Constellation completed an aggregate 5.7-MW (DC) solar generation project for Portland General Electric (PGE) in Lake County, Oregon. Constellation financed as well as owns and operates the solar power system. In return, PGE purchases and receives all of the electricity generated by the solar panels at a fixed rate from Constellation under a 25-year solar power purchase agreement (PPA). The solar power system comprises more than 20,000 ground-mounted photovoltaic panels. The project is expected to generate approximately 10 million kWh of electricity per year.
