Considering the increase in national electricity demand by an average of 6% per year, especially for areas outside of Java that are far from the electricity grid, to meet the electricity needs generally use expensive Diesel Power Plants or small-scale steam power plants with low efficiency. On the other hand, outside of Java has the potential of abundant biomass and waste, which includes biomass from forest waste, plantations of more than 100,000,000 tons used as electrical energy will obtain greater than 1,000Mwe. The potential of this electrical energy will be able to support national energy supply especially in outside Java regions. while at present the performance of conventional steam power plant-small capacity below 5 Mw which has been installed. At this time the efficiency is still low at around 20%. So, we need an electric biomass fuel technology power plant that has better performance. In this analysis, it is proposed that an alternative solution is to use an Organic Rankine cycle-ORC power plant that uses organic working fluids that have lower evaporation temperatures than water. By using this ORC plant that uses n-Pentane as its organic working fluid, it is estimated that the efficiency can be greater than 25%, and environmentally more friendly.
