Possibilities of Reducing Energy Costs by Using CHP Systems in Urban Area of Sarajevo Region

Abstract

Rational use and efficient energy production was not enough introduced in the prewar period and what is the most important, the relevant Governmental departments did not do anything to establish that as an obligation for large consumers. It was one of the reasons why the price of any product and service, because of high participation of energy in the costs, was very high and not competitive in the market. After the war in Bosnia and Herzegovina the situation has changed. To be competitive in manufacturing and servicing, a lot of companies and institutions started to count, more seriously, not to save energy, but to reduce the costs of energy production and to use it rationally. One of possible and perhaps the most attractive way of rational energy production and usage, without large investment and as very quick application, is small scale CHP system (Combined Heat and Power production system). This paper deals with CHP systems implementation within the Sarajevo region and with the presentation of benefits of their using in accordance with: more efficient fuel consumption relating in reducing the costs of any production or service and consequently, making them competitive, because of decreasing of energy participation in them. Three characteristic projects are included, showing the benefits expected from their implementation. Those projects are: Gas Mixing Plant for peak shaving in Gas Consumption, Application of CHP Systems on Existing and new gas generators in City Bakery, City and State Hospital and Central Heating System and as the most interesting using for Sanitary Landfill Gas in Sarajevo Sanitary Landfill. For all the mentioned projects, this paper presents some details which would be useful as an idea for application on the similar systems in underdeveloped countries. The main point presented in the paper is techno-economical background of the projects and their influence on the global energy system of the users.
