The 5.7 megawatt solar array, known as Outback, that last year started sprouting up along the landscape in southeast Oregon's Lake County is finished and is generating power.  The solar power plant is made up of 20,000 ground-mounted photovoltaic panels and is expected to generate approximately 10 million kilowatt-hours of electricity per year.

The project was developed by Obsidian Finance Group and Smart Energy Capital and helped along by $15 million in incentives from the state's Business Energy Tax Credit program and a grant from the Energy Trust of Oregon.

Constellation Energy, a subsidiary of Chicago-based Exelon Corp., financed and owns the array, having acquired it last October. Portland General Electric will purchase the power generated by the plant through a 25-year power purchase agreement. Through its PPA with Constellation, PGE did not have to commit upfront capital to build the project and retains the environmental attributes of the project to meet the state of Oregon’s renewable portfolio standard requirements.
