Electricity
Power and automation technology group ABB has won an order from state-owned power utility Eskom to provide electrical and automation solutions for three of its largest plants. The order is worth $54-million and ABB has been tasked to improve the reliability and energy efficiency with their solutions.
Omphi Aphane, the Chief Director for Electricity at the Department of Energy (DME), recently spoke to 25º in Africa about the National Integrated Resource Plan (NIRP) which was announced early in December 2009. This plan, which opens the doors for independent power producers (IPPs), is set to be up and running by March 2010.

SA opens door for IPPs

On the 3rd of December 2009, the government opened the door for independent power producers (IPPs) by announcing the National Integrated Resource Plan. In addition to this plan, Energy Minister Dipuo Peters said that the department is also creating a new entity, the Independent System Operator (ISO), which will not reside within Eskom.
“We must not be too quick to rely on standard engineering principles,” comments Arup Mechanical Engineer Graham Peters, and adds: “We need to continually investigate alternative methods. In today's climate, it's
inexcusable not to think outside the box”. Peters favours a forward thinking approach which entails designing the most highly efficient engineering solution which involves looking at passive or low-energy systems first – and then employing systems of a traditional nature if this is absolutely unavoidable.

Design of wind farms and their integration

In the future, wind farms are going to become a more important part in the generation of electricity on account of the worldwide need to reduce carbon emissions and contain climate change. Over the past decade, the technology has matured and wind farms are now a common sight in Europe, the USA and China. In certain instances, they can also provide the generation of electricity to customers, thereby reducing the load on the local grid, freeing up capacity on the transmission and distribution electricity
networks and reducing transmission losses.

Results of the Greenhouse

Strategies Conference
As global warming and climate change take centre stage in international discussions for the industrialised and developing countries, South African companies are being forced to prepare themselves for compulsory carbon emission reduction requirements.

Public power: 2010 and beyond

Whether your business is in the private or public sector, the growing need for ‘power security’ places an increasing emphasis on standby solutions. Rod Warnes, Senior Manager of Barloworld Power’s Turnkey Power division explains that this emphasis has rippled across all industries who need to achieve uninterrupted operation, come rain or shine.

Laser-beaming electric power from space

Beaming electric power from space as a viable solar energy option may not be as far-fetched as it sounds! The practical application of this concept could be markedly accelerated by experiments ? some employing the International Space Station and including orbital mirrors and microwave and laser-beaming in space, says engineer and researcher Martin Hoffert.

SA's electricity consumption down by 2,1%

South Africans used 2,1% less electricity in July this year in comparison with the same month in 2008, revealed Statistics South Africa (Stats SA) recently. The estimated seasonally adjusted electricity consumption was 5,3% lower in the first seven months of 2009, when compared with the first seven months of 2008.
