The portal will accept submission of availability for future 30-minute intervals, covering PD and STPASA time frames. The availability entries for each interval are carried forwards to the respective interval of future trading days, until a future trading day where an availability entry exists or is entered. Therefore, it is expected submissions are made only to indicate changes to availability, not to exhaustively specify availability in each interval of each trading day. The interval datetimes in a single day do not have to be consecutive. Availability information can be submitted for any interval in the future, even if beyond the PD/STPASA forecast horizon.
AEMO Australian Energy Market Operator implements a default intermittent generation availability entry as part of the registration process. The default availability is a 0 megawatts (MW Megawatt) generation capacity and the elements (turbines/inverters) in each cluster are unavailable. Participants are expected to submit the PD/STPASA availability entry to ensure their availability matches their requirements.
