Shopping mall loses power in the middle of Brazil's game and customers leave; could BESS have prevented the problem?

Fans who were watching the Brazil vs. Japan game, valid for the World Cup and played this Monday (29), were surprised by an interruption in the power supply in a shopping mall in Fortaleza (CE).

Images shared on social media show corridors and establishments without lighting, while hundreds of people quickly leave the area to try and watch the rest of the game elsewhere.

In a statement, Shopping RioMar Kennedy reported that the interruption of the broadcast of the Brazil game was caused by a power supply failure from the utility company, a situation that affected the synchronization process of the mall's emergency power generation system. According to the mall, operations were subsequently restored.

Enel Ceará, in turn, reported that the incident originated in the high-voltage network that supplies the development. According to the distributor, technical teams were mobilized and found that a metal balloon had come into contact with the electrical network, causing the service interruption. The concessionaire also reported that the supply was normalized at 16:01 PM.

Could the BESS system have reduced the impacts?

The case of the RioMar Kennedy Shopping Mall highlights one of the applications of battery energy storage systems (BESS): increasing the energy resilience of large commercial developments.

Depending on the configuration and scaling adopted, the technology can reduce or even prevent interruptions perceived by consumers, acting as a backup and operational support solution.

Yanael Medeiros, engineer at CS Consultoria, the power plant engineering and commissioning unit of the Group. Canal Solar explains that, although the shopping mall already had diesel generators for emergency situations, a BESS system could act in a complementary way, eliminating the interval between the interruption of supply by the utility company and the effective start-up of the generators.

"Because the batteries respond in milliseconds, they keep critical loads energized during power outages and during the generator synchronization process, preventing shutdowns, voltage fluctuations, and interruptions noticeable to consumers," she said.

In addition to increasing the reliability of the electrical system, the professional points out that this type of solution can reduce operational impacts and extend the continuity of activities in commercial and industrial enterprises. "And, as a bonus, nobody would need to rush out of the mall to finish watching the game somewhere else," she emphasized.
