A different type of grid is needed to solve SA’s energy challenge

  South Africa would get a much better return on its energy investments if it planned a smarter and more flexible electricity grid. A better grid would also boost the contribution of wind and solar energy. Government’s response to power shortages and load-shedding has been a thrust towards more power generation from coal-fired power plants, […]

Making the most of solar thermal energy

  Concentrated solar power (CSP) generation uses solar radiation to generate electricity from solar thermal energy. This power generation is employed in regions of high solar insolation, especially in the Middle East and North Africa (MENA) region, the United States, western India, South Africa, and Australia. While many commercial CSP plants are operating at present […]

First half of 2015 sees huge cost savings from renewable energy

  A second independent study by the Council for Scientific and Industrial Research (CSIR) found that renewable energy from South Africa’s first wind and solar (photovoltaic) projects created R4-billion more financial benefits to the country than they cost during the first six months of 2015. The full presentation may be downloaded here The study is […]

Gas-insulated transmission lines: the next generation of power transmission?

High voltage underground cables for power transmission have been in use for many years and number of different technologies have developed over the years. Solid insulation cables have limits when it comes to the voltage that can be carried safely, and oil impregnated paper cable are also limited in the capacity. Gas insulated transmission lines […]

How will SA’s new nuclear power stations be paid for?

  The South African government has committed itself, by means of its Nuclear Energy Policy and Integrated Resource Plan, to an energy mix consisting of coal, gas, hydro, nuclear, solar and wind. Yet, if the government is so determined to pursue nuclear power stations, why was no mention of the financing for this included in […]

NERSA’s regulations regarding small scale renewable energy embedded generation

  NERSA has issued a discussion document on small scale renewable embedded generation (SSREG) [1] for discussion on a possible regulatory framework for this sector of the market. This article summarises the main features of the document. The discussion document (DD) is primarily targeted at rooftop solar, a growing sector of the market, ranging from […]
