The City of Gresham, Oregon has reached a much-anticipated milestone: its wastewater treatment plant has achieved net-zero status. Through a combination of anaerobic digesters and a CHP unit, the plant now runs entirely on energy that it produces itself. This project was a winner of CESA's 2014 State Leadership in Clean Energy Awards, and is supported by CESA members the Energy Trust of Oregon and the Oregon Department of Energy.
