Photovoltaic energy cooperatives in distributed generation are organizations formed by a group of people who share a common interest in generating and using clean and renewable energy. They benefit from this instrument, which serves as a sustainable alternative to the traditional centralized generation model. Though this system, individuals who lack the financial or technical means do install a system individually are able to access electricity in a better and affordable way, thereby promoting sustainability, decentralization of energy generation and active community participation. The instrument that allows for a discount on the energy fee (EF), enabling cooperative members to receive a discount on this portion of their energy bill combined with the distribution system usage fee (DSUF). The DSUF does not have an incentive on the discount portion, and the public lighting fee formulates the total price of the energy bill, considering the taxes tied to the EF and DSUF portions. Using SAVEPI® tool, it was possible to calculate rates of return as well as the time it would take to recover the initial investment over the years, using its indicators as a premise and applying the Minimum Attractiveness Rate (MAR), which is the time it take to recover the CAPEX. For a total investment of R$ 350.000,00 of own capital, certain discount percentages were considered concerning the TE value. Within the cooperativism model can work on this segment because of the 14.300 Law, which allows renewable energy sources to produce energy through the cooperative’s transfer. In this work,discounts starting from the base price without taxes, launching at R$ 0,63051 and varying from 8% up to 15% discount on this value were considered. The taxes such as ICMS representing 19%, COFINS with 4,32% and PIS with 0,9375% were not considered to this calculation due to the price that incomes from the generator does not have to pay this taxes. The objective of this work is to analyze scenarios to determine when it is advantageous for a 75 kW power plant to join a cooperative model so that its energy can be used by third parties with monetary revenue tied to the performance of this investment project’s production.
