This comes after President Cyril Ramaphosa, in his briefing last week, blamed the load-shedding on wet coal and “sabotage”.
He told the nation that possible acts of sabotage had led to a loss of 2,000MW of electricity and the recent stage 6 load-shedding, adding that he had instructed it be investigated.
"The sabotage happened in a way where we lost 2,000MW. The wet coal led to a loss of additional megawatts. All that was a combination. Sabotage is not the only factor that led to load-shedding," he said.
