Increasing demand for renewable energy in Oregon has spurred a proposal to exempt most such projects from compulsory review by a statewide siting panel. Supporters argue it would be less expensive and time-consuming for county governments to review plans for solar arrays and other renewable energy facilities.However, advocates of farmland preservation argue that counties will scrutinize renewable energy projects less rigorously that the Energy Facility Siting Council, which aims to ensure such facilities meet statewide standards.Under House Bill 2329, the threshold for mandatory EFSC review of solar facilities would be increased from 100 to 200 acres of arable farmland and certain wind, geothermal and transmission projects would also be exempt from the statewide process.
