Almost 15 months into the job, and the boss of South Africa’s state-owned electricity company is getting to grips with issues spanning corruption to defective power plants that threatened to collapse the grid.

“The days of surprises are over,” Eskom CEO Phakamani Hadebe said in an interview on Tuesday . “We just have to speed up the process of turning things around.’’

Hadebe said a “breakdown in corporate governance’’ and the financial viability of the business were the biggest challenges when he was appointed after President Cyril Ramaphosa took over leadership of the country. The CEO also faced increasing operational issues, forcing Eskom to implement periodic power cuts from December to March. Now the situation is under control, he said.

The utility, which provides 95% of the electricity to South Africa, announced earlier this month a plan to minimise power cuts after an assessment with a technical review team identified the root causes of unplanned breakdowns.

“We know what needs to be done and we have an idea of how it should be done and we’re in a better space now,’’ he said. “We have reason to have high expectations.’’

The new Medupi and Kusile plants have ballooned to more than R300-billion, and the discovery of defects will add further to their cost. Still, Hadebe said there are encouraging signs for the next boilers to come online.

‘Death spiral’

Ramaphosa in February announced plans to divide Eskom into generation, transmission and distribution units, as it joins other utilities in experiencing the so-called “death spiral”, where demand is in terminal decline as alternative sources of electricity become available such as solar panels and clients switch to more efficient equipment like LED lights.

The split helps to achieve transparency and will allow for “clarity of operations” and more accountability by managers for the performance of stations and units, according to Hadebe.

Revenue will continue to drop by one percentage point a year, which is about R2-billion, he said. Eskom can make a difference by reducing costs, primarily through procurement and coal purchases, Hadebe said.

When Hadebe worked at national treasury until 2008, one of his responsibilities was to look at the financial oversight of state-owned companies including Eskom. The utility’s debt has since increased more than 11-fold to R450-billion, he said.

The malfeasance, which boosted Eskom’s debt and the tackling of which was a large part of his original mandate, has largely been addressed, according to Hadebe.
