Chennai Power Cut Today: Several areas of Chennai are facing scheduled power interruptions on Tuesday, August 18, 2026, due to maintenance work by the Tamil Nadu electricity distribution authorities. Most planned outages are expected to take place during the 9 AM to 2 PM window, although some locations may experience extended shutdowns depending on the maintenance work.
Residents are advised to check the latest local shutdown schedule before planning work, travel or other activities that depend on electricity.
Chennai Power Cut Today: Why Is Power Supply Being Cut?
The scheduled outages are being carried out to facilitate maintenance and servicing of electrical infrastructure, including substations, feeders and distribution networks.
Temporary shutdowns allow electricity officials and field workers to undertake maintenance work safely and help improve the reliability of the power supply.
Chennai Power Cut Timings Today, August 18
The main scheduled maintenance window is expected to run from around 9 AM to 2 PM in several affected areas.
However, timings can vary between individual feeder zones. Some locations may have extended maintenance windows until around 4 PM, depending on the nature and progress of the work.
Residents should therefore check their specific locality rather than assuming that electricity will return at the same time across Chennai.
Chennai Power Cut Today: Areas Affected
Several residential and suburban areas have been included in the reported shutdown schedule. Major locations mentioned include:
- Pallavaram
- Thiruvanmiyur
- Puzhal
- Adyar
- K.K. Nagar
- Perambur
- Tambaram
The exact streets and feeder-wise areas can differ, so residents should verify the detailed list before relying on the broader locality names.
Chennai Power Shutdown: Check Your Street-Wise Schedule
Residents can check the street-by-street shutdown information through the official electricity outage portal.
This is particularly important because a scheduled shutdown may affect only selected streets or feeders within a larger neighbourhood, while nearby areas may continue to receive electricity.

Will Power Be Restored By 2 PM?
Electricity is expected to be restored in most areas after the scheduled maintenance window, but the exact restoration time depends on the work being carried out.
If maintenance is completed early, supply may return before the announced deadline. In some feeder zones, however, restoration could take longer and extend into the afternoon.
Residents should wait for official restoration updates if their locality remains without power beyond the scheduled time.
Chennai Power Cut: Unscheduled Outages Also Reported
Apart from planned maintenance shutdowns, unannounced power interruptions have also been reported in parts of Chennai.
Residents experiencing an outage outside the scheduled maintenance period should check for local fault information and contact the electricity authorities where necessary.
What Should Chennai Residents Do During The Power Cut?
Residents can take a few simple precautions before the scheduled outage:
- Charge mobile phones, laptops and power banks in advance.
- Save important work before the electricity goes off.
- Keep emergency lights or torches ready.
- Avoid using elevators around the expected shutdown and restoration period.
- Keep essential electrical appliances switched off during the outage.
- Check the official shutdown portal for updates.
- Follow local electricity authority instructions if restoration is delayed.
Chennai Power Cut Today: What To Know Before Stepping Out
People working from home or running businesses in affected areas should plan, particularly if they depend on internet routers, computers or other electrical equipment.
Residents should also remember that the shutdown timings are locality-specific and can change depending on maintenance requirements.
For the latest information, checking the official TNEB/TANGEDCO outage portal remains the most reliable option for confirming whether a particular street is affected.
