Overview
- Planned five‑hour maintenance outages were carried out across Chennai on June 10 and June 11 to replace equipment and upgrade local lines while other cities including Delhi and Bengaluru ran similar pre‑monsoon shutdowns.
- TANGEDCO says frequent unplanned blackouts are driven by failing transformers, damaged underground and overhead cables, and heavy air‑conditioning loads that cause repeated tripping on the distribution network.
- The state has identified about 20 chronic ‘black spots’ in Chennai and has formed 10 monitoring teams, deployed 125 patrol/restoration vehicles and set up extra Fuse‑off call centres to speed fault detection and repair.
- Residents reported overnight and recurring cuts that disrupted sleep, work and small businesses, prompting street protests and sharp criticism from opposition leaders who say the state must speed permanent infrastructure renewal.
- Officials say there is no generation shortfall and that long‑deferred distribution investment, staff gaps, equipment theft and ageing assets are the central constraints that must be addressed to prevent further summer disruption.
