-reduction goals by displacing higher-emitting electricity sources when the plant is operating
  
• Strengthens long-term grid planning by expanding firm operational generation assets under utility oversight once the facility begins regular production
• Supports energy resilience by adding another geographically distinct, utility-scale renewable resource within the region’s generation portfolio
