Web Services

The Wholesale Electricity Market System (WEMS) was designed with 3 methods of communication:

  1. the Market Participant Interface - a browser-based interface;
  2. transfer of information via XML files; and
  3. web-services.

The first two methods are maintained by the IMO to ensure consistent levels of reliability and up-time. They ensure that Participants can access the Market Systems.

The WEMS also has the ability to interact with Participants via web-services. The below documentation file is provided to allow Participants to develop their own systems, should they wish.
