TANGEDCO Power Shutdown Tomorrow: 28-09-2026

Tomorrow, Sunday, September 28, 2026, TANGEDCO has scheduled planned maintenance work across 14 substations covering Coimbatore, Trichy, Karur, Udumalpet, Dharmapuri and a few surrounding pockets. Most outages start at 9:00 AM, and durations range from 5 hours to a full 8 hours depending on the substation. Below is the complete area wise breakdown along with a prep checklist so you can plan your day without any last minute surprises.

Quick Summary Table

If your area doesn’t appear on this list, you shouldn’t expect any planned interruption tomorrow. Any power loss outside this schedule would count as an unplanned fault rather than routine maintenance.

Coimbatore and Annur Belt

This region has the highest number of substations under maintenance tomorrow, five in total, all running the same 9 AM to 2 PM window.

Sulur 110 KV

• Sulur, T.M. Nagar, Ranganathapuram

Why These Cuts Happen

Most of tomorrow’s shutdowns fall under two categories: monthly maintenance, and breaker or accessory servicing for 110kV and 22kV lines. TANGEDCO runs these on a rolling basis across substations throughout the year, so a scheduled cut in your area isn’t unusual, it’s part of routine grid upkeep rather than a sign of a fault or supply issue.

Before the Power Goes Off, Keep These Ready

What If Power Doesn’t Return on Time

Power supply is usually restored close to the listed end time, and sometimes even earlier if the maintenance work finishes ahead of schedule. If your area’s power hasn’t come back a while after the scheduled end time, it likely isn’t connected to this maintenance work. In that case, contact your local TANGEDCO section office directly, or call the state electricity helpline at 1912 to report a possible line fault.

That covers the complete shutdown schedule for September 28, 2026. If your locality isn’t listed above, no outage is currently scheduled for your area tomorrow.
