Yes, to do this you need to enter function
ShapeFromDemand for the
System Load Shape variable under the high level Load Shapes branch. Once you do this you will find that an additional variable named
Load Shape appears for each demand technology branch. Here, you can specify the load shape for each technology (e.g. lighting, refrigeration, air conditioning, EVs, industrial loads, etc.) These loads will all be put together to calculate system load shapes. The easiest way to specify these is to create a library of load shapes under the General:
Yearly Shapes screen.
You can see an example of this kind of modeling by opening the Time Slice Demo model. That's available from menu option Area: Install from Cloud..
