Majuba doubles its output after disaster

  Eskom reports that it has increased the power output from Majuba power station from 600 to 1200 MW.  The additional power has assisted with the management of water levels at its Drakensberg and Palmiet pumped water schemes which are used as peak demand stations, and has saved the country from load shedding. The utility […]

Joburg’s power woes worsen

  Large parts of Johannesburg are without power as a result of a technical problem, not at Eskom’s power stations, but at City Power’s infrastructure. City Power and Eskom technicians are on site working to restore power to the Prospect substation which feeds several smaller substations, which in turn supply power to many parts of […]

Economist to speak at the 9th SA energy efficiency conference

  Rob Jeffrey, the managing director and senior economist, at Econometrix will be addressing delegates at the 2014 Southern African Energy Efficiency Convention (SAEEC) on Wednesday 12 November 2014 on the keys to South Africa’s economic, social and political prosperity.

Windaba 2014: full range of RE technologies to tackle energy crisis

  As Eskom continues to declare regular “emergencies” and black outs persist, renewable energy including wind, has the potential to rescue the situation over the next five years – we just need to mix small and large scale technologies, says the South African Wind Energy Association (SAWEA). Windaba (Cape Town international conference centre, 3 to […]

Managing Southern Africa’s electricity networks

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 […]
