Abstract: The aim of this study is to investigate the potential use of natural gas for heat and power production for the municipality of Linköping, Norrköping and Finspång in the County of Östergötland, Sweden. The results of the study revealed that these three municipalities with the present heating demand can convert 2030Â GWh/year of the present fuel mixed to natural gas. The expansion of natural gas provides the possibility to increase the electricity generation with approximately 800Â GWh annually in the County of Östergötland. The global emissions of CO2 reduce also by approximately 490Â ktonne/year by assuming the coal condensing power plant as the marginal power plant. The total system cost decreases by 76Â Mkr/year with the present electricity price which varies between 432 and 173Â SEK/MWh and with 248Â Mkr/year if the present electricity price increases to 37% which is approximately corresponding to European electricity prices. Sensitivity analysis is done with respect to the different factors such as price of electricity, natural gas, etc. The findings show that increased price of electricity and increased district heating demand increases the profitability to convert to natural gas using CHP plant.
