I think I'm not understanding the functionality of the "planning reserve margin". I use different endogenous technologies, but then wanted to try setting the Planning Reserve Margin to a lower value to see what happens, compared to what I understand to be the default of 30% (above peak load). When I go to the module and "check" planning reserve margin, then set the value to 30%, I get very different results from when I just left the box unchecked. Needless to say, if I choose another, lower value, the results of the model are also very different. With user-selected Planning Reserve Margin, there is unmet demand, and the PRM (in this particular model) decreases over time from 140% (!) to 40%, although I select 30%. Is this an issue with the base year value?
