Zerbattiya is one of the remote areas in Iraq that have retained their old generation stations and networks despite their expansion. As the rehabilitation of these stations and networks is extremely costly, supplying renewable energy sources to these regions is reasonable. The problem in Zerbattiya is that electricity supply comprises 75% of the total energy load. In this regard, we propose the use of a hybrid system using renewable energy with the national grid as a means of compensating for power supply shortage. The proposed system composed of grid, wind turbines, solar panels, converters, batteries, and auxiliary tools. The most optimal system configuration was determined with HOMER. Meanwhile, the average life expectancy of the proposed system is 20 years. Three on-grid scenarios were considered for power generation. The most suitable system was determined in WT-grid hybrid systems. The results showed that the NWT, NBT, Nconv, COE, NPC, Operating cost, and IC are 61, 4, 12, 0.0349 US$/KWh, US$1.32 million, 23,982 US$/year, and US$1.05 million respectively.
