IRP INPUT PARAMETERS

24 input parameters have been identified as critical to the modelling process for the IRP. Each of these Parameters has an associated Fact Sheet, which describes to the stakeholder the nature, impact, value, ranges of values and other pertinent information on the parameter and its importance to the final IRP. From the first stage of consultation the following values for these parameters have been set. These values will then be used in the modelling process.
