Why South Africa has blackouts and ‘load shedding’

Rolling blackouts last year had South Africans firing up candles, flashlights and generators after crisis-plagued Eskom Holdings SOC Ltd., which provides most of the country’s electricity, failed to meet demand. The power crunch has since eased thanks to fewer unplanned plant breakdowns and the use of diesel-powered generators to augment supply. But Eskom’s problems run far deeper than temporary shortfalls. The state-owned utility is mired in debt and isn’t selling enough power to cover all its costs, leaving it scrambling for money to replace aging plants. Now South Africa is weighing a plan to split Eskom into three entities in the hope of reviving its fortunes.

1. What caused the power shortages?

Theoretically Eskom should be able to generate about 47,000 megawatts of power, but output slipped to as low as 26,000 megawatts last year when several of its plants were being serviced or broke down. Less than three quarters of installed capacity has been available this year, in part because a lack of money forced the utility to cut back on maintenance and repairs. It also lacks key technical skills needed to carry out the work, despite having a bloated workforce. Plants that produce more than half the utility’s power are at, or nearing, their ideal retirement age.

2. How did this happen?

South Africa was able to produced more electricity than it needed when white-minority rule ended in 1994, but the government didn’t foresee how sharply demand would spike as the economy expanded and previously neglected black areas were connected to the grid. Eskom announced a series of multi-billion dollar investments after the government awoke to the severity of the problem in the mid-2000s, but the projects came too late and took too long to build. The first wide-scale outages occurred in late 2005. The Medupi and Kusile coal-fired plants, which were supposed to add almost 9,600 megawatts to the grid and be fully operational in 2015, are still years away from completion. Their projected costs have more than doubled to 292.5 billion rand ($21.5 billion).

3. Where was management?

The utility went through repeated board and management changes during the almost nine years Jacob Zuma was South Africa’s president. Investigations by lawmakers and the nation’s graft ombudsman alleged that the upheaval was part of an orchestrated attempt by Zuma’s allies to raid Eskom’s coffers with his tacit consent. Accusations that the utility was looted are now being investigated by a judicial commission. Zuma and his allies deny wrongdoing. Eskom’s board and management were replaced in January 2018, the month after Cyril Ramaphosa succeeded Zuma as head of the ruling party, the African National Congress. Since then, there’s been a concerted effort to stamp out graft, and a number of senior executives and staff have left the company. Ramaphosa was named president in February 2018, after the ANC forced Zuma to step down.

4. How precarious is Eskom’s financial position?

Very. By its own admission, it’s in a “death spiral.” It is saddled with 419 billion rand worth of debt that it’s battling to service, and it anticipates showing a loss of about 20 billion rand for the year ending in March. Sales volumes are at a decade low and continue to fall as the economy stagnates. Increasing numbers of businesses and middle-class consumers have moved off the grid as the price of renewable energy drops. Meanwhile, near-bankrupt municipalities are falling behind in in paying their bills as many customers in impoverished townships default on their debts or steal power through illegal connections.

Sowetans attack Eskom for blackouts

Eskom is under attack – by the City of Joburg and the regional ANC over the almost week-long spate of power outages in Soweto.

The council has slammed the power utility for inefficiency and for failing to deliver on its mandate.

The City of Joburg claimed areas supplied by its own utility, City Power, still had power, but those Eskom supplied did not.

“This is why new housing and business developments such as RDP houses, flats and hotels have power in the township, while the large part of Soweto supplied by Eskom has been cut off,” said Matshidiso Mfikoe, the city’s mayoral committee member for Environment and Infrastructure Services.

She accused Eskom of being “insensitive” and showing “complete and utter disregard” for the people of Soweto.

But Eskom spokesman Khulu Phasiwe said there was “nothing sinister” about the power outages.

He attributed the blackouts to load shedding and then, when the power was due to be switched on again, overloading that caused the transformer to trip.

“When you have in some houses four or five backrooms using stoves at the same time, there is absolutely no way that the power will hold.

“We can’t control unplanned outages resulting from overloading,” Phasiwe said.

