Análise financeira do custo da interrupção de energia e viabilidade da implementação de backup por estratégias tarifárias em estabelecimentos comerciais caracterizados como microempresas e empresas de pequeno porte

Abstract

Economic Feasibility Analysis of a Backup Energy System for Micro and Small Enterprises (MSEs). The study focuses on the financial analysis of losses caused by power outages (lost profits). The objective is to determine the feasibility of installing a hybrid photovoltaic generation system with a battery bank. The methodology includes creating a consumption and revenue profile for MSEs in Teresina-PI, followed by system sizing and analysis of financial indicators. Furthermore, it explores the use of tariff strategies (White and Conventional Tariffs) to optimize energy injection and consumption, seeking the lowest possible expense. Economic indicators such as NPV, IRR, and Payback demonstrate the financial superiority of investing in solar power plants, whether alone or combined with a battery bank. The scenarios presented show that an on-grid power plant requires the lowest initial investment. The conventional hybrid system with the White Tariff offers the greatest energy security, while the Hybrid B plant with the White Tariff has the shortest payback period. Furthermore, it is evident that all scenarios represent excellent investments compared to a risk-free investment.
