Demand in Argentina’s national electricity system reached a record 29,601 MW at 2:40 pm yesterday as a result of the heat wave affecting Greater Buenos Aires and a large part of the country. Due to the peak load, there were power cuts in the province of Buenos Aires and the capital.

According to data from concessionaires, more than 42 thousand Edesur users and almost 17 thousand Edenor users were left without electricity on Thursday afternoon while the temperature approached 38ºC in the city of Buenos Aires and 39ºC in the metropolitan region of Buenos Aires. Argentine capital.

The new peak in demand easily left behind the previous all-time maximum of a working day recorded on March 13 last year, when the system recorded an instantaneous load of 29,105 Mw.

According to the electrical service status figures published on the official website of the National Electricity Regulatory Entity (ENRE), at 3:05 pm on Thursday, around 42,015 Edesur customers remained without electricity supply and 16,895 Edenor customers.

Despite the national record, both distributors reported during the afternoon that their services did not exceed their respective historical maximums, and that the marks of 4,556 MW for Edesur and 5,941 for Edenor remain in force.

Given the high demand, the Ministry of Energy decided to increase the daily averages of electricity imports from neighboring countries and put into operation minimum technical reserves to mitigate system saturation.

Distribution companies have reiterated the recommendation that users make appropriate use of electrical appliances at home and at work and, in this way, contribute to making the use of electrical system resources more efficient.

Energy demand was met by 55% from thermal generation sources, 4% from nuclear sources, 10% from renewables, 23% from hydroelectric generation greater than 50Mw and 8% from imports.

The Ministry of Energy announced that, due to the system’s level of demand, which could last for several days with the heat wave expected to continue, it has established measures to supply the Interconnected System (SADI) with greater energy.

In the first case, an average daily import of electricity was set from Brazil at 1,529 MW, from Uruguay at 177 MW, from Bolivia at 100 MW and from Chile at 80 MW, to complete the generation supply. On the other hand, he ordered the system to operate with “minimum technical reserves to avoid untimely collapses”.

“These measures seek to mitigate a system that is currently saturated and on the verge of collapse, the product of years of lack of investment and frozen tariffs. This generated extreme vulnerability of the system, evident in the levels of minimum reserves”, said the ministry led by minister Eduardo Rodríguez.
