A load is a portion of the system that consumes energy. You can specify an electric load by choosing one of the three options:
Clicking on the Electric Load would open the following set up page
Click the Remove button (yellow icon on the top right) to remove the load from the schematic and model.
Primary load is the electrical load that the system must meet immediately in order to avoid unmet load. In each time step, HOMER dispatches the power-producing components of the system to serve the total primary load. Click the Electric Load button to open the Electric Load Set Up page. The details of a load in a given system are sometimes not available, so HOMER can build (simulate) a load in several ways. After HOMER creates the load, you can edit it in several ways, including modifying individual time steps.
After you have added a load, you can make changes on the Electric Load page. See the Load Profile section of the help.
