This advisory is particularly useful for people working from home, travellers staying in local accommodations and those heading out early.
Scheduled power shutdowns are part of infrastructure upkeep to maintain a reliable electricity supply in the long term. Residents and businesses are encouraged to follow local notices from TANGEDCO for any updates or changes in the schedule.
