Residents of Grajaú in southern São Paulo set fire to tires on Avenida Belmira Marin on Friday morning, December 12, protesting Enel, the electricity concessionaire for the capital and metropolitan region, after 48 hours of power supply interruptions, according to Metropoles on X. The blockade occurred yesterday morning amid ongoing frustration with the extended outage affecting the neighborhood. Enel provides electricity services across São Paulo city and its surrounding metropolitan area, as noted in the Metropoles report published within the past three hours. No further details on the protest's duration, police response, or resolution were available in the source from Metropoles.
