Análise da viabilidade econômica para implementação de um sistema de armazenamento de energia no horário fora-ponta para consumidores residenciais

Abstract

This work aims to analyze the economic viability of the adhesion of low voltage residential consumers to the White Tariff, together with an energy storage system. These consumers use the Conventional Tariff for billing their energy bills, where consumption is billed for the same amount throughout the day. In contrast, the White Tariff provides Low Voltage (LV) consumers with the option of paying different amounts for the energy consumed depending on the time and day of the week. On weekdays, they will have three different amounts of energy billing, called tariff posts: off-peak, intermediate and peak. During off-peak hours, the energy tariff becomes lower compared to the Conventional Tariff. During intermediate and peak fare times, this fare becomes higher in relation to the Conventional Fare. Clearly, the White Tariff was created to encourage a reduction in consumption during so-called peak hours, when energy demand is very high, causing greater investments by concessionaires. Occasionally, this new tariff modality encourages a change in consumption habits, causing its adhesion to still have a lot of resistance from consumers. Thus, the energy storage system in batteries is proposed, combined with the choice of billing by the White Tariff. This system will use off-peak hours to supply its batteries, with this energy being stored, used at peak hours, generating monthly savings, without changing their consumption habits.
