Biomass can be used as an energy source to generate electricity through rankine cycle. However, due to the heat of combustion produced is low, a cycle with an organic working fluid is used in the cycle. This system can be designed to produce small-scale electricity for community needs. This minimalist design is expected to make it easier for people to meet their electricity needs. Conceptual studies are carried out using Aspen plus application and simple economic calculations. The biomass used was palm shells, the heating medium used was Therminol 66, and the working fluid was varied (R21, R114, R141b, R245fa, and R123). Based on the research results, the working fluid that has the highest efficiency in the organic rankine cycle with the same operating condition is R21, which is 13.71%. It takes 90 kg/hour of palm shell to generate 35 kW of electricity per hour. The cost required to design this equipment is 2,020,608,041 IDR.
