HOMER User Tip: Modeling Critical Loads
HOMER Pro’s two distinct electric loads can be used for many different purposes (residential vs. commercial or air conditioning vs. lighting) with different efficiency options and load growth assumptions. But one of the more interesting and little-known applications of this feature is using it to distinguish between critical and non-critical loads.
In situations where there is not enough power or energy to meet the entire load, HOMER Pro reduces the power to Electric Load #2 first and treats Electric Load #1 as the critical load. Sensitivity analyses on the size of these loads and on the Maximum Capacity Shortage allows you to analyze the amount of non-critical load that will be unmet.
