Energia fotovoltaica em pequenos aeroportos: um estudo de caso para o aeroporto de Maricá

Abstract

Airports are buildings with high consumption of electricity and that need a firm energy supply due to the intrinsic risks of a failure in the airport operating system. Because they have an area of free shading and sunny, these buildings have great potential for the application of PV systems. Most of the electricity consumption at the municipal airport of Maricá occurs during the day and outside peak hours, coinciding with the moment of greater production of solar energy. Currently, the airport in Marica has a costly expenditure on electricity because it does not use 1⁄4 of the contracted demand and frequently uses generators. In addition, the Maricá City Hall is seeking public policies to make the city sustainable, formulating the Maricá Solar Program. Thus, in order to adhere to the Municipal Program, reduce the airport's energy dependence on local concessionaires and reduce the cost of energy, and consequently, generate a reduction in municipal public expenses, since the airport is managed by a state-owned company, the present study aims to evaluate the potential energy and economic viability of deploying solar energy at Maricá airport. For this purpose, financial indicators such as NPV, IRR and Payback were used and the energy viability assessment was carried out using the PVsyst program. In this way, the results showed that the system is viable, as it will have a NPV of R$ 4,186,157.87 for the period of 25 years, will produce a total energy of 445 MWh/year, generating annual savings of R$ 352,299.72 and a reduction of 1,748 tons of CO2.
