The energy load registered last June in the National Interconnected System (SIN) by the National Electric System Operator (ONS) totaled 75,697 average megawatts (Mwmed), signaling an increase of 6.1% compared to June 2023.
In the last 12 months, growth was 7.4% compared to the previous 12 months. The results were released this Thursday (25), in Rio de Janeiro, and are included in the Monthly Cargo Bulletin, prepared by ONS.
The National Electric System Operator is responsible for coordinating and controlling the operation of electricity generation and transmission facilities in the SIN, in addition to planning the operation of the country’s isolated systems.
Under the command of the ONS there are 161 hydroelectric plants in 22 river basins, with multiple owners, which should total almost 110 gigawatts (GW) in the SIN by 2027.
Subsystems
According to the ONS, the expansion of the load was also observed in all subsystems when comparing June 2024 with June 2023. The subsystem with the most significant acceleration was the North, with 8.9% (7,732 MWmed), followed by the Southeast/Central-West, with 6.4% (42,709 Mwmed); South, with 5.9% (12,900 Mwmed); and Northeast, whose advance was 3.5% (12,355 MWmed).
Among the causes that explain this increase in load are the meteorological conditions observed in the Southeast/Central-West subsystem, the main load consumption center in the country, which presented maximum temperatures above the historical average and precipitation levels below the average.
In the period of the last 12 months, the increases in the accumulated figures were 10.2% (North Region), 7.7% (Southeast/Central-West); 7.4% (Northeast); and 4.6% (South).
