As far as SABS 1524, STS specifications and SABS IEC 1036 are concerned, most do not apply (OUT OF SCOPE).
Our system has the authority of the man in the blue overalls that goes around and reads the meters. Therefore, the authority of our system is the authority of the meter, it is directly proportional to how accurately we read the meter.

The last one, being CIM (Common Information Model), is not a standard that is widely supported. Where we integrate with equipment that is CIM compliant, we are also CIM compliant to the extent we need to be to read the equipment. Our main point of integration is equipment. We also have an integration point to the STS vending system, and to the Billing System (export monthly bills). The tariffs are completely configurable, so the compliance to NERSA is up to the client.
