The Jacob Marley column: Hickory, dickory, dock

  Sir Clocks have always played an important role in power systems. From the earliest days when George  Westinghouse’s alternating current won the commercial battle against Thomas Alva Edison’s direct current, and in spite of the comeback that DC rightly made in later years, every generator (or inverter) in the system must run at synchronous […]

Integrating a wind farm into a transmission or distribution system

  South Africa’s Renewable Energy Independent Power Producer programme (REIPPP) has produced keen interest by Independent Power Producers in wind energy facilities (WEFs) [1]. Integrating a WEF into a transmission or distribution network not only requires good engineering practices but also conformance to the NERSA grid connection code. This paper considers some of the requirements […]

Power to grow sub-Saharan Africa’s economy

  While achieving a buoyant economic climate is a feat in itself, the real challenge lies in staying afloat. To sustain the economic optimism that Africa is now enjoying, it is imperative that governments, particularly in sub-Saharan Africa, address the critical issue of chronic power shortage, which hampers the development of various industries in the […]
