Chennai experienced significant blackouts on Thursday night due to a fire at the Manali 400/230kV substation in North Chennai, which caused sequential faults in both feeders and disrupted power supply to the city. Power was restored by stepping up 230KV to 400KV and rerouting supply through Pulianthope, according to the Tamil Nadu Generation and Distribution Corporation Limited (TANGEDCO).
“TANGEDCO managed sequential faults on both feeders from NCTPS II to Manali 400/230KV and ensured uninterrupted power to the city by rerouting through Pulianthope,” the corporation stated on X. By 6 am Friday, TANGEDCO had repaired the fault at NCTPS II and resumed power supply through the Manali substation.
