Power station is used in geothermal cogeneration or Combined Heat and Power (CHP) plant to generate electric power and heat from a single process simultaneously. Industrial CHP gains attention due to its sustainability and its nature of carbon footprint reduction. In this regard, CHP is more effective than generating steam or burning fuel on-site, and electricity is imported from the grid. CHP is a combined system which finds applications in several techniques and thermal and fuel systems, and these functionalities can be integrated into prevail-ing building structures. In CHP, the modifications are carried out with respect to the energy and user requirements. In heat recovery mecha-nism of CHP plant, several critical parameters are required. The present research work focuses on heat recovery analysis in geothermal co-generation (CHP) plant, in which the methods to lessen the generated secondary (waste) heat is emphasized by enhancing energy efficiency. Further it also includes passive and active strategies. The recent trends of direct electric conversion devices are more useful, and therefore can be introduced in industrial waste heat recovery applications, which are usually applied in CHP or geothermal cogeneration plants includ-ing paper mills and chemical processing and refinery systems, hotels, hospitals, industries and commercial structures, where constant heat and power requirements exist.

Abstract-While constructing the geothermal cogeneration plant the success of the projects depends upon its financial and market feasibility. A new optimization method is used to estimate financing requirements of investment projects will be presented, as well as a new method to predict the optimal year to sell the investment. A case study is used to illustrate the use of a model to assess the financial feasibility of a geothermal cogeneration plant. The conclusion is that Net Present value , Internal rate of Return and Modified Internal rate of Return should be used to assess financial feasibility of investment projects. In addition to calculating the financial feasibility criteria, assessment models should allow the user to perform sensitivity analysis, scenario analysis, and simulation to analyze risk associated with the investment project. Risk probability matrix is used to obtain the risk priority , which then continued with financial analysis for the feasibility study and also sensitivity analysis. The study shows that the parameter investment value will be increased when treatment is done on risk.Keywords:Financial and market feasibility, Geo thermal cogeneration plant, Environmental Aspects, Sensitivity analysis.
