The assessment will determine the viability of biomass energy integration at Baker High School in Baker City, Oregon. The summary shows that all the biomass fuel options will have fuel cost savings over natural gas. At the present time, a chip boiler system appears to be the strongest project, especially if at least 50% of the project cost can be offset by a grant.

Lane County received $250,000 from the Field Burning Research Fund for a short-term research project to identify near-term viable options for adding economic value to Annual Ryegrass Straw (ARS) through renewable energy and fuel production. This report explores the financial, technical, and social feasibility of converting ARS into energy as an alternative to the agricultural practice of field burning ARS. Specifically, the research is intended to answer: Is it possible to convert Ryegrass straw into energy as an economic alternative for seed growers to field burning?

A feasibility study was initiated at Volbeda Dairy to determine if digestion is a technically and financially viable option for converting dairy manure to energy at the farm. To that end, EC Oregon assessed dairy manure degradability, reviewed relevant literature, identified locally available additional feedstocks, researched technology options, estimated energy/co-product outputs and system costs and produced pro forma financial analysis.

This report is a four-part feasibility study to analyze the opportunity for an International Wood Fuels (IWF) wood pelleting facility in Baker City, Oregon.

A technical, fiscal, and permitting feasibility study has been conducted for the Coos Bay North Bend Water Board pertaining to the development of hydroelectric facilities at the Upper Pony Creek Reservoir.  A net-metering design for onsite use of the generated power model was selected based on projected power generation rates.  The pro-forma for the project developed to reflect the preliminary build-out design, historical electricity inflation rates, and currently available tax credits and utility incentives projects a return on investment of greater than 15 years.  An alternate operational scenario based on moderate industrial growth flow rates was also investigated.

This report evaluates two potential opportunities for energy recovery projects within the City of Beaverton's water distribution system.  The two systems are (1) the altitude valves supplying the Sexton Mountain Reservoir, and (2) ASR #2.

The City of Klamath Falls is currently generating an average of 42,800 cubic feet of biogas per day at the Spring Street Sewage Treatment Plant (Spring Street).  The study focused on a comparative evaluation of four biogas utilization alternatives, the feasibility of augmenting the biogas supply through the addition of fats, oils, and greases to the digesters, and assessing the available grants and incentives for biogas utilization projects.

The City of Klamath Falls is contemplating the installation of a small power plant to produce power with a protion of their geothermal water resource.  New technology has been developed which may enable the City to convert the thermal energy of their geothermal hot water to electricity.

The Town of Lakeview retained Anderson Engineering & Surveying, Inc. to determine if low temperature geothermal power generation was feasible at the Town’s North Geothermal Production Well. This report reviews alternatives and costs for generating power using the Town’s low temperature geothermal resource.

The goal of the Lane County Food Waste to Energy Feasibility Study is to determine if it is financially feasible to construct and operate a Lane County owned anaerobic digestion facility to process local food waste into energy.

Paisley School was analyzed for fuel saving alternatives that could significantly reduce the energy costs of the oil heating bill for the school of $45,000 for last year.  This analysis included (1) the evaluation, through clean-out drilling, of the existing Paisley geothermal well; (2) evaluating significant energy efficiency; and (3) conversion of the existing heating system to geothermal heat pumps.

A summary of the direct-uses known by the Geo-Heat Center located in Oregon is listed The information contains capacity of direct-use, temperature of the resources, any information known by the author and any webpages links known at the time of this writing for each place.

This package is intended to provide a foundation of background information for persons interested in developing a geothermal greenhouse. The material is divided into ten sections covering issues of crop culture and prices, building and operating a greenhouse, heating system design, listing of vendors, USDA extension offices, trade organizations and periodicals, case studies and bulletin articles on greenhouse operations and several templates for applying for the Farm Bill.

This package of information is intended to provide background information to developers of geothermal aquaculture projects.  The material is divided into eight sections and includes information on market and price information for typical species, aquaculture water quality issues, typical species culture information, pong heat loss calculations, an aquaculture glossary, regional and university aquaculture offices and state aquaculture permit requirements.

The purpose of the study was to investigate the economic viability of producing electricity from biomass in Wallowa County.  The study identifies available biomass sources and quantities, and evaluates technologies that could be used to convert the biomass to saleable energy.

This study evaluates the potential for generating electricity using the excess head available in a proposed seven-mile long water transmission pipeline that would connect the Wicks Water Treatment Plant to the Garrison Street Reservoir Site in the City of the Dalles, Oregon.  The study provides a feasibility determination for developing a micro-hydroelectric project on the City's potable water transmission line and integrating the power output into the N Wasco PUD's electrical distribution system.

This Feasibility Study is for a 900 KW hydroelectric plant project located at C-Drop at the intersection of the A, B, and C Canals. These facilities are part of the irrigation system owned and operated by the Klamath Irrigation District (KID). The report is written to demonstrate the technical and economic basis for the project. 

This project evaluated the opportunity for generating electricity using a small-scale hydropower facility installed at the city's Rock Creek Water Treatment Plant (WTP). The Proposed installation, if implemented will make use of existing raw water pipelines that convey water to the plant. The pipelines deliver water to the plant with more pressure than necessary and this excess pressure can be used to generate electricity. 

The Evergreen/SOAR team was hired by the City of Astoria to complete a preliminary assessment of the wind and hydroelectri resource development opportunity that might exist on its Bear Creek water reservoir and watershed property. The key assignments were to determin (A) the magnitude of resource opportunity that may exist by producing power from the water flowing and wind blowing  on the City property; (B) the cost to develop and sell the power that may be produced; and, (C) to identify any avian or environmental issues tha may prohibit such development. 

This report summarizes wind data collected at a 50m meteorological tower located at a proposed windfarm site, about 10 miles south of Hood River, OR. Long-term wind speed and energy estimates have been made for GE 1.5 MW 77m turbines and Siemens 2.3 MW 93m turbines. 

The scope of this study is two-fold. (1) To review the major transmission systems located in Hood River County. (2) To identify several potential sites for small hydro, biomass, and wind projects in the county that are lcoated close to transmission and have realistic potential for community siting. 

The purpose of this technical memorandum is to evaluate alternatives for installing cogeneration technologies to utilize the available digester gas produced at the facility. 

The analysis in this report is based on a pro forma yearly cash flow model developed to analyze and compare the financial attractiveness (using each project’s revenue requirement as the primary metric) of various community wind ownership structures that have been either contemplated or implemented in the US.
