Kusile Power Station (formerly known as the Bravo Power Station) in South Africa is a coal-fired power plant under construction by state electricity utility Eskom.

Location

Located about 15 kilometres north of the existing Kendal Power Station near Witbank, Mpumalanga.

Original Concept

Kusile Power Station is designed to consist of six 800 megawatt coal-fired generating units for a total generating capacity of 4,800 megawatts.[1] This station would be the first in Eskom's fleet with flue gas desulphurization technology.

Project Engineer

Black and Veatch was appointed as the project engineer for construction.

Main equipment suppliers

Alstom provided the steam turbines, whilst Hitachi would provide the super critical boilers.

Coal supply

The power utility, Eskom stated that it "will obtain most of the coal required for this Power Station from Anglo Coal's New Largo operations, south east of the Kusile Power Station."[2]

Eskom's consultants estimate that 35 new coal mines will be required to support the Medupi and Kusile plants.[3]

Construction timeline

Initially expected to take 6 years to complete, the project was not expected to complete Unit 1 until 2017 (approximately 8 years after initial works began) and the entire project not until 2021.[4]

  • 5 June 2007: Department of Environmental Affairs & Tourism issued a positive Record of Decision.[5]
  • February 2008: Hitachi Power Africa awarded the boiler contract worth R18.5 billion. "[6]
  • February 2008: Alstom S&E awarded the turbine island works contract valued at R13 billion. "[6]
  • 14 April 2011: Black & Veatch Corp. Awarded approval for $805.6 million in financing from the U.S. Export-Import Bank.[7][8]
  • 31 May 2011:Export-Import Bank of the United States approves $805 million (R5.78 billion) loan.
  • October 2014: 300 ton 910 MVA Generator Step-up Transformer placed on its foundation, assembled with all its Auxiliary systems and filled with 128 000 Litres of Mineral Oil. All Electrical integrity tests were performed successfully to confirm that the transformer was ready to receive power.
  • 10 March 2017: Unit 1 achieves commercial power.[9]
  • 7 July 2017: Unit 2 was synchronised to the national grid.
  • 16 March 2019: Unit 3 was synchronised to the national grid.[10]
  • 30 October 2020: Unit 2 reaches commercial operation.[11]
  • 31 March 2021: Unit 3 reaches commercial operation.[12]
  • 23 December 2021: Unit 4 connected to the national grid.[13][14]
  • 31 May 2022: Unit 4 reaches commercial operation[15]

Delays and defects

The dates for full commercial operation were shifted numerous times mostly due to:

  • Labour disputes:
    • May 2011: Eleven contractor vehicles, seven offices, two large mobile cranes, and the west wing of the KCW office block were set alight, vehicles stoned, and offices and stores looted.[16]
    • February 2014: 1400 employees reported absent.[17]
    • 10 August 2018: A fire breaks out at the station amidst tensions with unions over pay increases causing damage.[18]
  • Technical issues such as:
    • Boiler design: high temperatures that the spray water-cooling system could not cope with [19]
    • Fabric filter plant: excessive wear of bags, resulting in blockages [19]
    • Coal mills: not meeting operational requirements, therefore requiring a doubling of servicing [19]

This resulted in Kusile and Medupi considered as some of the worst-performing units in Eskom's fleet.[19] In February 2019, Eskom GM for group technology Titus Mathe reported R8 billion would be needed to fix design defects at Medupi and Kusile.[20]

Critics

The building of this power station attracted various criticisms.

Interference

Hitachi Power Africa, a subsidiary of Hitachi, Ltd., found by the U.S. Securities and Exchange Commission to have made US$6 million in corrupt payments to Chancellor House, a front company for the African National Congress, the ruling political party in South Africa.[21] Hitachi agreed to pay US$19 million to settle charges.[21] Hitachi Power Africa rebranded as Mitsubishi Hitachi Power Systems Africa in February 2014.[22]

Cost

Kusile Power Station is estimated to cost R118 billion to complete.[4]

Financial Institution Support

The following institutions were involved in supporting the project:[23]

Emissions

The plant is expected to emit est 36.8 million tonnes of CO2-equivalent per year once completed.[24]

In November 2011, Greenpeace activists chained themselves to a gate and climbed a crane, a few weeks before the country hosted a global conference on climate change. Authorities arrested nine people, on charges of trespassing and malicious damage to property.[25]

The design of the station does allow for the installation of flue gas desulphurization technology, the first of its kind in South Africa.

Inquiry

By 2018, the governments Public Enterprises Minister Pravin Gordhan announced a forensic probe into delays and cost overruns on the completion of Kusile and Medupi Control Stations.[26]

Corruption controversy

In November 2019 South African investigative journalist Pieter-Louis Myburgh published an article in the Daily Maverick detailing an alleged slush fund corruption scandal involving Eskom executives and at least four contractors.[27] The scandal involved contracts worth a combined R10 billion resulting in an estimated R75 million being lost due to irregular activities.[27] By the time of the publication of Myburgh's article the construction of Kusile was five years past its original completion date and an estimated R80 billion (equivalent to US$5.4 billion) over budget.[27]
