The recurring power outages have ceased to be isolated incidents and have begun to affect several municipalities in Santa Catarina, reinforcing the debate about the responsiveness of Celesc's (the local utility company) distribution network in the face of weather events and increased demand.

In different regions of the state, consumers and municipalities are complaining about power outages mainly associated with heavy rains, strong winds, and trees falling on the power lines. The situation is repeated in several cities served by the company, which is responsible for 295 municipalities, covering practically the entire state territory.

Problems have been reported in locations such as Garopaba, Itapema, Bombinhas, Camboriú, Itajaí, Blumenau, Timbó, Rio dos Cedros, Concórdia, Criciúma, and Araranguá. These are municipalities with distinct realities, but they share similar challenges when adverse weather events occur.

Gaspar

In this broader context, Gaspar stands out as one of the municipalities where the problems have become most evident. The supply failures recorded in recent weeks have caused disruption to the population, commerce, and essential services, increasing the pressure for preventive and structural actions.

Power outages in the city occur frequently, especially on rainy days, highlighting specific vulnerabilities in the local grid. The combination of densely wooded urban areas, city growth, and exposed electrical infrastructure contributes to the increased number of occurrences.

The repeated power outages led the municipality to demand measures that go beyond emergency response, focusing on prevention and planning.

Among the demands presented are the intensification of preventive maintenance, the systematic pruning of trees near the power lines, the identification of critical points, and the evaluation of the need for structural reinforcement in certain sections.

Local assessments suggest that simply restoring service after each outage does not provide a lasting solution to the problem.

Challenge

At the state level, the concessionaire claims to serve a broad and heterogeneous universe of consumers, distributed across hundreds of municipalities with urban, rural, and industrial characteristics.

According to Celesc, this broad reach presents operational challenges, especially during periods of unstable weather, when the volume of incidents tends to increase simultaneously in different regions.
