Solar Energy, Distributed Generation, Law 14300, Injected Energy, SIN
Abstract
Brazil has a predominantly renewable energy matrix. With the growth of wind and solar photovoltaic energy in the country's energy matrix, renewable sources reached a share of 87.9% in 2022. In the same year, distributed generation (DG) reached an installed capacity of 28.4 GW, coming very close to the wind generation capacity in the country, which was 29.8 GW. With a predominantly renewable grid and a significant portion of variable, non-dispatchable renewable energy sources, new challenges also arise. Since the National Operator of the Electric System (ONS) does not have any dispatch control over distributed generation, generation cuts in centralized units are often necessary to balance energy generation/consumption. In order to control the increase in distributed generation, Law 14300 was instituted in 2022. This paper evaluates the impact of this new legislation on both distributed generation and the National Interconnected System (SIN).
