Initial National Demand Out-Turn (INDO)

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

The 'D/L Embedded' page also allows for the download or more detailed demand information such as levels of emebddeded demand, embedded solar and embedded wind. This gives a better breakdown of demand figures.

The Latest page allows the user to view the latest initial demand outturn data.

The History page allows the user to view a history of initial demand outturn data.

The D/L page allows the user to download a file containing initial demand outturn data for a date range.

The D/L Embedded page allows the user to download a file containing initial demand outturn with embedded data such as wind forecasts and solar forecasts plus embedded demand for a date range.
