The transition to a low carbon future must be rapid, and must be for everyone

In response to the interdict sought to stop yesterday’s signature of the Power Purchase Agreements (PPAs) for 27 renewable independent power producer procurement programme (REIPPPP) projects, the Life After Coal Campaign emphasises the urgent need for a rapid, but just transition from coal to a low carbon future. Workers in power stations and coal mines […]

Coal-mill optimisation in coal-fired power stations aids flexibility

Many of the existing pulverised coal-fired (PCF) power stations are operated at a fixed steady load (i.e. baseload operation). There is however a growing requirement for load following or flexible operation, which requires flexibility in most of the components of the power station. Flexibility and efficiency can be improved by close control of the coal […]

Eskom – a laggard in electricity utility transition

In South Africa, where electricity prices have quadrupled since 2007 and an expensive coal-fired power build-out threatens to drive prices even higher, renewables appear ever more appealing. Unfortunately, for the last two years Eskom has been stonewalling on this front, refusing to sign new renewable energy power purchase agreements, while claiming that renewable energy is […]

Tegeta clinched Eskom contract despite low quality coal

Eskom awarded an 11-year coal supply contract to former Gupta-owned mining firm Tegeta Exploration and Resources, despite it not meeting coal specification standards. In a written response to a parliamentary question posed by the DA’s Natasha Mazzone, Public Enterprises Minister Lynne Brown divulged a detailed list of Eskom’s current coal suppliers, the quantity of coal […]

A “just” transition to a lower-carbon economy

Despite knowing that both coal mines and coal-fires power stations have a finite life, it speaks to poor planning and the poor implementation of policy in South Africa that nothing has been done to address what comes after or to deal with the need to transition to a lower-carbon economy. Misinformation in statements published by […]

Coal ash conference: Production and utilisation with a multitude of opportunities

The end for “baseloadism” in SA, and the need for “flexible” power generation

  In the brave new world of power generation, the old paradigm and approach of dispatching baseload, mid-merit and peaking generation capacity, in that order to meet electricity demand, is being turned on its head. With the massive reduction in the price of renewable energy from wind and solar photo-voltaic (PV) plant over the last […]

How to transform the electricity system

  Speaking at an event hosted by the Centre for Environmental Rights (CER) recently, Markus Steigenberger, the deputy executive director of Agora Energiewende, said that the transformation of the German electricity system from a dependency of coal and nuclear to renewables has resulted in a significant reduction in harmful emissions and pollutants.     The […]

Rise in global gas demand predicted

  The International Energy Agency (IEA) predicts that the global natural gas market will undergo a major transformation driven by new supplies coming from the United States to meet growing demand in developing economies. The evolution of the role of natural gas in the global energy mix has far-reaching consequences on energy trade, air quality and […]
