Margin

This group of pages contains information on margin. This currently only includes the MELNGC, Indicated Margin, data.

The MELNGC pages show indicated margin data. The Indicated Margin forecast for each Settlement Period is the difference between the sum of the MELs submitted for that period, and the National Demand Forecast made by the System Operator. The greater the value, the higher the margin between available generation capacity and forecast demand - that is to say, the more spare capacity there is forecast to be in the system.
