Gestão de energia: um olhar em retrospecto sobre a tomada de decisão da parada de um gerador a vaporUm olhar em retrospecto sobre a tomada de decisão da parada de um gerador a vapor

Abstract

In February 2022, the drop in electricity prices in the short-term market to their floor level, coupled with the prospect of rising eucalyptus biomass prices, brought into question the economic viability of operating a steam generator at a recycled paper production plant. This context led to a swift decision to discontinue the cogeneration operation. In a reexamination of the business and market scenario at that time, an economic feasibility study of the self-production of electricity is proposed, taking into account variables such as energy prices, tariffs, and contracts, the price of biomass used as cogeneration input, as well as indicators like load factor and demand. The goal is to evaluate the gains and losses of the operation, considering possible opportunities for reducing demand contracts with the energy utility and lowering TUSD (Distribution System Usage Tariff) and TE (Energy Tariff) bills.
