The energy load of the National Interconnected System (SIN) should reach 70,849 average megawatts (MWmed) by the end of June, an advance of 3.5% compared to the same period in 2022, informed the National Electric System Operator (ONS) in the most recent Monthly Operation Program (PMO). The amount considers the impacts of the Micro and Mini-Generation Distributed (MMGD) systems on the system.
This month, the Operator estimates an increase in the load in three of the four subsystems of the SIN, compared to the same period last year: in the Southeast/Central-West, the largest load center in the country, a 2.2% increase in load is expected, at 39,818 MWmed. In the Northeast, the expectation is for a 5.3% increase, reaching 11,549 MWh. In the North, ONS projects an increase of 16.4%, to 7,245 MW. On the other hand, for the South, the load is expected to decrease by 0.4%, to 12,237 MW.
Regarding the conditions for energy generation, ONS estimates that the Affluent Natural Energy (ANE), the amount of water that reaches the reservoirs of the hydroelectric plants to be transformed into energy, will reach 89% of the historical average in the Southeast/Central-West, considered the water reservoir of the country's electrical system. If the forecast is confirmed, the region's reservoirs will end the month with 86.3% of their capacity.
In the South, the ANE should be 61% of average, with the amount of water stored at 88.1%. In the Northeast, the ANE is estimated at 48%, bringing the storage to 48%, while in the North the amount of water reaching the reservoirs should end the month at 87% of the average, and the storage at 93%.
