Eskom CE Tshediso Matona says the cost of running the OCGTs must be weighed against the cost to the economy of blackouts. "Do you stop spending R1bn-R2bn on the OCGTs and put the economy through the pain of daily load shedding? We have decided inside Eskom that the cost of load shedding will be greater than R2bn," says Matona. Moreover, the utility does have a budget for the expensive stations. "If we didn’t have a budget for them, we wouldn’t be running them."
However, for the year ending March, Eskom had budgeted R7bn, which ran out in January, says finance director Tsholofelo Molefe. That prompted public enterprises minister Lynne Brown to tell government incorrectly in December that the utility would run out of cash in mid-January. Just as Matona raises the prospect of switching off the turbines, senior Eskom officials have repeatedly raised the possibility of pulling the plug in the past year. But can Eskom really afford to?
Eskom is damned if it runs them, as it has been since August last year. It is also damned if it pulls the plug on the turbines. That’s a classic case of being stuck between a rock and a hard place — much harder.
Says Matona: "We have virtually used up our budget for diesel. We can no longer re-direct any further funds to diesel as doing so would compromise other core activities."
Keeping the turbines spinning also gives it room to do regular maintenance on its coal plants. "We acknowledge that keeping the lights on at any cost is not sustainable but Eskom is not in the business of switching off the lights," says Matona.
