On 23 August 2011, EE Publishers hosted an open panel discussion and debate in Midrand, entitled “Renewable Energy in South Africa – going backwards or forwards?” At the debate, key players in the renewable energy (RE) sector of South Africa covered the background on where the country finds itself now, as well as the road ahead in the implementation of the ambitious renewable energy targets detailed in the national integrated resource plan for electricity, IRP 2010 – 2030. This will involve the installation of some 9200 MW of wind generation capacity, 8400 MW of solar photo-voltaic (PV) capacity, and 1200 MW of concentrating solar plant (CSP) capacity by 2030… (more)

At long last, the cabinet has approved and published the national Integrated Resource Plan for Electricity, IRP 2010. Now this just has to be passed by parliament and published in the Government Gazette. Let’s hope there will not be further delays, and that a measure of certainty will prevail so that the electricity sector can get down to work. But what is IRP 2010? Why is it important? And what exactly does it say?… (more)

It is well known that the price of electricity in South Africa has been too low for years. The generation capacity crisis in 2008 prompted a review of Eskom’s build programme and associated funding plan. The original expectation was that there would be a short-duration adjustment to bring prices to the correct level, and thereafter electricity prices increases would follow inflation. But the adjustment did not develop in line with expectations, and price increases much higher than inflation are expected for many years to come… (more)

Eskom, the South African electricity utility, is facing a diverse range of social and economic challenges. This is hampering business progress and infrastructure growth, which are elements key to the long term sustainability of the utility. The key to having a sustainable business is the alignment of processes and technologies to meet the demands of present and future network uncertainties. Success will depend largely on the optimal use of assets and strategic investments… (more)

It has been clear from events towards the end of 2007 and into 2008 that there is an inadequate supply-demand balance in South Africa. The global economic downturn during the second half of 2008 gave some temporary respite to the electricity system, but demand has already picked up to the 2008 levels and is growing, while we are not adding significant new generation plant to the system until Medupi’s first unit is planned to come on line in 2012… (more)

An electrical engineer was asked why he was leaving for London to take up a managerial position in an electrical supply company. His answer was that he desired a professional working environment so that he could grow, be a better engineer and have a sense of fulfilment. These desires probably hold true for most of us. The question then is: how do we create and sustain a professional working environment that inspires staff and produces the desired results?… (more)

An authorised person closed an 11 kV oil circuit breaker (OCB) on to a fault at a main substation. The OCB exploded and the force of the blast blew off the substation doors, seriously damaging the building. The authorised person broke his right arm when the door behind which he was standing was blown open. The fire that followed destroyed all the equipment within the substation. This paper looks at the incident, the cause and the actions to be taken to prevent a recurrence of a similar incident… (more)
