How is peak shaving in HOMER Grid different from HOMER Pro?

Product: HOMER Grid 1.1.1

In HOMER Grid, utility component does not seem to have the Purchase Capacity option like Pro.  How would I study a Peak Shaving case with HOMER Grid? 

HOMER Grid's optimizer finds the most economic demand limit for each month, and separately if needed for on-and off- peak times.

HOMER Pro allows you to simply set a demand limit for each month or annually. 

HOMER Grid has a 'Grid Sale Limit' where you can limit how much your system is selling back to the grid.

If you want to see what the demand limit is for each month, go to the Utility Tab in the Simulation Results. Click 'Utility Bill Details'. There's a tab for Demand Limits monthly. There, you can see that what the demand has been optimized to.

Alternately, you can use the Time Series feature to visualize what the Demand Limit for each month is.
