How much is Eskom grid electricity going to cost you if you do nothing about it?

Over the period 2007 to 2017, Electricity prices increased on average by over 375% compounded, compared to a compounded inflation rate of 45%. In other words, an electricity bill of R700 per month back in 2007 has increased to more than R2800 per month today.

Do you know how much you are really going to spend on electricity over the next 10 years if you dont convert to solar?

Given the poor state of the Eskom fleet and collapsing municipal infrastructure, the high cost of the new power stations which are slowly coming on stream and the very real likelihood of a coal cliff when SA runs out of coal, Eskom price increases will continue to be radically higher than inflation levels.

So how much can you expect to spend?

Taking a conservative viewpoint that Eskom will increase prices by 11% and that municipalities will add a further 3% – 4% so 15% increase per annum, the bad news is summarised below:

  • Without any solar intervention
Current electricity spend per month Monthly spend per month in 5 years Cumulative spend in 5 years Monthly spend in 10 years
R1 500 R3732 R139 572 R9 287
R2 500 R5 474 R232 608 R13 621
R3 500 R8 958 R325 656 R22 290


Even worse if these numbers turn out to be too conservative – with Eskom’s almost R500billion debt burden you can be sure you will be carrying the can for exponential electricity price increases.

It’s more mind-blowing when you consider that if you have a current electricity bill of R2500 or more, and you invest in a SMILE5 with 10kWh of battery back-up, your PV system would pay for itself in just over 4 years and thereafter, you would have another 20 years of zero to minimal electricity bill from council every month – let that sink in.  Still think it’s not worth your while to redirect the money you would be spending on grid electricity to your own residential PV system?

Procrastination is the thief of time…and your money! 

The good news is that you can do something about it.  By going solar and starting your journey to getting off the grid, step by step, with One Energy.
