The South African Wholesale Market Code

What is

Market code

The development of the Market Code is an integral part of the new electricity supply industry. These rules will inevitably shape South Africa’s future. Therefore, be a part of this development and shape your future.

  • The Market Code provides the guidelines for buying and selling electricity between generators, retailers, and traders. It supports the short-term delivery and use of electricity, while ensuring medium- and long-term security of supply.

  • It also sets out the trading and settlement rules and procedures for participation in the competitive electricity market of South Africa including the required supporting functions and regulations.
  • It is a condition of the expected Market Operator Licence (once the ERA amendment bill is passed) that the Market Operator shall enter into and at all times administer and maintain a Market Code and rules which: 
    1. sets out the terms of the trading and settlement arrangements for the sale and purchase of wholesale electricity in the South African Wholesale Electricity Market (SAWEM);
    2. includes procedures for making changes to the Market Code, ensuring that any major modifications follow a transparent governance process. This allows participants and stakeholders to propose and comment on changes.
