Nowdays the demand of electrical energy is rapidly increasing every year due to the growth of technology itself. Making a power plant is one of the solution but its only causing another problem if the power plant using a fossil fuel to generate the electrical energy. So base on the case that only a renewable energy which can become the fuel to generate the electrical power. Waste to Energy power plant (later is mentioned as WTE) become a solution to solve that problem, one of methods is by using incineration technology. By using waste especially municipal waste the power plant is not only solving the energy demand problem but also decreasing the greenhouse emission produced by a municipal waste which occur if waste is just dumped in a place. The purposes of this research are to analyzed the waste power plant financial visibilty that had been designed before, how much cost to treat greenhouse gases which produced by the WTE, and which scenario of fuel combination that more profitable and consumed more municipal waste. There are several criteria for waste as WTE fuel, which are related to calorific value, moisture value, ash fraction, and combustible material fraction. To fulfill those requirements, cocombustion (mixing with coal) and fuel drying are applied. There are seven types of fuel which are analyzed in previous research. By calculating calorific value, results of proximate analysis, ultimate analysis, and combustion temperature, so the fuel consumption (to generate electricity) from usage of each fuel type is obtained. Fuel type A has fuel consumption value 11.45 tonnes/MWh, type B 3.56 tonnes/MWh, type C 3.13 tonnes/MWh, type D 5.17 tonnes/MWh, type E 3.45 tonnes/MWh, type F 7.27 tonnes/MWh, and type G 3.46 tonnes/MWh. But based on the analysis that has been done type A, B, D, F fuels do not meet the humidity criteria where the humidity of the fuel should be above 50%. Of the three fuel scenarios that meet the criteria. Type C fuel has a loss of -Rp 11,693,931,759/year so that type C fuel is not feasible to continue as fuel. Type E and G fuels meet the criteria and generate profit and after an NPV calculation, an NPV type E of Rp 1,221,401,729,255 with an IRR of 40% and a type G NPV of Rp 1,761,076,419,424 with an IRR of 53%. While in terms of reducing carbon emissions type E reduces emissions by 31.24% compared to PLTU and type G by 43.67% compared to PLTU.
