Eskom suffered a “loss of additional units overnight”, prompting it to escalate its load-shedding level to 2, it said in a statement e-mailed at 6.20am on Friday morning.

The power utility later issued a statement saying it had implemented stage 2 rotational load-shedding from 9am until 11pm today.

Stage 2 load-shedding equates to 2GW of power “to be rotationally load shed nationally at a given period”, Eskom’s statement said.

On Thursday, Eskom announced  stage 1 load-shedding, which equated to removing 1GW from the grid “as a measure of last resort to protect the power system from a total collapse or blackout”.

Johannesburg’s City Power issued a statement on Thursday saying it had averted cutting power in West Rand areas it designates as block 7B thanks to “internal capacity of generating sufficient load”.
