Power utility Eskom has shut down the coal-fired Komati Power Station and is looking to repurpose it for renewable energy.
In a statement yesterday, Eskom says after serving South Africa since 1961, the coal-fired Komati Power Station in Mpumalanga reached the end of its operating life and was shut down from midday.
Unit nine of the power plant was commissioned in March 1966, the last of nine units that were built. Other units were shut down over the years as they reached the end of their operating life, a legislated requirement, says the state-owned company.
According to the power utility, the shutting down of the plant will not have a significant impact on the national electricity grid as the remaining unit was only contributing 121MW.
Eskom has transferred the majority of Komati employees from the power station to support and augment skills in other power stations and areas of the business in line with operational requirements.
No Eskom employees will lose their jobs as a result of the closure, says the utility.
It adds the decommissioning of the power station has followed a diligent process, which comprised undertaking a socio-economic impact study.
Eskom says it held extensive engagements with employees, labour unions, the community and all affected stakeholders, and communicated the requirement to shut down the plant timeously and clearly with everyone involved.
The company notes Komati is one of the power stations that were previously mothballed due to the country’s excess generation capacity in the early 1980s, the age of the station and the high maintenance costs. Unit nine was then mothballed in 1989.
Subsequently, it says, a decision was made to return Komati Power Station to service, with the refurbishment commencing on 14 August 2006.
Unit nine was handed over to the generation division on 24 December 2008 and declared commercial on 4 January 2009.
Eskom has developed a just energy transition strategy which places equal importance on the “transition to lower carbon technologies” and the ability to do so in a manner that is “just” and sustainable.
The remaining employees will take part in the Komati Repowering and Repurposing project, it adds.
“The power plant will be converted into a renewable generation site powered with 150MW of solar, 70MW of wind and 150MW of storage batteries, thereby continuing to put the site and its associated transmission infrastructure to good use and provide economic opportunities to the community. A containerised micro-grid assembly factory has already been established on site,” Eskom says.
It points out that the development of the Komati Training Facility to facilitate the reskilling, retraining and upskilling of Eskom employees and members of the community, as appropriate, is under way.
Eskom has already signed a partnership agreement with the South African Renewable Energy Technology Centre of the Cape Peninsula University of Technology, and the Global Energy Alliance for People and Planet to develop the training facility.
Funding for this facility, which will enable a “just” transition for the local community following the decommissioning of the power station, has already been received from one of the developmental finance institutions and Eskom will make an official announcement in due course, the company says.
It explains the Komati Repowering and Repurposing project is one of the largest coal-fired power plant decommissioning, repowering and repurposing projects globally, and will serve as a global reference on how to transition fossil-fuel assets.
