Komati Power Station

From Global Energy Monitor

The Komati Power Station is a 1,000-megwatt (MW) coal-fired station owned by the South African publicly-owned electricity utility Eskom that was mothballed in 1990 but later recommissioned.

Background

The Komati power station was built between 1961-1964 with nine units; units 1-5 of 100 MW each and units 6-9 of 125 MW each, totaling 1000 MW capacity. In 1988, three units at Komati were mothballed, one was kept in reserve, and the other five were only operated during peak hours. In 1990 the complete station was mothballed until 2008, when unit 9 was the first to be recommissioned under Eskom's return to service project.[1]

A total of 700 MW (4 units at 125 MW and 2 units at 100 MW) were commissioned by 2013. The final 3 units were planned to be recommissioned and commercially operational by 2014.[2] The last unit went into operation by July 2014.[3]

The units were recommissioned in the following years:[4]

  • Unit 9: December 2008
  • Unit 8: March 2009
  • Units 3 and 7: 2010
  • Unit 4: 2011
  • Unit 5: February 2012
  • Units 6 and 2: 2013[2]
  • Unit 1: 2014[2]


In April 2016 the Eskom Board said it approved the commencement of a pre-feasibility study for renewal options for four of its oldest power stations: Komati, Camden, Hendrina, and Arnot. The pre-feasibility study would take 18 months to complete, and would include looking at options such as plant life extension.[5]

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).[6]

In 2017, two older coal-fired units from Eskom's Grootvlei Power Station, one older unit from Eskom's Hendrina Power Station, and two older units from Eskom's Komati Power Station were placed into coal reserve because their running costs were higher than other units. A government spokesman said that the old stations were expected to remain uneconomical to run, even if refurbished, compared to renewable energy IPP power options and the company's newer stations at Medupi and Kusile.[7]

In 2019, it was reported the plant's nine units were planned for retirement in 2021.[8] However, in April 2020, Eskom listed the retirement dates for the units between 2024 and 2028.[9]

According to Eskom's 2020 Annual Report, all units at the power station except units 4 and 9 "have been placed in reserve storage or extended inoperability and their capacity removed from the nominal base... due to technical and/or financial constraints."[10]

Repurposing & Repowering Proposal

As of February 2021, Eskom was preparing a Request for Proposal for the repowering and repurposing of the Komati power station and was planning to launch bidding in Spring 2021. In 2021, social impact studies were completed for Eskom's Komati, Hendrina, Grootvlei, and Camden power stations to assess what impact the closure of the power stations would have on direct, indirect, and induced employment, as well as on large and small businesses in the areas surrounding the plants. The company also evaluated the various responses received to a request for expressions of interest for the repowering of the stations, using renewable-energy and storage solutions, or possibly switching their fuel sources to either gas or hydrogen. In addition, it received various repurposing proposals, ranging from the creation of training facilities to the development of agricultural activities on the sites.[11]

In April 2021, Eskom was still preparing the Request for Proposals. However, it signed a memorandum of understanding (MoU) with development financier Agence Française de Développement (AFD) that included a specific objective of creating a framework for cooperation and collaboration on Eskom’s evolving ‘just energy transition’ strategy. Eskom established a Just Energy Transition Office to oversee the repowering and repurposing, and the MoU makes specific reference to facilitating dialogue between the company and strategic stakeholders around the Komati power station. Eskom CEO Andre de Ruyter highlighted in a statement that Komati would be among those coal-fired power stations that it hoped to use as a showcase of a “more sustainable future under the just energy transition strategy”. He also noted that it was “non-negotiable” that the strategy of growing investment in renewable technologies at the sites be coupled with a positive impact on both the country’s electricity industry and on stimulating a local market and increased job creation in the country’s coal regions.[12]
