Coal reserves are estimated at 53 billion tonnes. It was an open bid where all the key suppliers were asked to submit a company profile and describe their capabilities in supercritical technology. The steam passes the main valves and is then fed directly into the blading path. Site activities are under the control of Eskom, the first equipment erected by Alstom on site being the air-cooled condenser. In a statement the board said the unreliability of Medupi and Kusile was a “serious concern”. In terms of arrangement, Medupi and Kusile’s optimised design has the steam turbine generator set at low level, with the turbine axis at 10 m and lateral exhaust LP casings. GE trained and qualified over 850 trade professionals and funded students and spent more than 18BN ZAR on local content for both the Medupi and Kusile projects. The ACC is also of a different design since Alstom has sub-contracted the design, manufacture, supply and erection of the ACCs for Kusile to DB Technologies, an SPX company. The outer casing is assembled by means of hydraulically tightened expansion bolts. On Monday, Eskom unexpectedly increased the intensity of nation-wide power cuts from stage two, which requires that 2 000 megawatts of power be rotationally cut from the system, to stage four, which requires cuts of 4 000 megawatts. In particular Kusile will have South Africa’s first flue gas desuphurisation (FGD) system (in the tendering process at the time of writing). GEA will also supply the entire steel structure including the supporting steel structure and fan deck, fan rings, the wind walls on the fan deck, the steam duct, the condensate, air and steam piping and the electrical controls. Medupi and Kusile, expected to be among the world’s biggest coal-fired stations, share the same configuration. Medupi and Kusile, expected to be among the world’s biggest coal-fired stations, share the same configuration. In a presentation given to the portfolio committee on public enterprises, the department detailed how costs to build Medupi and Kusile have increased by more than R300-billion — reaching R145-billion for Medupi and R161.4-billion for Kusile. Kusile is a coal-fired power station close to the existing Kendal power station in the Delmas municipal area of the Mpumalanga province South Africa. Under these contracts, each worth more than r1 billion, Alstom is responsible for the supply of the steam turbines, generators, associated air cooled condensers (subcontracted to GEA for Medupi and to SPX for Kusile), related turbine island auxiliary equipment and feedwater heating plants. Alstom is also responsible for the turbine hall cranes, valve piping and local instrumentation, ventilation and fire protection. The Medupi–Marang transmission line will call for the construction of a 400 kV transmission line of some 300 km in length from the Medupi substation near Lephalale to the Marang substation near Rustenburg (North West Province) as well as the construction of a 400 kV transformer bay at the Medupi substation and a 400 kV feeder bay at the Marang substation. Medupi and Kusile, at 4,800MW each, are to be among the biggest coal-fired stations in the world. “They are of the wrong design. Interference. Steam for feedwater heating is extracted at certain points along the blade path. Company Information. As a rule, a coal-fired power station takes about eight years to build. This is a typical Eskom approach, where the company takes on the role of integrating the packages, effectively taking on the role of architect engineer. Introduction Eskom has embarked on a process of developing two very large coal-fired power stations, namely Medupi and Kusile. The initial investment decision for the project was made in 2005. The adjudication process lasted for most of 2007. The building of this power station attracted various criticisms. This is in Mpumalanga province, 140 km east of Johannesburg and just a few kilometres north of the site of the existing Kendal power station. Medupi and Kusile are multi-contract projects, with Eskom awarding the contract in a number of packages. The Medupi–Dinaledi transmission line requires the construction of two 400 kV transmission lines of approximately 350 km between the Medupi substation, the Spitskop substation near Northam (Limpopo province) and the Dinaledi substation near Brits (North West Province) as well as the construction of two 400 kV transformer bays at Medupi substation, four 400 kV feeder bays and two 400 kV lines at Spitskop substation, and two 400 kV feeder bays at Dinaledi substation. This resulted in a dwindling reserve margin, which fell from about 20% to less than 10%. Medupi and Kusile, expected to be among the world’s biggest coal-fired stations, share the same configuration. This is according to Public Enterprises Minister Pravin Gordhan, who told parliamentarians on Wednesday that Medupi and Kusile were supposed to provide “the extra energy space” to allow old units to be taken down for repairs. LETTER: Don’t let Valli Moosa’s praise of party funding act fool you. Medupi and Kusile are the fourth-largest coal-fired power stations in the world and serve as benchmarks for what MHPS is capable of building. Instead, it stated that it faced “liquidity challenges”. GDP growth in 2009 is forecast to be around 1.2%. About 77% of the country’s primary energy needs are provided by coal, a situation that is unlikely to change significantly over the next decade. The Medupi and Kusile power stations were constructed to increase the electricity generation capacity of South Africa. The parting plane of the outer casing is horizontal at the level of the rotor axis. With Eskom being a public sector company, it one of South Africa’s largest ever public sector projects. At Medupi Unit 6, the first of the new units to be completed, this handover period was nine months. Share on Facebook Share on Twitter. During the 1970s and 80s the naming convention changed to indigenous words related to the generation of electricity. Eskom also recently concluded a R15-billion loan from a consortium of banks geared towards funding its capital expenditure programme. For Medupi, Alstom received a first expression of interest in late 