Portland General Electric announced Monday that a 673,000-square-foot rooftop solar project that spans the roofs of seven ProLogis warehouses in Portland, Gresham and Clackamas is now generating electricity.

The $14 million project, announced in March, is being billed as the Northwest's largest installation and is expected to generate 2.4 megawatts, enough to power about 420 homes.

It's the second rooftop project that PGE has completed in partnership with ProLogis. The total amount of solar energy being generated on ProLogis rooftops is 3.5 megawatts.

PGE now has more than 14.3 megawatts of solar capacity in its resource mix â¿¿ enough to power more than 2,400 homes â¿¿ including the 104-kilowatt solar highway demonstration project with the Oregon Department of Transportation and more than 10.7 megawatts of customer-owned solar energy projects.

Solar energy is part of PGE's energy mix, which the utility expects will reach about 9 percent of total energy capacity this year. Oregon's Renewable Portfolio Standard requires PGE to generate 25 percent from renewable energy sources by the year 2025.

PGE partnered with U.S. Bancorp Community Development Corporation, ProLogis, and several Oregon companies on the project. Northwest Solar Solutions, a division of locally-owned Snyder Roofing and the installer for this project, estimates 60,000 hours of family-wage electrical and roofing work in Oregon were created by the installations.

Energy Trust of Oregon will provide $2.3 million in incentives for the project.
