South Africa’s cash-strapped state power company began a second day of controlled blackouts, jeopardizing a recovery in the continent’s most-industrialized economy as investors await a government plan to restructure the utility.
The nation is still struggling from outages in the first quarter that contributed to the biggest economic contraction in a decade. Estimates of the blackouts’ toll range from 1 billion rand ($67 million) to 5 billion rand a day. They could also cost South Africa its last investment-grade credit rating from Moody’s Investors Service, which is due to deliver its next assessment on Nov. 1.
Eskom Holdings SOC Ltd., which provides about 95% of South Africa’s electricity and is seen as the biggest threat to the economy, cut 2,000 megawatts from the grid due to unplanned breakdowns at its plants, it said in a statement late Wednesday. The blackouts could last for a week, Jan Oberholzer, the utility’s chief operating officer, told Talk Radio 702.
If the current level of power cuts continue for that long “that would give you about 0.1% of economic growth that would be lost,” Econometrix Chief Economist Azar Jammine said by phone. “The damage that this is inflicting on the willingness to invest in the economy will be longer term.”
Intermittent blackouts have dogged the economy since late 2005, caused by delays in building new plants, coal shortages and maintenance backlogs.
The government has been promising for months that it’s preparing measures to stabilize the utility, and that its proposals will be unveiled by the end of this month. The plan includes appointing a chief executive officer and splitting Eskom into generating, transmission and distribution units under a state holding company.
Eskom said the latest outages were necessary to prevent a collapse of the electricity grid. It cited a series of issues that have taken more than 10,500 megawatts — or about a quarter of its generation capacity — offline.
A conveyor belt supplying coal to the new Medupi plant, which has had billions of rand in cost overruns and construction delays, failed on Oct. 12, it said. Another five generating units were put out of action by boiler-tube leaks, the utility said.
The company last instituted blackouts more than six months ago, and hopes had risen that its operational problems had been addressed, despite its warnings that the system remained vulnerable.
Eskom has amassed 450 billion rand of debt and relies on state bailouts to remain solvent. It’s battled to meet demand for electricity because most of its plants are old and have been poorly maintained.
A long-awaited blueprint that will determine the country’s electricity-generation mix for the next decade was approved by the cabinet on Wednesday, according to Mineral Resources and Energy Minister Gwede Mantashe. That plan won’t help address the nation’s immediate power crisis.
