Archive of Market Participant 5-Minute Forecast working group
The Market Participant 5-Minute forecast (MP5F) is a program undertaken by AEMO and ARENA, in conjunction with forecasting service providers and wind and solar projects, to demonstrate the potential benefits of wind and solar generator self-forecasting to market and power system operation. It is anticipated that the use of dispatch self-forecasts in preference to forecasts from AWEFS and ASEFS will deliver system wide benefits, by reducing generation forecast error and providing greater autonomy to intermittent generators.

Dispatch Self-Forecast Implementation Project
As part of the MP5F program, AEMO is implementing changes to its systems and procedures to allow market participants to optionally submit dispatch self-forecasts to AEMO via a web-based API, and for AEMO to use those forecasts in the dispatch process.
Market participants must register with AEMO to provide dispatch self-forecasts of the unconstrained intermittent generation from their semi-scheduled generating units for use in dispatch. See Participant Forecasting for more details.
The following table outlines the timeline for AEMO's API implementation and integration into Dispatch for this project, including indicative times for communication of design documentation and system implementations.
The MP5F Milestones document provides a detailed description of each milestone, including participant implications.

Semi-Scheduled Generation Self-Forecast - Assessment Procedure
In July 2018, AEMO invited feedback on the draft Semi-Scheduled Generation Dispatch Self-Forecast Assessment procedure.
In November 2018, AEMO considered feedback received and published a second draft of the procedure and associated draft determination.
In December 2018, AEMO considered feedback received and published the final procedure and associated final determination.
AEMO intends to follow this procedure in assessing the performance of Dispatch self-forecasts before allowing their use in 5-minute Dispatch.
AEMO intends to further engage with stakeholders during 2019 to review the effectiveness of the Self-Forecast Assessment Procedure (including metrics, benchmarks, thresholds and exclusions) after gaining sufficient experience with the use of self-forecasts in dispatch.