2005. The site measures 2500 ha and was previously used for game and cattle grazing. More than 3,300 GE professionals—direct employees and subcontractor—are working every day onsite at the Kusile power plant to ensure its on-time construction and delivery. The inner casing is mainly assembled by means of shrink rings. There is a condensate feed extraction pump with a 1 x 100% variable frequency drive plus 1 x 100% fixed speed drive. Kusile’s initial cost was put at R100 billion, but it will now cost R161.4 billion.Last year the conveyor belt that is meant to transport coal from the Grootegeluk Mine to Medupi broke down, leaving the power station without coal and plunging the country into stage six load shedding. Here is a breakdown of both: **Medupi** – Medupi is a coal-powered power plant in Lephalale in Limpopo. Steam flow at nominal load is 617 kg/s. The inner casing carries the stationary blading. Parliament's Standing Committee on Public Accounts has reported on its findings, following a two-day visit to the Medupi and Kusile power stations. South Africa’s freshwater fish face extinction. The coal will therefore probably need some washing before being burned in the plant. The coal for the power plant will be sourced from Exxaro Coal's Exxaro said it would spend Rand 9 billion ($1.10 billion) on an expansion of its Grootegeluk mine in the north of South Africa in order to meet the new demand from Eskom. Lynley is a senior business reporter at the Mail & Guardian. The programme includes: installation of open cycle gas turbine power plants for meeting peak demand; a return to service of power stations; an increase in generation by improving operating performance; and the addition of new baseload capacity. Priority will thus be given to previously disadvantaged groups in all jobs created. GE trained and qualified over 850 trade professionals and funded students and spent more than 18BN ZAR on local content for both the Medupi and Kusile projects. Moosa negotiated with Hitachi for the supply of boilers to Eskom’s new power stations at Medupi and Kusile, which made the ANC a large profit. Flange bolts are only used at the inlet section. Log in to Reply The Navigator 2 years … The remainder of the country’s coal production is used internally, with 53% used for electricity generation. Medupi and Kusile, which will be among the largest coal power stations in the world when complete, have been beset by delays and faults that have hobbled their electricity output. period 2009-2012. Deputy president David Mabuza says Eskom has committed to completing the construction of Medupi power station this year, while Kusile will be completed by 2023. In the case of Medupi, which has three units — units six, five and four — in commercial operation, unit six did not operate during September, October and November last year. This has resulted in years of rolling blackouts. Other steps to fight climate change include improved reporting, monitoring and laws, The ANC’s regional secretary in the Amathole is at the head of an alleged scheme to fundraise for his party, Lord’s Resistance Army leader found guilty of forced pregnancy charges in landmark case. Nevertheless the reserve margin is not expected to get above the current low level until 2012, when Medupi and Kusile come on line. Medupi is located next to the Matimba power station, 15 km west of Lephalale, in the Limpopo province of South Africa. The schedule for the Kusile project is the same as Medupi but about one year later. These structures included the 12,5 MVA Service Transformers and the Condensate Polishing Plants for Medupi Units 1 to 6, and the Water Treatment Plant for Kusile. new plants, Kusile and Medupi, are already under construction and will be the third and fourth largest power plants in the world. But, said Yelland, even these estimates may now be too low, because the cost of retrofitting Medupi for FGD, for instance, is believed to have doubled since 2016. Home Currently selected. The problems at Medupi and Kusile intensify the long-standing challenges of the upkeep of Eskom’s fleet. The condenser modules consist of galvanised air-cooled condenser tubes, tube sheets and the steam and condensate collection headers. The Medupi power plant will consist of 6 units delivering 800MW each for a total of 4,800MW. The decision to build Medupi and Kusile was taken in a crisis behind closed doors when Eskom refused in 2005 to implement government policy...to build independent power producers. Medupi and Kusile have been under construction since 2007 and 2008 respectively, and are planned for completion in 2020 and 2022, and shown in Fig. But so far South Africa’s indigenous industry is coping and seems up to the task of delivering the skills and equipment required to bring these giant projects in on time. The design is done only once, except for some site specific items arising from the different altitude and coal specifications (fan dimensions, economiser surface area, foundation design). After expansion the steam is exhausted horizontally to the air cooled condenser. Eskom will launch an urgent review to establish when “these projects will be completed, the extent of design and other operational faults, what steps can be implemented to minimise the ever-escalating costs and what can be done to increase output”, it said. Medupi and Kusile, which will be among the largest coal power stations in the world when complete, have been beset by delays and faults that have hobbled their electricity output. In the face of severe power shortages, in 2007 South Africa’s state-owned utility, Eskom awarded contracts for two identical coal fired plants. Eskom has quietly extended the target dates for the Medupi and Kusile power stations to be fully operational, by a year. Major industry has already begun to feeling the effects of load-shedding. The units at Medupi and Kusile that have been put into commercial operation are “some of the worst-performing units in the fleet”, said Yelland. It is the second most advanced coal-fired power plant project in Eskom after Medupi power station in Lephalale. The generator features a re-tightenable end-winding that simplifies maintenance and increases the