  • Orange River Project
    ORANGE RIVER PROJECT: OvERVIEW South Africa NAMIBIA BOTSWANA Orange-Senqu River Basin Vanderkloof Dam LESOTHO Gariep Dam LOCATION SOUTH AFRICA The Orange River Project (ORP) is the largest scheme in the Orange–Senqu River basin, and includes the two largest dams in South Africa, the Gariep and Vanderkloof. They regulate flows to the Orange River and increase assurance of supply. DESCRIPTION Gariep and Vanderkloof dams were constructed as part of the project, and have a combined storage of 8,500 million m3. The ORP includes several sub-systems. The Orange–Riet Water Scheme.* The Orange–Fish Transfer Tunnel.* The Orange–Vaal Transfer Scheme.* Bloem Water: Pipeline network between Gariep Dam and the towns of Trompsburg, Springfontein and Philippolis. Irrigation abstractions: Between Gariep Dam and downstream of Vanderkloof Dam, up to the confluence of the Vaal and Orange rivers (near the town of Marksdrift). Urban and industrial abstractions: Between Gariep Dam and Marksdrift (including Hopetown and Vanderkloof towns). Support to the Lower Orange Water Management Area Schemes: * Support to most of the demands in the Gariep Dam (© Hendrik van den Berg/Panoramio.com) Lower Orange, including irrigation, urban use and power generation. Caledon–Bloemfontein Government Water Scheme.* * Further details are given on separate pages PURPOSE The purpose of this very complex scheme is to supply demands within several sub-systems, including the Upper and Lower Orange water management areas all the way down to the Orange River mouth, and the Eastern Cape Province. These demands include irrigation, urban, industrial and environmental water requirements. Power generation is also part of the system, including at Gariep and Vanderkloof dams, which contributes to the Eskom national power grid.

  • Maximising Hydro-Power Generation Within a Multi-User Water Supply System
    226 Hydrocomplexity: New Tools for Solving Wicked Water Problems Kovacs Colloquium, July 2010 (IAHS Publ. 338, 2010) Maximising hydro-power generation within a multi-user water supply system L. BAPELA1, B. MWAKA1, R. CAI1 & H. G. MARÉ2 1 Department of Water Affairs and Forestry, South Africa [email protected] 2 WRP Consulting Engineers (Pty) Ltd, South Africa INTRODUCTION In order to optimise the generation of hydro-power from Gariep and Vanderkloof dams, and to supply the other water users at the required risk levels, a system utilisation agreement was formed between the Department of Water Affairs (DWA) of the Republic of South Africa (RSA) and Eskom (the national energy supplier within the RSA). As part of the agreement between DWA and Eskom, DWA commissioned the Orange River System Annual Operating Analysis study to ensure that all the users are supplied at the required assurance and to determine the volume of water available for the generation of hydro power on an annual basis. Background Gariep and Vanderkloof dams are the two largest dams in the RSA, located in the Orange River, with gross storages of 5343 million m3 and 3187 million m3, respectively. Several water supply sub-systems, including the well known Lesotho Highlands Water Project (LHWP), are located upstream of Gariep and Vanderkloof dams. These sub-systems, some with large transfers, all have an effect on the water availability in Gariep and Vanderkloof dams, also referred to the as the Orange River Project (ORP). The total 2008 demand imposed on the ORP is in the order of 3200 million m3/year-1 and is just lower than the historic firm yield of 3 349 million m3/year-1.

  • Hydro Energy Hydroelectric Power Hydro Energy
    Hydro Energy Hydroelectric Power Hydro Energy • Hydroelectric power refers to the generation of electric power through the extraction of energy from moving water streams. • A large fraction of radiation reaching the Earth’s surface is absorbed by the oceans, warming them and adding water vapour to the air. Source: Unsplash.com • The water vapour condenses as rain to feed rivers in which dams can be built and hydroelectric turbines installed to extract the energy of the flowing water. • Moving water can be extremely powerful. • The kinetic energy of flowing water can be used to drive hydroelectric turbines to produce electricity. Source: pixabay.com 2 Hydroelectric Power Hydroelectric Power: Hydro Energy Converted To Electricity • Gravity makes water flow from a high to a low place. The moving water contains kinetic energy. Hydroelectric Dam • Hydroelectric power stations are able to transform the kinetic energy in moving water to electrical energy. • In a hydroelectric power station, part of a river’s flow is sent through pipes. • The water then turns the turbines, and the turbines turn the electricity generators. • The water is returned to the river further downstream. • In the conventional system, water is stored behind a dam wall. • The power station is normally situated close to the dam wall. • The water is released on demand, powering huge turbines that generate electricity. 3 Hydroelectric Power Hydroelectric Power in SA • Eskom operates hydroelectric power stations at both the Gariep Dam and the Vanderkloof Dam. • In South Africa, the most important role of these power stations is the storage of ‘electricity’ in case of unexpected demand, or in case of sudden operational disturbances at one of the power stations supplying the regular demand.

  • Mercury Emissions from South Africa's Coal-Fired Power Stations
    Mercury emissions from South Africa’s coal-fired power stations Belinda L. Garnham*1 and Kristy E. Langerman1 1Eskom Holdings SOC Limited, Megawatt Park, 1Maxwell Drive, Sunninghill, Sandton, [email protected], [email protected] Received: 8 August 2016 - Reviewed: 3 October 2016 - Accepted: 2 November 2016 http://dx.doi.org/10.17159/2410-972X/2016/v26n2a8 Abstract Mercury is a persistent and toxic substance that can be bio-accumulated in the food chain. Natural and anthropogenic sources con- tribute to the mercury emitted in the atmosphere. Eskom’s coal-fired power stations in South Africa contributed just under 93% of the total electricity produced in 2015 (Eskom 2016). Trace amounts of mercury can be found in coal, mostly combined with sulphur, and can be released into the atmosphere upon combustion. Coal-fired electricity generation plants are the highest contributors to mer- cury emissions in South Africa. A major factor affecting the amount of mercury emitted into the atmosphere is the type and efficiency of emission abatement equipment at a power station. Eskom employs particulate emission control technology at all its coal-fired power stations, and new power stations will also have sulphur dioxide abatement technology. A co-beneficial reduction of mercury emissions exists as a result of emission control technology. The amount of mercury emitted from each of Eskom’s coal-fired power stations is calculated, based on the amount of coal burnt and the mercury content in the coal. Emission Reduction Factors (ERF’s) from two sources are taken into consideration to reflect the co-benefit received from the emission control technologies at the stations.
