What caused the JBay power failure

1. The electricity supply to Jeffreys Bay was interrupted at about 11am on Saturday, 27 December. On investigation it was found that a joint had come lose on a main line. It usually takes about three hours to repair faults of this nature.

2. The repairs were done within the given timeframe. However, the electricity could still not be restored.

3. On further investigation it was found that a 9m cross arm holding up main incoming lines had burnt out, bringing the lines crashing down. Three lines had to be checked for damage and pulled back up before the power could be restored.

4. The rainy weather and locality of the fault delayed repairs. The fault was off-road between the Hankey-Humansdorp Road and Mentorskraal. Repair vehicles, including a crane that was brought in from Uitenhage, got stuck in the mud. TLBs had to be brought in to tow them out.

5. Work continued throughout the night. The lines were pulled up in the morning and tightened. To prevent the system from overloading the electricity was switched on bit by bit from 14.30.

6. Despite staggering the switch on and waiting for the load to recede, the power did overload in some areas and had to be switched on again.

7. The main problem was Aston Bay and Paradise Beach where fuses on the lines blew after switch on. This was repaired overnight.

8. At about 7.30 yesterday morning the power supply was interrupted again. A line had come lose at the Melkhout substation near Humansdorp and Hankey. This was repaired and the power restored to most of JBay. Small sections tripped again but was attended to.

    I see there is nothing about what work was done between 16:00 on Saturday afternoon and 11:00 Sunday morning.
    Why the 2 wheel drive bakkie got stuck on the side of a dry old dam. (Stupid place to park a 2 wheel drive bakkie in the rain.)
    Why the 750kg chain hoist failed while pulling up the one phase. (Should have used a 1500kg chain hoist due to the wait of the conductor, the clutch in the hoist stripped and some person could have been seriously injured.)
    The number of OHS Act regulations that where disregarded during the entire time.
    The Munic spend a lot of money on upgrading the overhead line to Aston Bay and Paradise Beach yet when the power goes off it takes such a long time to get their power back on.
