Initial Transmission System Demand Outturn (ITSDO)
This group of pages contains functions to view initial transmission system demand outturn values. The Initial Transmission System Demand Out-Turn is the average megawatt
value of demand for a Settlement Period INCLUDING transmission losses, station transformer load, pumped storage demand and interconnector demand.
The ITSDO is made available by the System Operator within 15 minutes after a Settlement Period, based on their operational metering.
The composition of the Initial Transmission System Demand Out-Turn matches that of the Transmission System Demand Forecast and so ITSDO and TSDF are comparable.
