A resident of Kochadai, Ramachandran, who spent a sleepless night, said the inverter battery ran out of backup. However, it’s a challenging task for the Tangedco personnel as they were keenly engaged in restoring the power supply. According to sources from Tangedco, strong winds downed several trees and power lines, causing power outages. Nearly 30 electricity poles were damaged by destructive winds. With limited human resources, the personnel worked throughout the night to ensure the entire supply is back before daybreak on Thursday.
