Since the 70s, Brazil has been facing periods of financial restrictions and crises in the national electricity sector. Strategies to control the load curve mainly at the peak hours must start to be priority in the electricity sector. One option of displacement of this load is the use of Photovoltaic generators (PV) connected to the utility grid. It is observed that the peak load over the day due to air-conditioning use occurs when the solar availability is high. The load curves, for regions of "daytime consumption", will be analyzed and compared with the capacity of PV generation. Therefore, the Effective Load-Carrying Capacity (ELCC) of PV systems connected to the utility grid will be calculated, translating the capacity of PV plants of guaranteeing the supply of the load for a specific region analyzed. The ELCC will be relevant when adequate solar radiation exists and increasing energy consumption occurs, as well as when it is necessary to expand the electrical system, mainly transmission and distribution. The analysis can be made for any region in which solar generation and power consumption data are available. The study will help to verify the efficiency of PV systems to reduce the peak load over the day. This work aims to establish a methodology of identification of regions where PV generation can be applied for maximum benefits.
