Background
Matimba power station is a six-unit coal-fired power plant with a total capacity of 3,990 MW. The plant was completed between 1987 and 1991, and is owned by Eskom.[1]
According to a 2018 case study, the adjacent Grootegeluk coal mine has sufficient coal reserves to guarantee Matimba a minimum lifespan of 35 years, extending to a possible 50 years at 2,100 - 2,130 tons of coal per hour.[2] Another 2020 article found that at the current rate of production, the open pit mine has enough coal for the next 125 years.[3]
The plant has been described as follows: "Compared with the national angst about Medupi power station’s frequent outages and design flaws, Matimba is downright boring: it simply burns coal and produces carbon dioxide, over and over again, and will do so for decades to come."[3]
In October 2021, the Department of Forestry, Fisheries and the Environment denied Eskom's request for environmental compliance postponement for the power station.[4] Eskom appealed the decision and claimed that, if implemented, it "would have a significant negative impact on the economy and employment … and delay the country’s plans for an energy transition to a cleaner energy supply.”[5]
According to South Africa's 2019 Integrated Resource Plan, the plant's 50-year Life Decommissioning is projected for 2037-2041.[6] In April 2020, Eskom listed the unit retirement dates between 2038 and 2042.[7]
In June 2022, a unit at the Matimba power station tripped. The break down contributed to Stage 2 loadshedding and the ongoing vulnerability of Eskom's grid.[8]
In March 2023, it was reported that maintenance on Unit 5 could be delayed due to a strike by 147 employees of a company subcontracted by Eskom to perform repairs on equipment.[9]
In August 2023, two units at the power station were taken offline for repairs. Eskom announced Stage 4 load shedding amid a country-wide loss of generation capacity.[10]
Sabotage investigation
In late 2021, three of its units went down simultaneously after technicians dropped an extension cord onto the unit 2 transformer. Eskom CEO André de Ruyter – who had earlier shared that criminal elements were attempting to sabotage the power utility – explained that a team had been working on the station’s dry cooling fans when they dropped the cord. This caused a flash, which tripped the station board and shut down all cooling to units 1, 2, and 3, leading to all three shutting down.[11][12]
Environmental impact
In September 2023, Reuters published an analysis showing that four Eskom power stations — Kriel power station, Matimba power station, Matla power station, and Kendal power station — had breached regulations for particulate matter emissions in the prior year.[13]
According to a March 2024 report on air pollution in Africa by Greenpeace, Matimba power station was among Africa's ten largest point sources of nitrogen oxide (NOx) pollution from May 2018 to November 2021. Eight other Eskom coal plants were included in the top ten NOx emissions hotspots in Africa for that period. Matimba power station was also among the top ten sulfur dioxide (SO2) emitters in Africa in 2022, along with five other Eskom coal plants. The report noted that government data on emissions in Africa is patchy, so the authors relied on satellite measurements.[14]
