Why is the prepaid electricity rate per kWh more expensive than post billed electricity?

The kWh rate is determined by the Trustees.
The rate calculated must be sufficient to cover both the summer and winter electricity tariffs as well as the higher rate during peak times billed by Eskom/the Local Municipality.

The Trustees review the total bill for the year for the electricity consumption by the residents and work out an average rate per kWh to ensure that the total electricity bill is paid from the funds received from the prepaid provider.

If you would like to query the rate, please send an email addressed to your complex's Trustees to Support@stss.co.za and the STss Team will escalate your query to the Trustees of your complex.
