Eskom faces new power crisis
This shortfall is owing to Mpumalanga’s shrinking coal reserves, which need urgent supplementation with coal from the Waterberg area, which has 70bn tonnes of shallow coal reserves lying between Lephalale and the Botswana border.
Every year after 2018 the shortfall will assume greater proportions because of Mpumalanga’s shrinking reserves.
By 2040 only five of the 13 coal-fired power stations in Mpumalanga will still have coal.
Transport costs to Mpumalanga will be between R100 and R200/t, which means the coal will cost 50% to 100% more than the R209 that Eskom is currently paying for coal from those mines mostly close to the power stations. Electricity consumers will ultimately bear these costs.
Railway lines are now hurriedly being built to get the Waterberg coal in Mpumalanga, but the only long-term solution is to build more power stations at Medupi and Matimba in the Waterberg area, where half of the country’s remaining coal resources lie. Last month Eskom asked the 15 owners how much coal they can make available for the Mpumalanga power stations.
Exxaro, the only one of the 15 mineral-right owners producing coal, said it was prepared to provide 2m tonnes a year by 2014 and, by 2018, to increase this to 30m or even 40m tonnes, depending on Eskom’s specifications.
Transnet committed itself to improving the carrying capacity of the railway line to 23m tonnes/year by 2016 and eventually to push this up to 80m to accommodate, inter alia, for coal exports from Botswana.
Owners of the 70bn tonnes of coal in the Bushveld are however frustrated and disillusioned by the delay in providing a legal framework for erecting private, independent power stations while the country pays higher prices because of electricity shortages.
The electricity regulation bill and that on independent system operators, which will remove control of the country’s power grid from Eskom so that independent operators can also use it, has been dragging on for three years.
Construction of private coal-fired power stations cannot start before these matters are finalised. It has become increasingly obvious that independent power generators are the key to the country’s energy problems.
There is also enormous frustration in the mining industry because Eskom is buying electricity back from chrome smelters.
This winter this has brought half of the ferrochrome industry to a standstill and resulted in South Africa surrendering considerable market share to China.
“How can Eskom be proud of us getting through winter without power failures while effectively there has been commercialised load-shedding?” a player in the ferrochrome industry said to Sake24.

NEW DEVELOPMENTS FOR LEPHALALE
Mining group Exxaro is forming a separate company to develop a wide range of projects, including a R7,5bn concentrated solar power (CSP) plant near its Grootegeluk coalmine in Lephalale, Limpopo. The mine, which supplies Eskom’s neighbouring Matimba power station, is being expanded to supply coal to the utility’s new Medupi plant in the area.
Exxaro hopes to commission its 22 MW CSP plant in two phases of 110 MW each by 2014 or 2015, according to Ernst Venter, executive general manager for business growth.
If development of coalbed methane reserves proves viable, Exxaro could also use gas in the CSP plant as a feedstock at times when the sun is not shining. Coupled with storage, this would enable the plant to rival a coal-based power station’s ability to generate round-the-clock electricity.
Exxaro’s main aim is to sell electricity into the national grid, but power from its CSP plant could also be dispatched to its mining operations.
