ABSTRACT
To reach the long-term goals of Energy Politics of Latvia, as EU member country, it is solved to use the potential of cogeneration with common heating load about 300 MWth in Latvian big cities and 100 MWth in other Latvian cities until 2016, as well as to stimulate the development of CHP plants using renewable sources of energy (RES) [1]. One of the most important advantages of CHP is a possibility of usage of different local energy resources for energy producing. Latvia has a characteristic centralized power supply system, which means inhabited areas have sufficiently high heat loads to accommodate installation of an efficient cogeneration facility. Sustainable Energy Community Model [2] adopted for Latvian circumstances allows to analyze all types of energy resources and other factors of examined region, to work out the plan of region's energy development (both short-term (2-3 years) and long-term (till 2020)) and management of its realization. SEB model applying includes deep examination of local renewable energy sources, especially the analysis of biomass receiving potential and biomass production possibility. While units of woodchips production are situated in all Latvian territory with quite regular intervals and good system of roads can provide the delivery of wood fuel to all Latvian regions, biomass is a fuel which needs to be used possibly closer to the place of its producing. Potential of biomass production depends on fertility of the earth, which considerably varies in different regions, therefore costs of biomass receiving are different as well. Costs of fuel component (gas produced of biomass) necessary for establishment of CHP plant can be designated as Ibm: where: Ibm= IΣ - Ist IΣ - total costs of CHP plant (including producing of biogas); Ist - costs of plant technological equipment. Ibm - includes the full volume of agricultural works (sowing and harvesting, amortization of agricultural machinery, etc.) The lower is the fertility of earth, the bigger area of earth is necessary for cultivation of biomass. Costs of earth processing can be accepted equal in different regions, though in fact in less fertile regions these costs can be higher, because of processing problems resulting with higher consumption of fuel and more expenses on machinery amortization. There is observed practical example of calculation of biomass costs for CHP plant. The costs of biomass producing make the big part of the total costs of fuel for CHP plant and price of produced energy [3]. In the example there were calculated the costs of biomass producing in fertile region and in region with 50% less fertile earth. The costs of biomass in less fertile region are 42% higher in comparison with costs of biomass cultivated in fertile earth. Accepting that there is no big difference between chosen technologies of CHP plants (from the point of efficiency), choice of fuel can change because of difference of biomass costs. The research demonstrates the meaning of regional factor while estimating possibilities of biomass usage in CHP plants.