generator’s availability. Local skills will be developed through training people as managers and technicians. Alstom has completed a major portion of the equipment design and purchased a major portion of the equipment. Around 80% of all turbines in operation in South Africa are Alstom-designed and the company currently employs over 5000 people to meet new power project commitments, and aiming to recruit hundreds more. Kusile is a largely similar, 6 x 800 MW station located in the industrialised Witbank area, in Mpumalanga Province, to the east of Johannesburg. This results in sustained efficiency over the long term and lower operational costs. The shortage of water in South Africa dictates the use of air-cooled condensers (ACC) at Medupi and Kusile. As a rule, a coal-fired power station takes about eight years to build. function loadDoc() {var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { document.getElementById("pressoffice").innerHTML = this.responseText; }}; xhttp.open("GET", "https://mg.co.za/scripts/rss/pressofficeServer.php?menu=false&items=5&feed=http://pressoffice.mg.co.za/feed/rss2.php", true); xhttp.send();} loadDoc(); For all the latest information and advice from the Department of Health relating to Covid-19, please visit sacoronavirus.co.za. The massive cost and time overruns at Eskom’s Medupi and Kusile power stations will place upward pressure on Eskom’s electricity price trajectory in the years ahead, states Chris Yelland. The office has grown since its establishment in September 2007 and now employs around 120 people, with about 95% of staff within the execution centre being locals. Gordhan told MPs that Eskom’s board, management and government are working to ensure that this period of “severe load-shedding is as short as possible”. Looking to the future, the company has developed an integrated electricity plan to greatly boost the country’s installed capacity, from the current level of around 39 GW, with a comprehensive strategy, to reduce the risk of power shortages over the. Medupi and Kusile, expected to be among the world’s biggest coal-fired stations, share the same configuration. The convention has been refined with Eskom contracting independent researchers to examine the history of the areas in which new projects are planned, and to identify names that reflect the cultural heritage of the area. At Medupi Unit 6, the first of the new units to be completed, this handover period was nine months. The department of public enterprises caused consternation on Wednesday after its presentation in Parliament, which stated that Eskom was “technically insolvent” and, based on its current trajectory, would “cease to exist” by April. The two main power plants currently under construction are Medupi and Kusile. Its two-plate design also allows it to deliver reactive power to the grid for stabilisation in the event of a disturbance. At two subsequent units, with the first completed at Kusile, it was shorter. Claims against Eskom. A third of our freshwater fish are dying out due to climate change and invasive species. A triple circuit hydrogen sealing system is used instead of a double circuit system, which keeps the hydrogen at very high purity levels and reduces the consumption of hydrogen. please consider taking out a subscription, Like Molefe, Singh tells Zondo commission ‘bags of money’ story is all lies, South Africa to get another commission, this one to tackle the climate crisis, Zondo deplores ‘attempted killing’ of state capture witness who implicated Molefe, Zondo commission: Glencore sold Optimum to portray me as a Gupta ally — Molefe, Koko maintains he had no idea he was exchanging emails with a man likely to be Salim Essa, Mabuyane targeted in Eastern Cape road debacle, LRA’s Ongwen: A critical first ICC conviction. Rework and unauthorised expenditure at Medupi and Kusile since 31 Mar 2016. Excavations have been completed and foundation works for the turbine hall are ongoing. 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. The Notice to Proceed was finally given on 1 October 2007 and the contract signed in November. Kusile and Medupi power stations continue to come under fire as poorly managed and ill-designed, remaining years behind completion dates amid … On Monday the minister met the Eskom board and management after seven units unexpectedly tripped, including a reported two units at Medupi, precipitating the stage four load-shedding. For Medupi, Alstom received a first expression of interest in late 2005. Business Vision; Eskom Enterprises; Eskom Heritage; Ethical Business Conduct; Legislation; Application for an Electricity Generation License The current record is held by the 3600 MW Matimba power station. The inner casing is of cast design. The 4764MW Medupi coal-fired power station, situated near Lephalale in Limpopo province, has been under construction since 2007. This scenario is likely to last until March 4, according to the report, which has yet to be updated. Gordhan said Eskom was making efforts to contact people who have left South Africa in recent years, in a bid to bring this expertise back home. Chris Yelland Eskom Headline Scopa. After passing the crossover pipe the steam enters equally into the two LP casings, with a double-flow configuration. It is axially flexible to allow thermal expansion but is rigid in the radial and tangential directions so that it can withstand high electromagnetic forces. Medupi and Kusile are a disgusting monument to the incompetency and corruption so endemic to the Zuma era. The latter’s two towering smokestacks and six … The crisis at Kusile and Medupi continues … Eskom is expected to announce a bottom-line loss for the year in the region of R25bn. The dates were spotted by … This is a typical Eskom approach, where the company takes on the role of integrating the packages, effectively taking on the role of architect engineer. A wide range of mechanical and electrical skills will be transferred to local industry through a period of three to four years of training in such fields as design, building, maintenance and electrical technology. Eskom has also awarded contrac ts Keywords: climate change, Medupi, Kusile, oppor-tunity cost 1.
