On Tuesday, blackouts were reported in various states of the country due to a series of situations in various generation plants that affected the electricity supply.
According to the National Energy Control Center (Cenace), these incidents affected the electricity generation capacity.
Last year, faced with a similar situation, Cenace explained that, usually, the maximum annual demand for electrical energy occurs during June and July due to the increase in temperature.
However, according to the National Water Commission (Conagua), currently the anticyclonic circulation at medium levels of the atmosphere located over the country will cause maximum temperatures above 45 degrees Celsius in several states, which translates into the second wave. of heat so far in 2024.
According to Cenace, the rule indicates that when the operational reserve registers rates below 6%, an operational state of alert must be declared, without this meaning an emergency, since there is sufficient reserve to supply the country’s consumption.
Meanwhile, the operating state of emergency is declared when the operating reserve margin is less than 3%.
The reserve margin is the amount of energy that is maintained in the National Interconnected System (SIN) as a backup for possible variations in demand. In this sense, maintaining at least the threshold established for the reserve implies that demand is being satisfied.

On Tuesday night, Cenace reported through a statement that a total of 1,299 megawatts (MW) of generation capacity came into service.
“Due to the increase in nighttime demand and the disconnection of generation, at 7:10 p.m., an emergency operating state was declared again, due to continuing with an operating reserve of less than 3%,” he explained.
From that moment on, he added, it was required to rotate the supply of electrical energy by up to 2,610 MW (which represented 5.23% of the maximum demand of the day) to maintain the safety and reliability of the rest of the electrical system.
At 8:10 p.m., the reconnection of the affected electricity supply began, with this process expected to conclude around 11:00 p.m., Cenace said.
“During this atypical situation in the electrical system, permanent coordination is maintained with the CFE, as well as with the affected generating plants to ensure their recovery,” the public body concluded.
Previously, the agency had reported that between 5:04 p.m. and 5:52 p.m., that is, a period of 48 minutes, the SIN was also in an emergency operating state.
