Microgrids have now become an option for universal access to electricity in rural areas of developing countries. This article analyzes a microgrid designed and installed in 2019 to provide energy access to the inhabitants of Paraje Malvinas, located in the South-East of the Province of Corrientes, Argentina (Latitude 29°38'09.34 S, Longitude 58°59' 15.86 W). The microgrid responds to the configuration of a Solar/Battery/Diesel Hybrid System. The analysis is carried out through values obtained by a simulation and values measured using the existing microgrid configuration considering the energy consumption provided by the Secretary of Energy, with an initial value of 66 kWh/day. The simulated results initially showed that the microgrid supplies electricity with a levelized cost of US$0.329/kWh, with CO2 emissions of 18,500 kg/year and a renewable fraction of 93.8%. Comparing values measured with the initially considering demand, it is verified that it is well above the consumption in the Paraje, which leads to a new simulation considering the real load profiles. Through this new adjusted simulation, it is verified that the Diesel generator does not come into operation at any time to supply the demand, the calculated percentage of solar fraction is not used and results in a System with lower performance than expected. From the results of the comparison, it stands out that the LCOE value is 57% higher than the initially expected value. Therefore, a hybrid microgrid solution from a renewable energy source can be a viable option to electrify areas far from the grid, but the demand must be properly determined since it is essential for the adequate dimensioning of the microgrid.
