No load-shedding this winter, says Eskom – but can we be sure?

The power utility’s interim group chief executive has assured the public that the organisation is committed to keeping the lights on this winter, despite low coal stockpiles at six of its power stations, by shifting plant performance and coal stock between power stations. At a media briefing at Eskom’s Megawatt Park complex, the power utility’s […]

Eskom to announce coal recovery plan to address imbalance in coal stock levels

The challenge of coal stock levels below the required target of 20 days at seven of Eskom’s power stations is not ideal, more especially as the power utility prepares for the traditionally higher electricity usage period in winter. The organisation has, however, put measures in place to address the current coal shortages. Eskom says it […]

Inside the “coal supply emergency” at Eskom…

Credible reports are being received of alarming coal supply problems at numerous Eskom coal-fired power stations in South Africa’s Mpumalanga province. The reports indicate that the situation has become so serious that Eskom’s primary energy division has recommended to the utility’s new generation head, Thava Govender, that a coal supply emergency be declared. This follows information […]

More nuclear power in China

The World Nuclear Association released a report on China’s electricity generating plans recently. The report – of which this is an extract – states that most of mainland China’s electricity is produced from fossil fuels, predominantly from coal – 73% in 2015. Two large hydro projects are recent additions: Three Gorges of 18,2 GWe and Yellow […]

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 […]
