For example using Groblersdal farming rates are presently R1.1345 KW/H; this means in 2017 it will be R2.0541 KW/H.
If Eskom then increases its rates at 20% per annum this figure will increase to R5.1113 KW/H by 2022  

•  Eskom is at least 15 years away from instituting inflation-cost tariff increases, as the power utility says it needs 16% increases for the next five years, followed by a similar period of 20% increases with a final five years of 9% increases.

•  Eskom chief financial officer Paul O’Flaherty said these increases were based on the assumption that Eskom generated 65% of the country’s electricity needs and independent power producers (IPPs), the remainder using mainly renewable energy sources.

•  In the interim, however, a framework for the introduction of a carbon tax was announced in the 2012 Budget Speech together with the proposal that a carbon tax be implemented in 2013/2014 at a rate of R120 per ton of carbon tax equivalent (CO2e) on direct emissions.

Impact Of Constant Price Rise

A carbon tax as being proposed by National Treasury will wreak havoc on the South Africa economy and will make it uncompetitive. Per the Budget documentation a rate of R120 per tonne of carbon dioxide (CO2) emissions is suggested as a carbon tax. A tax free threshold of at least 60% will apply. 

At the current rate Eskom will pay R11 billion per annum when the carbon tax is implemented, with escalations of 10% until 2020.

The above number does not take into account the implicit carbon tax already built into the electricity price for renewal energies and energy efficiency incentives administered by Eskom for which the country is already paying. Eskom in terms of its current pricing model will pass the additional tax onto consumers and thereby increase the price of electricity even further.




The impact on a constant price rise of 16% p.a. for 5 years then a 20 % p.a. for a period of 5 years and thereafter a 9% p.a. for 5 years - market related increases will be as follows:






What does the system consist of:
