In this study, technical and economic analysis of Organic Rankine Cycle (ORC) systems in Turkey and their application areas have been examined in detail. Also, the government incentives for renewable energy productions and industrial waste heat recovery opportunities are investigated and presented. ORC technologies have been dealt with individually in geothermal, solar, biomass and industrial waste heat based power generation plants. In this concept, some power plants have been selected for each application and the technical specifications of these examinations have been presented. An application in a biomass based plant, which has 1 MW of installed capacity, has been given as an example. According to the feasibility analysis, the investment payback period of this ORC application has been calculated as 2.7 years and the results have been presented and commented. (C) 2016 Elsevier Ltd.
