Análise de viabilidade técnica - financeira da inserção de geração fotovoltaica com armazenamento de energia em uma indústria de movimentação de containeres.

Abstract

This work presents the study on sizing of photovoltaic plants in a container company located in Salvador, Bahia, in addition to presenting the technical and economic analysis considering the estimated costs and the projected technical variables. Through an initial analysis of the location of the installation of the PV plant, the area available, the consumption of electricity, the price of energy tariffs at peak and off-peak hours, the prices of available equipment, the average values of fees interest will be calculated based on estimates of the cost of implementation and operation over the 25-year horizon. The economic analysis will be carried out on top of the discounted cash flow, the evaluation criteria considered will be: the net present value, the internal rate of return, the payback period and the minimum attractiveness rate adopted, with this it will be possible to assess whether the investment is feasible or not. The main proposal is to design a PV plant with the capacity to supply electricity consumption at peak times, replacing the current diesel generation, so two alternatives were presented for PV plant, the first being an offgrid plant that would supply only consumption at HP and a second alternative is a hybrid PV plant that would take advantage of all available area of the roof and generate the maximum possible energy for the electrical system, that is, it would meet the consumption in the HP and inject the surplus energy into the network, generating energy credits to reduce the energy cost. from the company. Throughout the study, the main components of the PV system will be dimensioned, taking into account technical and economic considerations, the technical dimensioning will be carried out with the help of the Solarius PV software, which consists of the optimized specification of solar modules, inverters, batteries, controllers, cabling and protections and the results obtained revealed that the projects presented by the PV plant, in the two proposals, manage to remunerate the company.
