The effect of the World Cup on the electricity sector was not limited to Brazil's games. After the ONS (National Electric System Operator) recorded strong fluctuations in load during the Brazilian team's matches, data from Cammesa (Compañía Administradora del Mercado Mayorista Eléctrico) shows that Argentina also experienced similar behavior in the 3-2 victory over Egypt, this Tuesday (7).
During the match, the demand for energy in the Argentine electrical system fell by approximately 4,4 GW – equivalent to a reduction of about 19% compared to the reference load. According to Cammesa, the load went from 23,4 GW at 11:00 AM to about 19 GW at 3:00 PM, reaching a low of 18,8 GW shortly afterwards.
In proportional terms, the behavior was similar to that observed in Brazil during the 2-1 victory over Japan. On that occasion, the ONS (National System Operator) recorded a reduction of approximately 21% in the load of the SIN (National Interconnected System) – one of the largest fluctuations recorded so far during the Brazilian national team's matches in the World Cup.
Although the two electrical systems have quite different dimensions, the percentage comparison highlights a common phenomenon: the ability of large sporting events to alter the routine of millions of people at the same time, reducing energy consumption in homes, businesses, and other sectors during the matches.
For electrical system operators, these variations represent an operational challenge. In addition to the drop during the game, demand usually recovers quickly during halftime and after the final whistle. In the Brazilian case, this movement is even more complex due to the size of the National Interconnected System (SIN) and the limitations of the transmission network to absorb and distribute the growing energy generation from renewable power plants.
The comparative analysis between the CAMMESA and ONS data, including the selection of the analysis window, the normalization of load curves, and the calculation of the percentage variation, was based on the following reference: study published by Felipe Figueiró, market intelligence and strategy consultant for energy. The data used is public and made available by the operators of the electrical systems in Argentina and Brazil.
