“The plant consists of a 120,000 pound per hour boiler.”

Project Description

The Heppner Power Plant is a 10 megawatt wood fired power plant that was formerly used as an energy source for a wood products plant. The plant had been mothballed when the facility was closed. When the Port of Morrow acquired the power plant they contracted with PES to refurbish the equipment, replace equipment that had been sold, and restart the plant as an independent power generation plant. The plant consists of a 120,000 pound per hour boiler supplying steam to a General Electric turbine/generator.
