In rural Alaska, there are about 200 villages, which have independent diesel power plants. Their power capacities range from tens of kW to multi-MW. In 2007, the total diesel electrical power usage of rural Alaskan villages was about 370,000 MW-h. According to literature, no villages have applied exhaust heat energy, which is about the same magnitude of the electrical energy consumed, for any useful applications. In order to find the villages, which are feasible for exhaust heat recovery applications, to improve their energy economy and reduce green house gas (GHG) production as soon as possible, a methodology which is reliable and inexpensive and can be easily used for preliminary identification of those villages is desirable. Due to the uniqueness of each village in power load, heating load, power system infrastructure, heating system infrastructure, technical personnel availability, labor cost, shipping cost, etc., the desired methodology needs to take all these factors into consideration. In addition, the exhaust heat recovery system design and analysis method, which is an inherit part of this application; need also be addressed in the methodology development.
