Thinking of a renewable energy project in your community?

 
The Community Renewable Energy Feasibility Fund, or CREFF, is a grants program that funds feasibility studies for renewable energy, heat, and fuel projects in Oregon.

The fund is administered by the Oregon Department of Energy with two goals:
  • Encourage widespread adoption of renewable energy projects that reduce Oregon’s dependence on fossil-based energy sources
  • Promote sustainable economic development within the state
To support these twin goals, the Department of Energy has published studies below that investigate renewable energy development in Oregon. By making these studies publicly available, the State of Oregon helps future renewable energy developers learn the lessons of past work and think critically about how to structure their own feasibility study.
 
Please contact the CREFF Coordinator for more information on any of these studies.

Title Year Author Region Sector Abstract
Baker School District Biomass Heating Feasibility Assessment 2010 CTA Architects Northeast Biomass
 
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.

Blue Mountain Lumber Products Biomass Power Feasibility Study ​2011 ​The Beck Group ​Northeast ​Biomass ​This study evaluates the feasibility of a biomass fueled cogeneration plant at Blue Mountain Lumber Products’ (BMLP) operation. Blue Mountain Lumber Products (BMLP) is a family-owned, fully integrated forest products company located in Pendleton, Oregon that produces 24 million board feet of commodity lumber, specialty lumber, and timbers annually, as well as 20,000 tons of wood fuel pellets annually.
Ochoco Lumber Company: Steam and Heating System Improvement Project ​2011 ​The Beck Group ​Northeast ​Biomass ​Malheur Lumber Company (MLC), a sawmill located in John Day, recently installed new equipment that can convert mill residues (e.g., sawdust) into wood pellets and wood briquettes, which are then sold as a heating fuel. In addition, MLC is in the process of installing other equipment that is capable of converting small diameter logs into wood shavings, which will then be bagged and sold as animal bedding. The combination of steam needs for lumber drying, fiber drying, and other miscellaneous small heat loads has the potential to exceed the capacity of the boilers.  Therefore, the objectives of this study are to: (1) Quantify what the potential steam shortage might be and when it might occur. (2) Identify a range of possible solutions that will minimize the shortage. (3) Identify the costs (if any) associated with implementing the identified solutions.
