A power load of the National Interconnected System (SIN) in January is estimated at 71,212 average MW, which represents a drop of 1.4%, compared to the same month in 2022. Since November, national energy demand has been showing negative numbers.
According to the most recent bulletin of the Monthly Operation Program, for the period from January 21st to 27th, loads in the Southeast and South regions are estimated, respectively, at 40,321 MWmed (-2.8%) and 13,003 MWmed (-5.6% ). The milder temperatures for the period have contributed to a reduction in electrical demand.
On the other hand, the ONS sees growth in loads in the North (11.6% or 6,381 MWmed) and Northeast (2.3% or 11,507 MWmed) subsystems.
Energy storage
To the updated projections for the Stored Energy (EAR) in hydroelectric plants at the end of January are higher than those previously announced. According to the ONS, the Southeast/Central-West could close the month with storage of 69%, compared to 67% in the previous bulletin.
“If the projection is confirmed, it will be the highest EAR percentage for January in the region in 11 years, when it reached 76.1%”, highlights the entity responsible for managing the SIN.
The prospective scenarios for the other submarkets are: 86.6% in the South (compared to 83.1% indicated last week), 71% (70%) for the Northeast and North with 98.4%, significant growth compared to last week's 70.1% .
Rains
The prospective scenarios of Affluent Natural Energy (ENA), volume of rainfall converted into electrical energy, are above 90% of the Long Term Average (MLT), at the end of January 2023, throughout Brazil. For three subsystems, the estimated ENA is greater than MLT's 100% for the fourth consecutive week.
The Southeast/Mid-West, where around 70% of reservoirs connected to the SIN are located, can register 120% of the MLT (compared to 122% in the previous edition). The North again records the highest index: 152% from MLT (156%). For the Northeast, the ENA estimate, at the end of the month, is 106% from MLT (108%). Finally, the South maintained an upward trend in the ENA projection, with 93% from MLT (84%). The data indicate a rainfall pattern compatible with the humid period.
