Using public data supplied by NERSA I put the spreadsheet through the AI mill for a summary of the tariffs – ONLY for Domestic Credit (Conventional) meters on the highest scale.
From that we developed:
- A table comparing the domestic electricity prices for all the major metropolitan municipalities in South Africa
- A summary of the 10 highest domestic tariffs per unit
- A summary of the 10 lowest domestic tariffs per unit
Frankly – this exercise highlighted one worrying concern: The number and style of the thousands of tariffs offered do not make for confidence in the pricing of electricity. The many different tariffs present an opportunity for wholescale corruption and fraud. I wonder if any of the municipalities have strong audit mechanisms in place to ensure that, for example, a Credit meter does not have an incorrect classification applied to it as an ATTP meter or a commercial meter being classified as a domestic? And, are these audits applied on a regular (more than annual) basis?
The Danger of ‘Cherry-picking’:
One of the first lessons we learn in stats is that they are not to be trusted – you can find a statistic to support your position (especially if you are a politician). This then is the reason why we as a country need to move to a more definitive and standardised way of classifying the price for electricity per unit.
For example – Cape Town will be very aggrieved to find themselves being fingered as the highest price provider in the country and will be quick to get hold of me to challenge my numbers by citing some other tariff that is lower than others in the country.
But, what we are all missing is that we cannot really compare numbers individually – even when I have chosen to highlight the highest charge per charge for the domestic post paid consumers as the IBT levels are NOT aligned. So, beware of making quick assumptions about which municipality is the cheapest or most expensive overall.
Well, you could then apply the “Where there is smoke there is fire principle” to the numbers below to get a sense of costs.

Straton Prepaid Reveals:
For those of us needing to recover electricity consumption by tenants in a multi unit office or home the route to go is via private prepaid electricity and/or water meters.
These meters are subject to the same testing and measurement procedures by South Africa authorities as municipal meters.
Straton Prepaid sells prepaid electricity and water meters online via their shop at Stratlec.co.za – along with a host of Shelly Products, Shelly Accessories and other hard to find electrical goods.
Advantages:
The sequence of events up to installation here normally operate far faster than your local municipality.
You get to deal with Call Centres and Technical personnel that are very motivated to assist, solve problems and queries.
No monthly reading of conventional meters and invoicing tenants with accompanying difficulties to collect.
A Payment processor that monitors your tariff and automatically adjusts when necessary.
Often cheaper to buy and install than a conventional municipal meter.
Still within the NERSA ‘regime’ – that states that landlords may NOT make money from the resale of electricity but MAY recover admin fees which include payment processing fees, bank fees and a portion of admin fees. Often there will be three sets of bank fees – Client to EasyPay, EasyPay to Payment Processor, Payment Processor to Landlord.
Disadvantages:
The electricity cost per unit to the tenant is higher (up to 12% more including VAT) as a result of the admin and bank fees.
Some Payment Processors may lock landlords into them exclusively by asking for very high fees to issue a Key Change Token. This Key Change Token allows landlords to migrate to a different payment processor. At present there are 633 different Payment Processors listed on the EasyPay Site so choose carefully which one you want to go with.
Ask about how much the payment processing fees are – most Payment Processors will include the admin fees in the per unit price paid by your tenants but, make sure of this beforehand.
Ask about how much your Payment Processor will charge for a Key Change Token and get it in writing. Often this fee will be dependant upon how long your account has been in effect.
If the wheels fall off for your Payment Processor then, at best case, you will lose a month’s collections – remember these Payment Processors collect the tenant payments on your behalf and then pay you once every month. You, in turn, then settle the municipal bill.
Who Should You Trust?
Of course I am going to say, in public, that Straton Prepaid and their Payment Processor – PMD are the right people to deal with.
Why?
Straton Prepaid (part of Straton Electrical) have been in business since 1966 – in the days when a man’s word was his bond. Straton Prepaid handles the Eastern Cape with installations of prepaid meters whilst PMD does the Payment Processing for tens of thousands of meters countrywide with offices in George, Cape Town and Johannesburg.
We have had prepaid meters of our own with PMD for more than 10 years and can attest that PMD have never missed or been late with a payment cycle – like clockwork the money lands in our account on or before the 7th of each month along with a statement detailing purchase, sales and cost.
Straton Prepaid service many different clients – from small flatlets to large three phase commercial to large international communications clients with specific tailored needs that PMD are flexible enough to accommodate within the constraints of their system.
