RATIONAL USE OF ENERGY IN THE UKRAINE - A PILOT-STUDY FOR DESNA

Significant price increases of gas and oil and the deterioration of th e ecological situation in the Ukraine require a fundamental transforma tion of the Ukrainian energy system towards increased energy efficienc y and less risky energy-conversion technologies. For DESNA, the larges t military housing facility in the country, a detailed set of energy d emand and supply data has been compiled. Based on these, a number of e nergy conservation strategies and the associated savings in energy cos t and CO2 emissions have been analyzed with the latest, easy-to-use ve rsion of the stochastic optimization model ECCO in a pilot study which serves as a precursor to broader investigations for the region of Kie v. Depending upon the scenario, optimization indicates saving potentia ls between 15 and 50% of the primary energy input of the present DESNA energy system. The corresponding reductions of energy cost and CO2 em issions range from 28 to 65% and from 2 to 38%, respectively. Combinat ion of these results with investment and maintenance costs, which are difficult to estimate in the present situation of economic transition in the Ukraine, should allow the choice of the technology option which is fitted best to the Ukrainian economic and environmental constraint s.