Eskom has been involved in a long-running battle with Soweto consumers over unpaid bills. Phasiwe said Soweto owed Eskom about R8 billion, of which R4bn was overdue.

“Some 84 percent of residents have not been paying their debt. Ideally, you should be having 16 percent not paying and 84 percent paying,” Phasiwe pointed out.

A key dispute – related to the outstanding billing problem – is the installation of prepaid electricity meters in Soweto. Both Eskom and City Power are installing meters for their customers. There have been ongoing protests across Soweto against their installation. Last week, Orlando West residents blockaded streets in protest against Eskom’s prepaid meters.

Mfikoe accused Eskom of changing the payment system unilaterally. She suggested it was inconceivable that the prolonged outages could occur without notice “in the township internationally renowned as home to two Nobel peace laureates, Dr Nelson Mandela and Archbishop Emeritus Desmond Tutu”.

Crisis, what crisis? – Eksdom

THE country is not experiencing a power supply crisis, Eskom said on Monday.

“There is no crisis at Eskom. I think the way Eskom gets reported on creates the perception of a crisis,” CEO Tshediso Matona told reporters in Johannesburg.

Mr Matona said the power utility needed financial stability and additional power to make sure electricity supply was reliable.

He said Eskom sold power cheaply.

“We sell electricity below cost compared to other countries. We have spoken about this before … It is a matter of policy implementation, which we do not do ourselves.”

Eskom did not anticipate implementing its stage-three schedule of rolling blackouts again this month, he said.

“We will probably not go into stage three from this difficult patch, but that will rely on additional power capacity going forward,” Mr Matona said.

Stage one allows for up to 1,000MW of the national load to be shed, stage two for up to 2,000MW and stage three for up to 4,000MW.

Stage-two blackouts went into action on Thursday and stage three on Friday.

Eskom was doing everything possible to manage the outages, Mr Matona said.

“It really pains us to have to load-shed. We know the public is not pleased.”

He said a complete blackout would spell disaster for the country.

“We load-shed out of responsibility … A complete blackout would be catastrophic and can take weeks to recover from.”

Group executive Matshela Koko said he led an investigation into the collapse of the silo at Majuba.

“Majuba is urgent … yes, we had a second crack at Majuba, and we will soon take the public into (our) confidence,” Mr Koko said.

Mr Matona said the blackouts had also affected customers in neighbouring countries.

“There is a perception that we load-shed but continue supplying neighbours with electricity. That is not so, cross-border customers are also affected.”

Mr Matona said electricity supply was expected to be constrained in February and March because of budgetary constraints.

“Our financial director is looking at options in this regard,” he said.

The power supply would depend on the availability of diesel during the period.

Eskom used 140-million litres of diesel to produce power in November.

“We have had situations during this past week where the ordering of diesel was delayed due to budget constraints,” said Mr Matona.

“Sometimes, in terms of logistics, things do not go smoothly between us, PetroSA and other suppliers,” he said.

Berlin fingers NATO for ATC blackouts

The German government has indicated that NATO electronic warfare (EW) training exercises were responsible for civilian ATC radar display blackouts in central Europe on 5 June and 10 June 2014.

IHS Jane’s has obtained the government’s answer to a parliamentary question on 17 July, in which it noted that: “In the relevant time period two separate exercises by NATO forces with EW assets were conducted, in the first case by the Hungarian Air Force and in the second by the Italian Army and [undisclosed] partners.”

Both exercises involved ground-based air defence radar assets and were held under the NATO Electronic Warfare Integration Period programme. The German government statement said this is “especially dedicated to test and train EW in the airspace. Further details at the moment cannot be given, as investigations by EASA and NATO are ongoing”.

Informed by IHS Jane’s about the German information, an Austrian Air Force official would not disclose if Austria was informed about NATO EW activities in its airspace. The official emphasised that during the June incidents, the Air Force retained full coverage of Austrian airspace with its Kreidfeuer situational awareness picture, which is provided by three fixed Selex ES RAT-31L primary radars.
