Análise de viabilidade econômica e ambiental da utilização de energia elétrica com sistema Shore Power em um contexto para instalações portuárias Brasileiras

Abstract

Shore Power is one of the names given to the process of using the electrical energy available in maritime installations to supply the demand for electrical energy needed by a vessel during the period in which it is berthed, which can last from a few hours to several days, replacing the use of the vessel's generator (main or auxiliary) for the electrical energy supplied by the port facility. In this way, by not using marine fuel in this process, tons of this fossil fuel, which is rich in sulfur concentrations, is avoided, reducing the emission of CO2, NOx, SOx and other polluting particles into the atmosphere. In addition to emissions, replacing the onboard generator also brings with it the advantage of reducing vibration and noise in the port region. This work takes a bottom-up approach using historical data from the last eleven years of port movement in Brazil to verify what the impact would have been if the use of Shore Power technology had been applied in that period, in addition to indicating the potential for financial gain with its use in the future in the main port facilities in the country. Environmental, regulatory and resource availability issues are also addressed in this context. In addition, it was developed, through a computer tool, entitled "Shore Power System Installation Feasibility Calculator through Monte Carlo Simulation", registered with the National Institute of Industrial Property - INPI (Patents, Computer Programs and Topographies Directorate). of Integrated Circuits), with the aim of reducing, or at least realizing in advance, the impact of the instability of the financial markets, making it possible to plan the business or project using the Shore Power concept. seeking to indicate potential gains from its use, even if its use is not mandatory in the country, but which is shown as a green alternative in the search for the best and most conscious environmental practices, in addition to the creation of investment and technology in the country, both for the sector electricity and for the port.
