Power cuts in South Africa stifle post-Covid economic recovery

Eskom’s unexpected escalation of load shedding this week has confirmed that South Africa’s post-Covid-19 economic recovery will be throttled by energy constraints, and that unless swift action is taken to support private electricity generation, crippling power cuts will continue for years.

In the meantime, a big shake-up is taking place at Eskom Generation, with the former CEO of the Eskom Generation Division shifted out of the way. The managers of Tutuka and Kendall power stations were also summarily dismissed yesterday pending disciplinary inquiries, and further interventions at Kriel and Duvha power stations are underway.

Lockdowns imposed in South Africa and elsewhere to curb the spread of Covid-19 tipped the domestic economy into its worst recession in nine decades, and business, industry and government have scrambled to get back up and running as restrictions were eased.

But with the pickup in demand for electricity, Eskom’s ageing infrastructure immediately took strain and multiple breakdowns forced the utility to resume load shedding in July to protect the national grid.

By the end of the month, the amount of power reductions for the year had already exceeded the levels seen in 2019, which was the worst year on record.

Eskom insists that its new programme of stepped-up maintenance, which aims to address decades of neglect and mismanagement, will end load shedding within 18 months, but it is increasingly clear that this target will not be met, given the scale of problems at its poorly performing coal-fired power stations.

The solution

The solution is for government to take bold policy initiatives enabling all of Eskom’s customers – industries, municipalities, businesses, farms and households – to rapidly bring on new generation capacity with reliable, low cost and environmentally friendly wind and solar PV installations, together with battery storage.

Self-generation in the private sector has already begun, with an estimated 1,1 GW (1100 MW) of capacity installed – the equivalent of one full stage of load shedding. But policy paralysis and cumbersome, time consuming regulations are still hobbling a process which could address the widening gap between supply and demand of electricity in the economy within just six to 18 months.

Amid the crisis which South Africa now faces, the steps which government has taken to enable self-generation are too little and may quickly become too late. By 2030 several of Eskom’s old coal-fired plants are due to be decommissioned, taking about a quarter of its existing capacity offline, and there is nothing in the pipeline to replace them.

“South Africa has reached a stage where the country simply doesn’t have enough generating capacity which is reliable and which is going to enable the economy not only to recover from Covid-19, but to make any sort of progress over the next ten years,” says Roger Baxter, CEO of the Minerals Council of South Africa.

“As a country we must understand that we have reached a point where government has run out of options and that it has no choice but to bring in private sector participation. Without a reliable electricity grid, without diversified supply and real competition on the generation side of the business, South Africa cannot grow its economy at all. It’ll be gridlock.”

South Africa’s economy grew at an average rate of 4,5% between 2001 and 2008, but in the past decade, growth has averaged 1,5%, shrinking to less than 1% in the past three years. Baxter says that electricity constraints were a big factor, and that the mining sector alone could generate 2,3 GW (2300 MW) of its own power to help alleviate the pressure on Eskom.

The Council for Scientific and Industrial Research (CSIR) predicted in August that load shedding would carry on for two to three years in the absence of enabling regulations to allow and even incentivise “customer response at scale” with self-supply options to supplement Eskom’s existing grid capacity.

“It’s a burning platform that we are on – we need to be moving faster, we need to be doing more,” CSIR chief engineer Jarred Wright said during a presentation of research on the crisis. “An urgent response is needed to both ensure short-term adequacy and to get South Africa on the path to long-term adequacy.”

Scaling up self-generation, which could be installed as early as this year, would be the first step, he said.

The second was completing the Emergency Power Procurement Programme which the government committed to in December 2019, seeking to add between 2000 and 3000 MW to the country’s electricity grid by enlisting the help of the private sector.

But progress has been slow, with the Department of Minerals and Energy (DMRE) only extending requests for project proposals in August – nine months later. The timeline to completion is mid-2022 but given the government’s bureaucratic and sluggish approach to procurement, it may take a year longer.

The third step identified by the CSIR is implementation of the DMRE’s latest Integrated Resource Plan (IRP), a long-term strategy for the country’s future energy mix which was released last October – eight years behind schedule.

Evidence that Eskom’s infrastructure cannot cope is the steady decline in its energy availability factor (EAF) which is the percentage of maximum energy generation that a plant is capable of supplying to an electrical grid over a given period. The EAF fell from more than 90% two decades ago to about 67% in 2019 and has hovered at an average of 66,1% so far this calendar year.

The IRP2019 and the Eskom recovery plan targets an EAF of 78% by the end of 2020, but this is looking hopelessly unrealistic. Eskom’s maintenance drive is vital for stability of supply in the near term, but the utility cannot resurrect its aged infrastructure, and the best which can be hoped for is stabilisation of the EAF at its current, low levels.

Eskom acknowledges that its outdated, vertically integrated electricity supply model is at odds with the global shift towards disaggregated networks, micro-grids, distributed generation, smart-grids, and embedded generation in the private sector.

Last year, President Cyril Ramaphosa announced plans to separate the utility into generation, transmission, and distribution units, but the utility has since indicated that significant headway is difficult before its mammoth and steadily increasing debt burden of R488-billion has been restructured. Ironically, a similar plan was drawn up 22 years ago.

Eskom must borrow to service its debt, and if it were not for the latest government bailout of R49-billion, it would not have been able to meet its repayments of capital and interest in the last financial year.

In a report presented to parliament last week, Eskom said that its debt had climbed ten-fold in the past decade, while tariffs had only increased five-fold, and thus electricity tariffs were still too low and not cost-reflective.

Baxter believes it is unfair for Eskom to insist that tariffs must reflect the cost of its borrowing because much of the debt stems from corruption and mismanagement, particularly related to the construction of Medupi and Kusile –  two new power plants which are now more than six years behind schedule and five times more expensive than originally planned.

“Pricing is a big issue. Competitive pricing and pricing predictability are as important as electricity availability,” says Baxter.

Conclusion

Electricity is not a luxury, intended for the privileged few. It is a vital commodity which the country needs to enable and support economic growth which will lead to poverty alleviation, job creation and the reduction of inequality.

This is summed up in the country’s official National Development Plan 2030 which states, inter alia: “The NDP aims to eliminate poverty and reduce inequality by 2030. According to the plan, South Africa can realise these goals by drawing on the energies of its people, growing an inclusive economy, building capabilities, enhancing the capacity of the state, and promoting leadership and partnerships throughout society.” – https://www.gov.za/issues/national-development-plan-2030

It is therefore incumbent upon the government to take real, measurable, and deliberate action immediately to remedy a situation which is mostly of its own making through the appointment of inappropriate individuals at Eskom and years of political interference in its affairs.
