Note:
The National Electricity Market registration classifications of Anglesea Power Station Unit 1 (dispatchable unit ID: APS) and Yarwun Power Station Unit1 (dispatchable unit ID: YARWUN_1) are market non-scheduled generating units. However, it is a condition of the registration of these units that the Registered Participants comply with some of the obligations of a Scheduled Generator. Both units are dispatched as scheduled generating units with respect to their dispatch offers, targets and generation outputs. Accordingly, information about APS and YARWUN_1 is reported as scheduled generating units information.
The Tumut 3 Pumps (dispatchable unit ID: SNOWYP) are not classified as scheduled load in the National Electricity Market. However, they are required to comply with some of the obligations of a Market Customer in respect of a scheduled load. The Tumut 3 Pumps are dispatched as if they were scheduled loads with respect to their dispatch bids, targets and consumption. Accordingly, information about SNOWYP is reported as market scheduled load information.
