Forecasts of intermittent generation are critical to maintaining both power system security and an efficient market.

AEMO operates systems to forecast both solar and wind power:

• Australian Solar Energy Forecasting System (ASEFS)
• Australian Wind Energy Forecasting System (AWEFS)

Information for participants operating semi-scheduled generators is available in the Guide to Intermittent Generation.

In early 2018, AEMO and ARENA began undertaking a Participant Forecasting program to demonstrate the potential benefits of wind and solar generator self-forecasting to operation of the power system. It is anticipated that the use of self-forecasting will deliver system wide benefits by reducing generation forecast error and providing greater autonomy to existing intermittent generators.
