The number of projects submitted to the South African National Energy Development Institute (SANEDI) committee responsible for evaluating projects submitted for the Section 12L tax allowance has increased... (more)
Solar stats to start the year
by Dr. Vince Micali, Stats4Buz
Dr. Vince Micali
 
I am afraid that this article, to kick start the year, needs to be on a more serious than humoristic note, and as a matter of fact, more pertinent to a fundamental subject which stands at the very heart of the publishers (and mine)... (more)
SONA debate loses energy
by Peter Marais, Frost and Sullivan
Peter Marais
 
President Jacob Zuma's recent State of the Nation Address (SoNA) gave little indication of how it plans to afford 9600 MW of new nuclear power capacity in the next decade. He hinted that nuclear would only be rolled... (more)

Small wind turbines for private power generation
by Mike Rycroft, features editor, EE Publishers

The development of utility scale wind turbines in the several megawatt maximum power range has been well documented and most are familiar with these products. The sub-megawatt range is however less well known but is a developing market... (more)
X-rays reveal details of plastic solar cell production
by Stefanie Reiffert, Technical University of Munich 

Plastic solar cells are light, easy to install, and readily produced using a printer. Nevertheless, the processes that take place on the molecular scale during the production of organic solar cells are not yet entirely clear. Researchers from the Technical... (more)
Solar storms: what is the risk to power transformers?
by Vladimir Gurevich, Israel Electric 
 

This article discusses the problem of the influence of geo-magnetically induced currents (GIC) during solar storms on power transformers. It is shown that there is no experimental data confirming the necessity to revise the traditional... (more)
Standards and the development of MV switchgear rated for arc flash protection
by Bryan Johnson, ABB

This article explains why IEC 62271-200 should be used by all users concerned with safety and security of supply, and addresses modern ultra-fast earth devices that help achieve the desired goals. Large utilities and industrial companies have been concerned... (more)

Calculations for overhead lines with varying weather and load data 
Information from Cigr�

There is a general need in the world for maximising the use of electrical infrastructures, forcing them to increase their maximum power capacity. At the same time, changes in the electrical systems and the need to integrate highly variable sources of... (more)
Smart substations: the cornerstone of a smart grid
by Yves Chollot, Renzo Coccioni and Laurent Guise, Schneider Electric

Utilities today face increasing pressure to improve the reliability and efficiency of the electric grid while simultaneously enhancing power quality. They must also support a higher ratio of distributed energy resources (DER), such as renewable energy sources... (more)
Latent ammonia storage: a revolution for renewable energy
by Johan Enslin, Heat Recovery Micro Systems

Ammonia is popular in power generation as an operating medium in organic rankine cycles (ORCs) for the recovery of heat at lower temperatures because of its higher vapour pressure, and therefore higher power density. Ammonia has also been used... (more)
Professionally planning South Africa's nuclear energy projects
by Dr. David Milne, David Milne and Associates

South Africa's ability to successfully manage its proposed nuclear energy projects should not be a problem as there exists within the country an adequate number of personnel with the necessary managerial experience and skills for the task... (more)
Proper maintenance preserves performance of gas turbines
Information from Sulzer

Gas turbines form a crucial part of many power generation facilities and provide an efficient and reliable power source that can be brought online as required. Maintaining that facility requires a well planned maintenance programme that will deliver... (more)
Traction motors in diesel locomotives
by Mike Rycroft, features editor, EE Publishers

Rail transport is coming back into favour for the transportation of goods over long distances. GE recently announced its intention to commence building of one of its diesel locomotives in South Africa. Alternators, electric motors and control systems are... (more)
