On Friday, August 21, 2026, Tamil Nadu Generation and Distribution Corporation (TANGEDCO) announced planned grid maintenance. Power supply will remain suspended across key Chennai neighbourhoods from 9:00 AM to 2:00 PM. Electricity supply will return earlier if technical crews complete servicing ahead of schedule. Morning web searches for Chennai power cut today spiked as residents prepared for local outages.
Major local areas affected include Mudichur, Adyar, Thiruvanmiyur, Pallikaranai, and Perumbakkam subdivisions. Field technicians will repair sub-station transformers, trim overhead tree branches, and inspect feeder cables. These essential maintenance works prevent sudden power failures during peak operational demands. Residents must plan daily routines carefully around these designated five-hour outage windows.

Avoid using residential elevators near shutdown times to prevent getting trapped inside. Unplug sensitive household appliances to protect against sudden post-restoration voltage surges.
