The US Department of Energy, Morgantown Energy Technology Center (METC) and Doyon, Limited, a regional Alaska Native Corporation have developed a conceptual design for a coal-fired 500 kWe fluidized bed combustion (FBC) power plant for use in rural Alaskan villages. The focus of this effort is to conceptualize a highly reliable, and modular FBC power plant for the cogeneration of electricity and process heat. The facility will co-fire coal, limestone and solid municipal waste and replace the present diesel oil-fired system. To ensure site conditions would model those found in Alaska, the town of McGrath, Alaska, in the Doyon region of the upper Kuskokwim river valley was selected as a potential plant site. McGrath, like many remote Alaskan villages, is dependent upon costly oil-fired diesel power generation and annual subsidy payment from the State of alaska, through the Power Cost Equalization Program (PCE), to provide village residents with affordable electricity. In the near future rural village utilities will be faced with increased cost of electricity due to transportation, handling, and storage costs of diesel fuel and reduction of funds from the PCE. Economic data from this Doyon/METC study will help justify the use of local or regional coal reserves as a means for reducing the cost of electricity in Alaska`s rural villages. The concept developed for Alaska should be applicable in many third world regions. This paper describes the project definition plant design for McGrath, Alaska, and the costs associated with construction and operation in a remote environment.
