Eskom CEO Andre De Ruyter says there is now clear evidence that the electrical grid is being sabotaged to force the country into loadshedding.
He says distribution lines of a pylon at the Lethabo Power Station in the Free State were cut. It caused the pylon to topple over.
The pylon fell just before 18:00 on Wednesday evening, immediately before evening peak demand hours. The matter has been handed over to the Hawks.
