  • Eskom's Financial Crisis and the Viability of Coal-Fired Power in South
    ESKOM’S FINANCIAL CRISIS AND THE VIABILITY OF COAL-FIRED POWER IN SOUTH AFRICA IMPLICATIONS FOR KUSILE AND THE OLDER COAL-FIRED POWER STATIONS Grové Steyn, Jesse Burton, Marco Steenkamp Contact: [email protected] 15 November 2017 ACKNOWLEDGEMENTS This study benefitted from the support of numerous parties. It was funded by a grant from the European Climate Foundation. We acknowledge the support from the Institute for Energy Economics and Financial Analysis (IEEFA) and, in particular our collaboration with David Schlissel. We also acknowledge the role of a wide range of stakeholders and industry participants who granted us interviews and without whose support we would not have been able to undertake the project.1 We thank the Council for Scientific and Industrial Research (CSIR) Energy Centre for undertaking the system level analysis for this project.

  • Enviroserv Chloorkop Landfill Site Expansion Project Wetland, Soil and Land Capability Specialist Study Report
    ENVIROSERV CHLOORKOP LANDFILL SITE EXPANSION PROJECT WETLAND, SOIL AND LAND CAPABILITY SPECIALIST STUDY REPORT Report No.: JW100/19/6007-25 May 2019 Internet presence: www.jaws.co.za Synopsis EnviroServ Waste Management (Pty) Ltd own the existing Chloorkop Landfill Site (CLS) and operate it in terms of a waste management licence (Ref: 16/2/7/A230/D17/Z1). Municipal solid waste is received from the Midrand area, including the City of Johannesburg and the Ekurhuleni Metropolitan Municipality. The CLS is located in the Chloorkop Industrial area on Portion 63 of Klipfontein 12-IR and is accessed from Marsala Road. The waste body at the CLS has finite airspace, defined by the permitted footprint, height and design parameters and will not be able to receive waste once it reaches airspace capacity. EnviroServ is proposing to expand the CLS in order to provide additional airspace for ongoing disposal of municipal solid waste. The proposal is to expand the Chloorkop Landfill Site onto adjacent properties (Erf 334 and 335 of Chloorkop Extension 6), CLS Expansion Project. The concept is to establish engineered, Class B waste disposal cells on the target properties for ongoing disposal of municipal solid waste. The additional waste disposal cells would join with the current CLS waste body. The facility will include a small Material Recovery Facility for the separation of clean recyclables from the waste. Supporting infrastructure would be integrated with the CLS and/or redeveloped as appropriate. A municipal road, Anker Street, separates part of the expansion area from the CLS and thus a phased approach is likely.

  • Technical Tour To: Kusile Power Station Eskom, Witbank - South Africa, 4 October 2019
    Technical Tour to: Kusile Power Station Eskom, Witbank - South Africa, 4 October 2019 Kusile Power Station Technical Visit and Tour Shuttle bus from Misty Hills Country Hotel, 69 Drift Blvd, Muldersdrift, Johannesburg, South African , at 06:30 on Friday 4 October 2019 Return via shuttle bus by 14:00 Register from registration page Kusile Power Station Kusile is a coal-fired power station close to the existing Kendal Power Station in the NKANGALA DISTRICT of the Mpumalanga Province. The Kusile site is about 1 355 hectares in size, and is located on the Hartbeesfontein and Klipfontein farms. Kusile is the most advanced coal-fired power plant project in Eskom after Medupi power station in Lephalale where construction commenced in 2007. The station will consist of six units each rated at approximately 800 MW installed capacity giving a total of 4800 MW. As such it will be one of the largest coal-fired power stations in the world, once finished. The power station will be coal fired, with the coal supplied by Anglo Coal (New Largo and Zondagfontein collieries). The combination of the resources is expected to yield not less than 800 million sales tons over a period of not less than 47 years. Kusile will be the first power station in South Africa to have Flue Gas Desulphurization (FGD) installed. FGD is the current state-of-the art technology used to remove oxides of sulphur (SOx), e.g. sulphur dioxide (SO2), from the exhaust flue gases in power plants that burn coal or oil. This technology is fitted as an atmospheric emmission abatement technology, in line with current international practice, to ensure compliance with air quality standards, especially since the power station is located in a priority airshed.
