The renewable energy, new coal and gas-to-power IPP programmes in SA – quo vadis?

South Africa’s energy sector is at the cross roads in an uncertain and incoherent policy environment caused by the self-induced chaos of the Zuma administration, with three ministers of energy in 2017 alone, and further political change likely after the ANC’s elective conference in mid-December 2017. According to Finance Minister Malusi Gigaba, failures of governance, […]

Battery pilot could power up 1600 jobs

A new research pilot plant for manufacturing materials used in batteries could ultimately lead to the creation of 1600 jobs.  Science and Technology Minister, Naledi Pandor, launched the Lithium Ion Battery (LIB) precursor pilot plant facility, established in partnership with the University of Limpopo, in Mbombela this week. The facility’s project manager, Danie Theron, said […]

Flexible, distributed, stored energy: the utility of the future

The Massachusetts Institute of Technology’s (MIT’s) Energy Initiative has undertaken the Utility of the Future study to serve as a guide for policy makers, regulators, utilities, existing and startup energy companies, and other power-sector stakeholders to better understand the factors which drive change in power systems worldwide. The report was supported by a consortium of 23 diverse […]

Eskom – a laggard in electricity utility transition

In South Africa, where electricity prices have quadrupled since 2007 and an expensive coal-fired power build-out threatens to drive prices even higher, renewables appear ever more appealing. Unfortunately, for the last two years Eskom has been stonewalling on this front, refusing to sign new renewable energy power purchase agreements, while claiming that renewable energy is […]

How nuclear can support green applications for a sustainable SA

We often hear about next generation nuclear power plants under development and construction worldwide. These nuclear power plants are designed from the ground up utilising different philosophies and more importantly, different objectives than conventional light water reactors widely in operation today. Fig. 1 illustrates how nuclear power plant designs have evolved since the late 1940s up […]

Power usage effectiveness in data centre management

Power usage effectiveness (PUE) is growing in popularity as an efficiency metric by the data centre market. While PUE is a tool to deploy an approach, or develop an implementation within a data centre, the measurement of PUE and its accuracy could have an increasingly negative impact. Where the energy manager of a data centre […]

Smart grids to reduce costs and improve service

In his opening address at the SAIEE’s Smart Grid Conference recently, the president of the South African Institute of Electrical Engineers (SAIEE), Jacob Machinjike, said that a smart grid infrastructure would provide unique opportunities for improved electricity services which would benefit people in Africa.   The conference, which was held at the Eskom Convention Centre […]
