Heat Recovery Fact Sheet
Diesel generation accounts for 94% of power production in the 181 rural communities that receive Power Cost Equalization assistance. Measures that improve the efficiency of diesel generation offer substantial savings in a wide set of situations. (See the
Alaska Rural Energy Plan
AEA's Alternative Energy and Energy Efficiency program is assisting 16 communities throughout the state in upgrading to high-efficiency diesel generators and automated switchgear and developing systems that supply recovered “waste” heat to community facilities. AEA's construction program routinely incorporates these efficiency measures in new power systems. Diesel efficiency measures funded under AEA's Denali Commission-funded Energy Cost Reduction program are estimated to save $10.2 million, chiefly in diesel fuel costs, over the lives of the projects. Installed cost of the projects totals $5.5 million (53% grant, 47% local share).
AEA is a member of the state and federally-funded
Northwest Combined Heat and Power(CHP) Application Center
, a state and federally supported effort that provides technical assistance for heat recovery, district heating, and waste heat-to-power in Alaska, Idaho, Montana, Oregon and Washington.
With funding from the State of Alaska and United States Environmental Protection Agency the Alaska Center for Energy and Power is evaluating opportunities to utilize commercial equipment to make use of waste heat in diesel generation to make additional power and increase overall generation efficiency. Here is the first report from this study.
