Abstract Until the next following decades, energy mixed in Indonesia will be dominated by coal. Many studies assert that biomass can be used as coal substitution but it is not the case in the real world because the cost of biomass is still higher than the coal price. This study proposes the cheaper way of making biomass by using special method of local waste processing unit that has a patented name, TOSS. This kind of biomass, which was invented by STT PLN Jakarta, school of technology, is more economical than other biomass because waste as raw materials is much cheaper than other commonly used biomass like wooden forestry or agroplantations. Many cities in the world are solving their municipal waste problem by using large scale and high tech approach, which process is conducted in the landfill area. TOSS is using small scale and simple technology that can convert waste to become pellet by local people in its source. The pilot project at Klungkung showed that the pellet of TOSS can be used not only for cooking but also for diesel fuel substitution. This study will use that finding to show that TOSS pellet can also reduce coal consumption by mixing it with normal coal. The simulation is conducted by calculating the equivalent energy and capacity of waste energy from TOSS in term of coal equivalent under the context of Indonesia.
