Innovative power solution for new port

Kohler-SDMO and its local partner, Select, recently won the tender, issued by the two shareholders of the new port of Doraleh in Dijbouti, for six 2 MVA generating sets. The generating sets are housed in CPU40 containers. They are coupled together in series and will supply power to the port and its cranes in the […]

What are microgrids?

Microgrids are stand-alone power generating, distribution, and storage systems which can be operated independently or connected to the primary utility grid. By locally optimising various generation sources, such as solar PV, gensets, the grid and energy storage, a microgrid can create a range of financial and environmental value streams for an organisation. This article describes […]

Eskom’s big blunder: How poor decisions and corruption caused load-shedding

South Africa is in the midst of an electricity crisis, which is curiously the result of plans by Eskom to prevent this exact scenario from happening. Energy analyst and EE Publishers MD Chris Yelland explained that Eskom was faced with two choices a few years ago: Spend money on maintenance of old power plants to […]

No more load-shedding?

According to the minister of public enterprises, Pravin Gordhan, Eskom has committed itself to keeping the lights on this winter by adding additional generating units to the grid and limiting the amount of generating capacity lost to unplanned outages. Speaking to a large media contingent at a hurriedly arranged media briefing at the Lethabo power […]

Nero fiddles, while the prospect of load shedding in South Africa continues

. Electricity customers and the public in South Africa experienced Stage 2 (2000 MW) manual rotating load shedding in late 2018 and Stage 4 (4000 MW) in February and March 2019. However, while Nero fiddles the prospect of further load shedding is set to continue in the months ahead. But there seems little sign that […]

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 […]

Cutting energy costs with microgrids

As South Africans suffer another round of power interruptions, imposed upon them by the national power utility which is unable to generate sufficient electricity to keep the lights on, advanced technology offers a realistic, affordable and environmentally-friendly solution. Six months ago, Energize visited Eaton’s factory in Wadeville, Germiston, to see a sophisticated microgrid which had […]
