Integrating renewable energy sources into smart grids – Part one

There is global momentum to diversify electricity generation sources for economic, environmental and security reasons. Distributed generation (DG) enables more companies to enter the electricity market stimulating competition, encourages the development of renewable energy (RE) and limits the impact of events such as cyber attacks. However, conventional electricity distribution networks are poorly matched to the […]

Onsite power for remote mining locations

The need for a secure, efficient power supply is as important to mining operations as the equipment used by the mine to keep production up and running, sometimes on a continuous basis. Many remote mine sites are located at a great distance from the nearest power grid, resulting in the need to establish reliable off-the-grid […]

Solar power overnight

Vast Solar has built a modular, grid-connected 6 MWth CSP plant with thermal energy storage, at Jemalong, New South Wales, Australia. The plant is designed to achieve high efficiency at low cost. Each of its five, small array-modules concentrate solar radiation on a dedicated thermal receiver tower 27 m in height. The five modules connect […]

Powering the steel industry

Both metallurgical and other industrial plant processes, as well as large drive procedures depend on reliable, highly specialised transformers. In steel plants, for example, it is crucial to supply high currents for AC and DC electric as well as ladle furnaces. Electrolysis processes operate with heavy-duty rectifiers which are fed by rectifier transformers. Large drive […]
