Abstract

This work presents a case study of a distributed microgeneration project, 75 kWh inverter in a client served directly in Tariff Group A, involving the production of energy to supply the consumption of its Factory in order to reduce its energy costs. electrical. Together with the project and its sizing, we studied the financial return from removing contracted demand from this client, placing it in Tariff Group B in the special situation known as Opting B Finally, the study of economic goals was carried out using important financial analysis tools, namely payback (return time on investment), profitability rate, IRR (internal rate of return) and NPV (net present value). In this study we investigated with two analyzes to evaluate the financial return, we studied the customer with Solar Energy remaining in Group A and paying contracted demand and we studied the customer adapting to Option B and not paying demand, after that we practically showed the monthly savings which was provided with the installation of the Plant. It is possible to verify that in all economic analyses, the forecast financial aspect of the project becomes more attractive to the consumer in Group B.
