The energetic needs of the modern world growth every day, and the energy production demands from safe and renewable sources are growing due to the high levels of pollution. The electrical energy from renewable sources such as wind and solar power, has problems related to its constant production caused by its own features (inconstancy of the winds speed and intermittency of the sunlight availability). For a constant production of energy of those sources, there is a primacy of an energy storage system (ESS), which makes the measurement and the construction difficult. Therefore, the present dissertation shows the measurement, simulation, and the experimental results of energy storage systems based on batteries for grid applications. Three types of technology (lead-acid battery, lithium-ion battery manganese cobalt oxide – NMC and Lithium iron phosphate – LFP) were tested from peak time of use to reduced time of use. The measurement of the batteries (in order to maximize de performance of each technology), resulted in discharges of 23,6% for lead-acid battery, 60% for NMC batteries and 70% for the LFP technology. The simulations were made using the commercial application HOMER. The profile used was in a Federal Institute situated in Búzios, in the state of Rio de Janeiro (Brazil). The results showed that the currently costs for the use of this system are not economically competitive if we only consider the advantages of charge operation. From the comparative point of view of battery technologies assessed in laboratorial analyses, the results showed that the lead-acid battery, although its low costs, may not be the best option, due to its low operational development and poor durability.
