Managing Southern Africa’s electricity networks

  The City of Johannesburg in conjunction with City Power hosted the 64th Association of Municipal Electricity Utilities (AMEU) Convention at Gallagher Estate in Midrand from 5 to 8 October 2014. The theme for this year’s convention was “Moving towards Southern Africa’s electricity networks of the future”. The keynote address was delivered by Dr. Wolsey […]

Municipalities instructed to improve service delivery

  The Department of Energy’s Dr. Wolsey Barnard, says South African municipalities need to improve electricity service delivery  and clear backlogs so that more residents can have access to electricity. Speaking at the opening of the 64th annual AMEU convention held at Gallagher Estate, in Midrand on 5 to 8 October 2014, Dr. Barnard, the […]

South Africa: Electricity pricing paralysing the poor

  The electricity sector in South Africa has been in a state of disruption over the last few years. The country’s power utility company, Eskom, has been under scrutiny for several reasons. Most of these reasons relate to the rolling blackouts, load-shedding episodes of 2007/8 and high levels of inefficiency. Constant tariff increases under the […]

Promoting energy access: Meeting the challenge with cogeneration

  The International Energy Agency reports that nearly 1,3-billion people still lack access to electricity, and two-thirds of those people live in ten countries – four in developing Asia and six in sub-Saharan Africa. The agency estimates that nearly $1-trillion in cumulative investment is needed to achieve universal energy access by 2030 [1]. In its […]

Losses and costs associated with HVDC and UHVDC transmission lines

  Reduction in electrical energy consumption requires power utilities to employ most efficient ways of electrical energy delivery from generation to distribution infrastructures. For bulk power transfer over long distances improved transmission efficiency is a primary target to ensure less electrical energy losses and costs. The application of conventional HVDC schemes at 500 kV DC […]

Call for papers for Cigré’s 2015 international symposium

  The Cigré International Symposium will be held at the Lord Charles Hotel, Somerset West, Cape Town, from 26 – 30 October 2015. The theme of the symposium is “Development of electricity structures in sub-Saharan Africa”. The symposium is aimed at transmission, distribution and generation owners, system operators, suppliers, designers, traders, regulators, research laboratories and […]

Transmission and distribution network grows

  Frost and Sullivan reports that Kenya, Tanzania and Uganda, members of the East African Power Pool (EAPP), have embarked on regional interconnection projects in order to enhance the region’s transmission and distribution network. This is expected to foster cooperation between the countries and develop economic growth. Several major projects are underway including the US$1,26-billion, […]

Procurement models applied to IPP programmes in South Africa

  The Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) is largely viewed as a positive and innovative programme. We need a base-load procurement model that builds on the successes of the REIPPPP and extends these to base-load IPPs. Eskom’s future financial health presents a significant risk to procurement of renewables, thermal base-load and nuclear […]

Industrial power and energy savings initiatives in South Africa

  The electricity crisis of 2008 sparked an unprecedented interest in electrical energy efficiency. In the previous era of the cheapest electricity in the world and an abundant supply, little attention was paid to efficiency of electricity usage. The crisis resulted in numerous initiatives by government, the utility, industry associations and consumers, all aimed at […]

Falling electricity demand makes solar uptake more noticeable

  The long-held belief that electricity consumption would continue to grow is being challenged in a number of mature economies in the past few years. Since WWII, electricity demand growth has persistently fallen relative to growth rate of GDP in nearly all mature economies. Fig. 1 illustrates the negative growth in electricity use in the […]
