For the third week of August, the bulletin of the Monthly Operation Program (PMO), of the National Electric System Operator (ONS), referring to the operational week from 15 to 21/08, foresees a retraction in the Marginal Cost of Operation (CMO) in all regions of the National Interconnected System (SIN). The values of the Southeast / Midwest, South and North subsystems remain equal, as in the previous period, and decreased by 9.3% in the CMO, reaching R $ 90.21 / MWh against R $ 99.51 / MWh. In the Northeast region the reduction is more modest, registering a drop of 2.9%, starting to cost R $ 65.88 / MWh, compared to R $ 67.85 / MWh. The main factor that influenced the reduction of the CMO in all subsystems of the SIN was the update of the flow forecast.

For this week, energy consumption is expected to remain positive for the sixth consecutive week. The growth forecast is 0.6%, compared to the same month last year. The Southeast and North regions indicate positive performance. In the North, the forecast is 4.0% with 5,838 average MW and in the Southeast the expected increase is 0.8% with 37,381 average MW. The Northeast and South subsystems are expected to decline in energy consumption. In the first, the expected decrease is 1.2% with 10,183 average MW and the South with a decrease of 0.2% with 10,978 average MW.

For this operational week in the capitals of the Southeast / Midwest and South regions, the weather indicates milder temperatures than those observed in the current week, due to the passage of two cold fronts through these regions. For the Northeast and North subsystems, temperatures and rains typical for this time of the year and similar to those observed in the current week are expected. It is also worth noting that, in the North subsystem, the unplanned resumption of the load of a free consumer in the basic network influenced the expected growth rate of 4.0%.

The forecast for affluence in the South is 83% of the MLT; in the Southeast / Midwest, 75% of the MLT; followed by the North which should register 71% of the MLT and the Northeast with 67% of the MLT. In the last week, the storage levels of all subsystems have been declining. However, according to the report, there is an indication of rain in the Southeast, at the head of the Tietê river basin. The expected volume for reservoirs for the period is 79.3% for the Northeast; 75.4% for the North; 53.2% for the South and 44.6% for the Southeast.
