DRAFT PARAMETERS FOR CONSULTATION

29 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. The first stage of consultation (post registration) will be to comment on the values of these parameters. Once agreement has been reached on the values, these values will then be used in the modelling process.
