Residents in Bengaluru, Chennai, and Delhi must prepare for power disruptions on May 18. Heatwave conditions forced utility providers to schedule maintenance across many major residential hubs. These planned outages aim to prevent grid failure during high peak demand hours. Check local schedules to avoid being caught off guard during your workday.
Providers struggle to balance high loads with older infrastructure. In Delhi, Distribution Companies (DISCOM) manage localized cuts to protect transformers from overheating. Chennai and Bengaluru also face shutdowns for vital grid stabilization work today. Residents should expect these breaks to last nearly six hours in affected areas.

Bengaluru BESCOM Maintenance Timings
The Bangalore Electricity Supply Company (BESCOM) has announced rolling blackouts across several zones. Major areas include parts of JP Nagar, Kengeri, and Whitefield where line shifting continues. Most interruptions occur between 10 AM and 4 PM during shifting operations today. High-rise residents should check backup fuel levels for diesel generators ahead of time.
Chennai TANGEDCO Outage Schedule
Chennai residents face outages as the Tamil Nadu Generation and Distribution Corporation (TANGEDCO) performs maintenance. Power will likely remain off from 9 AM until late in the afternoon. This work ensures the grid remains stable during the intense summer humidity levels. View the table below for specific timings across the major city neighborhoods today.
| City | Areas Affected | Scheduled Timings |
|---|---|---|
| Bengaluru | JP Nagar, Whitefield | 10 AM to 4 PM |
| Chennai | Ambattur, Guindy | 9 AM to 2 PM |
| Delhi | South Delhi, Dwarka | Morning Hours |
Delhi DISCOM Planned Cuts
Delhi providers like BSES and Tata Power prioritize repairs in Dwarka and Rohini today. Heat-related stress on local equipment makes these updates vital for all residents. If your power stays out late, use official mobile apps for status reports. Early alerts for May 19 indicate further cuts in nearby residential clusters.
Staying informed helps you manage your routine during these hot summer months. You can register complaints through official toll-free helplines or SMS services. Keeping your devices charged will help mitigate the impact of these shutdowns. Proactive planning remains essential until the monsoon brings relief to the electricity grids.
