The Short-Term Energy Market (STEM) provides Market Participants with an ability to buy and sell electricity in a day ahead forward market to manage their contracted position. The STEM processes include provision of contractual position, bids and offers for the day ahead market, and calculation of a Net Contract Position for settlement. 

The STEM remains structurally similar to the current design through Reform. However minor system changes will be required to accommodate changes to the STEM Submission timetable and STEM submission data requirements introduced through the new WEM Rule.
