CUSTO DO BOMBEAMENTO DE ÁGUA EM SISTEMA DE IRRIGAÇÃO SOB DIFERENTES MODALIDADES TARIFÁRIAS

Abstract

Irrigation is a high-cost technique that requires good planning, since, depending on climatic conditions, it can become an expensive process, making its use unfeasible. It is estimated that 20% of the water and 30% of the energy consumed during the irrigation process could be saved using simple measures such as determining the amount and timing of water application, selecting the engine starting method and choosing energy tariffs. The law usually authorizes the application of different types of tariffs for companies where concessionaires have a horo-seasonal structure, characterized by different tariffs for electricity consumption (kWh) and power demand (kW), according to the hours. more use on the day and in the periods of the year, aiming at better energy use due to the consumption schedule and reduction of investment needs to serve new consumers. Thus, this work aimed to demonstrate the energy costs variables of pumping water into the irrigation system in different consumption scenarios and energy tariffs.
