Eskom December 09 www. bus- ex. com 65 in 20 years, it will also be the fourth largest coal plant in the world and the largest dry- cooled power station to be built globally. Highly advanced, the boilers at the new power station will be using super critical plant technology, meaning they will operate at higher temperatures and pressures than previous boilers, therefore performing more efficiently and consuming less water and coal. The site for this prestigious project was carefully chosen. Thorough screening and feasibility studies of a number of sites identified a former farm at Lephalale, Limpopo Province, as the most suitable location. A whole range of criteria was assessed, including the availability of primary resources, the ability to connect to the Eskom grid, environmental acceptability and cost of production. Lephalale benefits by being close to the existing Matimba power station, which already has access to the grid, and enjoys close proximity to a competitively priced primary source of coal. Having received the licence to build in 2006, construction activities commenced in May 2007. The first of the six units of the power plant is scheduled for commissioning during the first half of 2012 and the remaining five units will follow at six- to eight- month intervals. Once fully commissioned, the plant will contribute 4,764 megawatts to the grid and is expected to have an operational life span of at least 50 years. Construction of Eskom's second most advanced coal- fired power station is now under way at Delmas, Mpumalanga Province, and ground was broken on the project in 2007. Named Kusile, the plant has been sited close to the existing Hitachi Power Africa ( Pty) Ltd is a subsidiary of Hitachi Power Europe GmbH, which in turn is a subsidiary of Hitachi Ltd, Japan- one of the largest companies in the world. Hitachi Power Africa's products and services for the southern African market include: . Utility- steam generators for firing all fuels . Steam and gas turbines .

Engineering studies and design solutions for plant enhancement . Engineering, procurement and construction ( together with Hitachi Power Europe) Hitachi Power Africa is currently executing the local content for two power plant orders from the South African utility, Eskom. Projects comprise 6 x 800MW utility steam generators for each of the Medupi and Kusile Power Stations in Lephalale, Limpopo Province and Emalahleni, Mpumalanga Province respectively. The company is also facilitating the transfer of technology, skills and investment into South Africa. Hitachi Power Africa ( Pty) Ltd
