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 needs […]
Electrical power applications are changing rapidly. LED lighting is replacing incandescent lamps, variable speed motor drives replace directly coupled electric motors, and photovoltaic (PV) installations and wind turbines generate additional electrical power. This means the load on the electric network is changing. More harmonics and more risk of unbalance. This so called “bad” power costs […]

Industrial power quality (PQ) solutions generally consist of discrete devices to deal with individual problems, and if more than one problem needs to be dealt with, more than one device is required. Developments underway incorporate electronic circuitry in the secondary circuit of an industrial distribution transformer that can handle all of the PQ problems in […]
DuPont Photovoltaic and Advanced Materials’ (DuPont’s) 2019 Global Field Reliability Study shows that the choice of backsheet material used on PV modules can result in significant degradation and negatively impact solar module performance. The report lays out failures with PET, polyamide and PVDF backsheets and issues with glass-on-glass modules. The report also highlights trends in […]

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 […]
The opening of the Kathu concentrating solar power (CSP) plant on 4 April adds a further 100 MW to the operating CSP capacity in South Africa. Part of Window 3 of the renewable energy independent power producers procurement programme, Kathu Solar Park (KSP) was synchronised to the grid in November 2018 and started delivering power […]
. Further to information received from reliable sources last year, and published by EE Publishers in an article in September 2018, Standard Bank has now explicitly confirmed to EE Publishers in writing that “as things stand presently, Standard Bank is not involved in the financing of either the Thabametsi or Khanyisa [new coal IPP] projects”. […]
Electrical power generation and distribution have become emotive topics in South Africa due to periodic disruptions to supply over the last decade. Public opinions are often shaped by news coverage [1] and in particular quality newspapers [2]. The Mail and Guardian newspaper was studied to determine how issues surrounding power generation have been covered. This […]
