Background
Kriel power station is a six-unit coal-fired power plant with a total capacity of 3,000 MW. The plant was completed between 1976 and 1979, and is owned by Eskom.
In October 2021, the Department of Forestry, Fisheries and the Environment partially granted an environmental compliance postponement application for the power station.[2]
In their 2021 Integrated Report, Eskom noted coal quality and contamination issues at the plant. Additionally, high levels of particulate and dust emissions were an ongoing issue. Regardless, the plant remains online through "periods of poor performance".[3]
Incidents
Units at the plant face frequent disruptions. For example, in May 2021, a unit went offline due to a boiler tube leak contributing to loadshedding.[4]
In May 2022, arrests were made in relation to a "sophisticated crime syndicate in cahoots with Eskom officials, police and trucking companies" who had apparently siphoned and stolen millions of rands worth of fuel at the Kriel power station. According to investigative journalists on the ground, this has been going on undetected for several years, exploiting a design flaw in the plant's weigh bridge. Eskom did not provide an explanation for why the discrepancy between delivered volume and consumed volume was not caught.[5]
In July 2022, electrical faults took five units offline at the power station, contributing to ongoing loadshedding problems on the Eskom grid.[6] In September 2022, a conveyor belt that moves coal from the Kriel mine to the power station caught fire. An investigation was underway to assess the damages.[7]
In April 2023, a former finance manager at the Kriel power station had been convicted of fraud and theft of more than R500,000 (US$25,900).[8]
In November 2024, hydraulic oil from a broken pipe leaked onto a turbine at Unit 6 and caught fire. Eskom did not expect lost generation from the damaged unit to lead to loadshedding.[9]
Retirement plans
In March 2017, Eskom said that it would hold meetings with the government and labour to discuss its plans to decommission five power stations over the next five years: Komati Power Station, Hendrina Power Station, Kriel Power Station, Grootvlei Power Station, and Camden Power Station. Eskom said the stations are old and unneeded, given the country's plans for new power capacity by independent power producers (IPPs).[10]
However, according to South Africa's 2019 Integrated Resource Plan, the plant's 50-year Life Decommissioning was projected for 2026-2029.[11] And in April 2020, Eskom listed the planned retirement dates for the plant's six units between 2026 and 2030.[12]
In November 2020, the World Bank Group invited expressions of interest from consultants to assess the implications of retiring the Camden, Hendrina, Grootvlei, and Komati coal plants, but not the Kriel power station.[13]
As of October 2023, the South African government was reviewing their 2019 Integrated Resource Plan (IRP) and expecting to release an updated IRP before the end of the year. During the review, it was reportedly proposed that coal plant decommissioning dates scheduled for before 2030 be pushed back until 2030 and later.[14] A study by the Centre for Research on Energy and Clean Air (CREA) published in October 2023 estimated that postponing the decommissioning until after 2030 would cause 15,300 excess air pollution-related deaths.[14]
In May 2024, it was reported that Eskom planned to delay the closure of several coal units in an effort to alleviate the country's electricity crisis. The utility reportedly said that "although there are no new formally approved shutdown dates for the older stations," coal units that were scheduled to close between 2023 and 2030 were now "expected to run until 2030."[15]
Environmental impact
A 2019 Greenpeace report found that Kriel in Mpumalanga was the second worst sulphur dioxide (SO2) pollution hotspot in the world.[16]
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.[17]
According to a March 2024 report on air pollution in Africa by Greenpeace, Kriel power station and Matla power station were Africa's two largest point sources of nitrogen oxide (NOx) pollution from May 2018 to November 2021. Another seven Eskom coal plants appeared in the report's list of the ten largest NOx emissions hotspots in Africa for that period. Kriel also topped the list of Africa's largest point sources of sulfur dioxide (SO2) pollution in 2022, along with Duvha power station and Kendal power station. Three additional Eskom coal plants appeared in the top ten SO2 emissions hotspots in Africa in 2022. The report noted that government data on emissions in Africa is patchy, so the authors relied on satellite measurements.[18]
In May 2024, South Africa's Ministry of Forestry, Fisheries and the Environment approved an exemption for Hendrina power station, Kriel power station, Grootvlei power station, Camden power station, and Arnot power station from a 2010 sulphur dioxide emissions control rule. The power stations were authorized to operate through 2030 without meeting the standard. In June 2024, Eskom indicated that it intended to apply for exemptions for Matla power station, Duvha power station, Tutuka power station, and Kendal power station as well.[19]
