Near Realtime Operating Data
The IMO must make the following values available from the Market Web-Site for each Trading Interval in the previous 12 calendar months as soon as possible after a Trading Interval:
- the total generation in that Trading Interval;
- the total spinning reserve in that Trading Interval. Spinning Reserve is a supply capacity held in reserve from synchronised Scheduled Generators, Dispatchable Loads or Interruptible Loads, so as to be available to support the system frequency in the event of an outage of a generating works or transmission equipment or to be dispatched to provide energy as allowed under these Market Rules. This service holds capacity in reserve to respond rapidly should another unit experience a forced outage. The capacity would include on-line generation capacity, dispatchable loads and interruptible loads (i.e. loads that respond automatically to frequency drops).
- an initial value of the Operational System Load Estimate, taken directly from System Management's EMS/SCADA system. Market Rule 6.14.4(a) indicates that the "Operational System Load Estimate" for a Trading Interval is the estimate that the IMO receives from System Management of the total Loss Factor adjusted MWh consumption supplied via the SWIS during that Trading Interval. This estimate equals the total loss adjusted generator sent out energy as estimated from generator operational meter data and the use of state estimator systems.
information can be found in the Market Rules and the Market Summary Document.
