Portland General Electric and its partners have rolled out the largest solar project in the Pacific Northwest, which is expected to begin producing up to 1.1 MW of electricity for PGE customers by December.

The project, using “thin-film” solar panels, is being installed on the rooftops of three ProLogis distribution warehouses in northeast Portland. The solar panels will cover more than 328,000 square feet.

“To meet Oregon’s future energy needs, we’re going to need every tool in our tool box,” said Peggy Fowler, CEO and president of PGE. “With this project, we will be putting solar power directly onto the grid, adding to the renewable energy PGE already is delivering to our customers.”

PGE already supports customer-owned solar power projects through net-metering arrangements, which allow customers to generate their own solar power and tap into the PGE grid as needed. In addition, part of PGE’s contribution comes from funds—provided by the company’s Clean Wind renewable power customers—that support renewable power demonstration projects and development of renewable power resources.

Fowler thanked U.S. Bank, ProLogis, Energy Trust of Oregon, United Fund Advisors and Solar Integrated Technologies for working with PGE to make the project possible.
