Planning Reserve Requirement Column
Column Type = Percentage (%)

This value represents the annual planning reserve margin target for the pool, where:

Planning Reserve Margin = ( ( Existing Capacity + Future Capacity + Firm Imports – Firm Exports ) / (Peak Demand) – 1 ) * 100.

You must enter this  value as a percentage (%).  Values will be reported as  a Time Series only for the monthly and annual time periods.

If the field is NULL (or this column is not present) in a long-term run that uses the Use Reserve Margin Capacity Targets option (located in the Long-Term folder of Simulation Options), the value will default to 15%, unless the pool is composed of a single zone with a reserve margin greater than 15%. For example, 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 uses both values.

You can also specify this value at the zonal level in the Zone Definition table.  

This column can also be called "Planning Reserve Margin".

See the Knowledge Base article Long-Term Studies Using Reserve Margins for more information.
