  • ACWA Energy Independence Project — Prepared by Kennedy/Jenks Consultants. This report uses two Oregon treatment plants, Gresham and Corvallis, to show how best-in-class energy conservation and renewable energy sources can make wastewater utilities energy independent. 7/2008.
  • Barriers to Biogas Use for Renewable Energy—Water environment research Foundation – Not all wastewater treatment plants with anaerobic digestion beneficially use their biogas beyond process heating. Knowing this, there must be actual or perceived barriers to broader use of biogas to produce combined heat and power (CHP). This study documented these barriers so that actions can be taken to reduce or remove the barriers that promote energy recovery using proven technology – anaerobic digestion with combined heat and power generation. Includes case studies and biogas fact-sheet and other material. 2012.
  • Underground Injection Wells for Stormwater—Best Management Practices Manual, prepared by URS Corporation – This report, prepared for ODOE by TetraTech, examines possible biogas use as a transportation fuel and to inject into existing natural gas pipelines. Four treatment plant scenarios are examined (Portland-Columbia Blvd., Gresham, Salem, Clackamas County/Tri-City). Useful information about items to consider when evaluating a biogas utilization project. Oregon Department of Energy/TetraTech, 3/20/12
  • Database of State Incentives for Renewables and Efficiency – (DSIRE) funded by the U.S. Department of Energy. DSIRE is a comprehensive source of information on state, local, utility and federal incentives and policies that promote renewable energy and energy efficiency. Established in 1995 and funded by the U.S. Department of Energy, DSIRE is an ongoing project of the N.C. Solar Center and the Interstate Renewable Energy Council.
  • No Cost Energy Trust Audit – Learn how to get a no-cost energy audit for your wastewater facility.
  • Energy Efficiency RFP Guidance for Water-Wastewater Facilities – The Energy Efficiency RFP Guidance for Water-Wastewater Facilities (The Guidance) is an informational resource for water and wastewater utilities seeking to improve the energy performance of their facilities through an upgrade, expansion or new construction project. The Guidance discusses key components of an energy efficiency RFQ or RFP and provides focused recommendations for particular energy-intensive equipment and processes. It also includes sample language, which RFP writers may, if appropriate, transfer directly to their own solicitations. Consortium for Energy Efficiency/WERF, 2010.
  • FOG Market and Evaluation Reports Medford • Gresham Fog Feasibility Study • Salem Fog Market Evaluation – A variety of wastewater treatment plants are completing reports on the market availability of Fats, Oil and Grease (FOG). Sharing these reports may be useful to treatment plants considering installing FOG receiving facilities. PDF
  • Growing Oregon’s Biogas Industry, Feb 2011 (PDF). The Climate Trust/Energy Trust of Oregon. Biogas, a renewable substitute for natural gas, is generated by breaking down organic waste in an anaerobic digester. Oregon’s dairies, wastewater treatment plants, municipal solid waste collectors and food processors have the feeds to ck and infrastructure to generate over 100 megawatts (MW) of biogas energy, but currently, have only 8 MW installed. Dairy farms have the greatest potential to generate biogas energy and wastewater treatments plants currently generate the most biogas energy.
  • O&M Energy Efficiency Checklist for Wastewater Treatment Plants – Key elements to examine when looking for areas to improve treatment plant efficiency in order to reduce energy costs. 5/9/2012
  • Renewable Energy Cost Calculations – Use these Excel spreadsheets to calculate costs for installation of priority renewable energy systems at wastewater treatment plants. More about the spreadsheets and the background information is included in the ACWA Energy Independence Report.
