Extending standby generator lifetime through maintenance

  Standby and portable generator maintenance has become almost synonymous with achieving reliability, with the role of the maintenance professional being to maintain generation equipment at its peak operating reliability in the most cost effective manner possible. This paradigm shift has come about over the last ten years as dependence on standby generation has increased. […]

The economics of fracking: Resources, reserves, and recovery efficiency – Part three

  Part three of this article deals with the use of fracking resources in transport and other applications by countries which are already active in this field. Parts 1 and 2 may be found here: www.ee.co.za/article/economics-fracking-resources-reserves-recovery-efficiency.html, www.ee.co.za/article/economics-fracking-resources-reserves-recovery-efficiency-part-two.html One lesser known use for natural gas – including liquefied natural gas (LNG) – is for transport. While not ideal […]

Gas to electric power generation potential

  Gas power generation (GPG) has increased significantly in the past few years , with gas overtaking coal in some countries. GPG offers greater efficiency and lower CO2 emissions than coal, as well as other operational advantages. The shale gas potential in South Africa as well as natural gas discoveries in southern Africa have increased […]

The economics of fracking: Resources, reserves, and recovery efficiency – Part two

  This is part two of an article which discusses the implications for the United States and Europe of importing shale gas from cheaper sources; the possible re-emergence of the use of coal in these regions, and questions around the validity of the figures being projected. “The USA will be the world’s largest producer of […]

Technologies for clean coal-power generation

  Coal is going to be an important component of power generation for many years to come. Increasing environmental requirements state that pollution associated with the burning of coal for power generation must be reduced if not eliminated altogether. Technologies for the removal of the harmful by-products associated with the burning of coal have been […]

Flexible gas engine concepts support renewable energy in power systems

  As the amount of variable renewable generation increases, in order for production to meet demand, sufficient balancing capability is needed. This requires greater flexibility in the power system, and generation technology based on internal combustion gas engines is one of the evident alternatives. Modern gas engine power plants with multi-engine concepts have numerous combinations […]

Pumped storage scheme’s HV yard successfully energised

  Eskom successfully energised the high voltage (HV) yard and three power lines at the Ingula pumped storage scheme in June 2014. The project is currently under construction near Ladysmith on the border of KwaZulu-Natal and the Free State. The Ingula pumped-storage scheme, located within the Little Drakensberg mountain range, 23 km north-east of Van Reenen’s, […]

Standby or auxiliary power generation set sizing

  With the decreasing reliability of the grid power, standby generators have become a common feature in consumer networks.  In some cases of high reliability requirements, fixed on-site generators are used as the primary power source. In other cases, where power outage during a performance or event is unacceptable, the standby plant is used as […]
