A new heat wave Which especially affected the Southeast and Central-West regions, this Monday afternoon (13) Brazil reached a new national record in terms of electricity. According to the National Electric System Operator (ONS), the SIN (National Interconnected System) instantaneous load demand reached a record at 2:17 pm, when the level of 100,955 megawatts (MW) was reached.
This was the first time in SIN’s history that the load crossed the 100,000 MW mark. The previous mark was 97,659 MW, measured on September 26 this year. When the level was recorded, the load was served by 61,649 MW hydraulic generation (61.1%), 10,628 MW thermal generation (10.5%), 9,284 MW wind generation (9.2%), 8,505 MW centralized solar generation (8.4%). ) and 10,898 MW solar generation from micro and small distributed generation – MMGD (10.8%).
This Monday, the National Meteorological Institute (INMET) issued a new warning, extending the red alert until Friday (17). Temperatures must be at least 5ºC above average for a period of more than five days. Sao Paulo city once again had the hottest day of the year. The meteorological station in Mirante de Santana, north of the capital Sao Paulo, recorded 37.4 degrees Celsius at 3 p.m., according to Inmet.
As the report revealed, the most frequently recorded heat waves in the country don’t just cause trouble for people. They have an impact on various activities in the economy, starting to put existing contingency measures into practice and planning new adaptations to long-term warming scenarios.
Among the main impacts, experts highlight an increase in energy costs due to greater use of air conditioning and a decrease in efficiency in the agricultural and aviation sectors.
On Friday (10), the ONS raised its November forecast to 79,780 average megawatts (MWm) in 2022, an increase of 11.0% compared with the same month, compared with a forecast of 10.6% in the previous week. They also revised down their forecast for rainfall reaching hydropower plants in the south in November, while also reducing their forecast for flows in the north.
According to the bulletin, rainfall reaching plant reservoirs in the south in October was estimated to be 437% of the historical average, compared to 384% predicted in the previous week. For other regions, flows are forecast to be below historical averages, 52% in the North (compared to 68%), 43% in the Northeast (compared to 32%) and 88% in the Southeast/Midwest (compared to previously). in 113%).
Reservoir levels in the Southeast/Midwest, the main reservoirs for hydroelectric power plants, should reach 66.3% at the end of November, slightly lower than the 69.9% estimated in the previous week. (Folhapress)
