A beginner’s guide to understanding STS

The power of STS is known worldwide throughout the energy industry and knowing exactly which route to take to benefit from this, can be daunting if you don’t know which steps to take, or even which questions to ask. Below are all the steps that will guide you through the entire process of having your product STS certified, or if you simply want to re-sell any STS certified products. 

*Please do take note that the STS Association does not provide guidance on the technical design of your STS compliant system, you will however receive guidance on the interpretation of any of the specifications, and any other STS related questions. 

For a detailed dive into everything STS, please go take a look at our training series presented by Franco Pucci. For now though, let’s begin by asking a question… 

  • Do you want to manufacture STS compliant products?

Meter
Vending
Security Module
Meter
For meter manufacturing

2.  What type of meter do you want to make? Gas? Electricity? Time? Currency? Water? – This depends on market requirements
3.  Purchase the IEC specs (IEC62055-41  /  -51) and download the relevant companion specifications that are required for your meter type (specification selector)
4.  Design your meter according to the required standards.
5.  Test the meter according to the STS certification documents
6.  Send meter samples for certification testing to an approved STS test house.
7.  Purchase a manufacturing security module in order to code your meters according to your customers requirements. 
9.  Manufacture & code the meters
Vending
For vending system manufacturing

2.  Is your vending system a token server? (web based) Or a point of sale?
3.  What type of vending system do you want to make? Gas? Electricity? Time? Currency? Water? – This depends on market requirements
4.  Purchase the IEC specs (IEC62055-41  /  -51) and download the relevant companion specifications that are required for your vending system type (specification selector)
5.  Design your vending system according to the required standards.
6.  Test the vending system according to the STS certification documents
7.  Setup a test date for certification testing with the test house
8.  Download the virtual security module in order to generate tokens during your test.
Security Module
For security module manufacturing

2.  Is your security module a manufacturing / vending / both? 
3.  Purchase the IEC specs (IEC62055-41  /  -51) and download the relevant companion specifications that are required for your security module type (specification selector)
4.  Design your security module according to the required standards.
5.  Certify your security module according to the requirements of STS600-10-1  This document specifies which international security standards you must meet.
6.  Test the security module according to the STS certification documents
7.  Setup a test date for certification testing with the test house
8.  When certification is complete register your SM firmware version with the KMC (see STS600-4-2)

  • Do you want to supply vending services to STS compliant products?

Are you designing your own system?
Are you using someone elses?

Are you using someone elses?

Are you using someone else’s vending product?


1)  Purchase a suitable vending system from an STS vending system supplier 

2)  Make sure it is an STS certified system by checking the compliance certificate of the product you buy on the website 

3)  Purchase a security module to perform all the STS token encryptions 

4)  Get a letter of permission from the SGC user that you will be vending to, and apply for this SGC to be loaded into your security module.

5)  Load the SGC into your security module using the keyload file supplied by the KMC
