| Resumo: | The Brazilian brewing sector is broad and ranges from agribusiness to small retailers. With more than 2.2 million employees and a production chain that involves several sectors, the brewing industry is one of the pillars of the Brazilian economy. In the craft beer market, which represents around 2.5% to 2.7% of total production, the high cost of electricity is a challenge for this sector. In view of this, solar energy emerges as a viable solution to reduce electricity costs in the production of beers. Thus, the objective of this work was to dimension a photovoltaic solar plant (UFV) to meet the energy demand of the Raffe craft brewery, as well as to evaluate the economic viability of this investment, analyzing an optimistic scenario and a pessimistic investment scenario, aiming to make production more sustainable and less costly. Data on the brewery's energy demand were collected from the current energy supplier, while solar irradiation data were collected at the Reference Center for Solar and Wind Energy Sérgio de Salvo Brito (CRESESB) and used to size a photovoltaic plant. The economic feasibility analysis was carried out using capital budgeting techniques such as Simple Payback, Discounted Payback, Net Present Value (NPV) and Internal Rate of Return (IRR) as analysis indicators for project acceptance or rejection. The dimensioning carried out generated a plant of 55.34 kwp of nominal power to meet the energy demand of the brewery. The dimensioning carried out proposed a plant of 55.55 kwp of nominal power, with an average generation of 7,054 kwh/month to meet the energy demand of the Raffe brewery. The result calculated for the simple Payback was 4.09 years for the optimistic scenario and 5.52 years for the pessimistic scenario, for the discounted Payback it was 4.37 years for the optimistic scenario and 5.82 years for the pessimistic scenario. The NPV was BRL 1,243,165.91 for the optimistic scenario and BRL 1,188,835.60 for the pessimistic scenario, the IRR for the optimistic scenario was 41.87% and for the pessimistic scenario it was 34.41%. These results demonstrate that the project is economically viable, in the two evaluated scenarios, adopting the guidelines established by capital budgeting techniques. The project also proved to be technically feasible. |
