Inus Dreckmeyr’s Netshield SA uses a basic formula when advising customers on the costs of producing 95% of a household or business’ energy needs. He describes it as a useful tool to see how much your household
has to pay to rid itself of Eskom. The first step is to look at your monthly
energy bill. Then multiply the monthly amount by 12 and then seven years, adding
15% interest on to every year.
For a R400 monthly bill, it will cost you R53 000 to make your house self-sufficient. For an R800 bill, you will need R106 000. A R1 000 bill will cost you R132 000 and a
R2 000 bill will cost R266 000
