This study compares three energy system setups for supplying the electricity and heat demand in a residential area. Two of the setups contain district heating and a combined heat and power unit. The first setup contains a thermal storage and the second contains an electric battery. The third setup is all electric (incl. the heat production). The second setup reduced the electricity balancing demand the most, but had the highest CO_2,eq-emissions. The third setup had no emissions, but the highest cost. This setup also increased the balancing demand. The first system, with the thermal storage, performed most satisfying when electricity balancing capacity, CO_2,eq-emissions, and costs were weighed together.
