Impacto econômico da gestão da energia elétrica na companhia de saneamento de Alagoas (CASAL)

Abstract

This case study focuses on analyzing the financial impact of electrical energy management at the Companhia de Saneamento de Alagoas (CASAL) through four key indicators, providing a comprehensive view of the performance and effectiveness of adopted strategies. The first indicator is the management of distributed generation credits, aiming to quantify the savings resulting from offsetting consumption with surplus credits from photovoltaic generating units compared to the leasing cost of these units. The second indicator is tariff analysis, examining the effects of different electricity tariffs on CASAL's operational costs. It seeks to identify advantageous tariffs and propose adjustments to maximize savings, ensuring CASAL pays the lowest possible amount for consumed energy. The third indicator is energy demand management, examining active and reactive demand peaks and proposing measures to reduce them. By minimizing these peaks, CASAL can avoid additional energy costs and improve its operational and financial efficiency. The last indicator relates to power factor correction, a critical aspect for optimizing electricity use, analyzing measures adopted by CASAL to correct low power factors, aiming to reduce losses and improve energy efficiency in its operations. The continuous analysis of these indicators has led to various positive outcomes from the implementation of distributed generation in CASAL's energy management. Additionally, it has identified areas for improvement in contracted demands, contributed to maintaining corrective actions in controlling costs with excess reactive consumption, and facilitated a more in-depth analysis of Consumer Units (UCs) that have changed their consumption profiles, enabling the evaluation of possible changes in their tariff modalities to ensure more efficient and economical operation. These indicators not only provide a deeper understanding of CASAL's energy use but also offer valuable insights to enhance its financial and environmental sustainability.
