The ONS (National Electric System Operator) predicts a further reduction in the capacity level of Brazilian reservoirs for August, due to the effects of the water crisis. Of the four subsystems, all should record a drop in flow, with rates even more critical than in relation to July.
In the Southeast/Central-West system – responsible for supplying around 70% of the country's energy – the expectation is to end the month with an average reduction of 17% in relation to current records. Capacity, in this case, would drop from 25.9% to 21.4%.
In the South, storage is expected to register a reduction of 46.5%, the largest among all subsystems. The entity believes that by the end of August the average percentage level of the region's reservoirs will be 25.6%, whereas it is currently at 47.9%.
In the North region, the estimate is that the river basins will end the month with 74.1%, and in the Northeast, with 49% of their capacity, which would represent a reduction of 6.2% and 10.4%, respectively. Currently, the subsystem in the North region has 79% of its flow in operation, while in the Northeast the index is 54.7%.
Plants with less capacity currently in operation:
- Itumbiara: 12,09%
- Red Water: 12,91%
- New Bridge: 13,36%
- Embarkation: 14,69%
- Wasp: 16,13%
Maximum storage capacity per MW/month:
- Southeast/Midwest: 203.567,078
- South: 19.897,047
- North East: 51.602,07
- North: 15.164,887
Electricity bill
The lack of water resources in the main Brazilian reservoirs in the midst of the water crisis, caused ANEEL (National Electric Energy Agency) to inform, last Friday (30), that the value of the extra charge on the electricity bill will continue to increase. August under red flag 2, at a cost of R$ 9.49 for every 100 kWh consumed.
The value is 52% higher than that recorded in June, when this flag was also in force and cost R$ 6.24 for every 100 kWh. The adjustment was made in July and, according to the Agency, there is the possibility of a new increase occurring soon.
Less than a month ago, ANEEL opened a public consultation to decide whether the red flag rate, at level 2, would remain at R$ 9.49 per 100 kWh or whether it would be increased to R$ 11.5 per 100 kWh, precisely, due to the current water crisis, which is the worst in the last 91 years, according to ONS records. At the time, despite the discussion, the entity decided not to increase the tariff.
