The cold corridors of South Africa’s once-mighty Komati coal-fired power plant have been quiet since its shutdown in 2022 in what was trumpeted as a pioneering project in the world’s transition to green energy.
Two years later, plans to repurpose the country’s oldest coal power plant have amounted to little in a process that offers caution and lessons for countries intending to reduce their reliance on fossil fuels and switch to renewables.
Jobs have been lost and construction for wind and solar energy generation has yet to start, with only a few small green projects under way.

“We cannot construct anything. We cannot remove anything from the site,” acting general manager Theven Pillay said at the 63-year-old plant embedded in the coal belt in Mpumalanga province, where the air hangs thick with smog.
Poor planning and delays in paperwork to authorize the full decommissioning of the plant have been the main culprits for the standstill, he said.
“We should have done things earlier. So, we would consider it is not a success,” he said.
Before it turned off the switches in October 2022, the plant fed 121 megawatts (MW) into South Africa’s chronically undersupplied and erratic electricity grid. The transition plan — which won US$497 million in funding from the World Bank — envisions the generation of 150MW via solar and 70MW from wind, with capacity for 150MW of battery storage.
Workers are to be reskilled and the plant’s infrastructure, including its massive cooling towers, repurposed.
However, much of this is still a long way off.
“They effectively just shut down the coal plant and left the people to deal with the outcomes,” South African Deputy Minister of Energy and Electricity Samantha Graham said.
Coal provides 80 percent of South Africa’s power, and the country is among the world’s top 12-largest greenhouse gas emitters. Coal is also a bedrock of its economy, employing about 90,000 people. South Africa was the first country to form a just energy transition partnership (JETP) with international funders to move off dirty power generation, already receiving US$13.6 billion in total in grants and loans, South African presidential JETP committee member Neil Cole said.
Komati is the first coal plant scheduled for decommissioning, with five of the remaining 14 ones meant to follow by 2030. It had directly employed 393 people, the state energy firm Eskom that owns the plant said.
Only 162 remain on site as others volunteered for transfer or accepted payouts. The plant had been the main provider of employment in the small town, where the quiet streets are pitted with chunks of coal. Today, several houses are vacant as workers from other provinces headed home after losing their jobs.
“Our jobs ending traumatized us a lot as a community,” said Sizwe Shandu, 35, who had been contracted as a boilermaker at the plant since 2008.
The shutdown had been unexpected and left his family scrambling to make ends meet, he said.
With South Africa’s unemployment rate topping 33 percent, Shandu now relies on government social grants to buy food and electricity.
Pillay admitted that many people in the town of Komati had a “disgruntled view” of the transition.
One of the mistakes was that coal jobs were closed before new jobs were created, he said.
People from the town did not always have the skills required for the emerging jobs. Eskom has said it plans to eventually create 363 permanent jobs and 2,733 temporary jobs at Komati.
One of the green projects underway combines raising fish alongside vegetable patches supported by solar panels.
Seven people, from a planned 21, have been trained to work on this aquaponics scheme, including Bheki Nkabinde, 37.
“Eskom has helped me big time in terms of getting this opportunity because now I’ve got an income, I can be able to support my family,” Nkabinde said, as he walked among his spinach, tomatoes, parsley and spring onions.
The facility is also turning invasive plants into pellets that are an alternative fuel to coal and assembling mobile micro power grids fixed to containers. A coal milling workshop has been turned into a welding training room.
The missteps at Komati are lessons for other coal-fired power plants marked for shutdown, Pillay said.
For example, some now plan to start up green energy projects parallel to the phasing out of fumes.
However, the country is “not going to be pushed into making a decision around how quickly or how slowly we do the just energy transition based on international expectations,” Graham said.
South Africa has 7 percent renewable energy in its mix, up from 1 percent a decade ago, she said.
It would continue mining and exporting coal, with Eskom estimating that there are about 200 years of supply still in the ground.
The goal is to have a “good energy mix that’s sustainable and stable,” Graham said.
Since South Africa’s JETP was announced, Indonesia, Vietnam and Senegal have struck similar deals, but there has been little progress toward actually closing coal plants under the mechanism.
Among the criticisms is that it offers largely market-rate lending terms, raising the threat of debt repayment problems for recipients.
NOT JUSTIFIED: The bank’s governor said there would only be a rate cut if inflation falls below 1.5% and economic conditions deteriorate, which have not been detected The central bank yesterday kept its key interest rates unchanged for a fifth consecutive quarter, aligning with market expectations, while slightly lowering its inflation outlook amid signs of cooling price pressures. The move came after the US Federal Reserve held rates steady overnight, despite pressure from US President Donald Trump to cut borrowing costs. Central bank board members unanimously voted to maintain the discount rate at 2 percent, the secured loan rate at 2.375 percent and the overnight lending rate at 4.25 percent. “We consider the policy decision appropriate, although it suggests tightening leaning after factoring in slackening inflation and stable GDP growth,”
DIVIDED VIEWS: Although the Fed agreed on holding rates steady, some officials see no rate cuts for this year, while 10 policymakers foresee two or more cuts There are a lot of unknowns about the outlook for the economy and interest rates, but US Federal Reserve Chair Jerome Powell signaled at least one thing seems certain: Higher prices are coming. Fed policymakers voted unanimously to hold interest rates steady at a range of 4.25 percent to 4.50 percent for a fourth straight meeting on Wednesday, as they await clarity on whether tariffs would leave a one-time or more lasting mark on inflation. Powell said it is still unclear how much of the bill would fall on the shoulders of consumers, but he expects to learn more about tariffs
Greek tourism student Katerina quit within a month of starting work at a five-star hotel in Halkidiki, one of the country’s top destinations, because she said conditions were so dire. Beyond the bad pay, the 22-year-old said that her working and living conditions were “miserable and unacceptable.” Millions holiday in Greece every year, but its vital tourism industry is finding it harder and harder to recruit Greeks to look after them. “I was asked to work in any department of the hotel where there was a need, from service to cleaning,” said Katerina, a tourism and marketing student, who would
i Gasoline and diesel prices at fuel stations are this week to rise NT$0.1 per liter, as tensions in the Middle East pushed crude oil prices higher last week, CPC Corp, Taiwan (台灣中油) and Formosa Petrochemical Corp (台塑石化) said yesterday. International crude oil prices last week rose for the third consecutive week due to an escalating conflict between Israel and Iran, as the market is concerned that the situation in the Middle East might affect crude oil supply, CPC and Formosa said in separate statements. Front-month Brent crude oil futures — the international oil benchmark — rose 3.75 percent to settle at US$77.01
