Air quality rules may force Eskom to close power stations

Proposed new air quality rules will force Eskom to comply with pollution standards or shut down its polluting power stations. Most of Eskom’s ageing coal power stations cause severe air pollution, which contribute to the deaths and ill-health of thousands of South Africans every year. Despite this, Eskom has thus far been let off the […]

An assessment of new coal plants in South Africa’s electricity future

.  An important new research report by Gregory Ireland and Jesse Burton, of the Energy Research Centre (ERC), University of Cape Town, was published on 30 May 2018. The report assesses the cost, emissions and supply security implications of South Africa’s coal baseload independent power producer (IPP) procurement programme which was launched in 2014 in line with […]

The new IRP for electricity, and the future of coal in the electricity generation mix of SA

A keynote presentation by Chris Yelland, managing director and investigative editor at EE Publishers, at the workshop on Air Quality, Emissions and the Low Carbon Economy hosted by the Fossil Fuel Foundation (FFF) in Johannesburg on 30 May 2018. On 16 May 2018, I made a keynote presentation at the annual conference of the National […]

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 […]
