In 20 seconds
TNB dates the Kangkar Tebrau substation fire to 18:03 Malaysia time on 16 October.
The utility reports full restoration to the affected areas within 77 minutes; individual household durations are not established.
TNB’s 17 October release reports two technical personnel injured and in stable condition; this is dated information.
Six areas named in the operator’s account
The fire disrupted electricity supply in Bandar Dato Onn, Taman Daya, Kempas, Bandar Ulu Tiram, Desa Tebrau and Johor Jaya, according to TNB. These are the places named in the operator’s account of the incident. The release does not supply a customer count or exact affected street boundaries, and it does not establish that the whole of Johor Bahru lost power.
TNB says its technical teams restored electricity in stages and completed restoration to all affected areas within 77 minutes. That is the utility’s account of recovery, rather than an independently measured interruption duration at every address. The available evidence does not establish a separately verified physical completion timestamp. This report concerns the 16 October incident and does not establish the current supply condition of an individual property.

Fire timing and investigation
The operator dates the fire to 18:03 Malaysia time on 16 October, equivalent to 10:03 UTC. Its release was issued at 10:00 Malaysia time on 17 October, equivalent to 02:00 UTC. The release time is distinct from the fire time and the restoration process. It is a retrospective account, rather than evidence of a new outage on 17 October.
In that 17 October release, TNB reports that two technical personnel were injured and were in stable condition. This condition reflects the dated statement, rather than a fresh medical update. The fire cause remained under investigation. The available report does not establish a technical root cause, so the fire should not be attributed to a particular equipment failure.
Planning for essential devices
The essential-device checklist can help organise a small backup kit. Use the runtime calculator to compare device demand with battery capacity, or the internet backup guide to review communications equipment. These resources support preparation; they cannot determine the status of a local electricity connection.
