This value represents the annual planning reserve margin target for the zone, where
Planning Reserve Margin = ( ( Existing Capacity + Future Capacity + Firm Imports – Firm Exports ) / (Peak Demand) – 1 ) * 100.
This value should be entered in percent, and can be specified as a time series. If the field is NULL (or this column is not present) in a long-term run which uses the Use reserve margin capacity targets option (located in the Long Term folder of Simulation Options), the value will default to 15%. If the zone says the minimum is 13.3, and the pool says the minimum is 15, then the minimum is 15 (i.e., both are honored). Aurora is using both values.
This option can also be specified in the Operating Pools table.
See the Knowledge Base article Long-Term Studies Using Reserve Margins for more information.
